摘　　要：丙烯腈/腈纶污水污染物浓度高,含难生化处理的低聚物,处理难度大,成为困扰企业污水达标排放的难题。介绍了国内企业腈纶污水处理的工程实践及实验研究,采用PACT/WAR工艺处理腈纶污水的工程实例。工程运行表明:该工艺处理包括丙烯腈/腈纶污水在内的炼油、化工污水,处理效果良好,能够达到一级直排标准。针对运行中出现的问题,提出相应的解决方案及优化建议。Acrylonitrile/acrylic fiber wastewater has a high concentration of pollutants and contains oligomers that are difficult to be treated biochemically and has become a problem for enterprises to discharge wastewater up to standard.This paper introduces the engineering practice and experimental research of acrylic fiber wastewater treatment in domestic enterprises and the engineering practice of treating acrylic fiber wastewa-ter by PACT/WAR process. The engineering operation shows that the treatment effect of this process is good for oil refining and chemical wastewater including ac-rylonitrile/acrylic fiber wastewater. It can achieve the first level of direct discharge standard. Aiming at the problems in operation, the corresponding solutions and optimization suggestions are put forward.
