对云南威信煤电一体化一期电厂进行最严格水资源管理制度的三条红线控制指标定量分析和计算，选取项目用水总量和流域水资源利用率分析用水总量控制指标；取设计耗水率、新水利用率、取水指标、全厂复用水率、循环水利用率、厂区生活用水等来分析用水效率控制指标，选取水功能区水质达标率分析水功能区限制纳污指标。结果表明：项目建成后流域水资源开发利用率为7.4％；设计耗水率0.51～0.61 m3／（s· GW）、新水利用率100％、取水指标0．58 m3／（s· GW）、全厂复用水率98.3％、循环水利用率98.7％；项目要求电厂所有退水必须全部回收利用，污水零排放，所在区域水质目标为Ⅱ类。
對雲南威信煤電一體化一期電廠進行最嚴格水資源管理製度的三條紅線控製指標定量分析和計算，選取項目用水總量和流域水資源利用率分析用水總量控製指標；取設計耗水率、新水利用率、取水指標、全廠複用水率、循環水利用率、廠區生活用水等來分析用水效率控製指標，選取水功能區水質達標率分析水功能區限製納汙指標。結果錶明：項目建成後流域水資源開髮利用率為7.4％；設計耗水率0.51～0.61 m3／（s· GW）、新水利用率100％、取水指標0．58 m3／（s· GW）、全廠複用水率98.3％、循環水利用率98.7％；項目要求電廠所有退水必鬚全部迴收利用，汙水零排放，所在區域水質目標為Ⅱ類。

Quantitative analysis of the control index“Three Red Lines”in the strictest water resources management system in Weixin coal electricity integration power plant in Yunnan Province were made, selecting the total water consumption of project and utilization rate of river basin water resources to analyze the water consumption control index, selecting the designed water consumption rate, new water utilization rate, water intaking indicators, whole plant water reuse rate, water cycle utilization rate, domestic water of plant, etc.to analyze the water consumption quota index, selecting the water quality compliance rate of water function area to analyze the pollutant carrying capacity index.The results show that the water resource exploitation and utilization rate of the basin is 7.4%after the completion of the project;as for the water use efficiency index, the designed water consumption rate is 0.51 ~0.61m3/(s.GW), new water utilization rate is 100%, water intaking indicator is 0.58m3/(s.GW), whole plant water reuse rate is 98.3%, water cycle utilization rate is 98.7%;the project requires all the returning water in the power plant be recycled, with sewage zero discharged and regional water quality reaching class II.
