Technical Field

[0001] The utility model relates to the technical field of tailwater treatment, in particular to a combined integrated treatment device of a structural regulating tank and tailwater treatment. Background Art

[0002] With the rapid development of industry and urbanization, a large amount of tailwater discharge has become a serious environmental problem. These tailwaters contain a large amount of harmful substances, such as heavy metals, organic matter and nutrients. If they are discharged directly into the natural environment without treatment, they will cause serious pollution and damage to water bodies, soil and ecosystems. Therefore, the research and development and application of tailwater treatment technology is particularly important.

[0003] Tailwater treatment equipment is a kind of equipment used to treat pollutants in water bodies, usually used to treat industrial wastewater, domestic sewage, aquaculture tailwater, etc. These equipment can effectively remove harmful substances in the water, make the water quality meet environmental protection standards, and reduce pollution to the environment. There are many types of tailwater treatment equipment, the most common ones are physical treatment equipment, chemical treatment equipment, biological treatment equipment, etc. Physical treatment equipment mainly uses physical principles to remove suspended matter, sediment, etc. in water, such as grids, sedimentation tanks, etc.; chemical treatment equipment uses chemical reactions to remove soluble substances in water, such as neutralization, oxidation, reduction, etc.; biological treatment equipment uses the metabolism of microorganisms to remove organic matter, ammonia nitrogen and other pollutants in water, such as activated sludge method, biofilm method, etc.

[0004] However, traditional tailwater treatment methods often have low treatment efficiency, large floor space and high operating costs, and are not suitable for tailwater treatment. The current integrated tailwater treatment equipment directly conducts circulation treatment if the treatment results do not meet the standards, which can easily cause purification loss of purification components and increase the maintenance cost of the equipment. We provide a combined integrated treatment equipment of a structural regulating tank and tailwater treatment. Utility Model Content
