电芬顿-紫外一体化设备对于垃圾渗滤液处理效果研究
Study on treatment effect of landfill leachate by electro-Fenton-UV integrated equipment
采用电芬顿-紫外一体化设备处理垃圾渗滤液,在进水流量为4~5 m3/h,进水pH=3.0,析出电压=6 V(运行方式为间歇开启20 min),还原电压=8 V(持续运行),H2O2(7.5%)投加比例4%的反应条件下,针对蒸发产水、混合产水、DTRO产水分别可以达到60%、71%、78%的COD去除效果,并且电芬顿耦合紫外催化的组合工艺可以显著提升COD的去除效果,对比传统芬顿工艺,电芬顿在运行成本上可以节约15%~20%,具有较好的应用优势。
Electro-Fenton-UV integrated equipment is employed to deal with landfill leachate.COD removal efficiencies can reach 60%,71% and 78%,respectively for evaporation water production,mixed water production,and DTRO water production under the reaction conditions that water inlet flow is 4-5 m3/h,pH=3.0,the precipitation voltage is 6 V (intermittently turning on for 20 min),the reduction voltage is 8 V (running continuously),and the dosage of 7.5% H2O2 is 4%.Electro-Fenton coupling with UV catalysis process can significantly improve the removal effect of COD.Compared with the traditional Fenton process,electro-Fenton process can save 15%-20% in terms of operating cost,presenting a good application advantage.
