摘　　要：以自制星形高分子絮凝剂star-PDA为絮凝剂,城市剩余活性污泥为应用对象,探讨了影响自制高分子絮凝剂star-PDA脱水效果的因素—p H、温度、絮凝剂溶液放置时间。结果表明p H=7中性条件下,温度为40℃,絮凝剂溶液放置时间为5 h时,絮凝沉降效果最好。研究比较了直线型PDA与自制星形产品(star-PDA)的污泥脱水效果,可以看出星形结构的PDA具有很大的优势。With homemade star polymer flocculant star-PDA as the flocculant, the residual activated sludge of city as application object, the influence of homemade high polymer flocculant PDA dehydration effect factors--pH, temperature and the flocculant solution set time are discussed. The results showed that pH =7, temperature 40 ℃, the flocculant solution are placed for 5 h, flocculating settling effect is best. The linear PDA with homemade star products （star-PDA） sludge dewatering effect is compared. It can be seen that PDA in a star structure has a great advantage.
