。[Problems to be Solved by the Invention] The water washing method described above has the disadvantage that the deodorizing effect is not sufficient, and the chemical absorption method and direct combustion method require the use of chemicals and fuel in order to maintain the deodorizing effect at high efficiency. Furthermore, in the case of chemical cleaning as shown in Figure 3, since acids and alkalis are used, treatment towers and fillers made of highly corrosion-resistant materials are required, and some of the chemical liquid is discharged. Therefore, the discharged liquid may cause secondary pollution. Furthermore, although the combustion method has an excellent deodorizing effect, there is a risk of secondary pollution since nitrogen oxides, sulfur oxides, chlorine compounds containing chlorine, etc. are generated after combustion.

Powdered or pelleted humus is appropriately supplied into the sludge tank from the outside. In the sludge tank, sludge matures and becomes activated by the growth of soil bacteria in the humus. The accumulated sludge from the sludge tank is supplied to the gas treatment tower, and conversely, the sludge is returned to the sludge tank from the gas treatment tower. Note that the humic plants mix and come into contact with sludge, and soil bacteria in the sludge produce metabolic products. Its metabolites include aerobic bacteria, facultative anaerobic bacteria,
Alternatively, it is a secretion of a bacterial group consisting of aerobic bacteria and facultative anaerobic bacteria, and has an odor-removing component. Activated sludge is stored in a gas treatment tower, and the odorous gas introduced into the gas treatment tower contacts the sludge and undergoes a polycondensation reaction with the odor components in the gas, resulting in volatile odor components. This method increases the molecular weight of the chemical substance, immobilizes it in a non-volatile state, and decomposes it to prevent odor components from escaping, thereby deodorizing the substance.

泥槽３とガス処理塔２との間で循環される。Fresh sludge is supplied into the sludge tank 3 from a treatment facility (not shown), and the sludge is further sent to the reactor 4 and mixed with the humic plants 1 in the reactor 4. In the reactor 4, the sludge matures and the humus is activated by the action of soil bacteria contained in the humic plant i. The humus-activated sludge is returned from the reactor 4 to the sludge tank 3 by opening the on-off valve 12 at regular time intervals. The activated sludge 1] in the sludge tank 3 is supplied into the gas treatment tower 2 from the circulation pipe 8 and the supply pipe 2c by the circulation pump 9. The sludge supplied into the gas treatment tower 2 is first stored on the top shelf 5a, and the overflowing sludge flows from the overflow pipe 7 onto the second shelf 5b and is deposited on the shelf 5b. stored. The sludge that overflows the shelf board 5b similarly flows down and is stored on the shelf board 5c, and the overflowing sludge flows from the overflow pipe 7 to the bottom of the gas treatment tower 2, and passes through the circulation pipe 8 from the discharge port 2d. and return to sludge tank 3. In this way, the sludge is circulated between the sludge tank 3 and the gas treatment tower 2.

It passes through the mist separator 13 and is discharged from the odor port 2b. In addition,
Cleaning water is periodically injected from the water pipe 14 to clean the inside of the mist separator 13 and the gas treatment tower 2.

を分解除去させるものである。The odor bag method is based on a three-point comparison method, and in the deodorizing device I, the humic-activated sludge is used as a deodorizing medium as described above, and the humic plant I is mixed with the sludge. This causes the soil bacteria in the sludge to produce metabolic products. As mentioned above, this metabolite is a secretion of aerobic bacteria, facultative anaerobic bacteria, or a bacterial group consisting of aerobic bacteria and facultative anaerobic bacteria, and decomposes and removes the odor components in the odor gas d. It is something that makes you

し更に分解して臭の発散を防止するものである。For this reason, when the humus-activated sludge comes into contact with the odor components made of organic matter in the odor gas d, it causes a polycondensation reaction and becomes polymerized, increasing the molecular weight of the volatile components that are the main source of odor. It fixes the odor components in a non-volatile state and further decomposes them to prevent the release of odors.

またガス分析はガスクロマトグラフによるものである。By the way, in the above embodiment, the activated sludge is supplied from the reactor 4 to the sludge tank 3, but instead of using the reactor 4, the operator can feed powdered or pelleted corrosives as needed. Alternatively, the sludge may be supplied to the sludge tank 3. In addition, instead of the shelf plate 5 in the gas treatment tower 2, a filler Z is used. Gas analysis is performed using a gas chromatograph.
