摘　　要：高含盐量的城市再生水、矿井疏干水作为电厂水源且要求废水零排放时,循环水的浓缩倍数高达8.77。本文从电厂的水量平衡、用户对水质的要求着手,设计出一套全厂综合性的水处理系统。结果表明,经过该系统的处理,循环水的碳酸盐硬度浓缩倍数可以从8.77降为3.65,硫酸根浓缩倍数从8.77降为6.10,解决了循环水的腐蚀和结垢问题,从而实现了火电厂的废水零排放。When the water source of the plant were the municipal reclaimed water of high salt and coal mine drainage, and the waste water was zero discharge required, the concentration of the cycles was up to 8.77. Basis on the water balance of the plant and the user requirements of water quality, we have designed a set of comprehensive water treatment system. The results＇ showed, the carbonate hardness concentration of the cycles reduced from 8.77 to 3.65 and the sulfate concentration of the cycles reduced from 8.77 to 6.10 after treatment, which made the waste water zero discharge be achieved and the corrosion and scaling problems were also solved.
