摘要
研发经济安全的垃圾转运站渗滤液处理技术对确保城市垃圾收运安全具有重要意义。论文探讨了α-MnO_(2)活化过一硫酸盐(PMS)对垃圾转运站渗滤液生化池出水的深度处理效能、反应影响因素以及催化剂的可重复利用性,结果表明:α-MnO_(2)能有效活化PMS降解转运站渗滤液生化池出水中的难降解有机物,COD出水浓度满足转运站渗滤液排入污水管道国家标准(GB/T31962-2015)。α-MnO_(2)回收和重复利用潜力良好,α-MnO_(2)材料表面Mn(Ⅲ)/Mn(Ⅳ)循环转化是激活PMS产生强氧化性基团氧化难降解有机物的主要原因。
It is of great significance to develop leachate treatment technology for economic and safe waste transfer stations to ensure the safety of urban waste collection and transportation.The effect ofα-MnO_(2)activated peroxymonosulfate(PMS)on the effluent from the leachate biochemical tank of refuse transfer station,the influencing factors of the reaction and the reusability of the catalyst were discussed.The results show thatα-MnO_(2)can effectively activate the refractory organic matter in the effluent of the leachate biochemical tank of the transfer station,and the concentration of COD effluent meets the national standard for leachate discharge into sewage pipelines(GB/T 31962-2015).α-MnO_(2)has good recovery and reuse potential,and the cyclic conversion of Mn(III)/Mn(IV)on the surface ofα-MnO_(2)materials is the main reason for the activation of PMS to produce strong oxidizing groups to oxidize refractory organic matter.
