- Abstract:
- The leachate produced by the waste incineration power plant has the characteristics of complex pollutant composition, large fluctuations in water quality and quantity, high concentration of organic matter and ammonia nitrogen, difficult to treat. This paper takes a 450 m3/d leachate treatment project of the domestic waste incineration power plant as example. According to the characteristics of leachate from waste incineration power plants, UASB+A/O+MBR+two-stage RO combined treatment process was adopted to ensure that the effluent after treatment reached the Standard for Pollution Control on the Landfill Site of Municipal Solid Waste (GB 16889-2008). The amount of RO concentrate was treated by high-pressure space tube RO (STRO) reduction treatment and then re-injected incinerator. The engineering operation results in the past two years have shown that the combined process had the advantages of strong impact load resistance, qualification and stability of effluent, and space saving. The average removal rates of COD, BOD5, NH3-N, and TN were 99.8%, 99.9%, 99.0% and 98.7% respectively. The operating cost of the leachate treatment system was 47.05 yuan/m3.
