The bioreactor needs to add aeration equipment, and control temperature and pH conditions to ensure a good state of microbial operation. Advantages: less equipment, lower pressure, less clogging of fillers, easy conditioning of PH, suitable for treating pollutants with acidic metabolic products. Disadvantages: the filler has small surface area, high operation cost, and is not suitable for treating compounds with poor water solubility. 3. Biological trickling filtration Biological trickling filtration is a combination of biological absorption and biological filtration. The absorption and degradation of pollutants occur simultaneously in one reverberator. The filler in the container is generally gravel, ceramics, polypropylene beads, granular activated carbon and other materials with a larger surface area, which acts as a carrier for microbial growth.

Due to the high wind speed, the air duct of the dedusting system is generally round with small diameter. However, in order to avoid air duct blockage, the diameter of dedusting air duct should not be less than the following data; Small dust (mineral dust) 80mm; coarse dust (such as wood chips) 100mm; coarse dust (such as wood chips) 130mm; wood chips 150mm 4. The air duct of the dust removal system requires good hydraulic balance. For hydraulic calculation of parallel pipeline, general ventilation system.

Air and waste gas purification in spice workshop, cosmetics workshop and food workshop: methyl methacrylate, ethyl acetate, ethyl acetoacetate, aldehydes, ammonia, trimethylamine, hydrogen sulfide and methyl methacrylate Waste gas treatment company Mercaptan, methyl sulfide, dimethyl disulfide, etc; 3. Air and waste gas purification of petrochemical plants: sulfur dioxide, nitrogen oxides, smoke, benzopyrene, non-A company company Alkane hydrocarbon, hydrogen sulfide, evaporated phenol, amine, hydrocarbon, benzene, acrylonitrile, cyclohexane, ammonia, ethylene, styrene, butadiene, propylene, vinyl chloride, etc; 4. Waste gas treatment of iron and steel plants and steelmaking plants: sulfur dioxide, carbon dioxide, carbon monoxide, hydrogen fluoride, some evaporative organic matter, smoke and dust; 5. Air and waste gas purification of printing workshop: benzene waste gas treatment, toluene waste gas treatment, xylene waste gas treatment; Butyl acetate, non methane hydrocarbon, etc.

Then it enters the UV photolysis purification equipment to remove the odor gas organic waste gas, and uses the high-energy UV light beam to differentiate the oxygen molecules in the air to produce free oxygen (i.e., active oxygen). Because the free oxygen carries the imbalance of positive and negative electrons, it needs to combine with the oxygen molecules, and then ozone occurs. The ozone has a strong oxidizability, and through ozone, the organic waste gas The malodorous gas undergoes synergistic photolysis and oxidation to degrade and transform organic waste gas and malodorous gas into low molecular compound, water and carbon dioxide. (3) The induced draft fan makes the front system under negative pressure.

Previously, activated carbon adsorption was selected for rubber vulcanization waste gas, and the main treatment fields include: production of electronic components, production of batteries (batteries), pickling workshop, laboratory exhaust, metallurgy, chemical plants, pharmaceutical manufacturers, coating workshops, food and brewing, furniture production, etc. It is especially suitable for waste gas treatment of rubber vulcanization, foaming and rubber refining processes in rubber industry, tire industry, seal manufacturing enterprises, rubber and plastic industry, etc. The adsorption characteristics of activated carbon are mainly used to adsorb the waste gas of organic solvents such as benzene, alcohol, ketone, ester and gasoline. However, since the activated carbon after full adsorption is a hazardous waste, it needs to find a professional solid waste or hazardous waste treatment unit for treatment, and a hazardous waste treatment agreement needs to be signed. Therefore, activated carbon adsorption has been gradually replaced by other waste gas treatment equipment, Before understanding the rubber vulcanization waste gas treatment equipment, let's first understand in which process the waste gas mainly occurs.

Of course, there are a lot of emissions from the plastic factory. If the substances contained in it can alleviate the surrounding plants, it will certainly affect the surrounding plants, even kill them. 2. Waste gas treatment process of plastic granulation The plastic granulation plant will have nose piercing odor in the production process, and the photolysis purification equipment has a significant role in deodorization, so this equipment is widely used in various industries that will need deodorization. Hydrogen chloride, methyl methacrylate, styrene and other components in the exhaust gas are differentiated by the high-energy and high ozone ultraviolet beam, and then oxidized with ozone, so that the odor gas substances can be degraded into low molecular compounds, water and carbon dioxide, and then discharged into the atmosphere through the exhaust duct.
