摘要
以重庆城市垃圾填埋场的垃圾渗滤液为研究对象 ,采用Fenton法进行催化氧化后 ,再投加聚合铁进行混凝沉淀处理 ,可较大幅度地降低废水中的CODCr,为后续的生化处理提供条件。研究了原水 pH值、FeSO4·7H2 O和H2 O2 的投加量。
In this paper, treatment of the landfill leachate from Chongqing landfill was studied by a two-stage process of oxidation with Fenton′s reagent and then coagulation with polyferric sulfate. After this process,COD Cr of landfill leachate dropped from 25 733mg/L to 8 518mg/L,and was prepared for the next biological treatment process.Through this test, the best condition of Fenton′s reagent and coagulation with polyferric sulfate was achieved with FeSO 4·7H 2O, H 2O 2/FeSO 4·7H 2O and polyferric sulfate dosage of 0 4%,2 92,0 2% respectively.The effect of pH value,dosage of FeSO 4·7H 2O and H 2O 2,reaction time and dosage of polyferric sulfate on COD Cr removal efficiency was studied.
