,拯救我们的家园环境工程,环境工程,水体污染控制,水体污染的控制措施，除加强污染源的管理，以降低废水量和污染量外，政府应制定和颁布法规以控制废水的排放，如中国政府制定和颁布了中华人民共和国水污染防治法、工业“三废”排放试行标准等法规。城镇应建设完善的排水管系和废水处理厂，并制定和实施管理制度。工业布局和工艺要考虑环境要求。生产废水必须处理后出厂（见工业废水治理），废水再用，特别是建立废水灌溉系统，是防止废水污染水体的有效途径。,水体污染控制,水体污染物主要有：病原体，如病菌、病毒和寄生虫卵等；来源于动植物的有机物，如动植物排泄物、动植物残体、机体的组分等，它们在水体中的细菌作用下消耗溶解氧；植物养料，主要有氮、磷化合物，将使潺湲的水体出现富营养化；有毒有害的化学品，如含氯农药（DDT、六六六等）、表面活性剂、重金属盐类、放射性物质等；其他，如油脂、酸、碱、温水，悬浮物等（见废水水质）。,固体废物处置,固体废物的处置方法,掩埋,焚化,加工利用,掩埋,焚化,加工利用,固体废物处置,噪声污染控制,干扰人们休息、学习、生活和工作，甚至影响健康的声音，统称为噪声。噪声由许多纯音组成。纯音(单频率的声音)的声压(p)可用与基准声压(p0接近一般人的听阈，通常采用p0210-5帕)相比的声压级（Lp）表示，单位为分贝（dB），它的数学表达式为Lp201g(p/p0)。噪声强弱的测定较复杂，不但要结合各纯音的频率，还要结合人的主观感受。有多种方法量度，一般采用声级，单位也用分贝。声级可用声级计直接测得。声级增加40分贝，声压约增百倍，干扰大大增加。一般认为低于85分贝时不致影响听力。喷气飞机起飞时的噪声达150分贝，使耳鼓发痛。160分贝的噪声使人致聋。噪声还影响人的中枢神经系统和心血管系统，会导致神经衰弱和心血管病。噪声还影响讲话和电话的使用。可使人致聋的噪声还影响某些仪表的使用。,噪声污染控制,噪声主要来自机器（工业噪声）和交通工具（交通运输噪声）。控制噪声首先是不用喧嚣的设备：或则改革工艺，如改铆接为焊接；或则改换机械，如用压桩机替代打桩机。其次是革新机械的构造和材料，如提高部件精度减少碰撞，用非金属材料替代金属材料，传动部件用弹性构件，整机采用隔振机座或隔声罩，排气口设消声器，交通工具外形采用流线型等。再次是正确操作，如正确使用润滑剂，正确使用喇叭等音响设备。建立隔声屏障（如墙、土丘）或建筑表面多用吸声、隔声材料，以及城市合理规划等等，也是有效的措施（见飞机场环境保护）。,大气污染控制,2007,2008,2009,2010,近年空气质量,Clicktoedittitlestyle,Descriptionofthecontents,Textinhere,ThemeGalleryisaDesignDigitalContent&ContentsmalldevelopedbyGuildDesignInc.,Textinhere,ThemeGalleryisaDesignDigitalContent&ContentsmalldevelopedbyGuildDesignInc.,Textinhere,ThemeGalleryisaDesignDigitalContent&ContentsmalldevelopedbyGuildDesignInc.,Textinhere,ThemeGalleryisaDesignDigitalContent&ContentsmalldevelopedbyGuildDesignInc.,Clicktoedittitlestyle,Contents01,Contents02,Contents03,Contents04,Contents05,Contents06,0%20%40%60%80%100%,18.5%,17.5%,8.7%,23.6%,63.6%,84.3%,ThemeGalleryisaDesignDigitalContent&ContentsmalldevelopedbyGuildDesignInc.,Clicktoedittitlestyle,Textinhere,Textinhere,Textinhere,ThemeGalleryisaDesignDigitalContent&ContentsmalldevelopedbyGuildDesignInc.,ClicktoaddText,Clicktoedittitlestyle,ThemeGalleryisaDesignDigitalContent&ContentsmalldevelopedbyGuildDesignInc.,Titleinhere,2.Descriptionofthecompanyssubcontents,ThemeGalleryisaDesignDigitalContent&ContentsmalldevelopedbyGuildDesignInc.,1.Descriptionofthecompanyssubcontents,Clicktoedittitlestyle,ThemeGalleryisaDesignDigitalContent&ContentsmalldevelopedbyGuildDesignInc.,Titleinhere,Titleinhere,Titleinhere,Titleinhere,A,B,C,D,Clicktoedittitlestyle,Descriptionofthecontents,ThemeGalleryisaDesignDigitalContent&ContentsmalldevelopedbyGuildDesignInc.,ThemeGalleryisaDesignDigitalContent&ContentsmalldevelopedbyGuildDesignInc.,ThemeGalleryisaDesignDigitalContent&ContentsmalldevelopedbyGuildDesignInc.,Titleinhere,Titleinhere,Titleinhere,Clicktoedittitlestyle,Textinhere,Textinhere,Textinhere,Textinhere,Textinhere,Textinhere,Textinhere,Textinhere,Contents,Contents,Contents,Contents,Contents,ThemeGalleryisaDesignDigitalContent&ContentsmalldevelopedbyGuildDesignInc.,Clicktoedittitlestyle,ThemeGalleryisaDesignDigitalContent&ContentsmalldevelopedbyGuildDesignInc.,DescriptionofthecontentsDescriptionofthecontents,DescriptionofthecontentsDescriptionofthecontents,DescriptionofthecontentsDescriptionofthecontents,ContentTitle,ContentTitle,ContentTitle,Clicktoedittitlestyle,Pleasewritedownofasloganforavisionofacompanyinshortly.,Pleasewritedownofasloganforavisionofacompanyinshortly.,Pleasewritedownofasloganforavisionofacompanyinshortly.,Pleasewritedownofasloganforavisionofacompanyinshortly.,Vision01,Vision03,Vision02,Vision04,CompanyLOGO,Clicktoedittitlestyle,Clicktoedittitlestyle,Titleinhere,ThemeGalleryisaDesignDigitalContent&ContentsmalldevelopedbyGuildDesignInc.,Descriptionofthecontents,Descriptionofthecontents,Descriptionofthecontents,Descriptionofthecontents,Titleinhere,Titleinhere,Titleinhere,Service01,Service02,Service03,LOGO,ThemeGalleryisaDesignDigitalContent&ContentsmalldevelopedbyGuildDesignInc.,Clicktoedittitlestyle,Clicktoedittitlestyle,Titleinhere,AddTitle,AddTitle,AddTitle,AddTitle,DescriptionofthecontentsDescriptionofthecontents,DescriptionofthecontentsDescriptionofthecontents,Textinhere,Textinhere,Textinhere,Textinhere,DescriptionofthecontentsDescriptionofthecontents,DescriptionofthecontentsDescriptionofthecontents,Clicktoedittitlestyle,ThemeGalleryisaDesignDigitalContent&ContentsmalldevelopedbyGuildDesignInc.,Title,Textinhere,Textinhere,Textinhere,Textinhere,Clicktoedittitlestyle,Growth,Start,Jump,200820072006,200520042003,200220012000,DescriptionofthecontentsDescriptionofthecontentsDescriptionofthecontents,DescriptionofthecontentsDescriptionofthecontentsDescriptionofthecontents,DescriptionofthecontentsDescriptionofthecontentsDescriptionofthecontents,Descriptionofthecontents,DescriptionofthecompanysproductsDescriptionofthecompanysbusinessDescriptionofthecompanystechnology,DescriptionofthecompanysproductsDescriptionofthecompanysbusinessDescriptionofthecompanystechnology,DescriptionofthecompanysproductsDescriptionofthecompanysbusinessDescriptionofthecompanystechnology,DescriptionofthecompanysproductsDescriptionofthecompanysbusinessDescriptionofthecompanystechnology,Descriptionofthecontents,Descriptionofthecontents,Descriptionof
