Background
With the improvement of the living standard of residents and the change of living concepts, the requirement on the environment is higher and higher, and the odor pollution becomes a serious social and environmental problem increasingly. The malodorous pollution is mainly from factories, and the malodorous gas has complex components and great monitoring difficulty. Common malodorous gases can be classified mainly into 5 types: nitrogen-containing compounds, sulfur-containing compounds, halogenated hydrocarbons, oxygen-containing organics. The conventional malodorous gas treatment methods include washing absorption, biological treatment, photocatalytic oxidation, incineration, activated carbon adsorption, plasma methods and the like.
(1) The washing absorption method mainly utilizes water or solution to dissolve malodorous gas and react with odor molecules, but many malodorous gases are difficult to dissolve in water or solution, the deodorization effect is poor, the equipment maintenance cost is high, and secondary pollution such as waste water or solid waste is generated.
(2) The biological treatment method is mainly characterized in that odorous gas is converted by microbial physiological metabolic activity. Malodorous gases serve as nutrients for microorganisms. The disadvantages are that the microorganism needs to be cultured first, the temperature has a large influence on the microorganism and the occupied area is large.
(3) The photocatalytic oxidation is to activate a catalyst to generate electron hole pairs through ultraviolet irradiation with specific wavelength, then the catalyst reacts with water and oxygen molecules to generate hydroxyl radicals, and then malodorous gas is decomposed, so that the aim of deodorization is fulfilled. But the catalyst is easy to be poisoned and needs to be replaced frequently, causing secondary pollution.
(4) The burning is to mix the foul gas and fuel gas to realize complete burning. But it is suitable for treating a high concentration of a small amount of combustible gas. But the equipment cost is high, the equipment is easy to be corroded and consumed greatly, the occupied area is large, the fuel gas consumption is large, and the operation and maintenance cost is high.
(5) The active carbon adsorption is to transfer the malodorous gas from a gas phase to a solid phase by utilizing the adsorption function of the active carbon to achieve the aim of deodorization. The disadvantages are that the consumption of the adsorbent is large, the regeneration is difficult, the treatment temperature of the waste gas is not too high, and the generated solid waste needs to be treated again.
(6) The plasma method is to utilize an ion reaction leading-in device to generate ions for a main reactor, and particles rich in extremely high chemical activity, such as electrons, ions, free radicals, excited molecules and the like, are generated in the plasma in the dielectric barrier discharge process. The pollutants in the exhaust gas react with the active groups with higher energy and are finally converted into CO2And H2O and the like, thereby achieving the purpose of purifying the waste gas. However, the treatment of flammable and explosive gases has the risk of explosion, the action range of a discharge field is small, and the purification efficiency is low under the conditions of high flow speed and large air volume.
