Problems solved by technology

The organic filter material is used for deodorization, and the filter material must be replaced every 2 to 5 years. As the operating time increases, the filter material will harden and the resistance will continue to increase, and the system will have a gas short circuit, which will affect the treatment effect; the deodorization device consists of a gas distribution layer , pool, ph meter, pickling or alkali washing device, organic filter, biological nutrient solution, circulating water pump and other equipment, the structure is complex and the operating cost is high; except for the one-time investment in equipment and installation costs, it must be done every 2-5 years Replacing the filter material and cultivating the strains, repeated installation and replacement of the f...

Embodiment 1

[0027] Such as figure 1 As shown, a device utilizing biological soil to filter and deodorize mainly includes four parts: an air induction device 5, a humidifying device 6, an air distribution device 3 and a biological soil device. The biological soil device is mainly composed of a housing 1 and a housing The pebble layer 4 and the biological soil layer 2 in the body 1 are composed of; the pebble layer 4 is arranged at the bottom of the shell 1, and the biological soil layer 2 is formed on it; the microorganisms in the biological soil layer 2 are mainly pseudo The biological soil in the biological soil layer 2 is a sandy soil with a filter performance of 20% to 40% and a pore diameter of 0.01 to 0.10 mm; the biological soil Vegetation 7 is planted above the layer 2; a water spraying device 8 is also arranged above the biological soil device.

Embodiment 2

[0031] Such as figure 1 Shown, a kind of device utilizing biological soil to filter and deodorize, with embodiment 1.

[0032] The odor gas to be treated comes from a medium-sized sewage treatment plant B. The odor source from the biological treatment unit is collected by the odor collection system and then enters the odor treatment system through the air induction device 5. The gas device 3 enters the biological soil layer 2 and is purified by contacting the biological soil layer 2 inoculated with microorganisms, and the purified gas is discharged from the soil. Spray the microbial solution to the soil regularly.

[0033] Table 2 shows the sources of odor and the total amount of odor in this sewage treatment plant.

Abstract

The invention provides a method for filtration deodorization by utilizing biological soil. The method is characterized in that obnoxious gas is collected and humidified and then is evenly distributed onto the bottom of the biological soil by a gas distributing device, and purification on obnoxious gas is realized by absorption of the biological soil and micro organism in the biological soil; and the micro organism in the biological soil is mainly pseudomonas and thiophilic bacillus. The invention also provides a filtration deodorization device utilizing the biological soil. The invention adopts biological filtration method to remove odour, hydrogen sulphide and organic gas in odour are absorbed on the surface of particle of soil filtering layer and on the surface of micro organism cell in the filtering layer, odour is absorbed by micro organism, organic gas participates micro organism metabolism and is oxidated into carbon dioxide and water; odour and soil provide oxygen, moisture and mineral nutrient components for metabolism of micro organism, deodorization effect is good, and no secondary pollution is produced.

Description

technical field [0001] The invention belongs to the fields of environmental protection and waste gas treatment, and in particular relates to a method and device for filtering and deodorizing by using biological soil. Background technique [0002] With the enhancement of people's awareness of environmental protection, the requirements for environmental quality are getting higher and higher, and they are more sensitive to the pollution caused by stench. Odor refers to a kind of psychological discomfort or disgust produced by gaseous substances through human sense of smell. Odor pollution is a kind of sensory public hazard and has become one of the seven major environmental public hazards in the world. During the operation of urban sewage treatment plants, strong odor is generated, which seriously affects the surrounding environment and poses a hazard to the health of staff and surrounding residents. [0003] The existing deodorization technologies and treatment devices are us...
