Fiberglass biological filtration tower, garbage station biological deodorization equipment

Fiberglass biological filtration tower and garbage station biological deodorization equipment are environmentally friendly devices that use biological fillers as carriers to allow microorganisms to form biofilms on the surface of biological fillers in suitable environments. The microorganisms in the biofilms use inorganic and organic substances in exhaust gas as carbon sources and energy sources to maintain their life activities by degrading odorous substances, and decomposing odorous substances into odorless substances such as carbon dioxide, water, minerals, etc., achieving the goal of purifying odorous gases.

>>Technical principle of biological deodorization equipment

Biological deodorization technology utilizes the physiological processes of microorganisms to convert harmful substances in organic waste gas into simple inorganic substances, such as CO2, H2O, and other simple inorganic substances. This is a harmless organic waste gas treatment method.

>>Process flow

Odor gas collection device → pretreatment device → biological deodorization equipment → exhaust fan → standard emission

>>Process description

The odorous gas is collected through pipelines and enters the pre-treatment device. After being washed and humidified, the humidity of the exhaust gas reaches over 90%. The wet gas then enters the biological filtration and deodorization device. The airflow and circulating liquid complete three processes of biological gas-liquid diffusion, liquid-solid diffusion, and biological oxidation during the process of passing through the biological packing layer. The microorganisms in the biofilm on the surface of the biological packing take the odorous gas substances as nutrients, and the odorous substances and VOCs are oxidized and decomposed by the microorganisms. During the transformation process, energy is generated to provide energy for the growth and reproduction of microorganisms, so that the transformation of odorous gas substances continues. The purified gas is discharged from the induced draft fan.

The circulating liquid contains detached biofilm and microorganisms, which are filtered and replenished with fresh washing solution before being recycled. The excess biofilm is removed by filtration and discharged regularly as sludge.

>>Advantages of biological deodorization device

(1) Fully automatic control, stable performance, no need for dedicated personnel to operate;

(2) By using long-lasting biological fillers, microorganisms can grow by relying on nutrients in the washing solution and odorous substances in the gas, without the need to add additional nutrients. The ecological conditions of biofilm are stable, with a large biomass per unit volume. The microbial community has a high ability for biological adsorption and oxidation, strong shock resistance, and fast and efficient decomposition of odorous substances;

(3) The tower adopts a modular structure, which can be constructed on site and is easy to install;

(4) Unique gas distribution method, uniform distribution, purification efficiency of over 90%.

>>Scope of application of biological deodorization device

The treatment of odorous gases such as hydrogen sulfide, ammonia, mercaptan, and thioether generated during processes such as sewage treatment plants, garbage disposal, feed processing, manure treatment, and pharmaceutical factories.
