摘要
介绍了广州市城市河涌的污染原因及生态恢复历程,总结了城市河涌生态恢复的实践经验:首先对城市河涌实施污水截流,对河涌淤泥进行清疏与处理;城市排水系统雨污分流是一个渐进过程,雨季时应尽量减少合流污水进入城市河涌;循环补水与综合整治是提高城市水环境的有效方法。
The pollution reasons and ecological restoration course of urban rivers in Guangzhou City are introduced. The practice experience in ecological restoration of urban rivers is summarized. The sewage should be intercepted along urban rivers. The sediments in rivers should be dredged and treated properly. The separation of rainwater and sewage in the urban drainage system is a gradual process. The combined sewage flowing directly into urban rivers should be reduced in rainy season. The circulating wa ter replenishment and comprehensive improvement are effective methods to improve urban water environ ment.
