Example Embodiment
[0040] The present invention will be further described below in conjunction with the drawings and preferred embodiments.
[0041] The specific implementation is the waste leachate sewage treatment process of a waste incineration power plant, which has a daily waste treatment capacity of 1,200 tons. The leachate produced by garbage dumping is 300 tons per day. This leachate is a high-concentration organic sewage containing high-concentration ammonia nitrogen, organic matter and other pollutants. In this embodiment, when the landfill leachate enters the system, COD Gr (Chemical oxygen demand) peak value reaches 70,000mg / L, BOD 5 (Five-day biochemical oxygen demand) peak value reaches 30000mg / L, SS (suspended matter) reaches 6000mg / L, the average value is around 3000mg / L, and the peak value of ammonia nitrogen reaches 2000mg / L.
[0042] Such as figure 2 , Landfill leachate is first collected through a sump, and a pump pit is set at the bottom of the sump to regularly pump away the sl...
