摘　　要：考察了聚丙烯酰胺(PAM)、壳聚糖(CTS)、硅藻土以及复合絮凝剂对剩余污泥的调理作用,实验结果表明它们都有助于改善活性污泥的脱水。通过比较污泥比阻的变化,观察试验中的矾花生成现象及滤液情况,可知单体CTS,PAM及硅藻土/PAM,硅藻土/壳聚糖无机与有机复合调理对剩余污泥的调理效果相似。再根据张印堂,Asano等国内外学者对PAM和CTS的研究,理论上CTS可以取代PAM。investigated the polyacrylamide （ PAM）, chitosan （ CTS）, Diatomite, and its composite flocculant conditioning to the residual sludge. The experimental results show that they all help to improve the dewatering of activated sludge. To observe the trial of alum to generate phenomenon and the filtrate, comparing the change in sludge specific resistance monomer chitosan, PAM and diatomite/PAM, diatomite/CTS inorganic and organic compound conditioning on the remaining the sludge conditioning effect was not bad up and down. According to research of ZHANG Yin - tang, Asano, etc. to PAM and the CTS, the chitosan can replace PAM theoretically.
