- Abstract:
- In the process of eliminating black and odorous water body, the pollution of combined sewer overflow(CSO) can not be ignored. How to reduce the overflow frequency and reduce the amount of pollution into the river is the key of CSO pollution control. This paper analyzes the current problems and causes in detail, formulates reasonable CSO control objectives and technical routes, compares and selects engineering measures under multi-objective and multi-stage, and gives feasible treatment scheme. Taking Wuxi River as an example, the effective methods of CSO pollution control at home and abroad are summarized. According to the characteristics and causes of Wuxi River, the treatment objectives and technical ideas are taken as the guidance. With the coordination of outlet interception, the construction of storage tank, sewage treatment and ecological facilities engineering, the best implementation scheme is obtained through model optimization and selection. Combined with the confluence reconstruction project, the dynamic evaluation was carried out, and the short-term and long-term engineering measures were formulated to effectively control and eliminate the black-odor and long-term pollution.
