Abstract

The invention relates to a disposal system and method for garbage extracts. The system comprises a garbage extrusion device (1), a screw rod pump (6), a flotation tank (8), a buffer tank (13), a heating calcium removing device (14), an anaerobic fermenter (15), a nitrification / denitrification system (16), an ultra filtration membrane system (18), and a reverse osmosis membrane system (19) which are arranged in sequence. The method comprises the following steps: S1, squeezing garbage; S2, lifting and filtering extracts; S3, air flotation preprocessing; S4, anaerobic fermentation; S5, nitrification / denitrification and membrane processing. The system and method disclosed by the invention can improve the processing efficiency and the processing effect of the extracts of the garbage, the extracts are purified to obtain clear liquid, and the clear liquid is sent to a clear water tank, and after the clear liquid reach a standard, the clear liquid can be discharged or recycled, so that energy is saved.

Description

technical field [0001] The invention relates to the field of garbage disposal, and more specifically relates to a disposal system and method for garbage extruded liquid. Background technique [0002] Drying and sorting of municipal waste is a key step in the comprehensive treatment process of "harmless, reduced, and resourceful" waste. In my country's municipal waste, the content of inorganic impurities is high, which affects the subsequent sorting of waste and the improvement of calorific value. In order to reduce the moisture in the garbage and improve the efficiency and calorific value of garbage sorting, the primary municipal garbage is crushed, squeezed and washed before the garbage is dried, which will help to further improve the efficiency of garbage drying and sorting. However, the garbage extruded liquid produced by crushing, squeezing and washing garbage is a kind of high-concentration organic wastewater with complex components. After testing, its solid impurity ...
