| 摘 要： | 采用硫酸铝、PAC、氯化铁和明矾四种混凝剂对城市污水处理厂出水进行除磷实验研究。实验结果表明,四种混凝剂硫酸铝、PAC、氯化铁和明矾的最佳投药量分别为40mg/L、30mg/L、50mg/L和70mg/L,最佳pH范围分别为6.92～8.08、5.92～10.07、6.92～10.07和6.92～8.08,在此最佳条件下,出水中总磷浓度分别为0.18 mg/L、0.03 mg/L、0.17 mg/L和0.19 mg/L,相应的去除率分别为80.85%、96.81%、81.73%和79.73%。处理后出水总磷浓度达到地表水环境质量标准(GB3838-2002)Ⅲ类水质标准(总磷浓度≤0.2mg/L)。

| Abstract: | Flocculants such as Al2(SO4)3, PAC, FeCl3 and alum are used to treat effluent from municipal wastewater plant to remove phosphorus and meet Class III of surface water standard of 0.2mg/L. Results showed that total phosphorus concentration in effluent was 0.18mg/L, 0.03mg/L, 0.17mg/L and 0.19mg/L respectively and corresponding removal efficiency was 80.85%, 96.81%, 81.73% and 79.73% after coagulating sedimentation by Al2(SO4)3, PAC, FeCl3 and alum at the optimum coagulant dosage of 40mg/L, 30mg/L, 50mg/L and 70mg/L and optimum pH range of 6.92~8.08, 5.92~10.07, 6.92~10.07 and 6.92~8.08. |
