| 摘 要： | 本研究根据二沉池出水特点，指出了以260nm紫外光(E260)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，比较了三种无机混凝剂在不同pH值条件下对城市二沉池出水的COD去除效果。并确定了最佳混凝剂为三氯化铁(FC)及混凝条件：pH4．5，投药量32mg(Fe^3 )／1。

| Abstract: | Based on the characteristics of effluent from secondary municipal wastewater treatment plant, it was pointed out in the paper that using light absorbance at wavelength 260nm (E260) as indicator was feasible to reflect the water quality. The correlation between E260 and COD was determined as E260=0.008COD+0.083. With E260 as indicator, coagulation using three coagulants to treat the effluent from municipal secondary wastewater was operated. It was shown that Ferrite Chloride was the best coagulant, and pH=4.5 and dosage as 32 mg/l was measured as its optimal operation conditions. |
