- 摘要:
- 在消除水体黑臭的过程中，合流制溢流(CSO)污染不容忽视。如何实现溢流频次大幅度减少和削减入河污染量，是CSO污染控制的关键。详尽分析黑臭水体的现状问题和成因，制定合理的CSO控制目标和技术路线，比选多目标多阶段下的工程措施，才能给出切实可行的治理方案。以重度黑臭水体浯溪为例，梳理国内外CSO污染控制有效做法，根据浯溪特点和问题成因，以治理目标和技术思路为指引，统筹末端出口截流、调蓄池建设、污水处理和生态设施等工程，经模型优化比选得出最佳实施方案。结合合流改造工程开展动态评估，制定近远期工程措施，实现浯溪CSO污染得以有效控制和消除黑臭长制久清。
- 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.
