With the continuous development of the field of pharmacology, pharmaceutical and chemical enterprises are also growing, and the consequent pollution of the pharmaceutical and chemical industry is also becoming more and more serious. Medical sewage station sewage treatment process will emit malodorous gases, these gases seriously affect the normal life of the residents. Explore the medical sewage waste gas treatment process is imminent. Then the specific medical sewage waste gas treatment process which are several?
Adsorption
The principle of adsorption is the use of porous media to adsorb odor molecules. Including physical adsorption and chemical adsorption, it can adsorb low concentrations of malodorous gases. But when the gas concentration is high, the effect of odor treatment will be greatly discounted.
Combustion method
The principle of combustion method is the medical waste gas in the malodorous substances are mostly combustible components, combustion decomposition into harmless water and CO2 and other inorganic substances. But the organic waste gas ignition temperature is generally between 100 ~ 720 ℃, often need to add auxiliary fuel to continuous combustion.
Ozone method
Ozone method is the use of ozone to oxidize organic waste gas, so as to achieve the purpose of deodorization. The method has a certain deodorizing effect and sterilization effect, but the deodorizing effect is poor for the environment where the odor is continuously generated.
Biological method
Biological method is biological degradation of odor components to achieve the effect of deodorization. Biological method because it is the use of biological strains of bacteria to absorb the exhaust gas, for different concentrations of exhaust gas, have very good results, in the biodegradation process, the metabolites will be converted into biological strains of nutrients, do not need to add other additional auxiliary materials, you can continue to deal with the odor.
All of the above are our common medical wastewater waste gas treatment process, at present, it seems that among the medical wastewater treatment equipment, the biological method has a higher overall score, is a very good choice.
