摘要
介绍了上海老港垃圾填埋场三级矿化垃圾生物反应床处理渗滤液示范工程2a来的运行情况,在短周期、多次喷灌配水的间歇运行方式下,对渗滤液处理效果好、水质适应性强。在50t/d的配水量下,三级出水的NH3-N、TSS、BOD5、TP、色度、嗅味、重金属含量等污染指标均低于渗滤液二级排放标准,COD值在1a20%的时间里满足二级排放标准,75%的时间里排放浓度低于650mg/L,全年可满足三级纳管排放标准。
Two years operation of demonstration engineering of treating leachate with tertiary mineralized waste bio - reaction bed in Shanghai Laogang Waste Landfill Site was introduced, under operation mode of short periodicity and repeated distributing water by spray intermittently, satisfying treatment effect of leachate and wide adaptability of water quality could be achieved. When the distributing water is 50 t/d, pollutants concentration including NH3 - N, TSS, BODe, TP and colority, odor, and heavy metals tertiary effluent were all below the secondary emission standard of leachate. In the time of 20% of a year, COD could reach the secondary emission standard. In the time of 75% of a year, COD emission concentration was below 650 mg/L, while it could reach the tertiary standard of discharge into municipal sewage pipeline in a whole year.
