Municipal house refuse termenting method

Abstract

The fermentation method of urban domestic refuse is characterized by that the composite liquid bacterial preparation or composite solid bacterial preparation containing photosynthetic bacteria, acetobacter, microzyme and lactic acid bacteria and refuse are mixed, then undergone the processes of anaerobic fermentation and aerobic souring treatment to shorten fermentation time, prevent the production of malodorous pollutant and reduce the breeding of flies and mosquitoes.

Description

Technical field: [0001] The invention relates to a fermentation method of municipal domestic garbage. Background technique: [0002] With the acceleration of the urbanization process, the amount of municipal solid waste is increasing day by day, and the environmental pollution caused by it is constantly aggravating. The control methods of municipal solid waste pollution include sanitary landfill, incineration, pyrolysis and composting. Some of these methods occupy a large amount of land, some have high processing costs, some have low resource utilization, and secondary pollution is common. Invention content: [0003] Aiming at the problems existing in the composting methods for domestic and foreign municipal solid waste pollution control, the purpose of the present invention is to seek a domestic waste fermentation method with short fermentation time, high decomposition rate, no foul smell, and few breeding of mosquitoes and flies. Mix the cultivated compound liquid bact...

[0003] Aiming at the problems existing in the composting methods for domestic and foreign municipal solid waste pollution control, the purpose of the present invention is to seek a domestic waste fermentation method with short fermentation time, high decomposition rate, no foul smell, and few breeding of mosquitoes and flies. Mix the cultivated compound liquid bacterial agent or composite solid bacterial agent containing photosynthetic bacteria, acetic acid bacteria, yeast, lactic acid bacteria, etc. with the organic waste sorted from municipal solid waste, and carry out anaerobic fermentation for 5 to 7 days first, and then Oxygen fermentation for 3 to 5 days to finally obtain garbage compost
