Description

Technical Field

[0001] The utility model mainly relates to the technical field of denitrification devices, in particular to a portable denitrification device. Background Art

[0002] Industrial wastewater and domestic sewage contain a large amount of nitrogen-containing compounds. If these nitrogen-containing compounds are discharged into the ocean and lakes without purification, they can easily cause eutrophication of water bodies in a short period of time. Therefore, purifying nitrogen-containing compounds in sewage is of great significance to protecting the water environment. Nitrogen-containing compounds in sewage include two major categories: organic nitrogen and inorganic nitrogen. Organic nitrogen includes protein, amino acid, amide and urea, etc., and inorganic nitrogen includes ammonia nitrogen, nitrate, nitrite, etc. Biological denitrification is a common method for denitrification of sewage, including two stages: nitrification and denitrification. The nitrification reaction stage is the process in which microorganisms convert ammonia nitrogen into nitric nitrogen under aerobic conditions, and the denitrification stage is the process in which microorganisms gradually convert nitrate nitrogen into nitrogen gas under anoxic conditions using organic carbon sources as electron donors.

[0003] For example, Chinese patent publication number CN217838639U discloses a sewage denitrification and denitrification device. The sewage denitrification and denitrification device comprises a denitrification filter tank, which is divided into a clear water area, a denitrification area, a deoxygenation area and a water distribution area from top to bottom, the water distribution area is provided with a water inlet, the deoxygenation area is provided with a deoxygenation filler layer, the deoxygenation area is used to reduce the dissolved oxygen concentration in the sewage, the denitrification area is provided with a denitrification filler layer, the denitrification area is used to reduce inorganic nitrogen in the sewage, the clear water area is provided with a water outlet, the sewage flows in from the water inlet, and passes through the water distribution area, the deoxygenation area, the denitrification area and the clear water area in sequence, and flows out of the denitrification and denitrification tank from the water outlet.

[0004] In the prior art, most of the denitrification processes used in sewage treatment plants are heterotrophic denitrification. Existing denitrification devices are large in unit volume and require a large installation space, which limits their application in space-constrained environments. Due to their large size and weight, large denitrification devices are not easy to move and deploy on site. Existing denitrification devices are large-scale devices, usually requiring higher initial investment and operating costs, and are more suitable for treating sewage of a specific scale or type, and may not be suitable for small-scale or special-demand applications.
