摘要
随着污水治理技术的进步,点源水污染在得到较好控制的同时,面源水污染的问题越来越突出,特别是合流制地区的雨季溢流污染问题,已成为进一步提升城市水环境质量的主要障碍。鉴于溢流污染治理工程的特殊性,科学合理地确定工程效果评价方法至关重要。结合广州市的相关研究成果,介绍溢流污染治理工程最主要的评价指标——溢流污染削减率的评估方法和思路,为其他城市开展相关工作提供参考。
Along with the progress of the sewage treatment technology, the point source water pollution is better controlled, but at the same time, the problem of non-point source water pollution becomes more and more prominent, especially the rainy overflow pollution in the combined sewer region, has become the main obstacle further to improve the urban water environment. In view of the particularity of overflow pollution treatment engineering, it is very important to scientifically and reasonably determine the evaluation method of engineering effect. Combined with the relative study results of Guangzhou, the article introduces the evaluating method and idea of the main evaluating indexes – pollution reduction rate of the overflow pollution treatment engineering, which can be referenced for carrying out the relative works in the other cities.
