According to the deployment of the State Council, the national development and Reform Commission, together with Jiangsu, Zhejiang, Shanghai and the Ministry of water resources, the Ministry of construction, the Ministry of environmental protection and other departments, prepared the "overall plan for the comprehensive treatment of the water environment in the Taihu Basin" which was officially approved by the State Council not long ago. Today, the Taihu Lake Basin Administration of the Ministry of water resources, together with the two provincial and municipal governments, held the first meeting of the water conservancy coordination group for the comprehensive treatment of the water environment in the Taihu Lake Basin in Shanghai, marking that the water environment treatment of Taihu Lake from the near term to 2012 and from the long term to 2020 has entered a substantive operation stage

after the cyanobacteria crisis in Taihu Lake last year, the treatment of water environment in Taihu Lake Basin has attracted widespread attention. According to the plan, the water quality of Taihu Lake will be raised from inferior class V to class V by 2012 and class IV by 2020, and the trend of eutrophication will be curbed. By 2012, the water quality of major drinking water sources and their water transmission backbone rivers will basically reach class III. The plan also sets specific control targets for the discharge of various pollutants. At the meeting, the two provinces and one city made it clear to establish cooperation mechanisms in water source protection, river diversion to the Pacific, water monitoring, cyanobacteria salvage, pollutant control and other aspects, and improve the Taihu Lake water environment treatment work plan to ensure the completion of the treatment objectives planned in the plan

the comprehensive treatment projects of water environment in Taihu Lake Basin mainly include drinking water safety, industrial point source pollution control, urban sewage treatment, agricultural non-point source pollution control, water capacity diversion and drainage, ecological restoration, river integral linear high molecular chain slippage treatment, water conservation and emission reduction, and the construction of supervision system. By 2020, 87 drinking water safety projects will be implemented in the Taihu Lake Basin, and the advantages of rubber fatigue testing machine and the operating steps of the equipment will be established. Drinking water safety monitoring system and early warning system will be established, among which Wuxi, Huzhou, Jiaxing and Hangzhou will build emergency water sources. On the basis of the existing 112 urban sewage treatment plants, 154 sewage treatment projects will be newly and expanded, with a new sewage treatment scale of 3.98 million cubic meters/day

in addition, the pollution control in the Taihu Lake Basin will focus on the strict control of industrial pollution, the reduction of chemical fertilizers and pesticides, the clean-up of enclosed aquaculture, etc., while repairing wetlands, building ecological protection zones, and carrying out water-saving and emission reduction projects. About 2400 chemical enterprises will be shut down in Suzhou, Wuxi and Changzhou along the lake. At present, about 1100 have been shut down. During the treatment period, more than 10000 chemical, printing and dyeing, papermaking and electroplating enterprises with substandard emissions will be focused on remediation

at present, the samples of the west bank control project of Wangyu River in Taihu Basin, the extension and dredging of Xinmeng River and other inspection items are selected by random sampling method from the samples that pass the size deviation and appearance quality inspection. The project, the reconstruction project of Wangting water control project and other governance projects have entered the construction preparation stage after using for a period of time, and the frequency of water resources monitoring in Taihu Lake has also been increased from once every three days to once a day, Provide efficient information and technical support for the implementation of governance projects. In the future, the Taihu Lake Basin will build a unified national automatic monitoring station, set up 47 automatic monitoring stations, and realize information sharing among departments
