How to deodorize the sewage station? Deodorization method for sewage treatment plants

Social development will inevitably produce a large amount of sewage odor, which seriously affects people's daily life and needs to be paid attention to and dealt with by relevant departments. So, what are the types of deodorization processes in sewage stations? How?

Next, I will focus on two common types of sewage station deodorization processes.

Combustion deodorization process.

The principle of combustion deodorization technology is to use the flammability of odorous substances, fully mix odorous substances with fuel gas, and convert odorous substances into odorless substances through combustion, so as to achieve the purpose of deodorization. Combustion deodorization is suitable for the treatment of high concentrations of flammable odorous gases. The advantage of combustion deodorization is that the odorous substances can be completely oxidized and decomposed, and the removal efficiency is high.

However, combustion deodorization requires fuel consumption, high operating costs, and is prone to secondary pollution.

Hello, I am glad to answer for you Here are several common deodorization methods used to sort out sewage treatment plants, I hope they can help you: 1 Collect gas. The gas generated during the treatment process is transported through the pipeline to a closed gas gathering well or chemical chamber, and then processed after collection, which greatly reduces the odor and pollutants in the air.

2 Aeration and deodorization method. In the aeration tank, a large amount of oxygen is injected into the aeration tank through the aeration equipment to accelerate the oxidative decomposition of organic matter and ammonia in the water, so as to remove the foul odor. 3. Activated carbon adsorption method.

The use of activated carbon to adsorb the gases generated during the treatment process can effectively remove pollutants such as odors and VOCs. As the adsorption of polluting gases increases, the activated carbon will gradually become saturated and will need to be replaced regularly. 4 Biological deodorization.

By cultivating an appropriate amount of aerobic or anaerobic microorganisms to degrade harmful odor and bad components, it can effectively remove the exhaust gas and odor in the sewage. 5. Chemical oxidation. Chemicals are used to oxidize and decompose organic matter into harmless water and carbon dioxide, commonly used chemicals such as sodium hypochlorite, ozone, hydrogen peroxide, etc.

This method can achieve a good governance effect, but it has high requirements for equipment and security.

The deodorization method of the sewage treatment plant is as follows:

With the development of society, the problem of deodorization has become increasingly prominent, whether it is corporate deodorization or municipal deodorization, it has attracted more and more attention. The odorous gas treatment technologies commonly used in sewage treatment plants mainly include biological filters, biological trickling filtration, plant extract deodorization, activated carbon adsorption deodorization, high-energy ion deodorization, chemical deodorization and active oxygen deodorization.

Here's how:

1. Deodorization of biological filter.

The biological filter mainly includes two parts: the pre-washing section and the biological section. The odor collected by the induced draft fan is pre-washed in the pre-washing section (part of the pretreatment also includes temperature regulation, particulate matter removal, etc.), and then enters the biological section for the treatment of odor pollutants. The pollutants in the gas diffuse from the main body of the gas phase to the water film on the outer layer of the filler, which is absorbed by the filler and finally degraded into carbon dioxide, water, etc.

The treated gas is discharged from the top of the biofilter. The packing layer of the biological filter is adsorbent filter media (such as soil, compost, activated carbon, etc.).

2. Biological trickling filtration and deodorization.

The body of the trickling filter column is a packed column with one or more layers of packing, the surface of which is a biofilm several millimeters thick formed by microbial flora. The liquid containing the soluble inorganic nutrient solution is evenly sprayed on the packing from the top of the column, and the liquid flows from top to bottom, then discharged from the bottom of the column and recycled. The organic exhaust gas enters the biotrickling filter tower from the bottom of the tower, and is purified by contact with the wetted biofilm during the ascent process, and the purified gas is discharged from the top of the tower.

3.Plant extracts deodorize.

The deodorization mechanism of plant extracts is that the odor molecules in the odor are sprayed and adsorbed by the droplets of plant extracts scattered in the space, and various reactions occur at room temperature to produce odorless and non-toxic molecules. Natural plant extract is a plant deodorant formed by microemulsification of oil, juice, or extract extracted from flowers and trees in nature, which can be completely biodegradable, non-toxic, harmless, non-polluting, can eliminate odor, and can play a role in acidic, alkaline, neutral and other pollutants, and can effectively remove odorous gases.
