Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, specifically a circulating wastewater treatment device. Background Technology

[0002] Wastewater treatment is a process designed to make wastewater meet the water quality standards for discharge into specific water bodies or for reuse. This process mainly uses physical, chemical and biological means to effectively remove or transform harmful substances in wastewater, thereby purifying the water. This is not only a key measure to protect the natural environment, but also promotes the reuse of water resources, reflecting the dual value of resource conservation and environmental protection.

[0003] As disclosed in CN212559783U, a circulating sewage treatment device relates to the field of sewage treatment technology, and more particularly to a circulating sewage treatment device. It includes a support frame, a filter box fixed to the top of the support frame, and an inlet hopper located at the top center of the filter box. A first sieve plate is installed inside the filter box, and a positioning plate is fixed to the front of one side of the first sieve plate. In this device, a control terminal, a second drain outlet, a transfer sleeve, a diversion pipe, a return pipe, a mixing box, a third drain outlet, and a water pump are configured. By closing the second drain outlet and opening the third drain outlet with the control terminal, the pump, once started, draws the mixed liquid from the mixing box through the third drain outlet. The mixed liquid is then returned to the filter box after passing through the pump's output end, the transfer sleeve, the diversion pipe, and the return pipe, thus completing the entire circulating filtration process and ensuring the purification effect of the entire device.

[0004] Although the aforementioned patents can treat wastewater through filter boxes and mixing boxes, most of the aforementioned patents and most circulating wastewater treatment devices on the market cannot meet the requirements for effective purification under different water quality conditions. If effective purification is not carried out during the wastewater treatment process, the treated wastewater will still contain a certain amount of harmful substances, and may even generate new pollutants, thereby causing secondary pollution to water bodies and ecosystems.

[0005] Therefore, in order to solve the above problems, a circulating sewage treatment device urgently needs to be developed. Utility Model Content

[0006] The purpose of this invention is to provide a circulating sewage treatment device that has the advantages of high efficiency and stable treatment, and solves the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: A circulating sewage treatment device includes a sewage treatment tank. A partition and two baffles are fixedly connected to the inner cavity of the sewage treatment tank. The partition and the sewage treatment tank form a purification chamber. The left baffle and the partition form a stirring chamber. The two baffles form a sedimentation chamber. The right baffle and the sewage treatment tank form a treatment chamber.

The output shaft of the second motor is fixedly connected to a driving gear. A driven gear is fixedly connected to the surface of the air supply pipe. The driven gear meshes with the driving gear. A filter plate is installed through one side of the sewage treatment tank. One side of the filter plate extends into the inner cavity of the treatment chamber. The filter plate is located below the air supply pipe. A water guide pipe is connected to the lower front side of the sewage treatment tank. One end of the water guide pipe extends into the inner cavity of the treatment chamber. A water pump is fixedly connected to the left side of the top of the sewage treatment tank. The inlet end of the water pump is connected to the water guide pipe. The outlet end of the water pump is connected to an outlet pipe.

[0012] Beneficial effects: The technical solution of this application has the following technical effects: This utility model has the advantages of efficient and stable treatment. In actual use, sewage is first introduced into the mixing chamber and mixed with coagulant. This step causes the colloidal particles in the water that are originally difficult to settle to lose stability and aggregate into larger suspended solids. Subsequently, these suspended solids flow into the sedimentation chamber and slowly sink to the bottom of the pool under the action of gravity, forming a sludge layer. Meanwhile, the clean water gradually rises and enters the treatment chamber. In the treatment chamber, oxygen is injected into the water through the air supply pipe. During this process, the air supply pipe not only transports gas but also drives the stirring blades connected to it to rotate, effectively accelerating the mixing and reaction of oxygen and water, thereby further biologically treating the sewage. After that, the sewage flows through the filter plate below the air supply pipe and is further purified. Finally, the purified water flows into the clean water chamber through the water guide pipe, completing the entire efficient and stable sewage treatment process.

The filter plate 15 is located below the air supply pipe 9. A water guide pipe 16 is connected to the lower front side of the wastewater treatment tank 1. One end of the water guide pipe 16 extends into the inner cavity of the treatment chamber. A water pump 17 is fixedly connected to the left side of the top of the wastewater treatment tank 1. The water inlet of the water pump 17 is connected to the water guide pipe 16. The water outlet of the water pump 17 is connected to the water outlet pipe 18. One end of the water outlet pipe 18 extends into the clean water chamber.

[0022] Specifically, the top of the sewage treatment tank 1 is connected to a clean water outlet pipe 19, a sewage inlet pipe 20, and an inlet pipe 21. The bottom end of the clean water outlet pipe 19 extends into the inner cavity of the clean water chamber, and the bottom ends of the sewage inlet pipe 20 and the inlet pipe 21 extend into the inner cavity of the mixing chamber.

The gas delivery pipe 9 then delivers gas through the gas outlet 10. Gas is delivered into the treatment chamber to increase the dissolved oxygen content in the water, promote the growth and metabolic activities of microorganisms, and accelerate the decomposition of organic matter in the sewage. The output shaft of motor 12 drives the drive gear 13 to rotate, and the drive gear 13 drives the gas delivery pipe 9 to rotate through the driven gear 14. The gas delivery pipe 9 drives the stirring blade 11 to stir the water in the treatment chamber. The water, after being evenly mixed with suspended solids, microorganisms and dissolved oxygen, is purified by the filter plate 15. The completely purified water flows to the bottom of the treatment chamber. The water pump 17 is turned on, and the water inlet of the water pump 17 is transported to the outlet of the water pump 17 through the water guide pipe 16. The outlet of the water pump 17 is then guided into the clean water chamber through the outlet pipe 18, thus completing the purpose of circulating sewage treatment.
