Abstract
Description
A high-efficiency wastewater treatment system Technical Field
[0001] This utility model relates to the field of wastewater treatment technology, and specifically to a high-efficiency wastewater treatment system. Background Technology
[0002] Wastewater treatment is the process of purifying wastewater to meet the water quality requirements for discharge into a water body or for reuse. Wastewater treatment is widely used in various fields such as construction, agriculture, transportation, energy, petrochemicals, environmental protection, urban landscaping, healthcare, and catering, and is increasingly becoming a part of everyday life for ordinary people.
[0003] Currently, wastewater treatment equipment suffers from problems such as large footprint, high dissolved oxygen levels in anaerobic tanks, poor phosphorus removal, and unstable COD and ammonia nitrogen treatment effects.
[0004] In view of the above, this utility model is hereby proposed. Summary of the Invention
[0005] To address the shortcomings of existing technologies, this utility model provides a high-efficiency sewage treatment system to improve sewage treatment efficiency, reduce land area, and enhance sewage treatment effect. The high-efficiency sewage treatment system includes an air pump, a first power water pump, a second power water pump, a high-efficiency jet mixer, an aerobic tank, and an anaerobic tank.
[0006] The air pump and the first power water pump are respectively connected to the inlet of the high-efficiency jet mixer;
[0007] The aerobic tank is equipped with a vortex granular sludge reactor at the top and a sludge hopper at the bottom. The inlet of the vortex granular sludge reactor is connected to the outlet of the high-efficiency jet mixer. The sludge hopper has an opening that is connected to the inlet of the second power water pump. The outlet of the second power water pump is connected to the inlet of the high-efficiency jet mixer.
[0008] The anaerobic tank is provided with an inlet at the top and a first outlet at the bottom, and a composite filter layer is provided between the inlet and the outlet.
[0009] Preferably, the composite filter layer is composed of sponge iron filter media and manganese sand filter media.
[0010] Preferably, there are multiple swirl granular sludge reactors, and each swirl granular sludge reactor is provided with a switch between it and the high-efficiency jet mixer.
[0011] Preferably, a second outlet is provided at the top of the aerobic tank, and the second outlet is connected to the inlet.
[0012] The beneficial effects of this utility model are reflected in:
[0013] This utility model's high-efficiency wastewater treatment system utilizes a vortex granular sludge reactor in an aerobic tank to form aerobic activated granular sludge, which has a better treatment effect than conventional flocculent sludge and occupies less space. Furthermore, the use of a high-efficiency jet mixer ensures thorough mixing, resulting in high oxygen utilization in the aerobic tank and better contact between wastewater, oxygen, and activated granular sludge, thus improving treatment efficiency and effectiveness. Additionally, the composite filter layer in the anaerobic tank contains sponge iron and manganese sand filter media. Since the dissolved oxygen requirement in the anoxic tank is no greater than 0.5 mg / L, the sponge iron acts as an oxygen remover, controlling the dissolved oxygen below 0.5 mg / L, ensuring nitrogen and phosphorus removal in the denitrification reaction. Moreover, the manganese sand filter media effectively adsorbs and filters total phosphorus in the wastewater while also filtering suspended solids. Attached Figure Description

In addition, the use of a high-efficiency jet mixer 5 ensures thorough mixing, resulting in high oxygen utilization in the aerobic tank and better contact between wastewater, oxygen, and activated granular sludge, thus improving treatment efficiency and effect. Furthermore, the composite filter layer 12 in the anaerobic tank contains sponge iron and manganese sand filter media. Since the dissolved oxygen requirement in the anoxic tank is no more than 0.5 mg / L, the sponge iron, as an oxygen remover, can control the dissolved oxygen below 0.5 mg / L, ensuring denitrification and phosphorus removal in the denitrification reaction. Moreover, the manganese sand filter media can effectively adsorb and filter total phosphorus in the wastewater, while also filtering suspended solids in the water.
