Analysis on Urban River Water Replenishment Plan Selection Choice of City River Water Replenishment Plan——Taking the City River of Taijiang District in Fuzhou as an Example

福州市台江区打铁港、达道河和瀛洲河,河水动力交换条件差,且三条河两岸皆是建成区,排放的污水长期在河道内回荡,厌氧发臭,水体污染严重。根据实际情况,采用截污及生态补水方式进行处理,使其水质达到不黑不臭标准。从三条内河现状、存在问题以及现状河道水质进行详细分析,并通过补水水源点的选择及对应的水质、方案优缺点、工程经济技术等方面进行论证,确定补水水源点的选择,为类似城市进行内河整治提供了相关参考。

The dynamic switching condition of Da tie gang,Da dao river and Ying zhou river in Taijiang District of Fuzhou are poor.Moreover, both sides of the three rivers are the built-up area, whose discharge of sewage pouring into the river causes the water of therivers smelly and serious water pollution.

After a detailed analysis of the problems and the water quality of the threerivers, we made the demonstration of water quality, the corresponding point of replenishment of water solution, the advantages and disadvantagesof the plans, and the economic engineering technology etc. to determine the choice of the water supply point, which provides areference for other cities to carry out river regulation.
