Method for deodorizing garbage by utilizing composite microbial agent

Abstract

A method for deodorizing garbage by utilizing a composite microbial agent comprises the steps: taking the composite microbial agent as a bacterial source, taking water harmless to a strain as a carrier, cooperating with a strain-required nutrient source, preparing a composite microbial deodorant, then utilizing the composite microbial deodorant to be blended with the same amount of clear water to obtain a bacterial liquid, and directly spraying the bacterial liquid in an atomization state to a garbage material, so as to reach the purpose of deodorization. Through the implementation of the method, the composite microbial deodorant liquid is simple in preparation process and can be successfully rejuvenated through room temperature culture, and no pollutants are produced in the rejuvenation process. In an application process, the deodorant firstly absorbs malodorous substances in gas through the larger specific surface area and then converts the malodorous substances into other odorless substances through metabolism of microbial flora. The used strain used in the implementation of the method has an official registration certificate awarded by the nation and is harmless to both the environment and surrounding organisms, so that the use of the compound biological deodorant does not cause secondary pollution to the environment, and the environmental load is low.

Description

technical field [0001] The invention belongs to the field of biotechnology, and in particular relates to a method for deodorizing garbage by using a composite microbial inoculant. Background technique [0002] The annual output of urban waste in my country is nearly 150 million tons, and it is increasing at a rate of about 8% every year. Nearly 2 / 3 of the cities are trapped in the dilemma of garbage siege. So far, garbage in many cities is still piled up in exposed locations without any protective measures. Mosquitoes and flies, rats and mice are infested, and the odor is overwhelming. A large amount of garbage and sewage seeps into the ground from the surface, causing damage to the atmosphere, soil, and water environment. Great pollution, serious harm to human health. [0003] The odor of garbage is caused by the decomposition of organic components in the garbage by bacteria. 75-80% of the domestic garbage is organic matter, mainly including peels, vegetable stems, leftove...

Problems solved by technology

Most of these methods have the disadvantages of high investment, huge equipment required, difficult operation, complicated process, etc., and it is difficult to be widely used in the actual deodorization process.

At present, researchers have begun to study the method of microbial filtration to remove odorous substances, but the removal rate of odorous substances in the currently disclosed methods is low, and the investment and operation costs are relatively high, and it is not suitable for large-scale promotion.
