As economic construction, construction of urban and rural development and population increase, water continued to grow, increasing water supply and demand contradiction. Due to the large number of industrial waste and domestic sewage discharged into water bodies, is seriously ` the water environment pollution, water shortages and deterioration of water quality has become a restricted economy, destruction of ecological environment construction and urban and rural development, highlight issues affecting people's lives and their own health. Design for engineering design technology of industrial wastewater treatment plant, wastewater treatment plant size for 15000m3/d, major source of sewage for sewage ...
