Problems solved by technology

The research on deodorization technology for malodorous gases began in the 1990s. Now the market uses mainly physical and chemical methods for deodorization. However, physical and chemical methods have high operating costs and produce secondary pollution. So far, there is no ideal solution. Biological deodorization technology and deodorization products can be applied in production practice

Embodiment 1

[0027] The three-layer multi-bacteria biological deodorization filter tower consists of tower body, bottom deodorization layer 5, middle layer deodorization layer 5 and top layer deodorization layer 5, air distribution head 4, air pump 2, water pump 11, water pipe 13, atomizing spray faucet 9. Humidity sensor 8, microcomputer 10 and canopy 15 are formed.

[0028]The tower body is a hollow cylinder with a bottom and no top, with 1 air inlet hole and 3 gas measuring holes 7 on the side, and an air distribution head 4 parallel to the bottom surface is installed at a distance of 20-40 cm from the bottom of the tower body. The head 4 and the bottom of the tower form an air chamber 3, and the air intake hole is in the air chamber 3. The bottom deodorizing layer 5, the middle layer deodorizing layer 5 and the top deodorizing layer parallel to the bottom are installed sequentially above the air distribution head 20 cm. Odor layer 5; the bottom deodorant layer 5 is composed of the bott...

Abstract

The invention discloses a multilayer mixed culture biological deodorizing filter tower and a method for removing malodorous gases, relating to the application of special microorganism culture. The multilayer mixed culture biological deodorizing filter tower comprises a tower body, a plurality of deodorizing layers (5), a gas distributing head (4), a gas pump (2), a water pump (1), a water pipe (13), an atomization water-spraying cock (9), a humidity sensor (8), a microcomputer (10) and a rain shed (15), wherein the tower body is a column body and is internally provided with the deodorizing layers, each deodorizing layer adopts different substrates and different cultures for removing different malodorous materials in the malodorous gases. Because the cultures are layered, functional cultures are not interfered; in addition, because the deodorizing layers are layered, the loss of the pressure of the gas pump is reduced to enable the deodorizing efficiency to be greatly improved and continuously efficient without producing secondary pollution, and the operation cost is low.

Description

technical field [0001] The invention relates to biological environment engineering, and more specifically relates to the application of special microorganisms. It mainly uses special microbial bacteria to decompose and absorb malodorous gas, and converts it into carbon dioxide, water and microbial cell protein structure, so as to achieve the purpose of removing odor. Background technique [0002] Malodorous gas refers to the odor contained in the gas that makes people feel very disgusting and very unpleasant. The malodorous gas referred to in the present invention mainly refers to the gas containing malodorous substances such as hydrogen sulfide, sulfur dioxide, nitrogen dioxide, ammonia, trimethylamine, benzene, toluene and xylene exceeding a certain concentration. [0003] Malodorous gas has a serious impact on the ecological environment. The malodorous gas stimulates the olfactory cells through the stinky groups such as sulfur group and carboxyl group, which makes peopl...
