摘　　要：造纸过程会产生大量的废水,其成分复杂,毒性大,是当前最主要的水体污染源之一,也一直是工业废水处理的难点。该文选取有代表性的助留助滤剂——阳离子聚丙烯酰胺(CPAM)驯化活性污泥,研究了活性污泥对CPAM的生物降解性,探索了活性污泥对CPAM的最佳生物降解条件,得出在最佳降解条件下CPAM的降解率为56%。Wastewater produced in the papermaking process, which has complex compositions and great toxicity, is one of the most primary pollution sources at present. Also its treatment has been the difficulty among industrial wastewater. In this study, cation polyacrylamide（CPAM）, one of representative retention and drainage study its biodegradation by acclimated activated sludge. Optimum CPAM biodegradation agents, was selected to conditions by activated sludge were explored. Degradation rate of 56% was obtained under the optimum conditions.
