降低软水站盐耗水耗的措施

Measures of Reducing Salt and Water Consumptions in Soft Water Station

为降低软水站系统的盐耗及水耗,对软化器进水流量,再生液浓度,再生操作、正洗反洗操作等进行了优化。软化器进水流量以110m3/h为宜;通过改进再生液注入方式及采用1.7m—1.25t的液位—投盐量,可保证再生液浓度;同时设置了预正洗并优化了反冲洗操作。改进后,软化器使用周期延长41.1%,周期软水产量增加38.9%,软水站盐耗减少15.8t/月,水耗减少6125t/月。

In order to reduce the salt and water consumptions of soft water station, we optimized operation parameters such as the influent flow of softener, regeneration solution concentration, regeneration operation and normal and back washing operation. Setting softener feed water flow as 110 m3/h was advisable. Improving the regeneration liquid injection pattern and using＂1.7 m（level）-1.25 t（salt）＂combiuation ensured the regeneration liquid concentration. At the same time, we set preventive normal washing and optimized the reverse wash operation. After the improvements, working cycle of the softener was prolonged by 41.1%, soft water output increased by 38.9% every cycle, and for soft water station salt consumotion decreased 15.8 t per month and water consumntion reduced 6 125 t her month.
