Problems solved by technology

Many technical solutions have been disclosed in the prior art, mostly using compound bacterial agents to improve fermentation efficiency, and at the same time using the high temperature obtained by short-term fermentation to kill germs and insect eggs. However, the preparation method is complicated, which obviously leads to an increase in the cost of the bacterial agent; the publication number is CN102765972A patent document, through the use of new types and components of the compound bacterial agent to synergistically treat rural domestic waste, It can effectively accelerate the fermentation efficiency of rural domestic waste; patent documents such as CN101993831A and CN101787350A can also have the same effect, but there is a problem in the above-mentioned technical solutions, that is, the high temperature generated during fermentation is harmful to mosquitoes and miscellaneous bacteria. It is difficult to maintain a stable killing effect, and the treatment of heavy metals in rural domestic waste is not in place. Therefore, after the rural domestic waste is fermented and processed into compost, the compost has inclusions during use. The problem of germs and heavy metals

Embodiment 1

[0050] Take 1 part of Bacillus subtilis, 0.5 part of Bacillus licheniformis, 1 part of saccharomyces, 0.5 part of Bacillus lateralis, 0.2 part of cellulase and 0.5 part of protease according to the mass ratio.

[0051] After sorting the stones, plastics, glass and metal impurities in the rural domestic waste, the bacterial agent can be inoculated into the sorted rural domestic waste according to the mass ratio of 300g / t under an aerobic environment, Among them, the number of live bacteria per gram of bacterial agent is not less than 20 billion.

Embodiment 2

[0053] Take 3 parts of Bacillus subtilis, 1.5 parts of Bacillus licheniformis, 3 parts of saccharomyces, 1.5 parts of Bacillus lateralis, 1 part of cellulase and 1.5 parts of protease according to the mass ratio.

[0054] After sorting the stones, plastics, glass and metal impurities in the rural domestic waste, the bacterial agent can be inoculated into the sorted rural domestic waste according to the mass ratio of 500g / t under an aerobic environment, Among them, the number of live bacteria per gram of bacterial agent is not less than 20 billion.

Embodiment 3

[0056] Take 2 parts of Bacillus subtilis, 1 part of Bacillus licheniformis, 2 parts of saccharomyces, 1 part of Bacillus lateralis, 0.5 part of cellulase and 1 part of protease according to the mass ratio.

[0057] After sorting the stones, plastics, glass and metal impurities in the rural domestic waste, the bacterial agent is inoculated into the sorted rural domestic waste according to the mass ratio of 400g / t under an aerobic environment. Among them, the number of live bacteria per gram of bacterial agent is not less than 20 billion.

[0058] Effect example:

[0059] After sorting out masonry, glass, plastic and metal from the rural domestic garbage in the same garbage dump, they are equally divided and used as the treatment group and control group for fermentation and fermentation treatment. The control group was treated with natural fermentation, and the treatment group was inoculated with 4 kg of bacterial agent described in Example 3 on the 3rd day of natural fermentat...

Abstract

The invention belongs to refuse fermentation treatment technologies, and particularly relates to rural household refuse microbial inoculum and a using method and application thereof. The microbial inoculum is mainly prepared from bacillus subtilis, bacillus licheniformis, saccharomycetes, bacillus laterosporus, cellulase and protease. The fermentation microbial inoculum provided by the invention can be used to quicken fermentation efficiency of rural household refuse, can heavy metal in the rural household refuse at the same time and kill germs with high efficiency.

Description

technical field [0001] The invention belongs to a garbage fermentation treatment process, and in particular relates to a rural domestic garbage fermentation bacterial agent and its use method and application. Background technique [0002] Rural domestic waste and its impact on urban image and civilization construction, the current treatment methods of rural domestic waste are basically divided into: landfill, incineration and accumulation fermentation. The landfill method consumes a lot of open space to dispose of rural domestic waste, and this method is an evasive solution that does not decompose rural domestic waste in a real sense. At the same time, heavy metal pollutants in rural domestic waste will cause soil pollution again ;Incineration can effectively deal with rural domestic waste, but this method will not only produce a large amount of polluting flue gas and carcinogenic product dioxin, but also cause the loss of recyclable resources in rural domestic waste, which ...
