电厂温排水热污染防治对策初探

火、核电厂排放的循环冷却水是工业温排水中最大的热排放源。论述了火、核电厂温排水向其受纳环境水域释放的巨大热量，以及热排放对环境水域水体的理化性质及生态系统的热影响；提出采用热泵等高技术手段回收回用此余热使污源减排是治理受纳水域水生态环境，修复水域环境热容量最根本、最有效的措施；同时建议修订我国水质标准（规范）中对水温的规定，以切实加强水域热排放的有效管理。在新世纪和谐电力建设进程中，电厂循环冷却水余热高效利用不仅有明显的环境保护意义，而且在电厂节能提效，实现温排水资源化中也将有重大的经济和社会效益。

DISCUSSIONS ON PREVENTING AND CONTROLLING COUNTERMEASURES AGAINST THE THERMAL POLLUTION OF WARM WATER DISCHARGED FROM POWER PLANT

The circulating cooling water of the fossil fuel/nuclear power plant is the largest source of thermal discharge in industries. The paper described the large quantity of residual heat contained in thermal discharge, which may induce thermal pollution in the physical and chemical properties of water, as well as the aquatic ecosystem. The heat pumping technology and other high-tech means are introduced for recycling waste heat to reduce this pollution source and rehabilitate the heat capacity of water environment. This paper also proposed to revise the temperature clause of water quality standard in order to strengthen effective management of the warm water discharged. For harmonious electric construction in the new century, the highly effective utilization of the residual heat contained in warm water discharged from power plant not only has the obvious significance for environmental protection, but also has the significant economy and social efficiency in saving energy and recovering resources of the warm water discharged.
