摘　　要：介绍了超滤及反渗透联合处理技术用于己内酰胺装置部分废水的试验结果 ,给出了不同回收率下的出水水质 ,对处理后出水的回用提出了建议。试验结果表明 ,当回收率为 70 %时 ,处理后的硫铵冷凝水电导率平均降低 92 6 % ;如果对硫铵中和池的排放水进行一级反渗透处理后继续采用二级反渗透处理 ,其NH3 N可降低到 0 70mg/L ,COD也相应降低。二级反渗透出水水质较好 。Using Ultrafiltration (UF) and reverse osmose (RO) technology in CLP production plants can treat wastewater. The qualities of drained water can be given in different recovery yield.The experiment results showed that when the recovery yield was 70% the conductivity ofthe condensed water oftreating ammoniumsulfate decreased 92 6% on the average.If using the second RO treatment continued to treat the drained off water ofthe neutralizing pool of ammonium sulfate after the first RO treatment,NH 3N decreased to 0 70 mg/L,COD also decreased appropriately.The water can be used to make up to the midhigh pressure boilers.
