摘要
在紫外光照下,利用H2O2和草酸铁络合物对垃圾渗滤液进行了处理,探讨了紫外光照时间、pH值、fenton试剂、草酸铵对垃圾渗滤液中CODCr去除率的影响。结果表明UV-vis/草酸铁络合物/H2O2法对垃圾渗滤液CODCr去除率有较好的效果,当操作条件是pH取3,反应时间为1h,H2O2投加量为1.4mL,H2O2/FeSO4.7H2O投加比(摩尔比)为5∶1,草酸铵投加量为5.5mL时,CODCr的去除率达到了78.8%。
The photodegradation of landfill leachate by H2O2 - ferrioxalate complexes as a photo - oxidant under UV light source is studied. The effect of PH, fenton reagent, ammonium oxalate and reaction time on the removal rate of CODCr is discussed. The results show that removing CODCr in landfill leachate by fenton oxidation is very effective and rapid; the removal rate of CODCr is 78.8% when the operation condition is as follows： with pH 3, the reaction time 1 hour, the dosage of H2O2 1.4mL, the ratio of H202 and FeSO4·7H2O 5：1 and the dosage of ammonium oxalate 5.5 mL.
