Complex microbial inoculant for solid waste fermentation treatment

Abstract

The invention discloses a complex microbial inoculant for solid waste fermentation treatment. The microbial agent comprises the following components in parts by weight: 30-50 parts of a compound strain, 5-10 parts of an auxiliary material, 5-10 parts of a protective agent, 1-5 parts of an additive and 5-10 parts of rhamnolipid. According to the invention, the composite strains, especially the composite strains consisting of bacillus thermophilus, staphylococcus, ammonifying bacteria and actinomycetes, are adopted to treat the household garbage, so that the antagonism among the composite strains can be eliminated under the cooperation of rhamnolipid, auxiliary materials and other components, harmless biomass decomposition of the household garbage can be quickly and effectively completed, and the household garbage is effectively treated. The peculiar smell is eliminated. In addition, the complex microbial inoculant prepared by the invention can be suitable for a high-temperature treatment environment of 60 DEG C or above, and can be applied to degradation treatment of household garbage in a specific high-temperature environment.

Description

technical field [0001] The invention belongs to the technical field of garbage treatment, and in particular relates to a composite bacterial agent for solid waste fermentation treatment. Background technique [0002] With the increasing enrichment of people's material life, the amount of domestic waste generated is also increasing rapidly. At present, the commonly used disposal methods of domestic waste mainly include sanitary landfill and incineration. However, there are many defects in the landfill: First, the landfill occupies a lot of land, the land is a non-renewable resource, and the land resource is relatively tight; Second, it causes pollution to the environment; due to the large amount of organic matter and batteries and other substances After entering the landfill, the toxic leachate it produces will cause serious pollution to soil and groundwater. From the perspective of environmental protection, it is necessary to establish a landfill leachate anti-seepage, coll...

Problems solved by technology

However, there are many defects in landfilling: first, landfills occupy a large amount of land, which is a non-renewable resource, and land resources are relatively tight; second, it pollutes the environment; due to the large amount of organic matter and batteries After entering the landfill, the toxic leachate produced will seriously pollute the soil and groundwater. From the perspective of environmental protection, it is necessary to establish an anti-seepage, collection and treatment system for the leachate of the landfill, which will improve the technology. Difficulty, but also increased investment, complex landfill operation, difficult management, in addition, methane, hydrogen sulfide and other waste in the landfill must also be disposed of to ensure that explosion-proof and environmental protection requirements are met; 3. Waste of resources, a large amount of garbage piled in In the landfill, some materials and energy cannot be used, which causes a certain degree of waste of resources

During the use of traditional garbage incinerators, garbage is put on the grate in the incinerator for incineration. However, when the garbage on the grate is burning, the newly put in garbage instantly covers the burning garbage, which is easy Extinguish the flames, resulting in unstable temperature in the furnace, insufficient garbage incineration, and insufficient garbage incineration will easily produce harmful gases

At the same time, the composition of the garbage is complex, and various combustibles have different properties, which makes the phenomenon of clinker, slag, sintering and other phenomena during the incineration process of the garbage, and the combustion rate is low.

The combustible gas in the flue gas and the combustible matter in the fly ash cannot be completely incinerated, and there are many harmful components in the finally discharged flue gas, which pollutes the environment
