摘要:以南京市某生活垃圾轉(zhuǎn)運(yùn)站的廚余垃圾滲濾液處理為例，介紹了預(yù)處理+厭氧+MBR（兩級(jí)A/O+超濾）+臭氧催化氧化處理工藝在廚余垃圾滲濾液處理中的應(yīng)用情況。預(yù)處理階段采用疊螺脫水機(jī)、隔油池及氣浮裝置去除滲濾液中大量的懸浮物及油脂等物質(zhì)，再通過厭氧反應(yīng)器降低滲濾液中的有機(jī)物濃度，厭氧出水進(jìn)入MBR系統(tǒng)進(jìn)一步去除有機(jī)物、氮、磷等污染物；深度處理段采用臭氧催化氧化作為保障措施。該項(xiàng)目預(yù)處理段對(duì)懸浮物、動(dòng)植物油、TP的去除率分別為92.4%、88.1%、87.9%，生化處理段對(duì)COD、NH3-N、TN的去除率分別為99.0%、97.5%、93.4%，主要出水指標(biāo)可達(dá)到《污水排入城鎮(zhèn)下水道水質(zhì)標(biāo)準(zhǔn)》（GB/T 31962—2015）中的B級(jí)限值規(guī)定。
Abstract:Taking the kitchen waste treatment in a domestic waste transfer station in Nanjing as an example, the application of a combined treatment process including pre?treatment, anaerobic, MBR (two-stage A/O and MBR) and ozone catalytic oxidation is introduced. In the pre-treatment stage, a stack dehydrator, an oil trap and an air flotation device are used to remove large amounts of SS and grease in the leachate. The anaerobic process is used to remove organic content in leachate, and then the anaerobic effluent entered MBR to further remove the pollutants such as organic matter, nitrogen and phosphorus. Finally, ozone catalytic oxidation is used as a safeguard measure in the advanced treatment process. In this project, the removal rates of suspended solids, animal and vegetable oil, and TP in pre-treatment stage are 92.4%, 88.1% and 87.9%, respectively. The removal rates of COD, NH3-N and TN in biochemical treatment section are 99.0%, 97.5% and 93.4%, respectively. The effluent quality could meet the standard of level B of Wastewater Quality Standards for Discharge to Municipal Sewers (GB/T 31962-2015)．
