以污泥脱水性能与沉降性能为指标,研究了超声波调理联合PAM对污泥脱水性能的影响。实验结果表明,单独使用超声波调理的最佳调理时间为20 s,此时污泥比阻为0.68×109 s2/g;采用PAM对污泥进行调理时,在浓度为0.1%,投加量为100 mg/L时污泥比阻最小,为0.32×109 s2/g;采用超声波与PAM联合调理时,利用正交试验得到最适合的组合条件为:调理时间20 s、PAM投加量100 mg/L、浓度0.15%。
以汙泥脫水性能與沉降性能為指標,研究瞭超聲波調理聯閤PAM對汙泥脫水性能的影響。實驗結果錶明,單獨使用超聲波調理的最佳調理時間為20 s,此時汙泥比阻為0.68×109 s2/g;採用PAM對汙泥進行調理時,在濃度為0.1%,投加量為100 mg/L時汙泥比阻最小,為0.32×109 s2/g;採用超聲波與PAM聯閤調理時,利用正交試驗得到最適閤的組閤條件為:調理時間20 s、PAM投加量100 mg/L、濃度0.15%。

Through measuring the sludge dewatering and settling performance,the effect of Ultrasonic and PAM on sludge dewatering process was studied. Ultrasonic treatment time,dosage of PAM,and concentration of PAM were changed and tested. The orthogonal test revealed that,at ultrasonic treat-ment time of 20 s,dosage of PAM of 100 mg/L,concentration of PAM of 0. 15%,the best sludge dewatering performance could be obtained.
