Biological deodorant for sewage deodorization spray tower description processing equipment: biological deodorization is the use of biological methods through special training of biological filter biological deodorization filler microbial membrane waste gas biological waste gas treatment skills. When three types of mixed toxic, harmful, and foul smelling gases, including gas, liquid, and solid, enter the system through the collection pipe, the biofilm is used to purify waste gas and degrade pollutants by cultivating effective microbial strains through the addition of biological fillers. On the one hand, the biofilm of exhaust pollutants is nutritious and increases; On the other hand, the differentiated toxic and harmful exhaust gases and foul smelling substances include carbon dioxide, water, sulfuric acid, nitric acid, and simple inorganic substances, which then achieve the purpose of deodorization. Scope of application: Urban sewage stations (odor, pre-treatment odor, odor sludge treatment); Waste factories (collecting odors, sorting workshops); Deodorants/odors of paint; Waste gas produced by plastic and rubber factories; Feed processing waste gas; Odor of food and beverage factories; Pharmaceutical company deodorants/odors. Its basic feature is to establish microbial growth in the waste gas treatment structure, and under oxygenation conditions, microorganisms gather on the surface of the filler to form a biofilm. When the biofilm of waste gas undergoes microbial differentiation and organic matter absorption, the waste gas is purified, and the microorganisms proliferate together, the biofilm thickens. When the biofilm grows to a certain thickness, the oxygen diffusion inside the biofilm is still under aerobic conditions, and the outer and inner layers are in anaerobic and anaerobic conditions, ultimately leading to the detachment of the biofilm. Afterwards, new biofilm fillers will continue to be developed on the surface and circulated to purify the exhaust gas.

Biological deodorization is the use of microorganisms on the surface of carrier fillers to remove odor under suitable conditions. The odor substance is absorbed and packaged, and then oxidized and differentiated by microorganisms on the attached packaging, completing the odor removal process. In order for microorganisms to maintain high activity, it is necessary to create an outstanding day, such as suitable humidity PH value, temperature, oxygen content, and nutritional composition, etc. The actual production design requires that the carrier's packaging is at 80~95% relative humidity, so spray untreated sewage or pond water is often used to supply water and nutrition. The key point of sewage deodorization packaging lies in the packaging itself, such as the use of packed towers in the process of waste gas treatment, the specific packaging of skills inoculated with specific or microbial substances, the packaging layer of waste gas, absorption of bacteria and microorganisms, or degradation, to achieve the purpose of purification. Therefore, the number of nozzle packing towers is not large, and the main intention is to adhere to humidity, tower temperature, meet the requirements of microbial innovation, the size of tower diameter and the conditions for managing exhaust air volume (pressure loss), and related investment.

In the packing tower of the bioreactor, after the filling (or bottom blowing aeration) of the exhaust gas and the contact stage with the packing, the distance between the biofilm and the two layers of activated sludge packaged on the outer surface of the packaging is used for exhaust gas purification. Biological packing tower, with most microorganisms fixed on the surface of the packing, increases the biofilm, and some suspended activated sludge in water. Therefore, the characteristics of biological towers, activated sludge processes, and biofiltration are a type of biofilm activated sludge process, mainly serving the role of biological treatment processes.

Wastewater deodorization filler is an important part. It is necessary for outstanding carrier packaging to meet the following requirements: allowing for an increase in microbiology; A large surface area that provides habitat for microbial growth; Reasonable nutrition (nitrogen, phosphorus, potassium, and trace elements). Has outstanding water absorption and no odor; Outstanding adsorption; Uniform pore structure, easy and cheap data, anti-aging function; Simple operation and. Commonly used fillers include plastic and soft plastic, dried bark, hay, fiber peat, or their mixtures. The height of packing in the deodorization tower depends on the required time and external load. The packaging height is usually between 1.0 and 1.2 meters in engineering. Packaging, if you choose an airplane, can be made of cloth to eliminate short airflow and achieve a low height of 0.5 meters. The reference value of ozone concentration control

(3) Microorganisms can rely on organic growth in packaging without the need for increased nutrition. Therefore, after shutting down the use of quick start, the outstanding therapeutic effect can be achieved immediately after a weekend shutdown or another week of shutdown, and a few hours later. Immediately discontinuing the operation for 3 to 4 weeks begins to have outstanding therapeutic effects, and within a few days, the therapeutic effect of Kangfujie is remarkable.

Process flow: The biological deodorization process involves three stages of odor: 1. Toxic, harmful, and odorous pollutants come into contact with water and dissolve in water or ions in the liquid phase. This process is a physical process that follows the Henry's law: π =HXi. 2. The odor component is absorbed by microorganisms in the adsorption solution, and the odor component is transferred from the water to the microorganisms in the body. 3. Organic matter enters microbial cells through the catalytic action of enzymes, leading to microbial oxidation and differentiation. Together, microbial cells synthesize and metabolize new substances. Partial oxidation and differentiation of organic matter ultimately result in the stability of water, carbon dioxide, and inorganic matter. Skill features: 1. Biological skills, hygiene, and no secondary pollution. 2. It can include various pollutants and exhaust gases. 3. Strong impact resistance, with fluctuations in exhaust gas concentration between 3-1500 PPM, able to operate normally. 4. Short processing time and high power. The complete power that can be purified in 5-10 seconds can reach over 95%. 5. Film hanging, biological diversity, and short vaccination time. 6. Low construction cost, low operating cost, and no added chemicals. 7. Using fiberglass/stainless steel materials, it has a beautiful appearance, strong corrosion resistance, long service life, composite filtering material, large surface area, outstanding breathability, non hardness, and long service life. On the 9th, PLC control with high degree of automation. 10. Double layered structure, sandwich filled with insulation materials, suitable for operation in cold climates, and equipped with anti-corrosion coating inside. Widely used in chemical, electroplating, metal, electronics, medicine, printing and dyeing, telecommunications, watches, and other mechanical processing industries, nitrogen oxides, sulfur dioxide, sulfuric acid, hydrochloric acid, and high-frequency SIF4 are used to purify toxic and harmful gases such as carbon dioxide; It can also be applied to the deodorization process of ammonia, hydrogen sulfide, phenol phosgene, and odorous substances such as formaldehyde, methanol, and amines.
