ABR-接触氧化-化学氧化组合工艺处理垃圾渗滤液方法研究

Research on treatment about landfill leachate by ABR-biological contact oxidation and wetting catalytic oxidize

以垃圾渗滤液为研究对象,应用ABR-接触氧化-化学氧化组合工艺进行处理.通过分阶段污泥培养驯化以及变容积负荷进行试验研究,试验结果表明:进水有机负荷小于10 kg COD/(m3·d),好氧出水COD稳定在1 000～1 500 mg/L,去除率可以稳定在80%～85%;好氧池出水经过Fenton氧化处理,出水COD小于100 mg/L.该组合工艺对垃圾渗滤液能够进行有效处理,运行效果较好,技术上可行.

ABR\|contact oxidation\|wet catalysis oxidation is utilized to treat landfill leachate. The two steps performed to operate the reactor and cultivate the sludge and the changed volume loading experiment shows that the influent COD is 10 kg/(m 3·d), effluent COD is 1 000~1 500 mg/L, the removal rate may remain during 80%~85%; the effluent COD is under 100 mg/L after the effluent in oxidation pond is treated by Fenton oxidation. The result indicates that the treatment effect is well for landfill leachate by the technology.
