An Experiment on Enhanced Coagulation-Flocculation and Biodegration for Disposal Slight-Polluted Water

该文为高锰酸钾预氧化强化混凝与亲水性悬浮填料处理微污染原水的实验研究.当原水CODMn为6.11 mg/L,浊度为10.74 NTU,UV254为0.158,NH3-N为1.33 mg/L时,投加高锰酸钾1 mg/L,聚合硫酸铁(PFS)40 mg/L,聚丙烯酰胺(PAM)-0.1 mg/L,生物反应柱停留时间60 m in,出水相应水质参数值分别为2.47 mg/L、3.95 NTU、0.121、0.55,去除率分别为59.5%、63.25%、23.40%、58.60%.

This paper is a stage report of an experiment on potassium permanganate and suspending plastic filler disposal technique . When raw water CODMn is 6. 11 mg/L, turbidity 10.74 NTU , UV254 0. 158, NH3 - N 1.33 mg/L, and when inputting amount of potassium permanganate is 1mg/L, the inputting amount of the polymerism of iron sulfate 40 mg/L, the inputting amount of the PAM 0. 1 mg/L, and the waiting time in the biodegration column 60 min , the water quality parameter of filtered water will be 2.47 mg/L, 3.95 NTU, 0. 121, 0. 55 mg/L respectively, and the removal percentage will be ：59.5 %, 63.25%, 23.40%, 58.6% respectively.
