Embodiment 1

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

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

[0015] Bacillus subtilis (ACCC10619), Bacillus brevis (Brevibacillus brevis; ACCC10248), Cellulomonas cartae (ACCC10527), Pseudomonas sp. (ACCC10677) were purchased from China Agricultural Microbiology Species Resource Bank (ACCC).

[0016] Acetobacterium wieringae (CGMCC 1.2033) was purchased from China General Microorganisms Resource Bank (CGMCC). Rhodanobacter fulvus (CICIM B1950) was purchased from Jiangnan University Microbial Cultures Resource Bank (CICIM) II. Culture Substrate and preparation of slant seed preparati...

Embodiment 2

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

Embodiment 3

[0036] Example 3 Application of composite bacterial agent in treating pig farm sewage and rural village sewage The liquid active bacterial agent is mixed with activated sludge to prepare mud-like bacterial agent, and the activated sludge method is used to treat pig farm sewage and rural village sewage. Table 2 and Table 3 show that the mud-like active bacterial agent has a good treatment effect on pig farm sewage and rural village sewage, in which the organic components are almost completely degraded, the removal rate of BOD is over 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...
