Abstract:With the increasing demands of China on environmental protection emissions and water resources conservation, the treatment and reuse of desulfurization waste water in coalfired power plant are gradually becoming the hot spots of power industry. Through analyzing the characteristics of desulfurization waste water in coalfired power plant, which is generated by limestonegypsum wet flue gas desulphurization, and combining with the utilization situations of water resources of different industries, this paper proposes a comprehensive utilization scheme of desulfurization waste water, which is supplied to the manufacturing enterprise of ecofriendly bricks. The scheme could not only save water resources and realize the comprehensive utilization of desulfurization waste water in coalfired power plant, but also decrease operating cost of enterprise and obtain good economic benefits. 
