| 摘 要： | 根据二沉池出水特点，指出了以260nm紫外光(F260)评价处理二沉池出水的理论依据，然后确定了E260与COD的关系式为：E260=0．008COD 0．083。最后以E260为评价指标，比较了3种无饥混凝剂在不同pH值条件下对城市二沉池出水的COD去除效果，确定了最佳混凝剂为三氯化铁(FC)及混凝条件：pH4．5，投药量Fe^3 为32mg/L。

| Abstract: | Based on the characteristics of the effluent from the secondary municipal wastewater treatment plant, the theoretical foundation of using light absorbance at wavelength 260nm ( E 260) as indicator is feasible to reflect the water quality. The correlation between E 260 and COD is determined as E 260=0.008 COD +0.083. With E 260 as indicator, the coagulation using three coagulants to treat the effluent from the municipal secondary wastewater is operated. The results show that the Ferrite Chloride is the best coagulant, and pH=4.5 and dosage as 32 mg/L is measured as its optimal operation conditions. |
