PAC和PAM絮凝剂处理PTA工业废水的应用研究

Study on the application of PAC and PAM flocculant in the treatment of PTA industrial wastewater

考察了PAC和PAM絮凝剂对PTA废水的处理效果,分析了絮凝剂PAC和絮凝剂PAM投加量对出水浊度的影响。研究结果表明,PAC投加浓度为4～6 mg/L,PAM投加浓度为0.6～0.8 mg/L时,对应出水浊度<2 NTU,去除率>55%。

The effectiveness of PAC and PAM composite coagulants in PTA wastewater were investigated, and theeffect of the addition of PAC and PAM on the turbidity was analyzed.The resuhs showed that the best dosage of PAC was 4-6mg/L, and the dosage of PAM was 0.6-0.8 mg/L, and the turbidity decreased to the 2 NTU.
