摘要: 高级氧化技术处理垃圾渗滤液是利用电解法制备的羟基自由基活性氧药剂对原液进行预处理，对膜生物反应器(MBR)处理后的水样做末端深度处理。原液预处理结果显示：COD由9000 mg/L降低至5270 mg/L，末端深度处理结果显示：COD由2000 mg/L降低至506 mg/L。原液预处理结果显示重金属含量Pb降低了57.2%，As降低了26.3%，Cd降低了18.7%，有毒有害的有机物如酚类、大分子烷烃类、生物难降解的羧酸类等有机物经过末端深度处理后均显著降低。该技术对改善垃圾渗滤液的处理工艺、减轻生物处理的负荷、提升处理效率，灭杀病原微生物，消除臭味，降低处理成本，具有重要参考价值。
Abstract: Treatment of landfill leachate with advanced oxidation technology is to do pretreatment on landfill lea-chate using hydroxyl radical reactive oxygen agent prepared by electrolysis, and terminal advanced treatment on water samples treated by membrane bioreactor (MBR). The results of pretreatment showed that: COD decreased from 9000 mg/L to 5270 mg /L. The results of advanced treatment showed that: COD decreased from 2000 mg/L to 506 mg/L. The content of heavy metals showed that: Pb decreased by 57.2%; As decreased by 26.3%; Cd decreased by 18.7%. Organic alcohols, organic acids, phenols were decreased significantly. This technology can improve the treatment process of landfill leachate. It can reduce the load of biological treatment and improve the processing efficiency. What’s more, it can kill pathogenic microorganisms and eliminate the smell. Using advanced oxidation technology can lower the cost of treatment.
