The biological method for purifying and treating volatile organic waste gas is economic, efficient and environment-friendly, and is replacing a physical and chemical method to become a mainstream purification and treatment technology, the working principle of the microbial deodorization technology is the adsorption, absorption and degradation functions of microbial cells on malodorous substances, and the microbes have the characteristics of small cell size, large specific surface area, strong adsorbability and various metabolic types, and can convert the malodorous substances into non-toxic simple inorganic substances such as CO2, H2O, H2SO4, HNO3 and the like after adsorption and absorption.
The biological malodorous gas purifying process is to decompose and oxidize malodorous gas by using biological bacteria, so that the malodorous gas is decomposed into CO2 and H2O and other harmless and odorless gases to be discharged. The biofilter purification devices are generally classified into three main categories according to the properties of biological fillers and the structural form of treatment equipment: namely a soil method (a biological deodorization filter), a biological composting method (a deodorization filter) and a biological deodorization trickling filter.
In the prior art, when waste gas generated by foul substances in sludge and sewage is treated, microorganisms are generally used for deodorizing the waste gas, but in the actual use process, the possibility that the gas flows too much to cause partial gas to be not treated fully is still easy.
