Problems solved by technology

The effluent effect of the traditional sludge treatment process is often affected by environmental factors (climate, seasons, different sources of sludge, etc.) and appears unstable. The same problem faced by almost all sludge treatment plants is the disposal of sludge after deposition and the resulting secondary pollution problem
In addition, the treatment of sludge from some special sources still requires special chemical means, which causes more serious pollution to the environment.

Embodiment Construction

[0014] The sludge treatment high-efficiency combined functional bacteria described in the present invention is mainly used for sludge ecological treatment, and the basic principle of its ecological treatment can be found in 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 decompo...

Abstract

The invention discloses high-efficiency combined functional bacteria for sludge treatment. The high-efficiency combined functional bacteria comprise the following six microbes: bacillus licheniformis, bacillus subtilis, bacillus lentus, bacillus megaterium, bacillus thuringiensis and bacillus cereus. A culture method for the microbes comprises the following steps of: sampling; culturing in a culture medium; separating target strains; performing index analysis on the separated strains; identifying species; mixing; and optimizing. The functional bacteria are quick in multiplication and have obvious effect of removing phosphorus from sludge in the process of decomposing organic matters, so that the sludge treatment effect ensures that the sludge reaches the national emission standard, and the sludge discharge can be greatly reduced.

Description

【Technical field】 [0001] The invention relates to a high-efficiency combined functional bacteria for sludge treatment. 【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 sedimentatio...
