大型水电站施工期污水截排工程设计研究

Design of Sewage Interception in Construction Stage of Large Hydropower Station

对大型水电站施工期污水截排工程进行设计能够降低污水排放量,对环境保护具有重要意义,针对当前大型水电站施工期污水截排工程存在的截排效果与工程投入成本之间矛盾的问题,提出一种基于污水截排流量的大型水电站施工期污水截排工程设计方法,首先对大型水电站施工期污水的来源进行分析,确定污水中主要污染物,然后对大型水电站施工期污水截排工程的设计任务进行分析。实现结果表明,所提方法设计的污水截排工程能够实现截排效果与工程投入成本之间的有机统一,在降低工程投入的同时保证截排效果。

It is of great significance for the environmental protection to design the sewage interception project in the construc-tion period of the large hydropo -wer station. , determines the main pollutants in the sewage, and then designs the sewage intercep-tion project in the construction period of the large hydropo-wer station. At the same time,Reduce the cost of the project,on thisbasis,through the selection of water quality model to achieve large - scale hydropower station construction period sewage intercep-tion engineering design. The results showthat the proposed method can achieve the organic unity between the cutting effect andthe project input cost, and reduce the project investment while ensuring the effect of cutting.
