合肥市环城水体的生态补水研究

Study of Ecological Water Compensation to Water Bodies Around Hefei City

合肥市的环城水体没有天然补给水源,极易引起水体污染,开展生态补水工程很有必要。由于水资源紧缺,拟采用中水补水。选用一维河道稳态水质模型及均匀混合水质模型研究了不同量的生态补水对银河、包河、雨花塘水体影响,以及流动后对南淝河亳州路桥-长江路桥段的影响,评估了生态补水工程的可行性,最终确定了最佳的生态补水量。

It is necessary that the project of ecological water compensation r is developed in Heifei because water system of Hefei is polluted. According to the fluvial hydrology in the park around the city term data, the difference analyzes to the sections a proceeding present condition in each river, finding out the main pollutant. In order to improve the water quality and beautify the city environment, the government of Hefei adopts the program of using the regenerative water. In the light of this, this paper models the water of the park around the city and Nanfei river by using one dimension equable state quality model and even mix water quality model. Based on this, this paper calculates the effect of varies amount of the regenerative water respectively, and assess the feasibility of the program of the using the regenerative water. In the end, this paper ascertains the best amount of the regenerative water.
