Embodiment 1

[0028] The multi-element waste light simplified energy saving and emission reduction aerobic and anaerobic composting system of this embodiment, such as figure 1 As shown, it includes frame 20, two cylindrical fermenting bins 8, ventilation-crushing composite device 47, deodorizing device 12 and liquid storage tank 10. In order to facilitate movement, the bottom of frame 20 is provided with rollers 19. The fermentation chamber 8 is sealed and installed on the frame 20, the deodorization device 12 is provided with an air inlet 21 and a gas emptying valve 11, and the gas generated in the fermentation chamber 8 is collected to the deodorization device in time 12, after being treated by the deodorizing device 12, it is emptied. In this embodiment, the deodorizing device 12 adopts a biological filter, and of course other existing gas deodorizing devices can also be used.

[0029] Such as figure 2 As shown, the fermentation bin 8 includes a coaxial first stainless steel cylinder ...

Embodiment 2

[0039] This embodiment is an improvement on the basis of Embodiment 1, and the difference is that there is only one fermentation chamber 8 in this embodiment.

Abstract

The invention relates to a multi-element waste light simplified energy-saving emission-reducing aerobic and anaerobic composting system. The system comprises a rack, a cylindrical fermentation bin anda ventilation-crushing composite device. The fermentation bin is hermetically arranged and mounted on the rack. The fermentation bin is divided into three layers from outside to inside, namely a leachate anaerobic fermentation cavity, a ventilation cavity and a material aerobic fermentation composting cavity in sequence, a spring-back water baffle is arranged at the bottom of the ventilation cavity, the ventilation-crushing composite device is arranged in the material aerobic fermentation composting cavity, and gas produced in the fermentation bin is discharged after being treated to reach the standard. According to the invention, harmless cleaning treatment of perishable organic garbage can be carried out by taking village and town families as units.

Description

technical field [0001] The invention relates to a system capable of performing aerobic and anaerobic composting on multiple wastes such as perishable garbage, kitchen waste and end vegetables, and belongs to the technical field of domestic garbage treatment. Background technique [0002] According to the survey by the Ministry of Health, the current scale of domestic waste generation in rural areas in my country is about 300 million tons per year. However, according to statistics from the Ministry of Housing and Urban-Rural Development, in 2016, the harmless disposal rate of domestic waste in my country's administrative towns and townships was only 44.99% and 15.82%, and only 62.2% of administrative villages treated domestic waste. Freshly produced domestic garbage and old garbage have encroached on a large amount of land, even farmland, and pollution of surface water, groundwater, soil and air is widespread. [0003] According to statistics, the per capita generation of ru...
