摘要： PROBLEM TO BE SOLVED: To exhibit excellent deodorizing effect even when concn. of odor ingredients is remarkably changed by providing at least two stages of treating towers filled with microorganisms and/or an adsorption material and providing a treating tower filled with a porous body exhibiting oxidative decomposition performance to the odor ingredients between arbitrary treating towers. SOLUTION: When odors of waste water treatment contg. an odor ingredient (A) contg. hydrogen sulfide, etc., being easily decomposable under oxidative atmosphere and an odor ingredient (B) contg. other ingredients such as dimethyl sulfide are removed in an deodorizing apparatus, an deodorizing apparatus wherein at least two stages of treating towers filled with microorganisms and/or an adsorption material is utilized. Then, at first, the odor ingredient (A) is removed under oxidative atmosphere in a treating tower filled with a microorganism acting specifically to this. Thereafter, after remaining odor ingredient (A) which has not been removed in the treating tower is removed in a treating tower in which a porous body exhibiting oxidative decomposition catalyst performance to this is filled, other odor ingredients (B) are removed in a treating tower filled with a microorganism acting specifically to them.

摘要： PURPOSE:To provide a porous packing for a deodorizer having an extremely high compressive strength and an extremely low pressure drop when packed in a deodorization tank and capable of sufficiently growing microorganisms. CONSTITUTION:This porous packing is used for a deodorizer for a microorganism growth bed imparting a growth environment to the microorganisms having a malodorous material decomposing function and immobilizing the microorganisms. The packing consists of the material obtained by carbonizing the raw coal consisting essentially of caking coal at 1000-1300 deg.C to release the volatile component in the coal. The packing 8 obtained by crushing the carbonized material has 5-50mm average grain diameter, contains 80-90wt.% fixed carbon and 5-20wt.% ash and has many micropores 82 having 50-500mum inner diameter. Such a porous packing is packed in a deodorization tank to form the deodorizer.

摘要： PROBLEM TO BE SOLVED: To increase sufficiently the immobilized amt. of microorganisms and to improve deodorizing ability by using an aggregate produced by aggregating microorganisms and decomposing and deodorizing an odorous component by the microorganisms. SOLUTION: An aggregate which aggregates microorganisms previously, is produced and for example, by charging it into a packed layer 5 of a biodeodorizing device 1, the sticking amt. of microorganisms on a carrier 6 can be increased. To aggregate the microorganisms, a flocculant is used because the aggregate having strong bonding force can be easily produced and moreover, the size of flock can be easily controlled according to the kinds of the carrier and the microorganisms. Since the microorganisms are electrified into negative charges in the soln. in which the microorganisms are dispersed, the microorganisms are electrically neutralized by using the flocculant and the aggregate of the microorganisms can be formed by van der Waals' force. Thus, the sticking amt. of the microorganisms on the carrier 6 can be increased and the deodorizing ability can be largely improved.

摘要： PURPOSE: To provide the reaction vessel by which waste water treatment can continuously and stably be performed over a long period and also, the initial cost and running cost of which are low. CONSTITUTION: This reaction vessel 1 consists of an anaerobic tank 2 for receiving waste water that is at first allowed to flow from a sedimentation tank into the tank 2 and an aerobic tank 4 for receiving the treated water that is treated in the tank 2 and allowed to flow into the tank 4. In this vessel 1, when a coarse gas hole diffuser 5 that consists of polyvinyl chloride tubes having gas holes 5a, each of which has a 2 to 8mm diameter and which are arranged at a pitch of 100 to 1,000mm, is placed at the bottom of the anaerobic tank 2, the amount of dissolved oxygen in the waste water is reduced to about 0mg/liter and the oxidation-reduction potential(ORP) value is maintained within the range of -200 to 300mV. Since clogging of the coarse gas hole diffuser 5 is inhibited from occurring, the waste water can stably be treated over a long period and also, since this reaction vessel 1 has no moving part and the need of overhauling the reaction vessel 1 is eliminated, the running cost of the reaction vessel can be reduced to a lower value.

摘要： PURPOSE: To make a deodorizing device compact and also to enhance economicity by packing a combination type carrier group and an entrapping type carrier group separately by the group into a carrier packed bed. CONSTITUTION: A carrier packed bed 2 at the gas inlet 1i side of a biological deodorization tower 1 is packed with a combination type carrier group 6 consisting of many combination type carriers 6a using a porous carbon carrier, and also a carrier packed bed 2 at the gas outlet 1o side thereof is packed with an entrapping type carrier group 7 consisting of entrapping type carriers 7a using a PVA gel carrier. Odorous gas containing hydrogen sulfide and methyl sulfide is fed from a gas inlet 1i, and also water is sprinkled onto the combination type carrier group 6 and the entrapping type carrier group 7 from srpinklers 4, 4. In this way, an easily decomposable malodorous material such as hydrogen sulfide and ammonia is decomposed by the combination type carrier group 6, and on the other hand, a difficultly decomposable malodorous material is continued to be decomposed by the entrapping type carrier group 7, allowing various odorous materials to be stably decomposed and removed.
