Description

Automatic fresh air deodorization system of sewage case

Technical Field

The utility model relates to a deodorization technical field, concretely relates to automatic fresh air deodorization system of sewage case.

Background

The majority of malodorous substances generated in the sewage treatment process are organic compounds, mainly composed of carbon, nitrogen and sulfur elements, such as low molecular fatty acid, amines, ethers, alkyl halides, aliphatic, aromatic and heterocyclic nitrogen or sulfide. These materials all have reactive groups and are susceptible to chemical reaction and oxidation.

Current methods for deodorizing sewage are roughly classified into chemical deodorization methods, biological deodorization methods, and ion deodorization methods;

the chemical deodorization method generally utilizes the irreversible chemical reaction between the odor components and the main components of the chemical liquid medicine to generate new odorless substances so as to achieve the aim of deodorization.

The biological deodorization method is a process of degrading or converting organic pollutants in odorous gas into harmless or low-harmful substances by using microorganisms.

The ion deodorization method generally generates a coagulation effect of particle charges after ions collide with tiny solid particles in air, so that tiny particles which cannot be captured by a traditional filtering mode and are harmful to human bodies can be captured or settled by self gravity, and the purpose of purifying air is achieved.

However, in the existing chemical deodorization method, corresponding chemical agents are required to be selected due to different odor components, so that the targeted chemical agents are difficult to select, and biological deodorization and ion deodorization are quite high in cost and are not beneficial to large-scale deodorization of sewage plants.
