摘要
城市污水处理厂每天产生大量的污泥,为了减少最终处置的污泥体积,污泥脱水是重要的处理环节。通过对不同性质的污泥进行性质分析,并选用几种高分子混凝剂对污泥进行调理试验,通过比较试验测得的污泥比阻抗值和观察试验中的矾花生成现象,以及对比滤液中的TP、COD浓度变化,确定最佳混凝剂及其投量,从而达到改善污泥脱水性能的目的。

Abstract
Based on analysis of the characteristic of the sludge, in this paper, three kinds of sludge were selected to make coagulant experiment with three different coagulants. The specific resistance to filtration is tested. Finally,the optimum coagulant with its optimum dosage is obtained and the dewatering effect is improved.
