Biological filter deodorization tower in sewage treatment plant

Biological filter deodorization tower in sewage treatment plant(Deodorization box, deodorization device, deodorization equipment) The biological filter deodorization tower of the sewage plant uses microorganisms for deodorization. The odor is degraded by microorganisms and then dissolved into water. And the odorous components in the water will be adsorbed and absorbed by the microorganisms in the biological filter deodorization tower of the sewage treatment plant. Then, the odorous components that enter the microbial cells can be decomposed and utilized by microorganisms as nutrients.
Deodorization process of biological filter deodorization tower in sewage treatment plant:
The entire biological filtration deodorization system mainly consists of a pipeline transportation system, a biological filter, a discharge system, and a control system that assists the entire deodorization system,
The gas enters the pre washing tank through the collection pipeline, and after pre washing and adjusting the temperature and humidity, it enters the biological filter deodorization tower of the sewage treatment plant. The treated gas that meets the standards is centrally discharged. At the same time, an axial flow fan is used in the first section of the leachate regulating tank to prevent fresh air from being supplied to the tank, ensuring air circulation and replacement inside the tank. The pre washing tank of the biological filter deodorization tower in the sewage treatment plant consists of an intake distribution room, a washing tank body, a Bao'er ring packing material, a spray system, a circulating water tank, a tail gas collection room, a circulating water pump, and other parts. The odor sucked in enters the distribution chamber, and after being distributed, it enters the washing tank body. The odor is sent from the bottom of the tank, distributed by the gas distributor, and undergoes mass transfer with the spray liquid on the surface of the packing under continuous and sufficient contact conditions in reverse flow. The packing layer in the tank serves as a medium for gas-liquid two-phase contact, and the bottom is equipped with a packing support plate. The packing is stacked on the support plate in a disordered manner. The spray liquid is sprayed onto the packing from the top of the pool through the liquid distributor and flows down along the surface of the packing. Odor can be washed and sprayed with water to remove dust, NH3, as well as a small amount of H2S, CH3SH and other gases from the odor. Ammonia dissolves in water to form an alkaline solution, and circulating spraying can remove H2S from the odor while absorbing a small amount of organic odor pollutants. Monitoring windows and maintenance manholes are installed on the spray washing pool of the biological filter deodorization tower in the sewage treatment plant to facilitate personnel monitoring the normal working condition of the washing tower and timely replacement of aging fillers. In order to avoid the entrainment of liquid droplets in exhaust emissions, a gas water separator is installed at the top of the deodorization tower of the biological filter in the sewage treatment plant. The spray liquid in the pool is circulated for use, and there may be some loss and consumption during use, requiring regular replacement of the spray liquid. The biological filter deodorization tower spray pool of the sewage treatment plant can also flexibly add or replace chemical absorbents according to actual working conditions, but attention must be paid to the secondary pollution caused by chemical wastewater.
Microbial deodorization is a process that utilizes the adsorption, absorption, and degradation functions of microbial cells to treat odors. The main process is as follows: Through the collection pipeline and exhaust fan, the odor is collected into the biological filter deodorization tower of the sewage treatment plant. After being humidified by a humidifier, the odor enters the biological filter body and is then adsorbed, absorbed, and degraded by microbial fillers to remove the odor components.
Biological filter deodorization tower in sewage treatment plantThe deodorization form adopts a first stage water washing and second stage biological filtration. The biological filtration tank body is made of corrosion-resistant fiberglass material, and the biological filtration tank adopts a double inlet and double exhaust form.
