Abstract:

The effect of the combination process,high dense settling pond+V-type filter+resin softening+HERO,for treating the wastewater from coal chemical industry,its design parameters,and operation debugging status are introduced. The designed water treatment capacity of this project is 500 m³/h,mainly removing SS,hardness and COD from water. The operation results show that HERO process has advantages,including high recovery rate,and stable effluent water quality. It can meet the water quality requirements for the make-up water of industrial circulating cooling water.

Key words: wastewater from coal chemical industry, circulating cooling water, highly efficient RO, recovery

摘要：

介绍了高密度澄清池+V型滤池+树脂软化+高效反渗透组合工艺处理某煤化工废水的效果、设计参数及调试运行情况。该工程设计处理水量为500 m³/h，主要去除水中的SS、硬度、COD。运行结果表明，高效反渗透（HERO）工艺具有回收率高、出水水质稳定的优点，其出水可满足工业循环冷却水补水水质的要求。
