为了使水电站进水口建筑物运行安全,减少进水口因污染物堵塞影响电站运行,提高发电效益,重视对水电站进水口的防污设计及研究,显得非常重要.碧口、石泉、石门三座水电站所在的白龙江、汉江干支流均属多污物河流.通过调查,这三座七十年代建成的水电站,由于对防污设计的重视程度不同,因此电站的技术经济效益就大不一样.三座水电站的防污设计及运行情况,以碧口最为理想,石泉,石门稍次之.现将有关情况简要介绍如下.
In order to ensure the safe operation of the inlet structure of the hydropower station, reduce the water inlet block due to clogging of the pollutants, affect the operation of the power station, improve the power generation efficiency, and pay attention to the design and research on the anti-fouling of the inlet of the hydropower station, it is very important that Bikou, Shiquan, The Bailongjiang and Hanjiang River where the tributaries are all belong to a number of sewage rivers .Through investigation, the hydropower stations built in the seventies of the seventies, due to the different emphasis on anti-fouling design, so the technical and economic benefits of power plants are quite different. Anti-fouling design and operation of hydropower stations to Bikou is the most ideal, Shiquan, Shihmen slightly.Therefore, the situation is briefly described below.
