Domestic garbage fermentation bin and domestic garbage fermentation process

Abstract

The invention discloses a domestic garbage fermentation bin and a domestic garbage fermentation process. The domestic garbage fermentation bin comprises a fermentation bin body. A waterproof wall is disposed outside the fermentation bin body. A sprinkling system is disposed inside the fermentation bin body. An under-grate percolate tank is disposed at the bottom of the fermentation body and communicated with a filter tank. A water grate is disposed on the under-grate percolate tank. The filter tank is connected with a biogas recovery tank through a gate valve and a pipeline. A valve handle is disposed on the gate valve. The domestic garbage fermentation bin is simple in structure and convenient in use. The domestic garbage fermentation bin is used to quickly and scientifically recover fermented percolate, the recycled biogas from the domestic garbage fermentation bin is used to generate power or supply heat, and accordingly reuse of waste is achieved, and the national requirement on 'reduction, reclamation, decontamination and industrialization' of urban garbage is completely met.

Description

technical field [0001] The invention relates to a fermentation bin and a fermentation treatment process thereof, in particular to a domestic garbage fermentation bin and a fermentation treatment process thereof. Background technique [0002] At present, the common garbage disposal methods mainly include composting, landfill, and incineration. Usually, organic compost made from garbage after fermentation is a kind of garbage disposal method that is currently widely used and has a good effect. The method is to send the sorted garbage organic matter into the fermentation bin for fermentation, and use the microorganisms in the garbage to decompose the organic matter to generate heat, so that the temperature in the garbage pile layer in the bin can be raised to a certain temperature, and then a certain temperature is maintained. Time, to achieve the purpose of killing pathogenic microorganisms and viruses in the garbage. The fermentation bin used in this method is equipped with a...

The method is to send the sorted garbage organic matter into the fermentation bin for fermentation, and use the microorganisms in the garbage to decompose the organic matter to generate heat, so that the temperature in the garbage pile layer in the bin can be raised to a certain temperature, and then a certain temperature is maintained. Time, to achieve the purpose of killing pathogenic microorganisms and viruses in the garbage. The fermentation bin used in this method is equipped with a leachate collection device at the bottom of the bin. The leachate generated during the fermentation process enters and collects through the pores of the bottom cover of the bin. During the fermentation process, the oxygen required for microbial production and reproduction is also supplied by the fan through the pores on the cover plate. This method of recovering leachate and feeding through holes at the bottom is often due to fine particles Garbage clogs the pores and cannot perform this function

When the moisture content of the garbage is high, if the excess water cannot be removed in time, the pores of the garbage will form a water film, which will affect the reproduction of microorganisms; similarly, when the pores are blocked, the anaerobic fermentation of microorganisms will not only prolong the fermentation cycle, but also produce methane. The main gas and odor, resulting in secondary pollution of the environment, especially in large waste treatment plants, there is a safety hazard of explosion when the output of methane is large
