Fenton法处理垃圾渗滤液

Treatment of Landfill Leachate by Fenton Process

介绍了Fenton法处理垃圾渗滤液的中型试验 ,其中Fenton氧化在连续搅拌反应器(CSTR)中进行。试验表明 ,当双氧水与亚铁盐的总投加比一定 (H2 O2 /Fe2 +=3.0 )时 ,COD的去除率随双氧水投加量的增加而增加 ,但与双氧水在两个氧化槽的投加比例无关。当双氧水的总投加量为 0 .1mol/L时 ,COD的去除率可达 6 7.5% 。

Treatment of landfill leachate in pilot-scale by Fenton process was tested, in which oxidation process was carried out in continuous stirred tank reactor. The test results show that with a fixed molar ratio of hydrogen peroxide to ferrous ion of 3.0, COD removal efficiency increases with the increase of hydrogen peroxide dosage, but is independent of the proportion of hydrogen peroxide dosage to two oxidation tanks. When total dosage of hydrogen peroxide is 0.1 mol/L, COD removal efficiency is 67.5%. The result may be used in treatment of later period leachate from other landfills.
