Problems solved by technology

However, in the existing technology, it is difficult to find bacteria agents with reasonable compatibility and good effect. Most of the bacteria agents cannot be symbiotically promoted, resulting in poor deodorizing effect and failing to meet people's requirements.

Abstract

The invention belongs to the technical field of microbes, and discloses a microbial preparation for removing hydrogen sulfide malodorous substances, which includes the following raw material bacteria: Burkholderia allium, Enterococcus faecalis, Acidophilus ferrooxidans, Candida albicans, Pseudomonas fluorescens, Cellulomonas moist. The bacterial strains in the microbial preparation of the invention are reasonably compatible, symbiotically coordinated, non-antagonistic, high in activity, and can effectively treat sulfur-containing malodorous substances such as hydrogen sulfide.

Description

technical field [0001] The invention belongs to the technical field of microorganisms, in particular to a microbial preparation for removing hydrogen sulfide malodorous substances. Background technique [0002] With the development of economy and the improvement of people's living standards, stench has been paid more and more attention as one of the environmental hazards. In sewage treatment plants, many industries, agricultural production and domestic waste dumps, a large amount of unpleasant exhaust gas will be produced, and the main odor-causing components are sulfur compounds. These substances have a wide range of sources and are extremely toxic, among which hydrogen sulfide is the most common and has the widest impact. [0003] There are many hydrogen sulfide removal methods, which can be simply divided into wet desulfurization, dry desulfurization and biological desulfurization. Wet desulfurization is a method of removing hydrogen sulfide by reacting specific solvent...
