Problems solved by technology

The disadvantages of this patent application are: due to the need to mix and ferment plant extracts and microbial strains in the preparation process, the process is complex, the equipment is expensive, and the preparation cycle is long, resulting in high prices for the biological deodorant produced. At the same time, the existing biological deodorant Odor, the deodorization time is longer, generally takes about 60h; for NH 3 and H 2 The removal rates of S are low, about 80% and 70% respectively

Abstract

The invention discloses a biological deodourant and a preparation method thereof, and belongs to the technical field of environmental protection. The biological deodourant is formed by mixing yeast liquid, spore bacteria liquid, lactic acid bacteria liquid, photosynthetic bacterial liquid and active enzyme liquid according to the mass ratio of (1-1.5):(1-1.5):(1-1.5):(0.05-0.07):(0.001-0.005); plant extraction liquid also can be added according to requirements; after the biological deodourant is used, antioxidants are generated within a short time; survival and reproduction of saprophytes arerestrained; a biological decomposition layer is formed on the surface of dirt; therefore, gaseous NH<3> cannot escape; microorganisms in the biological decomposition layer also can decompose harmful ingredients; the rapid deodorization effect is achieved; after pollutants are eaten, the microorganisms are decomposed into carbon dioxide, water and nontoxic cell debris; no secondary pollution exists; pungent smell cannot be generated in a use process; the biological deodourant can be in contact with the skin of a human body or an animal; furthermore, the biological deodourant is nonhazardous; and thus, the biological deodourant does not need to be cleaned specially.

Description

technical field [0001] The invention relates to the technical field of environmental protection, in particular to a biological deodorant and a preparation method thereof. Background technique [0002] Urban water body is an important part of the urban human settlement environment, but due to its characteristics of easy pollution, small water environment capacity, and poor self-purification ability of water body, it is easy to become the receiver of domestic sewage, rainwater and garbage for residents, thus forming urban black water. Smelly body of water. During the process of domestic sewage generation to sewage treatment facilities for treatment, it often requires the process of collection, standing, temporary storage, and transportation. In this process, once the time is long and the temperature rises, it is easy to produce ammonia gas, The malodorous gas with hydrogen sulfide as the main component has adverse effects on the environment. To deal with this situation in the...
