Biological deodorization technology is to convert harmful substances in organic waste gas into simple inorganic substances, such as C02, H20 and other simple inorganic substances. This is a harmless method of organic waste gas treatment. In practice, bio-decontamination methods use the vital activities of microorganisms to convert harmful substances in exhaust gases into simple inorganic substances (such as carbon dioxide and water) and cellular matter. The main processes include bio-cleaning, biofiltration, and biotrickling.
Credit Suisse Environmental Services Tel+V has its own effective bio-decontamination system for gaseous pollutants with different compositions, concentrations and gas volumes. The biological cleaning tower is suitable for treating waste gas with small gas purification capacity, large concentration, solubility and low biological metabolic rate; The biofilter bed can be used for exhaust gases with large gas volume and low concentration; The biotrickling filter bed is suitable for exhaust gases with high load and acidic substances after pollutant degradation.
Under normal circumstances, the complete process of biological treatment of organic waste gas includes three basic steps: the organic pollutants in the organic waste gas are first connected to the water and can be quickly dissolved in the water; The organic matter dissolved in the liquid membrane gradually diffuses into the biofilm at low liquid concentrations, and is then absorbed by the microorganisms attached to the biofilm; The organic waste gas absorbed by microorganisms will be degraded in their own physiological and metabolic processes and converted into compounds that are not harmful to the environment.
The odorous gas is collected through the pipeline and then enters the biological filtration and deodorization installation. The airflow and circulating fluid complete three processes in the process of passing through the biological packing layer: gas-liquid diffusion, liquid-solid diffusion, and biological oxidation. The microorganisms in the biofilm on the surface of the biological filler are nourished by the odorous gas, and the odor and volatile organic compounds are oxidized and synthesized by the microorganisms, and the energy is generated in the transformation process to provide energy for the growth and reproduction of microorganisms, and the conversion of the odorous gas substances is continuously stopped, and the purified gas is discharged by the induced draft fan.
The biological filter deodorization equipment is to oxidize and decompose macromolecules or organic matter with complex structure into simple water, carbon dioxide and other inorganic substances through effective deodorization bacteria and reasonable equipment structure. Compared to peer equipment, the biological deodorization filter uses pretreatment and biological treatment. The deep adsorption integrated treatment process ensures the stability of the inlet air in the biological treatment stage. At the same time, in-depth processing is configured for no reason. When the exhaust gas emission exceeds the design emission concentration, the exhaust gas emission can be guaranteed to meet the standard.
The role and application of biological deodorization equipment Microbial deodorization process is a reliable deodorization method, with a deodorization efficiency of more than 90%. The basic principle is to absorb, digest, absorb and dissolve foul-smelling chemicals using biological deodorization equipment based on a wet, porous structure and a sand filter filled with specific microbial strains. Microbial strains have small somatic cells, large area, strong adsorption capacity, and diverse metabolic varieties, and are converted into carbon dioxide, H2O, H2SO4, and simple inorganic compounds such as Hno3 after absorbing odorous chemicals. Biological deodorization equipment is the most scientific research and mature technology is the most common method to solve the odorous gas. The solution is for vapors containing odorous chemicals to be dusted, humidified, or cooled and then passed from the bottom of the filter bed from the bottom up. According to the migration of odorous chemicals in the sand filter tank from the liquid phase to the mixed phase (microbial layer) of water-microbial strains, they are decomposed by the metabolic action of microbial strains that adhere to and grow on the filter material. The key to this approach is to harness the cellular biological effects of microbial cultures to dissolve air pollutants and convert them into harmless chemicals.
Peculiar smell of chemical substances O2 Microbial strains Somatic cellular compounds CO2 Ho2 Odorous gases not only cause serious harm to ecological and environmental protection, but also cause great harm to health. The key to microbial deodorization is the use of microbial cultures. According to the basic metabolic effect of microbial strains attached to the tubular reactor packing, manufacturers of biological deodorization equipment convert air pollutants in organic exhaust gases into simple inorganic compounds and microbial strain cytoplasm. Microbial exhaust gas purification equipment converts odorous chemicals in many ways. The main parameters of the biological deodorization equipment are to reasonably dissolve and remove the overall target air pollutants, beyond the purpose of foul odor. Liquid digestion and absorption and microbial solutions are components of the microbial deodorization process. The microbial deodorization process uses liquid digestion and absorption and microbial solutions. The odor is first screened, digested and absorbed by the liquid (adsorbent) to produce mixed wastewater. Microbial exhaust gas purification equipment insulates and then dissolves air pollutants according to the action of microbial strains.
The reclaimed water after advanced wastewater treatment can meet the water quality needs of industry, agriculture and urban landscape. As an effective way to alleviate the water panic in water-scarce areas, the reuse of reclaimed water has been widely concerned. At present, the reclaimed water under the biological deodorization equipment has been widely used in Beijing, Tianjin and other cities. Reclaimed water reuse projects are also being prepared and established, and various investment entities, including ** and enterprises, have also begun to increase capital investment.
On the road to wastewater reuse, the key shift is from the independent application of a single technology to the integrated application of various technologies. In the past, processes were designed to meet emission standards. Now, in order to adjust the integrated application of water, there is an urgent need to stop the integrated integration of existing technologies to meet the stated purpose of water resources.
Biological deodorization equipmentBiological deodorization equipment water system should not only meet the water quality standards, but also combine the overall economical and effective treatment process. The final requirements for wastewater will be organically aligned with each other to ensure a safe water supply at an economically reasonable cost. The reclaimed water treatment process of different biological deodorization equipment can meet different reclaimed water quality requirements.
