Device for collecting organic solid waste composting fermentation leachate

Abstract

The invention discloses a device for collecting organic solid waste composting fermentation leachate. The device comprises a main pipeline and a timed air blower and a leachate collecting tank connected with the main pipeline, wherein a plurality of guide and drainage grooves are axially formed on the top of the main pipeline at intervals; a top seal plate is arranged above the guide and drainage grooves; the top seal plate is narrower than the guide and drainage grooves; eyelets are formed on the top seal plate; arc-shaped side sealing plates are arranged on the left and right sides of the top seal plate; the top seal plate is connected with the main pipeline through the side seal plates. The top seal plate and the side seal plates form a hollow ridge channel which extends upward. When the air blower blows air into the main pipeline, gas can be collected to the channel and is leaked through the eyelets, so that the purpose of supplying gas by the organic solid wastes is achieved as to provide oxygen to microbial activities in the fermentation process. Meanwhile, gas blows impurities at the eyelets to prevent the eyelets from being blocked to affect collection of the leachate. The device is a leachate collecting device which is simple in structure and low in cost and has the advantages of being convenient to maintain, easy to assemble and modularize.

Description

technical field [0001] The invention belongs to the field of organic solid waste treatment and comprehensive utilization, and in particular relates to a leachate collection device applied to organic solid waste composting fermentation. Background technique [0002] In recent years, with the rapid progress of urbanization in China, a large amount of municipal organic solid waste, such as the associated product sludge of domestic sewage treatment, has become a problem that plagues environmental governance. Because sludge contains high organic matter, nitrogen, phosphorus and various nutrients needed for plant production, it is an important source of organic fertilizer. Through composting and fermentation, natural microorganisms or inoculated microorganisms can be used to rapidly detoxify materials under aerobic conditions. Deodorization and decomposing will generate a high temperature of 60-70°C, thereby killing pathogenic bacteria and insect eggs in the material, and turning ...

Problems solved by technology

The strip pile is to mix the raw materials into strip piles and turn them regularly. The disadvantage is that it takes 1-4 months to complete the fermentation, which is too long; The investment is too large and it is difficult to promote quickly; static aeration is a composting method that uses ventilation pipes for artificial ventilation. Fermentation can be completed in 3-5 weeks without turning over the compost. The time is short and the investment is small, so it has the advantages Broad application prospects
