Embodiment 1-5

[0043] Among the following examples 1-5:

[0044] 1. The preservation number of Bacillus thermophiles is: CGMCC NO.5818, the preservation time is: February 29, 2012, the preservation unit is: General Microbiology Center of China Microorganism Collection Management Committee; the preservation address is: Beichen, Chaoyang District, Beijing, China No. 3, No. 1 West Road, Institute of Microbiology, Chinese Academy of Sciences. The bacterium was isolated from water samples of high-heat oil wells, and was obtained by repeated domestication and cultivation at 60°C for five rounds (each round was one week) with crude oil as the only carbon source.

[0045] 2. Thermophilus Thermus thermophilus UTM802 strain was obtained from sludge compost in the high-temperature period through high-temperature enrichment, separation and purification, and was preserved in the China Microbiological Culture Collection Management Committee on June 4, 2012. General Microbiology Center, Address: No. 3, Ya...

Abstract

The invention discloses a biological agent for improving aerobic fermentation efficiency of organic waste. The biological agent is prepared from the following raw materials: 40-60 parts of bacillus stearothermophilus, 40-60 parts of thermophilic bacteria, 40-60 parts of lactobacillus thermophilus, 20-30 parts of bacillus subtilis, 20-30 parts of bacillus subtilis subsp. subtilis, 10-20 parts of alcaligenes, 10-20 parts of bacillus circulans, 10-20 parts of aspergillus fumigatus, 5-15 parts of trichoderma viride, 5-15 parts of geotrichum candidum, 3-10 parts of white rot fungi, 3-10 parts of brown rot fungi, 1-5 parts of green algae and 1-5 parts of blue algae. A preparation method comprises the following steps of: (1) weighing the raw materials; (2) activating strains; (3) compounding mixed strains; (4) preparing a primary seed solution; and (5) preparing the biological agent. The biological agent disclosed by the invention can reduce generation and emission of odor in a composting process and reduce loss of nutrient substances such as nitrogen, so that the aerobic fermentation efficiency of the organic waste is improved.

Description

technical field [0001] The invention relates to the technical field of biological bacterial agents, in particular to a biological bacterial agent for improving the aerobic fermentation efficiency of organic waste and a preparation method thereof. Background technique [0002] Organic waste refers to solid or liquid organic objects and substances that have lost their original use value or have not lost their use value but have been discarded or abandoned during production activities, including agricultural organic waste (mainly including crop straw, vines, livestock and poultry manure and aquatic waste, etc.), industrial organic waste (mainly including high-concentration organic wastewater, organic waste residue, etc.), municipal organic waste (mainly including landscaping waste, municipal sludge, animal inclusions in slaughterhouses, kitchen Garbage, etc.) three categories. With the rapid development of my country's economy and the continuous improvement of people's living ...
