Problems solved by technology

At the same time, a certain amount of solid waste will also be produced in the industry. For example, in the production process of stevioside, a large amount of stevia slag will be left after the stevia sugar is extracted. These stevia slag will be sent to the garbage station, which will increase the garbage disposal The workload; the extraction of Chinese herbal medicine components will also bring a lot of Chinese herbal medicine dregs, and this part of Chinese herbal medicine dregs will be discarded

Abstract

The invention relates to an ins-situ pretreatment method of solid organic waste resources (catering wastes, domestic garbage, garbage in vegetable markets, brewer grains, distiller grains, stevia rebaudiana waste residues, traditional Chinese dregs, wastes in slaughter houses, wastes in culturing farms and the like). Mixed bacterial are added into the organic wastes at temporary storage places ofthe solid organic wastes (garbage cans, sewer manholes, scrapyards and the like) and stood and treated in a natural state. The invention discloses a method for effectively solving the treatment on the solid organic wastes from the generation to the treatment, which thoroughly controls the hazards brought by the solid organic wastes, such as mosquito breeding, stink, pathogenic microorganism infection and the like and provides prerequisite conditions for post treatment of the solid organic wastes and realization of hazard-free treatment, reclamation and reduction of waste resources.

Description

technical field [0001] The invention relates to a method for pretreatment of solid organic waste, specifically, by mixing microorganisms in the solid organic waste storage container or storage place to treat it, thereby controlling the pollution caused by the solid organic waste from the source. Hazards such as mosquito breeding, stench, and pathogenic microorganism infection provide prerequisites for the post-processing of solid organic waste and the recycling and reduction of waste resources. Background technique [0002] At present, with the continuous growth of population, the improvement of living standards and the development of industry and agricultural economy, a large amount of solid organic wastes are produced every day. If these solid organic wastes are disposed of by landfill or incineration, a large amount of resources and occupy a large amount of land. Among the garbage generated, most of the garbage from restaurants, domestic garbage and vegetable markets are...
