汉江中下游水污染防治湿地系统研究
Study on Wetland System of Water Pollution Control in Middle and Lower Reaches of the Hanjiang River
【摘要】 汉江中下游地区人口众多、城市密集、工农业发达,是湖北省经济精华所在,同时也是污水大量排放环境污染比较严重的地带,随着南水北调中线工程的实施,汉江水量减少,流速减缓,水污染将更趋严重。通过分析提出,充分利用本地区湿地资源条件,并结合人工湿地,建立一套以农田为中心的,包括人工建造湿地、多级水塘、田间沟渠坑塘或基塘系统、湖滨湿地和河岸植被缓冲带等多种湿地在内的综合湿地系统,来达到防治水污染的目的。
【Abstract】 The area of the middle and lower reaches of the Hanjiang River is the cream region of the Hubei province with large population, concentrated cities and flourishing industry and agriculture. However, the water in this area has been polluted by wastewater. After the accomplishment of the water transfer project from the South to the North, the water discharge of the Hanjiang River will decrease, and the current velocity will reduce either, so the water pollution will become much more serious In order to protect the environment of this area, a system of multiple wetlands must be used to treat all kinds of wastewater. This system includes constructed wetlands, pools, canals and ditches of fields, dike and pond system, lakeside wetlands and riparian buffer strips, and the agriculture field is the center of this system.
