- Abstract:
- Laundry wastewater contains lots of pollutants such as organic matter and ammonia nitrogen. Due to the preliminary design defect and later ineffective management in parts of China, there is large amount of balcony laundry wastewater entering the river, which may cause serious pollution of the water environment. At present, balcony laundry wastewater treatment is an important part involved in the urban water environment treatment and the sponge city construction, but the selection of treatment mode lacks strong theoretical support. The centralized and decentralized modes of balcony laundry wastewater in western countries, as well as three modes in China, including rainwater and sewage diversion, terminal interception and recycling, and also the relevant advantages, disadvantages and application conditions are analyzed. Meanwhile, the possible adverse impact of extensive rainwater and sewage diversion reconstruction on the sewage treatment plant in southwest downtown Suqian is evaluated, and three practical scenarios are put forward, especially in combination with sponge city construction for simultaneously solving the problems of waterlogging and water environment pollution, which has important value for similar urban balcony laundry wastewater treatment.
