摘　　要：垃圾渗滤液中有机物和氨氮浓度高,难生物降解的大分子有机物多,可生化性差,C/N比低。本工程采用“水解酸化+AOAO+两级臭氧催化氧化-BAF”组合工艺处理垃圾渗滤液,出水执行《生活垃圾填埋场污染控制标准》(GB 16889-2008)表2标准(以下简称“表2标准”)。运行结果表明,该系统可操作性强,运行稳定且成本低,污染物去除率高,出水CODCr<100 mg/L、氨氮<25 mg/L、总氮<40 mg/L,水质完全满足排放要求,值得推广。Landfill leachate is high in organic matter and ammonia nitrogen, contains more macromolecular organic matter that is difficult to biodegrade with poor biodegradability and low C/N ratio.This project adopts the combination process of “HASB-AOAO-two stage ozone catalytic oxidation BAF” to treat the landfill leachate, the effluent shall comply with table 2 of Domestic Waste Landfill Pollution Control Standard(GB16889-2008)(hereinafter referred to as “Table 2standards”). The operation results show that the system has strong operability, stable operation and low cost, high pollutant removal rate, CODCr<100 mg/L,ammonia nitrogen < 25 mg/L, total nitrogen <40 mg/L, water quality fully meets the discharge requirements, worthy of promotion.
