摘 要: | 研究了以聚合硫酸铁为主凝剂、两性田菁胶(ASG)为助凝剂处理城市生活废水的各种影响因素.实验结果表明:聚合硫酸铁和两性田菁胶分别以200mg/L和10mg/L的复配浓度、pH值接近7时混凝效果最佳,CODCr去除率达到近80%,处理后废水CODCr达到国家排放标准.

Flocculation Aid of Amphoteric Sesbania Gum to the Treatment of Domestic Wastewater |
| |
Abstract: | Wastewater from city was treated using primary flocculant polyferric sulfate ( PFS) and coagulant aid amphoteric sesbania gum (ASG). The results show that the flocculation effect is the best when c(PFS)=200 mg/L, c(ASG)=10 mg/L and pH=7. The reduction percentage of CODCrreaches nearly 80%,the CODCrof treated wastewater coincides with the administration standard. |
