黄岩西江河网水环境改善方案的探讨

On Water Environment Improvement of Xijiang River Network

黄岩城区西江河网水系的河道多数深度不足,各种污水直接排入河道,造成水环境恶化.综合分析原因后认为,水环境改善应有针对性地做好污染源控制,利用水库调水冲污、河网调度、治理"断头河"等有效手段,让水体流动起来.并据此提出了改善水环境应急处理、短期改善、长期生态恢复的对策.

All kinds of sewage was diacharged directly into the river course of Xijiang river system,which caused water environmental degradation due to the insufficient depth of the river course.Comprehensive analysis is given in the paper on how to conduct an efficient control on pollution source in order to improve the water environment,such as pollutant-scouring by water transfer,river scheduling,beheaded-river management,etc,making water running.The emergency treatment is also discussed in the paper and some countermeasures are put forward to improve the ecological environment in short-term recovery,as well as in long-term measures.
