%X 结合某准东煤矿坑口电厂高盐废水相关系统取排水现状，对新疆准东区域燃煤电厂深度优化用水改造路线进行深入探讨，并全面分析深度优化用水对于现有辅机循环冷却水系统浓缩倍率以及末端高盐废水水量、水质的影响。结果表明：深度优化用水可显著降低辅机循环冷却水系统运行浓缩倍率，但往往会造成脱硫系统脱硫废水排放量较设计工况下有所增加。深度优化用水改造路线的确定，需结合电厂现有构筑物布置等实际情况，酌情实现锅炉补给水处理系统排水的分开收集、分别回用；需对不同的凝结水精处理系统高盐废水回用方案进行经济技术对比分析，以确定凝结水精处理系统排水改造路线；另外需开展脱硫系统氯离子浓度控制提升试验，以明确脱硫废水水质远期控制水平。<br />
Combined with the current situation of extraction and drainage of part of water treatment system of a certain Zhundong coal mine’s Keng Kou power plant, the reform route of deep optimization water use for Xinjiang Zhundong regional coal-fired power plant is discussed in depth, and the influence of deep optimization water use on concentration ratio of existing auxiliary circulating cooling water system and water quantity and quality of terminal wastewater is comprehensively analyzed. The results show that the depth optimization of water use can significantly reduce the concentration ratio of the auxiliary circulating cooling water system, but inevitably leads to an increase in the discharge of desulphurization wastewater in the desulphurization system compared with the design condition. To determine the route of deep optimization of water use transformation, it is necessary to realize separate collection and reuse of drainage of boiler supply water treatment system according to the actual situation of existing structure layout of power plant. It is necessary to make economic and technical comparative analysis of different high-salt wastewater reuse schemes of condensate treatment system to determine the drainage reform route of condensate treatment system. In addition, the chloride ion concentration control and improvement test of desulfurization system should be carried out to determine the long-term control level of desulfurization wastewater quality.
