摘要

采用磁混凝技术处理中纤板废水。研究了磁粉、混凝剂和助凝剂的种类及其比率的影响。试验结果表明,使用A磁粉的磁混凝技术处理中纤板废水,化学耗氧量（COD）去除率最高可达88.03%,较单纯采用混凝技术COD去除率提高了52.25%;悬浮物（SS）去除率达98.91%,提高了约4%;色度去除率达98.01%,提高约3%。

Abstract

Wastewater from medium density fiberboard production was treated using magnetic coagulation technology with aluminium polychloride,polyacrylamide,and magnetic particles.The chemical oxygen demand（COD） removal efficiency of the magnetic coagulation method reached to 88.03%,which was improved by about 52.25% when compared to a sole coagulation technology.The suspended solid removal rate was 98.91%,which was about a 4% improvement.The color removal rate was 98.01%,which was improved by 3%.
