Leachate denitrification device of garbage transfer station and use method

Abstract

The invention discloses a leachate denitrification device of a garbage transfer station and a use method. The device comprises a primary filter tank, a regulating tank and a flocculation sedimentationtank, wherein the primary filter tank communicates with the regulating tank; the regulating tank communicates with the flocculation sedimentation tank; the flocculation sedimentation tank communicates with an ammonia stripping tank; the ammonia stripping tank communicates with a hydrolytic acidification tank; the hydrolytic acidification tank communicates with an aerobic tank; the aerobic tank communicates with an ultrafiltration membrane filter tank; the ultrafiltration membrane filter tank communicates with a disinfection tank; the disinfection tank communicates with a clean water tank; andthe regulating tank, the flocculation sedimentation tank, an anaerobic reaction tank and the hydrolytic acidification tank communicate with a sludge distributing pipe. A sludge pump is started to pump out sludge in the regulating tank, the flocculation sedimentation tank, the anaerobic reaction tank and the hydrolytic acidification tank, the sludge enters a sludge concentration tank through the sludge distributing pipe and a main sludge pipe, and the sludge is treated with a pressure filter, sludge cake is transported out; and according to the garbage penetrating fluid denitrification treatment device, the effluent quality is relatively good, the water quality index can meet the discharge requirement, and the effluent quality is stable.

Description

Technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a denitrification device for the leachate of a garbage transfer station. Background technique [0002] Landfill leachate refers to the water contained in the garbage itself, the rain and snow water and other water entering the landfill, deducting the saturated water holding capacity of the garbage and the overburden, and it is formed through the garbage layer and the overburden layer. A kind of high-concentration organic wastewater, the treatment of leachate in urban waste landfills has always been a very difficult problem in the design, operation and management of landfills. Leachate is the product of the gravity flow of liquid in the landfill, mainly from precipitation and the internal water content of the garbage itself. Since there are many factors in the liquid flow process that may affect the properties of the leachate, including physical factors, chemical factors, and...

AI Technical Summary

Problems solved by technology

The leachate of urban waste landfill is a kind of high-concentration organic wastewater with complex components. If it is directly discharged into the environment without treatment, it will cause serious environmental pollution.

For the purpose of protecting the environment, it is essential to treat the leachate. The water quality of the existing landfill leachate treatment device is poor and unstable.
