Biological combined synergistic deodorization process and device thereof

Abstract

The invention discloses a biological combined synergistic deodorization process and a device thereof. An odor source is humidified and sequentially subjected to microbial filler deodorization and soil deodorization by a two-stage deodorization process, and finally freely escape through the top of a soil deodorization system. The deodorization device comprises a deodorization box, an odor pipeline and a humidifying pipeline, one end of the odor pipeline is communicated with the odor source, the other end of the odor pipeline is connected to an air inlet of the deodorization box, a fan is arranged on the odor pipeline, the humidifying pipeline is parallelly connected onto a deodorization pipeline in front of the fan, connected with a humidifier and used for humidifying odor in the odor pipeline, an air distribution layer, a primary deodorization layer and a secondary deodorization layer are serially connected into the deodorization box, the air distribution layer is communicated with the air inlet, the primary deodorization layer is a microbial filler deodorization system, and the secondary deodorization layer is a soil deodorization system. The structure of a biological deodorization device is adjusted, biological deodorization process features are combined, the multi-stage deodorization system is used for synergistic deodorization, the treatment efficiency of the deodorization system is guaranteed, integration degree is high, and treatment effects are good.

Description

technical field

[0001] The invention belongs to the odor control technology, and in particular relates to a biological combination synergistic deodorization process and a device thereof. Background technique

[0002] At present, the commonly used malodorous gas treatment methods mainly include physical methods, chemical methods and biological methods. Physical and chemical methods to deal with large flow, medium and low concentration of malodorous gas have problems such as large investment, complicated operation and high operating cost, which limit the scope of application. Biological deodorization technology is to use the life activities of active microorganisms gathered on porous and moist media under suitable environmental conditions to metabolize and degrade odorous substances, turning them into simple inorganic substances or forming their own cells, so as to achieve deodorization. flavor purpose. The biological method is favored by people because of its own remarkable...

Examples

Embodiment

[0031] see figure 1 , the embodiment in the figure is the preferred mode of the present invention, and the deodorization device as a whole includes an exhaust gas pipeline 101 , a humidification pipeline 201 , an ultrasonic humidifier 202 , a fan 3 , and a deodorization box 5 . Odor source 1 enters the deodorization box 5 after being humidified by the ultrasonic water mist from the humidification pipeline 201, and then deodorizes through the microbial filler layer and the soil deodorization layer in turn, and finally escapes freely through the soil deodorization layer .

[0032] In the biological deodorization system, in order to saturate the polluted gas with humidification, the uninterrupted circulation spray design is usually adopted, and the dissolved oxygen in the spray liquid is increased at the same time, which provides maintenance for the rich aerobic bacteria in the spray liquid. Prerequisites for activity and survival. In this embodiment, the process water is atomiz...
