Problems solved by technology

In recent years, the research work on microbial deodorants has mainly focused on the selection and breeding of highly efficient deodorizing dominant strains. The research on popularization and application mostly uses microbial preparations imported from abroad, mainly Japanese EM bacterial agents, while domestic self-selection and reproduction Research on the formulated microbial deodorant is still rare

Abstract

The invention belongs to the field of environmental protection and particularly discloses aa microbial deodorant for deodorization. The microbial deodorant comprises the active components: a microbial agent, molasses, amino acids and vitamins; the microbial agent is a composite bacterial agent of Kluyveromyces marxianus and Bacillus subtilis; the microbial deodorant is capable of inhibiting the growth of putrefying bacteria, improving the degrading means of organic matters and decreasing the release of ammonia and hydrogen sulfide and occurrence of ammonia matters, and is capable of deceasing methane from bacterial decomposition, thereby arriving at deodorization; the materials of the microbial deodorant are easy to obtain, the preparation method is simple, and the microbial deodorant is worthy of popularization and application.

Description

technical field [0001] The invention belongs to the field of environmental protection, and specifically relates to a microbial bacterial agent for deodorizing biological sewage and an application thereof, especially a microbial bacterial agent suitable for treating stinky domestic sewage. Background technique [0002] With the rapid development of economy and society and the continuous acceleration of urbanization, indoor and outdoor environmental pollution is always becoming more and more prominent. People's attention to environmental pollution has shifted from outdoor to indoor. An important cause of pollution is the massive discharge of urban wastewater. According to According to statistics, the total discharge of urban wastewater in my country is about 34.5 billion tons per year, of which domestic sewage accounts for more than 30%. COD and BOD in domestic sewage 5 Seriously exceeded. A kind of bad smell is emitted in the family bathroom and the kitchen sewer due to vario...
