1, the atmospheric dilution method is the odor through the smokestacks discharged to the high atmosphere, in the process, a large number of odor has been adsorbed, greatly reducing the emission of harmful gases in the atmosphere. This method of atmospheric dilution and diffusion to ensure that the downwind residents are not affected, treatment is simple, low economic costs and high efficiency, but the method will still emit a certain amount of harmful gases, only for deodorization of lower concentrations, urban populated areas are not recommended to use this method.
2, activated carbon adsorption method refers to the use of activated carbon adsorption of odor substances, so that odor substances are "retained", but the adsorption capacity of activated carbon is limited, when the adsorption of odor substances enough to reach saturation will need to be regenerated or replaced charcoal adsorption to achieve deodorization purposes.
Activated carbon adsorption method compared to the atmospheric dilution method of poor economic efficiency, requires a lot of human and material resources, but the method of VOC removal capacity is very strong, it is often mixed with other methods used for deodorization.
