Problems solved by technology

[0002] Most of the microbial agents used in the market for food waste fermentation are derived from traditional organic fertilizer starters or single-species starters such as Bacillus subtilis, lactic acid bacteria, yeast, etc., mainly facultative bacteria and anaerobic bacteria , belongs to the microbial strains for conventional treatment of organic waste, most of them are medium and low temperature strains, and have poor salt tolerance. In the environment where oil exists, the fermentation activity is low, and the oil cannot be effectively degraded. It is a pure fermentation product with no auxiliary ingredients added

Abstract

The invention discloses a composite microbial preparation for degrading kitchen garbage, which is prepared from the following components in parts by mass: 75 to 80 parts of microbial mixed fermentation liquor, 1 to 3 parts of fatty alcohol polyoxyethylene, 0.1 to 0.3 part of urea, 0.1 to 0.3 part of diammonium hydrogen phosphate and 18.8 to 21.4 parts of distilled water. The microorganism mixed fermentation liquor is prepared from pseudomonas aeruginosa fermentation liquor, diplococcus fermentation liquor, bacillus subtilis fermentation liquor and bacillus amyloliquefaciens fermentation liquor according to the mass ratio of 1: 1: 1: 1. After kitchen waste is treated by the composite microbial preparation, the content of grease in discharged waste water is reduced, a cleaning effect on a drainage pipe network is achieved, grease is not accumulated, and the pipe network is not blocked; meanwhile, the volume of the kitchen waste is rapidly reduced, the reduction is obvious, and large organic waste in the kitchen waste is degraded into organic particle liquid with the particle size being 2 mm or below within 18 h.

Description

technical field [0001] The invention belongs to the field of self-service terminal equipment, and in particular relates to a compound microbial preparation and a preparation device for degrading kitchen waste. Background technique [0002] Most of the microbial agents used in the market for food waste fermentation are derived from traditional organic fertilizer starters or single-species starters such as Bacillus subtilis, lactic acid bacteria, yeast, etc., mainly facultative bacteria and anaerobic bacteria , belongs to the microbial strains for conventional treatment of organic waste, most of them are medium and low temperature strains, and have poor salt tolerance. In the environment where oil exists, the fermentation activity is low, and the oil cannot be effectively degraded. It is a pure fermentation product with no auxiliary ingredients added. The technical means used in the treatment of food waste are liquid anaerobic fermentation and solid composting fermentation. T...
