分床精处理阳树脂再生用水量高原因分析与处理

Analysis and treatment on cation resin regenerated water of cation-anion separated bed polishing

针对某厂空冷机组阳阴分床精处理阳树脂再生耗用除盐水量大的问题进行分析,发现主要原因是再生擦洗程序设置不合理、树脂擦洗水位控制不好、阳树脂机械截留导致的污染。进行了擦洗程序优化,增加了空气擦洗次数;进行了设备改造,加装了倒U型排水管。解决了阳树脂再生耗用除盐水量大的问题,具有一定的经济效益和环保效益。

The reason that the seperated beds in an air cooling power plant consume too much of demineralized water in regeneration is analyzed. It is found that the regeneration scrub program set unreasonable, scrub resin level control is not good, positive resin mechanical entrapment pollution caused due to high water consumption cation resin mainly scrub and scrub procedures were optimized and equipment modification, cation exchange resin regeneration solution to the problem of large consumption of brine in addition, produce economic and envi- ronmental benefits.
