Abstract
Description
Technical Field
[0001] This utility model relates to the field of wastewater treatment technology, and in particular to a treatment tank for fermentation treatment of high ammonia nitrogen wastewater. Background Technology
[0002] Ammonia nitrogen wastewater mainly originates from fertilizer, coking, petrochemical, pharmaceutical, food, and landfill industries. Large amounts of ammonia nitrogen wastewater discharged into water bodies can easily cause eutrophication and black, foul-smelling water, while also increasing the difficulty and cost of water treatment and even posing toxic effects on humans and organisms. Therefore, ammonia nitrogen wastewater needs to be processed before discharge to remove toxic substances and meet wastewater treatment standards. Fermentation treatment of high-ammonia nitrogen wastewater is a key environmental protection step in the food processing, pharmaceutical, and chemical industries. The treatment process requires efficient removal of ammonia nitrogen while simultaneously controlling the emission of volatile harmful gases. Traditional treatment tanks often use static adsorption, which suffers from uneven activated carbon distribution, low adsorption efficiency, and easy wall adhesion. Especially when treating high-viscosity or suspended solids-containing wastewater, frequent cleaning and maintenance severely restrict continuous production capacity.
[0003] Existing treatment tanks for fermentation treatment of high ammonia nitrogen wastewater fill a fixed layer with activated carbon. Wastewater flows from top to bottom through the carbon bed and relies on natural diffusion for adsorption. However, long-term operation can easily lead to a decrease in flux due to carbon layer caking. Alternatively, paddle stirring can be used to promote contact between activated carbon and wastewater, but traditional stirrers cannot avoid the problem of carbon particles depositing on the tank wall. Therefore, a treatment tank for fermentation treatment of high ammonia nitrogen wastewater is proposed to solve the above problems. Utility Model Content
