降低软水站盐耗水耗的实践

Practice of Decreasing Salt and Water Consumption of Soft Water Station

通过对软化器进水流量、再生液浓度、进盐操作、正洗反洗操作的研究，发现软化器的周期软水产量在进水流量范围90～130m＾3／h之间与进水流量成正比；平均浓度为4．57％的自然溶解的盐水的浓度梯度为6．49％／m；对于同一个软化器，其余条件相同，盐浓度在4．2％～5．9％时，软化器周期软水产量与再生液浓度成正比；预正洗操作的加入，可以将软化器使用周期延长41．1％，周期软水产量上升38．9％。经过优化后，软水站盐耗下降15．8t，／月，同比下降15．7％，水耗下降6125t／月，同比下降8．1％。

Through the research on influent flow, rebirth solution concentration, salt mtake opeinut,,l, - real and back washing operation of demineralizer, the results showed that periodic output of soft water was proportional to influent flow in the range of influent flow from 90 m3/h tol30m3/h,the concentration gra- dient of salt water whose average concentration was 4.57% is 6.49%/m ,for the same softener, with the same conditions, periodic output of soft water was proportional to rebirth solution concentration in the range of salt concentration from 4.2% to 5.9% ,and addition of preventive normal washing could prolong using period by 41.1%, increase output of soft water by 38.9%. After the optimization,for soft water sta- tion, salt consumption decreased 15.8T/Month, 15.7% down compared to the last year, and water con- sumption decreased 6125T/Month,8.1% down as compared with last year.
