The first professional sludge treatment and disposal company in the country, Sanshui Environmental Protection Company, was established in Chongqing recently. The company is mainly built sludge treatment center next to each sewage treatment plant, through the deep processing of sludge to control the secondary pollution, save the purpose of land disposal.
According to the person in charge of Chongqing Water Group, as a by-product of sewage treatment, sludge contains a large amount of harmful substances such as bacteria, parasites, and heavy metals. If the landfill is simply buried in the traditional way, it will not only occupy a large amount of land and cause adverse effects on the normal operation of the landfill, but also cause serious secondary pollution due to the high concentration of pollutants in the sludge. It is reported that because undried sludge can easily clog the garbage leachate collection system and affect the normal operation of vehicles and landfill machinery, some municipal solid waste landfills in Chongqing have started rejecting sludge, causing sewage treatment plants to generate daily. The large amount of sludge can only be accumulated in situ and the secondary pollution is more serious. In the future, as the scale of sewage treatment increases, the amount of sludge generated each day will also increase. According to industry estimates, the total amount of sludge produced by the sewage treatment plants in the main urban area of ​​Chongqing will reach 988 cubic meters per day in 2010 and 2,380 cubic meters per day in 2020; if we count the Three Gorges reservoir area and its affected areas, we will In the year, the city's sewage treatment plant produced 1,707 cubic meters of sludge per day and climbed to 3,244 cubic meters/day by 2020.
As a project construction project for sludge treatment and disposal in Chongqing in the future, the company will first establish a sludge treatment center for the sewage treatment plants in Chongqing, with a designed treatment capacity of 630 cubic meters per day, which will be put into operation before 2010. In accordance with the relevant plans of the Chongqing Municipal Government, after this, Chongqing Water Group will also build four sludge treatment centers in the main city area to ensure the normal operation of the city's sewage treatment plants, and to manage and protect the Three Gorges reservoir area and the middle and lower reaches of the Yangtze River. Water quality, ecological environment.
