The design is mainly directed against the Nanjing in Jiangsu Province and the surrounding areas, the Yangtze River valley city tap water design, source water from the Yangtze River. the water sector is facing deteriorating water quality and treatment, the improvement of water quality requirements. Measures taken by : calling for pollution because current water treatment technology can not yet technically what water can do, not the other costs of the economy, So to a permanent solution, and actively look for measures to enhance the process, so that the treated water can meet the safety and health requirements. Yangtze River dominant wind direction for the whole Northeast, the summer winds led to the southeast, sub-led East southeast; Winter led the Northeast, Yangtze River water in recent years contains a lot of sand, water turbidity increased significantly. Design of the scale of the production of 100,000 tons of water plant design.
