佛山某镇污水处理厂可行性研究报告.doc

off here, the conductor said. This is as far as we go. Is this Woodford Green ? I asked. Oh dear, said the conductor suddenly. I forgot to put you off. It doesnt matter, I said. Ill get off here. We are going back now, said the conductor. Well, in that case, I prefer to stay on the bus, I answered.Lesson51 Reward for virtue 对美德的奖赏My friend, Herbert, has always been fat, but things got so bad recently that he decided to go on a diet. He began his diet a week ago. First of all, he wrote out a long list of all the foods which were forbidden. The list included most of the things Herbert loves: butter, potatoes, rice, beer, milk, chocolate, and sweets. Yesterday I paid him a visit. I rang the bell and was not surprised to see that Herbert was still as fat as ever. He led me into his room and hurriedly hid a large parcel under his desk. It was obvious that he was very embarrassed. When I asked him what he was doing, he smiled guiltily and then put the parcel on the desk. He explained that his diet was so strict that he had to reward himself occasionally. Then he showed me the contents of the parcel. It contained five large bars of chocolate and three bags of sweets! Lesson52 A pretty carpet 漂亮的地毯We have just moved into a new house and I have been working hard all morning. I have been trying to get my new room in order. This has not been easy because I own over a thousand books. To make matters worse, the room is rather small, so I have temporarily put my books on the floor. At the moment, they cover every inch of floor space and I actually have to walk on them to get in or out of the room. A short while ago, my sister helped me to carry one of my old bookcases up the stairs. She went into my room and got a big surprise when she saw all those books on the floor. This is the prettiest carpet I have ever seen, she said. She gazed at it for some time then added, You dont need bookcases at all. You can sit here in your spare time and read the carpet! Lesson53 Hot snake 触电的蛇At last firemen have put out a big forest fire in California. Since then, they have been trying to find out how the fire began. Forest fire are often caused by broken glass or by cigarette ends which people carelessly throw away. Yesterday the firemen examined the ground carefully, but were not able to find any broken glass. They were also quite sure that a cigarette end did not start the fire. This morning, however, a fireman accidentally discovered the cause. He noticed the remains of a snake which was wound round the electric wires of a 16,000-volt power line. In this way, he was able to solve the mystery. The explanation was simple but very unusual. A bird had snatched up the snake from the ground and then dropped it on to the wires. The snake then wound itself round the wires. When it did so, it sent sparks down to the ground and these immediately started a fire.Lesson54 Sticky fingers 粘糊的手指After breakfast, I sent the children to school and then I went to market. It was still early when I returned home. The children were at school, my husband was at work and the house was quiet. So I decided to make some tarts for tea. In a short time I was busy mixing butter and flour and my hands were soon covered with sticky pastry. At exactly that moment, the telephone rang. Nothing could have been more annoying. I picked up the receiver between two sticky fingers and was dismayed when I recognized the voice of Mrs Bates. It took me ten minutes to persuade her to ring back later. At last I hung up the receiver. What a mess! There was pastry on my fingers, on the telephone, and on the door-knobs. I had no sooner got back to the kitchen than the door-bell rang loud enough to wake the dead. This time it was the postman and he wanted me to sign for a registered letter !Lesson55 Not a gold mine 并非金矿Dreams of finding lost treasure almost came true recently. A new machine called The Revealer has been invented and it has been used to detect gold which has been buried in the ground. The machine was used in a cave near the seashore where-it is said-pirates used to hide gold. The pirates would often bury gold in the cave and then fail to collect it. Armed with the new machine, a search party went he did not like it. She enjoyed herself making the assistant bring almost everything in the window before finally buying the dress she had first asked for.Lesson58 A blessing in disguise? 是因祸得福吗？The tiny village of Frinley is said to possess a cursed tree. Because the tree was mentioned in a newspaper, the number of visitors to Frinley has now increased. The tree was planted near a church fifty years ago, but it is only in recent years that it has gained an evil reputation. It is said that if anyone touches the tree, he will have bad luck; if he picks a leaf, he will die. Many villagers believe that the tree has already claimed a number of victims. The vicar has been asked to have the tree cut down, but so far he has refused. He has pointed out that the tree is a useful source of income as tourists have been coming from all parts of the country to see it. In spite of all that has been said, the tourists-have been picking leaves and cutting their names on the tree-trunk. So far, not one of them has been struck down by sudden death!Lesson59 In or out ？ 进来还是出去？Our dog, Rex, used to sit outside our front gate and bark. Every time he wanted to come into the garden he would bark until someone opened the gate. As the neighbours complained of the noise, my husband spent weeks training him to press his paw on the latch to let himself in. Rex soon became an expert at opening the gate. However, when I was going out shopping last week, I noticed him in the garden near the gate. This time he was barking so that someone would let him out ! Since then, he has developed another bad habit. As soon as he opens the gate from the outside, he comes into the garden and waits until the gate shuts. Then he sits and barks until someone lets him out. After this he immediately lets himself in and begins barking again. Yesterday my husband removed the gate and Rex got so annoyed we have not seen him since. Lesson60 The future 卜算未来At a village fair, I decided to visit a fortune-teller called Madam Bellinsky. I went into her tent and she told me to sit down. After I had given her some money, she looked into a crystal ball and said: A relation of yours is coming to see you. She will be arriving this evening and intends to stay for a few days. The moment you leave this tent, you will get a big surprise. A woman you know well will rush towards you. She will speak to you and then she will lead you away from this place. That is all. As soon as I went outside, I forgot all about Madam Bellinsky because my wife hurried towards me. Where have you been hiding ? she asked impatiently. Your sister will be here in less than an hour and we must be at the station to meet her. We are late already. As she walked away, I followed her out of the fair. Lesson61 Trouble with the Hubble 哈勃望远镜的困境In future, astronauts will be required to descend from a spaceship while it is still in space and to return to it. The ability to do this will be necessary in future flights to distant planets. Scientists are now trying to discover if this is possible. The spaceship Astra which left the earth a short time ago, will be travelling three hundred miles into space. At a certain point, the Astra will stop for a short time and an astronaut will attempt to leave the stationary spaceship and then return to it. We shall not know whether the experiment has been successful until we have received a radio message. The first message is expected to arrive at 7 oclock this evening. By that time, the Astra will have been flying through space for seventeen hours and will have circled the earth a great many times. When the first radio messages have been received, the results of the trip will be announced immediately.Lesson62 After the fire 大火之后Firemen had been fighting the forest fire for nearly three weeks before they could get it under control. A short time before, great trees had covered the countryside for miles around. Now, smoke still rose up from the warm ground over the desolate hills. Winter was coming on and the hills threatened the surrounding villages with destruction, for heavy rain would not only wash away the soil but would cause serious floods as well. When the fire had at last been put out, the forest authorities ordered several tons of a special type of grass-seed which would grow quickly. The seed was sprayed over the ground in huge quantities by aeroplanes. The planes had been planting seed for nearly a month when it began to rain. By then, however, in many places the grass had already taken root. In place of the great trees which had been growing there for centuries, patches of green had begun to appear in the blackened soil. Lesson63 She was not amused 她并不觉得好笑Geoffrey Hampden has a large circle of friends and is very popular at parties. Everybody admires him for his fine sense of humor-everybody, that is, except his six-year-old daughter, Jenny. Recently, one of Geoffreys closest friends asked him to make a speech at a wedding reception. This is the sort of thing that Geoffrey loves. He prepared the speech carefully and went to the wedding with Jenny. He had included a large number of funny stories in the speech and, of course, it was a great success. As soon as he had finished, Jenny told him she wanted to go home. Geoffrey was a little disappointed by this but he did as his daughter asked. On the way home, he asked Jenny if she had enjoyed the speech. To his surprise, she said she hadnt. Geoffrey asked her why this was so and she told him that she did not like to see so many people laughing at him!Lesson64 The Channel Tunnel 海峡隧道In l858, a French engineer, Aime Thome de Gamond, arrived in England with a plan for a twenty-one mile tunnel across the English Channel. He said that it would be possible to build a platform in the centre of the Channel. This platform would serve as a port and a railway station. The tunnel would be well-ventilated if tall chimneys were built above sea-level. In 1860, a better plan was put forward by an Englishman, William Low. He suggested that a double railway tunnel should be built. This would solve the problem of ventilation, for if a train entered this tunnel, it would draw in fresh air behind it. Forty-two years later a tunnel was actually begun. If, at the time, the British had not feared invasion, it would have been completed. Recently, there has again been great interest in the idea of a Channel Tunnel. If it is built, it will connect Britain to Europe for the first time in history.Lesson65 Jumbo versus the police 小象对警察Last Christmas, the circus owner, Jimmy Gates, decided to take some presents to a childrens hospital. Dressed up as Father Christmas and accompanied by a guard of honour of six pretty girls, he set off down the main street of the city riding a baby elephant called Jumbo. He, should have known that the police would never allow this sort of thing. A policeman approached Jimmy and told him he ought to have gone along a side-street as Jumbo was holding up the traffic. Though Jimmy agreed to go at once, Jumbo refused to move. Fifteen policemen had to push very hard to get him off the main street. The police had a difficult time, but they were most amused. Jumbo must weigh a few tons, said a policeman afterwards, so it was fortunate that we didnt have to carry him. Of course, we should arrest him, but as he has a good record, we shall let him off this time.Lesson66 Sweet as honey! 像蜜一样甜！The Hatheld Puffin is a modern aero-plane, but its designer, Mr John Wimpenny, is finding it difficult to get it off the ground. The reason for this is that this plane is also a bicycle. Its pilot has to pedal hard to get it into the air. After Mr Wimpenny had the plane built, it was tested thoroughly. In 1961, it was the first man-powered aircraft to fly half a mile. While being flown by a champion amateur cyclist in 1963, the plane crashed on an airfield. Since then, Mr Wimpenny has had it rebuilt. He has had the length of the wings increased so that they now measure 93 feet-almost as long as those of a Dakota. Many people have shown interest in this new and unusual sport. But though air cyclists may learn how to fly over short distances, and may, eventually, even get across the English Channel, it is doubtful whether they will ever cycle across the Atlantic.Lesson67 Volcanoes 火山Haroun Tazieff the Polish scientist, has spent his life-time studying active volcanoes and deep caves in all parts of the world. In 1948, he went to lake Kivu in the Congo to observe a new volcano which he later named Kituro. Tazieff was able to set up his camp very close to the volcano while it was erupting violently. Though he managed to take a number of brilliant photographs, he could not stay near the volcano for very long. He noticed that a river of liquid rock was coming towards him. It threatened to surround him completely, but Tazieff managed to escape just in time. He waited until the volcano became quiet and he was able to return two days later. This time, he managed to climb into the mouth of Kituro so that he could take photographs and measure temperatures. Tazieff has often risked his life in this way. He has been able to tell us more about active volcanoes than any man alive. Lesson68 Persistent 纠缠不休I crossed the street to avoid meeting him, but he saw me and came running towards me. It was no use pretending that I had not seen him, so I waved to him. I never enjoy meeting Bert Dykes. He never has anything to do. No matter how busy you are, he always insists on coming with you. I had to think of a way of preventing him from following me around all morning.Hullo, Bert, I said. Fancy meeting you here !Hullo, Elizabeth, Bert answered. I was just wondering how to spend the morning-until I saw you. Youre not busy doing anything, are you ? No, not at all, I answered. Im going to. .Would you mind my coming with you ? he asked, before I had finished speaking. Not at all, I lied, but Im going to the dentist. Then Ill come with you, he answered. Theres always plenty to read in the waiting room !lesson69 But not murder! 并非谋佛山某镇污水处理厂可行性研究报告前 言某镇地处珠江三角洲腹地，位于南海区西部，东与狮山镇相连，南与西樵镇相接，西、北与三水区接壤。距广州38km，佛山22km，北江支流从镇的东边流过，南海区东西干线连接某镇城区与广州珠江隧道芳村口，每天有数十班客车往返于广州、佛山和西樵之间，水陆交通方便。近些年来，随着某镇的经济的发展，排放的生产生活污水水量也随之增长；而某镇城区基本上未铺设污水收集管道，大量的生产生活污水未经收集处理直接排放入水体，对周围水体造成严重污染。根据南海区环境规划总体要求及某镇环境规划要求，某镇近期即将实施建设城区生活污水收集管道和污水处理厂，以完善某镇的污水处理系统，改善某镇的水环境。基于上述背景，2006年3月，受佛山市某镇污水处理有限公司委托，我院积极组织技术力量，对工程规模及原有方案进行了进一步的综合分析和研究，相应地调整了技术方案，最终编制了佛山市某镇城区污水处理工程的可行性研究报告。本研究报告主要结论如下：（1）污水厂处理规模根据建设方提供的资料，结合实际调研情况，确定某镇城区污水处理厂设计规模为6万吨/日，分期建设。本可行性研究报告主要考虑一期（2007年）处理规模1.0万吨/日的设计。（2）进出水水质结合调查数据、城镇污水厂处理厂污染物排放标准（GB18918-2002）,确定某镇城区污水处理厂进出水水质如下：设计进、出水水质一览表序号设计指标进水水质出水水质去除率(%)1CODCr(mg/L)30060802BOD5(mg/L)15020873SS(mg/L)20020904NH3-N(mg/L)308735TP(mg/L)31.067（3）污水处理工艺本方案推荐采用CASS工艺作为某镇城区污水处理厂污水处理的主体工艺，同时根据城市污水处理工程项目建设标准，经二级处理后消毒排放。（4）污泥处理工艺结合一期1.0万吨/日建设规模的实际情况，建议设储泥池，通过螺杆泵提升进入浓缩脱水一体化机进行浓缩脱水，脱水后污泥外运填埋处理。（5）污水厂主要技术经济指标序号名 称单位数量1一期厂区占地面积公顷0.8472建构筑物占地面积公顷0.3183建筑系数%14.04道路广场占地面积公顷0.2255绿化占地面积公顷0.1696绿化系数%307总投资:万元1437.821 概 述1.1 编制依据及基础资料1.1.1 编制依据佛山市某镇城区污水处理厂工程设计委托书。1.1.2 基础资料1、佛山市某镇总体规划修编某镇人民政府，深圳市城市规划设计研究院 2006年9月编制2、南海市“十五”环境保护规划南海市环境保护局 1999年12月编制3、城市污水处理及污染物防治技术政策建设部国家环保总局科技部 建城【2004】24号文件4、市政工程设计管理标准建设部城市建设司5、佛山市某镇污水处理专项规划某镇人民政府，同济大学建筑设计研究院 2007年3月编制6、某镇自来水公司提供有关工业园及附近村委的近几年的用水量7、某镇地形图(1:10000)8、其它某镇的基础资料1.2 采用的主要规范和标准1.室外排水设计规范（GB50014-2006）2.泵站设计规范 GB/T50265-973.建筑给水排水设计规范 GB50015-2003 4.地表水环境质量标准 GB3838-20025.城镇污水处理厂污染物排放标准 GB18918-20026. 城市污水处理工程项目建设标准（修订） 2001北京7.城市污水处理厂污水、污泥排放标准 CJ3025-938.城市污水处理厂附属建筑和附属设备设计标准 CJJ31-899.城市污水处理厂运行、维护及其安全技术规程 CJJ60-9410.建筑结构荷载规范 GB50009-200111.建筑地基处理技术规范 JGJ79-200212.混凝土结构设计规范 GB50010-200213.建筑抗震设计规范 GB50011-200114.砌体结构设计规范 GB50003-200115.钢结构设计规范 GB50017-200316.给水排水工程结构设计规范 GB50069-200217.建筑桩基技术规范 JGJ94-9418.预应力混凝土结构规范19.混凝土结构工程施工质量验收规范 GB50204-200220.给水排水构筑物工程施工及验收规范 GBJ141-9021.地基与基础工程质量验收规范 GB50202-200222.建筑地基基础设计规范 GB50007-200223.采暖通风与空气调节设计规范 GBJ1987 2001年版24.暖通空调规范实施手册25.10kV及以下变电所设计规范 GB500539426.低压配电设计规范 GB500549527.供配电系统设计规范 GB500529528.电力工程电缆设计规范 GB502179429.电力装置的继电保护和自动装置设计规范 GB500629230.工业企业照明设计标准 GB500349231.爆炸和火灾危险环境电力装置设计规范 GB50058-9232.建筑物防雷设计规范 GB5005794(2000版)33.工业与民用电力装置的接地设计规范 GBJ658334.自动化仪表选型规定 HG 2050792 35.仪表供电设计规定 HG-T 20509-2000 36.仪表系统接地设计规定 HG 205132000 37.建筑防雷设计规范 GB50057-94 2000版38.计算机机房设计规范 GB50174-9339.分散型控制系统工程设计规范 HG20573 40.电气装置的电测量仪表装置设计规范 GBJ 639041.分散型控制系统工程设计规定 HG/T 20573-9542.控制室设计规定 HG 20508200043.信号报警、联锁系统设计规定 HG 20511200044.建筑设计防火规范 GB50016-20061.3 编制范围及年限1.3.1 编制范围本可行性研究编制范围：佛山市某镇城区污水处理厂工程。本工程服务范围为：某镇中心城区。1.3.2 编制年限本工程编制年限：近期(一期)：2007年2010年远期(二期)：2010年2020年1.4 编制目的编制目的是对工程设计规模、污水水质、处理厂厂址、污水污泥处理工艺等进行技术可靠性、经济合理性及实施可能性的多方案比较和论证，在此基础上，提出推荐方案，使所选方案科学合理、技术先进、处理效果好、运行稳妥可靠、占地面积小、造价省、运行成本低。最终使得该项工程的社会效益、环境效益和经济效益达到最佳统一。1. 贯彻国家有关环境保护政策，符合国家的有关法规、规范及标准；2. 经处理后排放的污水水质符合国家和地方的有关排放标准和规定，符合环境影响评价的要求；3. 在佛山市城市总体规划及佛山市污水处理工程建设规划的指导下进行项目的可行性研究；4. 根据现有的排水体制和水环境保护的要求，综合规划和选择合理的排水体制，使工程具有可实施性；5. 因地制宜地采用先进的污水处理和污泥处理的新工艺、新技术、新设备和新材料；6. 采取全面设计、分期实施的原则，既考虑近期的可操作性又考虑中、远期合理性，使工程建设与城市的发展相协调，既保护环境，又最大程度地发挥工程效益；7. 采用先进地节能技术，降低污水处理厂的能耗及运行成本；8. 优先采用集成度高的污水处理工艺，以便实现模块化设计，以利于污水处理厂的分期建设和扩展；9. 采用先进、可靠的自动化控
