摘要
介绍了絮凝处理技术,对不同组份废弃泥浆处理时的最佳絮凝剂种类及最佳投加量进行了研究,得出了有机絮凝剂聚丙烯酰胺较聚合氯化铝(PAC)、硫酸铝(Al2(SO4)3)有较大优势;对于密度为1.10 g/cm3、漏斗黏度为18 s的泥浆样本c,聚丙烯酰胺的最佳投加量为300 mg/L;工程废弃泥浆经过自然沉淀和离心分离后,絮凝剂的最佳投加量随泥浆密度的增加而增加等结论。
Flocculation processing technology is introduced in the research, the best flocculant type and dosage for different components of waste mud have been discussed. Conclusions such as organic polymer PAM have better treatment efficiency than polymeric aluminium and Aluminum sulfate are pointed out. The result shows that for specific gravity of 1. 10, funnel viscosity of 18s mud sample c （100ml） , the optimum dosage of polyacrylamide is 300 mg/L. The research has also came to the con- clusion that after natural precipitation and centrifugation, the best dosage of flocculant for project aban- doned mud increases with the increasing proportion of mud.
