Description

TECHNICAL FIELD

[0001] The utility model belongs to biological deodorization technical field, especially point to a three -segment biological deodorization equipment. BACKGROUND

[0002] Biological deodorization refers to the process of removing or reducing odor substances in the air by the metabolic action of microorganisms. This technology is widely used in leachate treatment stations with high odor concentration and unstable inlet concentration, old urban sewage treatment stations, industrial sewage treatment stations, garbage disposal sites, animal husbandry and other occasions, or places with extremely strict discharge requirements around the environment, to improve environmental air quality and reduce adverse effects on the surrounding environment and human health.

[0003] The existing biological deodorization equipment is mainly a two -segment structure of washing section (water washing section) combined with biological filter section, and the specific implementation mode has the following two kinds:

[0004] (1) The washing section is a separate circulating spray, and the humidifying water applied to the biological filter section is not reused, causing waste of water resources, and the circulating water of the washing section is easy to saturate, and the water is replaced too frequently.

[0005] (2) The washing section is communicated with the bottom of the biological filter section, and the circulating water is reused; however, the washing section has a relatively loose requirement on the quality of circulating water, while the biological filter has a relatively strict requirement on humidifying water to meet the environmental requirements of microorganisms, so the system needs to meet the requirement of the biological filter on humidifying water first when replacing water, which also causes waste of water resources.
