Embodiment Construction

[0023] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0024] This specific embodiment adopts the following technical solutions: immobilized microbial bacterial agent and preparation method thereof, the steps are:

[0025] (1) Centrifuge the bacterial liquid at a speed of 5000rpm for 30min to obtain concentrated bacterial liquid

[0026] (2) Mix the fermented biomass and the concentrated bacterial liquid evenly to prepare the immobilized microbial bacterial agent.

[0027] (3) Dosing: Evenly add the immobilized microbial agent to the surface of the odor source, and the dosage is 400g / m 2 .

[0028] The air bag experiment was used to simulate the source of odorous pollutants. In a 50cm*70cm ziplock bag (the airtightness inspection has been carried out), the food collected from the school canteen was ...

Abstract

The invention discloses an immobilized microbial agent and a preparation method thereof, and an application of the immobilized microbial agent in highly-efficient deodorization. The preparation methodcomprises the following steps: adding a bacterial liquid or a concentrated bacterial liquid into dry fermented biomass, and carrying out mixing under stirring so as to obtain the immobilized microbial agent. According to the invention, degrading bacteria with highly-efficient removal effect on the odor of a landfill are loaded onto a carrier, namely the fermented biomass, so high concentration ofbacteria is maintained; meanwhile, the survival time of the bacteria can be prolonged; the removal effect of the odor can be improved; and the deodorization of the landfill can be realized. The method provided by the invention has stable effect, does not generate secondary pollution, facilitates transportation, and solves the problems that the effect of deodorization is not lasting and the treatment efficiency of the microbial agent is low. The immobilized microbial agent provided by the invention is highly-efficient and practical, achieves good deodorization effect and improves the working environment.

Description

technical field [0001] The invention relates to the application field of deodorants, in particular to an immobilized microbial agent, its preparation method and application. Background technique [0002] Immobilized microorganism technology is a modern bioengineering technology that uses chemical or physical means and methods to limit or locate free microorganisms in a specific space, retain their inherent catalytic activity, and can be used repeatedly and continuously. [0003] The immobilized microbial agent obtained by the immobilized microbial technology can be applied in the field of landfill deodorization technology due to its advantages of high microbial activity, high microbial density per unit space, good effect and long-lasting effect. [0004] The annual production of municipal solid waste in my country is about 140 million tons, except for a small part of incineration, composting or recycling, more than 80% are transported to landfills for landfill treatment. In...
