| 摘 要： | 研究了洛阳市龙翔造纸厂的生产废水进行混凝处理时所需要的最佳混凝剂。实验结果表明：PAC作为混凝剂,PAM作为助凝剂联合处理该废水时,能够取得较好的去浊率和CODCr去除率,并且相对其他几种混凝剂经济费用更少;PAC＋PAM作为最佳混凝剂时,PAC和PAM的投加量分别为133、16.6mg/L,充分混凝沉淀20min后,去浊率可达99.7%,CODCr去除率可达46.0%,取得了较好的去除效果。

| Abstract: | In this paper, the optimal coagulant was studied through the testing on the wasterwater from Luo yang Longxiang papermaking corporation. The results indicated that better removal efficiency of turbidity and COD value were obtained when using PAC and PAM as the coagulant and coagulant aid. Further more this method was more economical compare with other coagulants. The most effect rate of removal of turbidity and COD were 99.7% and 46.0% which would be obtained when using PAC and PAM as the best coagulant, the qutity of PAC and PAM added to the wastewater was 133 and 16.6 mg/L, and the time of coagulation settlling was 20 minnutes. |
