淀山湖水生态蓝藻治理研究

淀山湖是上海最大的淡水湖泊,是上海市重要水上通道,也是上海市的重要水源地之一,有“东方日内瓦湖”之称。随着周边乡镇农药化肥及工业废水等排入,湖水局部富营养化现象日益严峻,同时也带来了蓝藻水华污染的情况。通过前端的监测预警对蓝藻的暴发周期及暴发规模有效预估,统一规划设置蓝藻导流区、聚集区及打捞区,利用蓝藻高压囊团破裂,自然沉底消亡及纳米气泡分离脱水处理等技术手段,结合后期的常态化管理,改善淀山湖生态环境,深刻理解习近平总书记提出的“绿水青山就是金山银山”所蕴含着绿色生态是最大财富的深刻道理。

As the largest fresh water lake in Shanghai,Dianshan Lake is an important waterways and one of the important water sources of Shanghai.It is also known as"Lake Geneva of the East".With the discharge of pesticides,fertilizers and industrial wastewater from surrounding villages and towns,the local eutrophication of the lake is becoming more and more serious,thus bringing the pollution of cyanobacteria bloom.Through the monitoring and early warning at the front end,we can effectively predict the outbreak cycle and scale of cyanobacteria,uniformly plan and set up the diversion area,accumulation area and salvage area of cyanobacteria,and adopts measures such as the rupture of high pressure cysts of cyanobacteria,natural bottom extinction and nano-bubble separation/dehydration treatment,so as to improve the ecological environment of Dianshan Lake based on the later normal management,thereby deeply understand General Secretary Xi Jinping's idea that"Green mountainsin clean wateraregold and silver mountains",which contains the profound truth that green ecology is the greatest wealth for mankind.
