PAC处理垃圾渗滤浓缩液中PAM投加量影响研究

Study on the Effect of PAM Dosage on PAC Treatment of Landfill Leachate Concentrate

摘要: 本文采用PAC + PAM混凝沉淀处理垃圾渗滤液浓缩液。研究了不同PAM投加量下，对沉降性、COD与TP去除率的影响，为后续工艺正常进行提供保障。研究结果表明，PAM对TP去除率影响不大，在PAC投加量为1.5 g/L时，PAM投加量为10~15 mg/L时，沉降性与COD去除率较好。

Abstract: Landfill leachate concentrate was treated by PAC + PAM coagulation-sedimentation. The effects of different PAM dosages on sedimentation, COD and TP removal rates were studied to provide guarantee for the normal operation of subsequent processes. The results showed that PAM had little effect on the TP removal rate. When the dosage of PAC was 1.5 g/L and the dosage of PAM was 10~15 mg/L, the sedimentation and COD removal rate were better.
