/ / / /解读景观水体水质恶化的原因及治理Interpretation of landscape water quality deterioration causes and governance 经过对全市几个公园内的景观水体调查研讨发现，招致景观水水质恶化的缘由有很多。总体上可分以下几种：Through to several parks in the city landscape water survey research found that there are many cause the cause of the landscape water quality deterioration. In general can be divided into the following kinds: 景观水的水源水质较差。普通景观水的水源主要来自三个方面：降水、地表水、中水。大局部日常补充水量以降水聚集为主，而周围聚集的降水把地表很多污染物都溶解在内，使得景观水源先天质量较差。Landscape water water water quality is poorer. Ordinary landscape water source of water comes mainly from three aspects: the precipitation, surface water, and water. Big local mainly gather daily supplement water to precipitation, and precipitation dissolve the surface many pollutants are gathered around, make landscape water born poor quality. 四周污染源对其污染。景观水体污染物主要来源于周围小区内居民日常生活所排放生活污水、生活渣滓、建筑渣滓及其渗滤液、漂物和施工尘土等。特别是生活污水中含有大的有机污染物及氮、磷等植物营养物，植物营养物进入自然水体后将恶化水体水质，加速水体的富营养化过程，影响水面的应用。Pollution sources around the pollution. Landscape water body pollution mainly comes from the surrounding neighborhood residents daily life in the discharge of sewage, life scum scum and its leachate and floating dust content and construction, etc. Especially sewage contains large organic pollutants and plant nitrogen, phosphorus and other nutrients, plant nutrients into the natural water body after the deteriorating water quality, accelerate the eutrophication of water body of the process, affect the water application. 水池防渗处置毁坏景观水生态系统。目大局部的人工湖由于思索到防渗等问题，湖底多为硬质底。关于需求泥土才干生长的水生植物而言，其种植、生长都会有诸多限制。很多水域由于防渗层铺设质量不过关，形成人工湖水流失过快，或管理过程中补水不及时。水生植物因干涸而生长不良以至枯死，既没有发挥净水作用又毁坏观景效果。Water pond anti-seepage disposal of destruction of landscape ecological system. Orders, big local artificial lake think due to problems such as seepage control, the bottom is more hard. About the demand for talents growth of aquatic plants, soil its cultivation, growth will have limitations. Many waters due to seepage control layer paving quality closes nevertheless, form a artificial lake water loss too fast, or management in the process of filling water in a timely manner. Aquatic plant growth bad due to dry up and die, both did not play a role of water purification and ruin the view effect. 游客人为的毁坏。游客的一些行为，也是招致水质恶化的缘由之一。比方向水中丢弃渣滓；为了垂钓，向水体撒过多的鱼饵，这些多余的鱼饵也会形成水体的污染，这些种种行为都会严重地污染景观水。Tourists artificially damaged. Some behavior of the tourists, is also one of the reason to cause water quality deterioration. Than the direction of the water discarding the dross; To fishing, too much water and fish bait, these extra bait will form water body pollution, these actions will be serious pollution of landscape water. 设计的不合理。由于在水景设计与思索不周，人工湖中经常会呈现死角，而死角中的水由于缺乏活动，水质常常最容易恶化。各种污染物将会堆积在死角，并渐渐地污染整个人工湖，死角成人工湖的一个内部污染深，因而，在一个人湖中假如死角越多，水质恶化得越快。Design is not reasonable. Due in waterscape design and thought, artificial lake often presents the dead Angle, and the water in the corner because of lack of activity, water is often the most easy to deterioration. All kinds of pollutants will be piled up in blind Angle, and slowly pollution the whole lake, a corner into a man-made lake deep internal pollution, therefore, the more in if a corner in a lake, the faster water quality deterioration. 公开水的污染。随着工农业的不时开展，越来越多的污染(如氮、磷、重金属离子等等)渗入了公开，污染了公开水。往常我国公开水的污染已相当普遍而严重。而大局部的景观水又是与公开水相通的，因而招致景观水的蜕变也是显而易见的。Open the pollution of water. As from time to time to carry out the agriculture and industry, more and more pollution, such as nitrogen, phosphorus, heavy metal ion, etc.) into the public, polluted the open water. Always open in our country is quite common and serious water pollution. And the big local landscape water is that link the mines with open water, and thus incur the metamorphosis of landscape water is obvious. 景观水体污染预防的办法Landscape water body pollution prevention measures 要坚持景观水体的清洁，使之到达规则的景观文娱用水水质标请求，必需对可能形成该水体污染的上述污染物的污染源严加控制，详细主要倡议措施如下：Insist on landscape water clean, and make it reach the rules of recreational water quality standard request, necessary for the sources of pollutants of the water pollution can be formed kept under strict control, the main initiative measures in detail as follows: 加大政府投入，建好城市污水设备。充沛应用如今国度环保的新形势，多方面筹集资金，规划建立好城市污水处置厂和雨污别离管道，使景观四周的污水经过处置到达景观水质量规范后再排入土工膜；对前10分钟的降水也要归入污水处置厂处置，这样能有效的遏制空中堆积物对景观水的污染。Increase government investment, build urban sewage equipment. Abundant application country environmental protection of the new situation nowadays, various raise money, planning and setting up urban sewage disposal plant and rain sewage pipe separation, to make the sewage after treatment reaches the landscape around the landscape water quality standard before discharge into; For 10 minutes before the precipitation will go into the disposal of the sewage disposal factory, so can effectively curb air accumulation of landscape water pollution. 增强执法。管好四周污染源。保证水体周围区域内小区、饭店等污染源产生的生活污水必需排入城市下水道系统泰山石，进城市污水处置厂处置，不能直排入景观水体；在有些水体周围下水道系统还不完善，与现有市政下水道系统没有衔接的状况下，周边污染源必需设立独立污水处置站对其污水停止处置，请求改道外排。也应严禁在湖四周左近堆放生活或建筑渣滓。以免渣滓飘浮物经风吹到湖体水面或渣滓渗滤液直接流入湖体，对湖体水质形成不同水平的污染2.3、做好调度，保证地表径流水质质量水处理药剂。地表径流雨水含有较多有机物和无机尘土，特别降雨前非常钟地表径流水中污染物含量更高，应排入城市雨水管道扫除。不能直接排入景观水体，若直接排入景观水领会形成淤积或水体不同水平的污染。Strengthen law enforcement. Manage pollution sources around. Ensure water area around the village of pollution such as sewage, the hotel must be discharged into urban sewage system, into the disposal of urban sewage disposal factory, not straight into the landscape water body; Around some water sewer system is not perfect, and the existing municipal sewer system without cohesion under the condition of the surrounding pollution sources must set up independent sewage disposal station with its sewage stop disposal, request the diversion discharge. Should also be forbidden or full life piled up construc
