[摘 要]环保部《排污许可证管理暂行规定》中规定，2017年7月1日起火电厂必须持证排污。对
某大型发电集团公司下属火电厂调研情况表明，部分火电厂废水排放不满足排污许可制度
的要求。对此，本文提出了火电厂节水与废水治理技术路线制定应在水务查定的基础上进
行，分为管理节水、废水回用、完善监测和高盐废水治理等阶段；此外，根据2个电厂的
改造实例对节水及废水治理关键因素进行了分析，给出了示例火电厂节水及废水治理技术
路线，并对路线的制定提出了相关建议。

Abstract: The Provisional Regulations on the Management of Emission Permits issued by the Ministry of Environmental Protection stipulates that the power plants must get a permit of discharging pollutants from July 1st, 2017. According the investigation of a thermal power plant subordinate to a large-scale power generation group company, the wastewater discharge of some power plants don ’t meet the requirements of the discharge permit system. To solve the existing problems, the study proposes the fundamental principle of formulating the technical route for water conservation and wastewater treatment in thermal power plants. The technical route should carry out on the basis of the assessment of water usage, and be divided into the administration of water conservation, wastewater reuse, monitoring system improvement and high-salt wastewater treatment. In addition, the key factors of water conservation and wastewater treatment are discussed according to the transformation examples of two power plants. Finally, the technical route for water conservation and wastewater treatment in an example thermal power plant is given, and related suggestions for the formulation of the route are put forward.
Key words: pollutant discharge permit system, water conservation, wastewater treatment, assessment of water usage, administration of water conservation, high-salt wastewater
按照环保部《排污许可证管理暂行规定》（环水
体【2016】186号）[1]的要求，2017年7月1日起
火电企业必须持证排污。经调研，燃煤电厂通过近
三年密集的超低排放改造，其大气污染基本达到了
排污许可证的要求，但废水排放却存在较严重的问
题，实际排放情况与排污许可证的要求有一定差距。火电厂必须实施全厂性节水改造来减少废水排放量，同时进行废水排放综合治理，确保废水经处理后全部回用或达标排放，必要时对高盐废水进行固化处理，形成无害固废，满足排污许可证要求。 本文在对大型发电集团公司火力发电厂水资源综合利用情况调研的基础上，对不同区域、不同万方数据
