重庆市花溪河流域污染成因分析及综合治理措施

Source Analysis and Comprehensive Treatment of Water Pollution in Huaxi Watershed,Chongqing

随着社会经济的发展,环境污染问题特别是流域水体污染尤为突出。通过实地踏勘、查阅文献等方式,分析花溪河水体污染原因。结果表明,城镇生活污水为主要污染源,其次为工业点源污染,农业面源及其他污染源所占比例相对较小。结合流域实际情况,提出加强监管、合理规划、建立人工湿地、利用美人蕉浮床净化污水等措施改善花溪河污染状况,为次级河流的环境保护提供参考。

With the development of social economy,the problem of environmental pollution,particularly that of water pollution,is especially evident.In this paper,the source of water pollution in Huaxi Watershed,Chongqing is analyzed based on survey and literature.The results show that domestic wastewater ranks first followed by the industrial point pollution,while agricultural non-point source and other sources have small percentages.In consideration of the watershed＇s characteristics,a series of countermeasures for comprehensive treatment are put forward to reduce the pollution,such as strengthened supervision,appropriate planning,creation of artificial wetland,and adoption of canna floating bed technology.This paper provides some ideas for environmental protection of branch rivers.
