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Fent on 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、FeSO4·7H2O 和H2O2 的投加量、反应时间 及聚合铁的投加量对CODCr去除率的影响。
Abstract:
In this paper , treatment of the landfill leachate f rom Chongqing landfill was studied by a two -stage process of oxidation with Fenton′s reagent and then coagulation w ith poly ferric sulfate .Af ter this process, CODCr of landfill leachate dropped from 25 733 mg/L to 8 518 mg/ L , and w as prepared for the next biological treatment process .Through this test , the best condition of Fenton′s reagent and coagulation w ith polyferric sulfate was achieved wi th FeSO4·7H2O , H2O2/FeSO4·7H2O and polyferric sulfate dosage of 0.4 %, 2.92 , 0.2 % respectively .The effect of pH value , dosage of FeSO4·7H2O and H2O2 , reaction time and dosage of polyferric sulfate on CODCr removal efficiency was studied .
