Abstract:

Double-flow weak acid treatment process has been used for improving the concentration ratio and reducing the discharge capacity of the circulating water for the circulating water supply at Hemei Thermal Power Plant. Furthermore,using classified water can increase water circulation. Using different treatment methods according to the characters of industrial wastewater has realized the goal of zero discharge at Hemei Thermal Power Plant.

Key words: circulating water, cycle of concentration, double-flow weak acid treatment, zero discharge

摘要：

鹤煤热电厂采用双流弱酸处理工艺处理循环冷却水补充水提高循环水的浓缩倍率,减少循环水的排污量,同时采用分级用水提高水的循环使用。根据工业废水性质采用不同的处理方法,使鹤煤热电厂达到了废水零排放目标。
