The chemical treatment method mainly comprises a combustion method, a photocatalytic decomposition method and the like. The combustion method commonly used at present comprises direct combustion type incineration and regenerative thermal oxidation, the direct combustion method is suitable for occasions where waste heat utilization is needed for waste gas treatment such as automobile body drying chambers, part drying, printing, color coating drying and the like, and the defects of the regenerative thermal oxidation include: a. the one-time investment cost is relatively high, b, the treatment process is required to be operated continuously as much as possible, the method is not suitable for treating the condition of intermittently discharging organic waste gas, c, the dust concentration is required to be controlled to be less than or equal to 40-50 mg/m before the waste gas enters the device 3 Humidity is lower than 70%And the waste gas does not contain acid and alkali gases and oily substances; disadvantages of the photocatalytic decomposition method include: a. mainly applied to lower concentration (generally < 500 mg/m) 3 ) Treatment of organic waste gas, which is not suitable for treatment of waste gas containing substances which are easy to poison catalyst in waste gas, b. compared with other thermal oxidation methods, the removal rate of VOCs in waste gas is relatively low, c. before waste gas enters the device, the dust concentration is required to be less than 4mg/m 3 The temperature is less than 40 ℃, the humidity is less than 40% and no oil substances are contained, otherwise, the ultraviolet lamp is easy to be shielded to influence the treatment effect, most of UV photocatalytic treatment equipment applied to VOCs treatment is based on the technical principle of deodorization and sterilization, generally, a double-wavelength ultraviolet lamp tube is adopted, energy is mainly used for converting ozone, a titanium dioxide material is used as a catalyst, although the decontamination efficiency is more than 80%, the actual use efficiency is low, in practice, the reaction time is too short, and organic matters generate intermediate products with stronger toxicity such as ketone and aldehyde and a large amount of ozone under the photocatalytic effect.
The biological treatment method comprises screening and culturing microorganism with special degradation effect on organic waste gas component, fixing and adhering on porous medium filler surface, biologically treating waste gas in filler bed layer, adsorbing volatile organic pollutant in pores, degrading by microorganism to generate CO 2 、H 2 The biological treatment technology is mainly applicable to industries such as spraying, printing and dyeing, rubber mixing, plastics and the like, the main types of organic waste gas are toluene, dimethylbenzene, non-methane total diameter, esters, alcohols and the like, and the biological treatment technology is generally applicable to the concentration of organic matters of 500mg/m 3 The removal rate of VOCs in the following waste gas can reach 80-95%.
