NOVELTY - Treating rubbish percolate comprises (i) discharging the rubbish percolate into an adjusting pond; (ii) discharging to a coagulation reaction pond, and depositing; (iii) discharging into a heating system; (iv) pumping percolate to a expanded granular sludge bed for anaerobic reaction; (v) discharging the percolate into a sequence batch activated sludge reactor for aerobic reaction; (vi) placing a dynamic film bioreactor in the pond, and filtering; (vii) discharging the filter liquid; (viii) returning the supernatant into the adjusting pond; and (ix) filter pressing the dreg, and land filling.    USE - The method is useful for treating rubbish percolate.    ADVANTAGE - The method is stable and economical.    DETAILED DESCRIPTION - Treating rubbish percolate comprises (i) discharging the rubbish percolate into an adjusting pond, and homogenizing with water for 9-15 days; (ii) discharging the treated rubbish percolate into a coagulation reaction pond, adding coagulant and flocculant, depositing the rubbish percolate with the agents after 8-15 minutes of reaction, where the depositing time is greater than or equal to 2 hours; (iii) discharging the deposited percolate into a heating system, and heating the liquid to 36-38 degrees C; (iv) pumping the heated percolate into a expanded granular sludge bed for anaerobic reaction, transporting the methane produced by the reaction to a generator set, using the electricity for providing power, transferring the waste heat to the heating system, where the reaction time is 6-12 hours, the temperature of the particle bed is 35-37 degrees C, the pH value is 7-8, the volume loading is 12-17 kg chemical oxygen demand/(m3/day), and the rising flow speed of the percolate is 4-6 m/hour; (v) discharging the reacted percolate into a sequence batch activated sludge reactor for aerobic reaction, where the volume loading of the sequence batch activated sludge reactor is 0.1-0.18 kg biological oxygen demand/(kg mixed liquor suspended solids/day), and the stay time of the percolate in the reactor is 7-15 days; (vi) placing a dynamic film bioreactor in the pond, filtering the percolate by the bioreactor, initial filtering for 30 minutes, forming dynamic film on the bioreactor by the active sludge flocculation, filtering the percolate by the filter film of a filtering system, where the organic pollutant removing rate is 70-80%, placing a central water pond in the back of the bioreactor, intercepting the outlet water of the initial operation and back wash, equipping aeration at the bottom of the bioreactor, where the ratio of gas to water is 15:1, back washing with clean water and air film assembly (the water quantity is less than 75% of the designed one), where the water quantity of back wash is 2 times of the outlet water, and discharging the filter liquid into the filtering system; (vii) discharging the filter liquid into a concentrated pond for depositing; (viii) returning the supernatant into the adjusting pond, discharging the deposited sludge dreg into a filter press; and (ix) filter pressing the sludge dreg after discharging in the filter press, discharging the filter pressing liquid to the adjusting pond, and transporting to a landfill for land filling.
