摘要
本文通过制备一种聚合氯化铁-壳聚糖(PFC-CTS)新型复合絮凝剂,并采用三步污泥调理法强化污泥脱水效率。实验结果表明,m(PFC):m(CTS)=1:2,PFC-CTS投加量为40mg/L时絮凝效果最佳,为污泥高效减量化处理提供了理论依据。
A new type of compound flocculant PFC CTS was prepared and the dehydration efficiency of sludge was enhanced by three-step sludge conditioning. The experimental results show that the flocculation effect is the best when the dosage of M(PFC): m(CTS) =1:2 and the dosage of PFC CTS is 40 mg/l. The three-step sludge conditioning method proposed in this study provides theoretical basis for sludge reduction treatment.
