摘要
城市污水處理廠每天產(chǎn)生大量的污泥,為了減少最終處置的污泥體積,污泥脫水是重要的處理環(huán)節(jié)。通過(guò)對(duì)不同性質(zhì)的污泥進(jìn)行性質(zhì)分析,并選用幾種高分子混凝劑對(duì)污泥進(jìn)行調(diào)理試驗(yàn),通過(guò)比較試驗(yàn)測(cè)得的污泥比阻抗值和觀察試驗(yàn)中的礬花生成現(xiàn)象,以及對(duì)比濾液中的TP、COD濃度變化,確定最佳混凝劑及其投量,從而達(dá)到改善污泥脫水性能的目的。

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.
