| 摘 要： | 采用混凝过滤工艺对PVC乳化废水进行了预处理试验,研究了混凝剂种类、pH值、混凝剂投加量及絮凝剂投加量对处理效率的影响。试验结果表明:混凝剂Al2(SO4)3·18H2O投加量100mg/L,PAM投加量3mg/L和废水pH值为5.5的条件下,进水ρ(CODCr)为12000mg/L,经混凝沉淀+石英砂过滤后,出水ρ(CODCr)可降至750mg/L。 |

Testing on Treatment of Emulsified Wastewater from PVC Production by Conventional Coagulation-Filtration Method |
|
| Abstract: | PVC emulsified wastewater was treated by a coagulation filtration process.Factors that influence the treatment efficiency,such as the kind of flocculant,the pH value and the dose of flocculant,were studied.The results show that when the concentration of the coagulant Al2(SO4)3·18H2O is 100 mg/L,the concentration of PAM is 3 mg/L,the pH value of the wastewater is 5.5 and the inlet water is of ρ(CODCr) 12 000 mg/L,the ρ(CODCr) of the effluent water can be reduced down to 750 mg/L after coagulation filtration plus quartz sand filtration. |
| Keywords: | PVC coagulatory settling aluminum sulfate quartz sand filtration wastewater treatment |
