摘要
采用纳滤法处理电厂离子交换树脂再生废水,试验结果表明:废水中绝大部分有机污染物的分子量小于1000,且含有的大量Cl^-;以出水的TOC浓度来评价纳滤试验的处理效果比CODcr值更合理,采用纳滤法处理废水,出水的TOC浓度将稳定在14—18mg/L范围内,达到废水的处理要求.
In this research, a nanofiltration process for the treatment of the regenerative wastewater of ion-exchanged resin from electric power plant is developed. The results show that the molecular weight of most organic pollutants is less than 1 000, and concentration of Cl^- is high in the wastewater, so TOC value is more reasonable than CODcr value to assess the treatment effect, the TOC concentration of effluent in the nanofihration process is between 14 mg/L and 18 mg/L, and the effluent could be drained directly.
