Among the conventional odor treatment methods, general chemical treatment methods are mainly used for neutralization of acid-basic odor-inducing substances or two-stage absorption treatment of main odor substances which are easily dissolved in water such as NH ₃ and H ₂ S depending on the oxidation method The absorption power is weak, the neutral odorous substances and the remaining unreacted substances are not sufficiently treated, and thus the emission limit is not satisfied.

In order to solve these problems, there is currently a method of treating odors, namely, an absorption method in which odor is absorbed using an acid / alkali neutralization reaction, an adsorption method in which an odor is adsorbed using an adsorbent such as activated carbon-zeolite, (4) a bio-filter method for decomposing organic substances in the odor by propagating the microorganisms on the carrier, and (4) a method of burning the gas.

Here, although the absorption method can achieve a high absorption efficiency, there is a limit in which the concentration of the odor due to the long-time use of the absorption liquid is rather weighted, and the adsorption method has many difficulties in management and operation with a decrease in efficiency due to high humidity, The incineration method has a limitation that is mainly used as a high concentration and small-scale preventive facility due to the excessive risk of management and installation operation cost. Bio-filter method is not easy to control the temperature and humidity in the four seasons, , The microbial growth on the carrier and the reduction of the carrier volume due to the internal oxidation of the carrier, the increase of the pressure loss due to the closure phenomenon, the microbial activation, the decrease in the efficiency in the recovery period and the carrier change.

However, in the prior arts 1 to 3, it is difficult to remove the odor components contained in the waste gas by collecting the acid and alkali aqueous solution collectively through the single pack tower, and the odor components can not be removed by the single pack tower alone There is a limit.

Korean Patent Registration No. 10-1146831, "Multi-Stacked Multi-Pack Tower", which is a conventional technology 4, implements a pack tower of a single structure in which a solvent tank is formed separately, Layered structure type multi-pack tower in which an aqueous solution such as an alkaline solution is provided, and the aqueous solutions are collected in respective solvent tanks through different paths and circulated, thereby stabilizing the odor components in stages to control activity .

However, according to the conventional technique 4, odor components contained in the waste gas can be removed through a single pack tower by collecting the acid and alkali aqueous solution collectively, but depending on the existing acid and alkali chemical solution processing methods, The odor of the organic polymer series, which has relatively low solubility in water, has a limitation in that it is impossible to apply the finishing treatment applied addition reaction at the final stage by the type of odor and concentration.
