摘　　要：某危险废物填埋场于2013年服役,服役年限11年,因为其填埋物料组分多样,污染物成分复杂,导致危险废物填埋场运营后期的渗滤液具有高COD、高氨氮、高盐的特点。改造后渗滤液处理系统采用“MVR+DTRO+AO”的组合工艺,综合产水率70%,出水水质可以满足《危险废物填埋污染控制标准(GB 18598-2019)》中间接排放的要求。A hazardous waste landfill site,which began operation in 2013 with a service life of 11 years,contains diverse materials and complex pollutants,leading to the leachate produced in the later stages of its operation being characterized by high COD(Chemical Oxygen Demand),high ammonia nitrogen,and high salinity.After renovation,the leachate treatment system employs a combined process of“MVR(Mechanical Vapor Recompression)+DTRO(Disc Tube Reverse Osmosis)+AO(Anaerobic-Oxidation)”,achieving an overall water production rate of 70%.The quality of the effluent meets the indirect discharge requirements set forth in the“Hazardous Waste Landfill Pollution Control Standards(GB 18598-2019)”.
