Embodiment Construction

[0014] The combined bacteria described in the present invention is mainly used for sludge ecological treatment, the basic principle of its ecological treatment please refer to figure 1 and figure 2 shown. The main components of biomass are polysaccharides, proteins and fats. Under natural circumstances, these substances rely on microorganisms in the environment to slowly decompose them to maintain the balance of the entire ecological environment. Sludge ecological treatment uses this basic principle to isolate a group of microbial flora that have a specific degradation ability to organic waste in sludge from nature, and combine them into a group of combined functional bacteria after isolation and identification. Under suitable conditions (temperature, humidity, air, etc.), these special combined flora can effectively produce protease, lipase, hydrolase, cellulase, amylase, etc., so that macromolecular substances can be decomposed into microbes that can be decomposed by micr...

Abstract

The invention discloses a combined strain. The combined strain comprises the following six kinds of microorganisms: Bacillus licheniformis, Bacillus subtilis, Bacillus lentus, Bacillus megaterium, Bacillus thuringiensis and Bacillus cereus. The cultivation of the microorganisms comprises the following steps of: sampling, culturing in a culture medium, separating target strains, performing index analysis on the separated strains, performing species identification, compatibilizing and optimizing. The functional strain can proliferate quickly in the process of decomposing organic matter, has a remarkable effect of dephosphorizing sludge, ensures that the treatment effect of the sludge meets the national emission standard, and can greatly reduce the discharge amount of the sludge.

Description

【Technical field】 [0001] The invention relates to a combination bacterium. 【Background technique】 [0002] Like animals and plants, microorganisms are one of the three major species in nature, and in the entire ecological cycle system, microorganisms are the decomposers of organic waste from animal and plant residues. Therefore, microorganisms play a very important role in the field of ecological cycle and environmental protection, that is, the processors of sludge and garbage. Almost all sludge treatment is accomplished by the action of microorganisms, and in sludge and sewage treatment, not only microorganisms are required to decompose and remove various harmful substances, but also microorganisms are required to deodorize. The type, function and quantity of microorganisms determine the treatment speed and treatment effect of sludge and sewage to a large extent. [0003] The traditional sludge treatment methods are sedimentation, anaerobic, aerobic aeration and other pro...
