摘要
调查了三峡库区重庆段沿岸城市已建成并投入使用的17个污水处理厂,结果表明:库区污水处理厂处理污水效果较好,只有少数脱氮、除磷效果不佳;由于收集污水管网建设滞后,库区水环境存在较大隐患;进水负荷超过设计能力范围时,处理效果明显降低。
In order to alleviate the water pollution loads,there had constructed some sewage treatment works along the Three Gorges Reservoir. For the sake of recognizing the present conditions of these works,we had investigated and analyzed present condition and problem in 17 sewage treatment works in some towns. It was suggested that these works were good for circulation generally,but there was bad effect of de-nitrification and de-phosphorization in few ones. There were big menaces for the water environment of reservoir,because the construction of pipe networks were late;the disposal effect had debased markedly if the in-load were higher than design.
