Example Embodiment

[0013] Example 1 1. Materials and source strains: Perchlorate degrading bacteria (Azospira oryzae; DSMZ13638) and Caldilinea aerophila (DSMZ14535) were purchased from the German Collection of Microbial Cultures (DSMZ).

[0014] Methylocella silvestris (Methylocella silvestris; ATCC700799), Nitrobacter winogradskyi (ATCC25391), Nitrosomonas europaea (ATCC25391) were purchased from the American Microbial Species Collection (ATCC).

[0015] Bacillus subtilis (ACCC10619), Brevibacillus brevis (ACCC10248), Cellulomonas cartae (ACCC10527), Pseudomonas sp. (ACCC10677) were purchased from Chinese agricultural microorganisms Kind of resource library (ACCC).

[0016] Acetobacterium wieringae (Acetobacterium wieringae; CGMCC 1.2033) was purchased from China Common Microbial Species Resource Bank (CGMCC). Rhodanobacter fulvus (CICIM B1950) was purchased from Jiangnan University Microbial Species Resource Bank (CICIM) 2. Cultivation Base and preparation slant seed preparation: Streak and separat...

Example Embodiment

[0034] Example 2 Application of the compound bacterial agent in the degradation rate of sludge. The bacterial agent of the above example 1 was applied to the sludge reduction of the Ministry of Environment and Forestry of Gifu Prefecture, Japan. The operation method was to add 20g of the sludge containing the compound bacterial agent to the test tube. The group added 4g of normal sludge, added sludge for 36 consecutive days, and removed the supernatant liquid. The following data is obtained. After the addition of bacterial agents, the sludge degradation rate is significantly accelerated, and the added sludge is almost completely degraded, and the maximum sludge reduction load is 0.041d -1 , Only 0.018d without adding bacteria -1 .

Example Embodiment

[0036] Example 3 Application of composite bacterial agents in the treatment of sewage from pig farms and rural villages. Liquid active bacterial agents are mixed with activated sludge to prepare sludge bacterial agents. The activated sludge method is used to treat sewage from pig farms and rural villages. Table 2 and Table 3 show that the mud-like active bacteria agent has a good treatment effect on the sewage of pig farms and rural villages. Among them, the organic components are almost completely degraded, the BOD removal rate is more than 99%, and the removal of nitrogen and phosphorus is also good. Effect.

Abstract

The invention discloses a composite fungicide for rapid degradation of organic waste and applications thereof. The composite fungicide is a liquid fungicide prepared by mixing a functional fungicide and a characteristic fungicide in a volume ratio of (2-4):1, and is used in the technical field of treatment of municipal solid waste and livestock and poultry manure and sludge reduction. The composite fungicide disclosed by the invention has the advantage that the functional fungicideand the characteristic fungicide are obtained by pure culture, so that the function of the fungicide is enhanced and simultaneously the stability of the fungicide is improved. When the product is used in waste treatment in a composting plant, a refuse treatment plant or a personal treatment yard, the activity of the total microflora and lignocellulose-degrading microorganisms in a composting pile can be enhanced, the combined composting process of vegetables, flowers and straws can be distinctly accelerated, and the decomposing time is shortened.

Description

technical field [0001] The present invention relates to a microbial composite bacterial agent, specifically a composite bacterial agent for rapidly degrading organic wastes and its application, that is, for organic wastes such as urban organic waste, sewage treatment plant sludge, solid livestock and poultry manure, Composite microbial agent for biological treatment of domestic sewage, kitchen waste, etc. and its application. Background technique [0002] Microbial treatment technology is the leading technology in environmental governance. The reason is that microbial technology has the advantages of high efficiency, low operating cost, wide application range, and mature technology. Bioaugmentation technology has developed rapidly in recent decades. [0003] Bioaugmentation technology is to add dominant strains to the sewage and wastewater treatment system, and increase the microbial flora that responds efficiently to a specific environment or special pollutants through natu...
