In order to ensure human health and safety and reduce harm to the environment, the purification of malodorous gases has become an urgent practical problem to be solved.
The existing malodorous gas treatment technology comprises biological treatment, adsorption, absorption, catalysis, incineration treatment and the like. The principles of different processing techniques are different and each has its application range and advantages and disadvantages. For example, the combustion method has the advantages of being slightly influenced by the properties of pollutants and having high treatment efficiency, but secondary pollution is generated in the combustion process, and the separation and recovery of target substances cannot be realized. The biological method has the characteristics of low cost and mild operation conditions, but has poor adaptability to the working conditions with severe odor concentration change, and cannot recycle the target object. The advanced oxidation method has the advantages of high reaction rate, mild reaction conditions, simple operation, safety and reliability, but the method can generate secondary pollution of oxides and cannot realize separation and recovery of target substances. The plant liquid deodorization method has the advantages of simple operation, quick response and wide application range, but the plant liquid separation and purification process is complex, the safety of the product formed by the plant liquid separation and purification process and the malodorous gas is unknown, and the separation and recovery of the target substance cannot be realized. The absorption method has mature technology and simple process, but the absorbed waste liquid needs secondary treatment and can not realize the separation and recovery of target substances. The adsorption method has the advantages that the adsorbent can be regenerated, the separation and the recovery of target substances can be realized, but the selective adsorption is usually chemical adsorption, and the energy consumption is large.
