Problems solved by technology

[0005] However, relying only on the original microorganisms in nature to degrade garbage, the cycle is too long and the efficiency is poor. Therefore, the method of adding high-concentration microbial agents is generally used in the treatment of garbage, which can not only greatly improve the treatment efficiency, but also has no harm to the environment.

Embodiment 1

[0025] A method for microbial treatment of domestic waste, comprising the steps of:

[0026] 1) Weigh a certain amount of biological treatment agent, add water according to 200% of its weight, and stir evenly in a mixer to obtain the garbage treatment agent;

[0027] 2) Put the garbage treatment agent prepared in step 1) into the garbage machine according to 10% of the garbage weight, and stir at 200rpm;

[0028] 3) Ferment for 24 hours, then add 10% of the initial weight of new garbage, and stir at 200rpm;

[0029] 4) Repeat step 3) for 3 times;

[0030] 5) Then add 10% of the initial weight of the garbage treatment agent, continue the garbage degradation treatment, and so on.

[0031] The above-mentioned biological treatment agent is composed of a microbial agent and a carrier, and its mass ratio is 1:4. The components of the microbial agent and their mass ratios are respectively: 30 parts of Bacillus cereus, 300 parts of Lactobacillus acidophilus, 100 parts of Bacillus s...

Abstract

The invention relates to a microbial treatment method for domestic garbage. A biological treatment agent containing bacillus cereus, lactobacillus acidophilus, bacillus stearothermophilus, pseudomonas pseudoalcaligenes and saccharomyces cerevisiae is added with water and then is subjected to mixed fermentation with the garbage, so that the objective of degrading the garbage is achieved, and the degradation rate is up to 85%. The method is simple in operation and easy to master, moreover, has good effect on degradation of the garbage, and is beneficial for rapid treatment of the garbage and environmental protection.

Description

technical field [0001] The invention relates to the technical field of garbage treatment, in particular to a microbial treatment method for domestic garbage. Background technique [0002] With the development of the economy, the surge of population and the improvement of people's living standards, the output of municipal solid waste is increasing day by day. The white paper "China's 21st World Agenda" pointed out: "The stock of domestic solid waste in the country has reached more than 6 billion tons over the years, and there are 200 The city is surrounded by garbage.” According to statistics, the growth rate of urban garbage in my country is greater than 10%, exceeding the average annual growth rate of 8.42% in the world. How to deal with such a huge amount of municipal solid waste has become a problem of widespread concern all over the world. At the same time, the environmental pollution caused by domestic garbage and the deterioration of human settlements have become commo...
