摘　　要：详细分析了水电站污水排放对自然环境水土和鱼资源各方面影响,包括高温冲击、化学物理性质变异以及造成水体富营养化等;通过引入区域影响率和死亡率指标,建立了水电站污水排放对自然水体和鱼资源的影响分析模型,测算出污水排放对自然水体的总体影响率和自然水体中下一组年龄鱼群数目两项参数,实现对水电站污水排放对自然水体鱼资源影响的综合测评;针对水电站污水排放对自然水体造成的影响,提出了水体净化方式即:生物法治理和自然水体氮磷去除。The effects of sewage discharge from hydropower stations on various aspects of water, soil and fish resources in thenatural environment, including high temperature impact, chemical and physical properties, and eutrophication of water bodies,were analyzed in detail. Hydropower station sewage discharge was established by introducing regional influence rate and mortalityindicators. An analysis model for the impact of water and fish resources, measuring the overall impact rate of sewage discharge onnatural water bodies and the number of age groups of fish in the natural water body, to achieve a comprehensive assessment of theimpact of sewage discharge on natural fish body resources, Aiming at the impact of sewage discharge on the natural water body,the water purification method is proposed： biological treatment and natural water nitrogen and phosphorus removal.
