摘要
根据某垃圾填埋场渗滤液水质特征,采用混凝-厌氧折流板反应器-一级接触好氧-接触厌氧-二级接触好氧-Fenton氧化-上流式曝气生物滤池组合工艺处理该渗滤液。在处理水量为50 m3/d的条件下,出水COD、氨氮质量浓度可分别控制在50、5 mg/L以下,去除率分别可达93.21%和96.01%,出水色度为10倍,完全达到生活垃圾填埋场污染控制标准(GB 16889-2008)中表2的排放标准。在不考虑人工及折旧费的情况下,此填埋龄较短的渗滤液处理成本仅为8.66元/m3,具有良好的经济效益和环境效益。
According to the characteristics of the leachate from one landfill,coagulation-two stage A/O-Fenton oxidation-up-flow biological aerated filter processes were applied to treat the leachate.It was showed that under the condition of the feed water was 50 m3/d,the concentration of COD、 ammonia nitrogen in effluent could be stabilized blew 50 mg/L,5 mg/L respectively.The removal rates of COD and ammonia nitrogen were 93.21% and 96.01%.Besides,the chromaticity was 10times.The effluent quality had met the criteria specified in standard for pollution control on the landfill site for domestic waste(GB 16889-2008).Finally,the leachate treatment cost of new landfill was only 8.66 yuan/m3 without counting labor and depreciation cost.It had been shown to have great economic benefits and environmental benefits.
