For treating malodorous gas such as ammonia and ammonia, treatment techniques such as soil deodorization, biological deodorization, chemical cleaning, and activated carbon adsorption are usually used. These processes are employed alone or in combination. Generally, when the concentration of the malodorous gas is high, the malodorous gas is removed by biological deodorization or chemical cleaning, and when the concentration of the malodorous gas is low, the malodorous gas is removed by activated carbon adsorption.

い。[0003] Activated carbon is generally used as a deodorizing agent for removing odorous gas (for deodorizing). This activated carbon activates charcoal such as coconut shell (by converting high-temperature steam or the like into carbon monoxide gas). Oxidation)
This is one in which minute pores are formed. Activated carbon can adsorb and hold odor components by the action of physical force (van der Waals force) on the surface of the thus formed large pores, internal diffusion into the pores, and capillary condensation.
However, ordinary activated carbon has a low adsorptive power to low molecular weight polar substances such as hydrogen sulfide and ammonia generated in a sewage treatment plant, and cannot exhibit a sufficient deodorizing effect.

果で脱臭を行なうものである。In order to adsorb odorous gas containing an acidic component or an alkaline component, an impregnated activated carbon obtained by impregnating and holding a chemical solution (acid, alkali, etc.) on activated carbon is used. This impregnated activated carbon performs deodorization by an adsorption effect of a chemical reaction (neutralization reaction) between an impregnated substance and an odorous component, in addition to the physical adsorption of the activated carbon.

る。When the impregnation is performed by impregnation, a considerable amount of solution must be prepared in order to immerse the entire activated carbon. Further, it is inevitable that the solution remains after the attachment, which is uneconomical. When the remaining solution is used again for impregnation, it is necessary to readjust the concentration and the amount of the solution because the concentration of the solution has changed. For this purpose, complicated operations such as measurement of the iodic acid concentration, measurement of the hydrochloric acid concentration, and measurement of impurities generated during the attachment operation are required. Moreover, since activated carbon powder is concentrated in the residual liquid, an operation of removing them is also necessary.

混合溶液をスプレー照射する。In the present invention, first, the raw material activated carbon is stored in a rotating container such as a drum, and is stirred while being shaken by being rotated or by using a stirring device (such as a stirrer, a stirring rod, and a stirring blade). While vibrating, an aqueous solution of iodine oxo acid or a mixed solution of iodine oxo acid and inorganic acid is sprayed.

く。When the activated carbon is rotated, it is desired that the activated carbon is not rotated 360 degrees, but is freely pendulum-moved without fixing a shaft instead of a single shaft. Since the activated carbon is freely stirred by rotation, spraying the activated carbon in such a state with a predetermined solution allows iodic acid or iodic acid and inorganic acid to be uniformly and always applied to a new surface of the activated carbon fine particles. Can be attached. In addition, the mixed solution of iodic acid and inorganic acid attached to the surface of the activated carbon particles permeates into the voids inside the activated carbon due to the stirring and mixing caused by the shaking.

４０分程度行なうことが望まれる。The concentration of the aqueous solution of iodine oxoacid used here is preferably about 0.01 to 0.5 mol / L. The concentration of the aqueous solution of iodine oxoacid is 0.
When the amount is less than 01 mol / L, the amount of oxo acid of iodine impregnated on the activated carbon is small, and it is difficult to sufficiently improve the adsorption performance of the activated carbon. On the other hand, 0.5 mol /
If it exceeds L, many of the pores of the activated carbon will be blocked by the oxo acid of iodine, and the adsorbing ability of the activated carbon may be reduced. The spray irradiation of the iodic acid solution onto the activated carbon is performed in order to sufficiently penetrate the iodic acid into the activated carbon micropores.
It is desired to perform for about 40 minutes.

ソ酸の濃度および添着時間は、上述したとおりである。When a mixed solution of iodic acid and an inorganic acid is sprayed on activated carbon, it is desirable to use hydrochloric acid as the inorganic acid. The concentration of the inorganic acid is preferably from 0.1 to 5N, more preferably from 0.5 to 2N. When the concentration is less than 0.1 N, it is difficult to sufficiently exhibit a synergistic effect obtained by impregnating the activated carbon with both the iodine compound and the inorganic acid. On the other hand, if the acid concentration exceeds 2N, the acid concentration may be too high and iodic acid, which is a weak acid, may be decomposed into iodine. In this case, the concentration of the oxo acid of iodine and the time of the application are as described above.

少なすぎる場合には、活性炭に均一に添着することが困
難となる。The amount of the aqueous solution of iodic acid of iodine or the mixed solution of iodic acid and the inorganic acid to be sprayed is preferably such that the amount of voids inside the activated carbon + the surface of the activated carbon particles is wetted. If the amount of the solution to be sprayed is too large, there is a disadvantage that the activated carbon is greatly wetted with water as in the case of the impregnation by impregnation. on the other hand,
If the amount is too small, it will be difficult to uniformly impregnate the activated carbon.

なうことによって補うことができる。The rate of spray irradiation of an aqueous solution of oxo acid of iodine or a mixed solution of iodic acid and an inorganic acid is desirably about the same as or less than the rate of permeation into voids inside activated carbon. Further, the range of spraying such a solution is desirably equal to the range in which the activated carbon is two-dimensionally dispersed and spread, but can be compensated by sufficiently stirring.

It is desirable to promote penetration.

ましい。The activated carbon to which iodic acid or iodic acid and an inorganic acid are impregnated is dried in an atmosphere at 80 to 160 ° C. When the drying treatment temperature is low, the drying treatment takes a long time. On the other hand, when the drying treatment temperature is high, there is a possibility that the attached iodine compound or the like may be disadvantageously desorbed from the activated carbon. In particular, it is preferable to dry at 120 ° C. or less to make the activated carbon after drying have a water content of 5% or less.
