NOVELTY - Processing leachate from garbage incineration plant comprises placing to be processed garbage leachate into a grid depositing tank and removing percolation liquid, suspended substance and sediment from the garbage leachate, stirring obtained filtrate present in an adjusting tank, adjusting a flow rate of the fluid penetrating in the primary sedimentation tank, placing obtained product into a middle part of an upflow anaerobic sludge blanket reactor in a first water tank, passing supernatant liquid into coagulating flocculation tank, and passing the clean water to a treatment system.    USE - The method is useful for processing leachate from a garbage incineration plant (claimed).    ADVANTAGE - The method is capable of economically processing the high index leachate with improved water quality and operation stability.    DETAILED DESCRIPTION - Processing leachate from a garbage incineration plant comprises: (1) placing to be processed garbage leachate into a grid depositing tank, and removing percolation liquid, suspended substance and sediment from the garbage leachate; (2) stirring obtained filtrate present in an adjusting tank using a bottom diving stirrer and then pumping penetrating fluid into a primary settling tank after 5-7 days; (3) adjusting a flow rate of the penetrating fluid in a primary sedimentation tank of less than 30 mm/seconds and then depositing for 1-1.5 hours, and removing deposition of sludge and organic matter in the primary sedimentation tank; (4) placing obtained product into a middle part of an upflow anaerobic sludge blanket (UASB) reactor in a first water tank, pumping the water to a second water tank, passing the clear liquid from the first water tank to the second water tank, and maintaining water temperature in the UASB reactor at 30-35 degrees C; (5) stirring the product in an aeration tank, performing nitration reaction process for the microorganism in the aeration tank with pH value of 7.5, nitrifying liquid entering from the aeration tank into a reflux water tank for 5-10 times, and separating mud-water in the aeration tank by sedimentation process; (6) passing the supernatant liquid into a coagulating flocculation tank, removing the suspended solids (SS) and chemical oxygen demand dichromate (CODCr) of supernatant solution in a secondary sedimentation tank and then pumping to a processing system through a water pump; and (7) passing the clean water to a treatment system, and filtering using a ultra-filtration and nanofiltration filter.
