Description

Technical Field

[0001] The utility model relates to the technical field of aerobic biological sewage treatment, in particular to a biological aerobic aeration reactor. Background Art

[0002] Aerobic biological treatment refers to a treatment method that uses aerobic microorganisms to carry out biological metabolism under aerobic conditions to degrade organic matter, making it stable and harmless. It is widely used in sewage and domestic waste disposal.

[0003] Currently, when sewage is purified using aerobic organisms, aerobic bacteria are generally added directly to the sewage pool and aeration facilities are installed to achieve biochemical treatment. In actual operation, aerobic bacteria and degradation products are continuously deposited at the bottom of the pool, requiring the entire pool to be cleaned, which is inconvenient to maintain. In addition, when draining, suspended matter and bacteria will flow out with the water, requiring the installation of filters for filtration, resulting in increased disposal costs. Utility Model Content

[0004] In view of the above-mentioned shortcomings of the prior art, the purpose of the present invention is to provide a biological aerobic aeration reactor that can be flexibly disassembled to facilitate the discharge of sludge and to promptly clean the sediment on the surface of the filter layer to ensure the filtering effect.

[0006] Shell II, which contains a biological aerobic aeration reaction chamber;

[0007] The shell I is threadedly sleeved on the top of the shell II;

[0008] A housing III threadedly sleeved on the bottom of the housing II;

[0009] A quartz sand filter layer is provided in the housing 1;

[0010] A water inlet pipe and an air inlet pipe are fixedly connected to the bottom of the housing III; and

[0011] A heating structure for insulating the shell II.

[0012] In one embodiment, sealing gaskets are filled between the shell I and the shell II, and between the shell II and the shell III.

[0013] In one embodiment, the quartz sand filter layer includes two meshes and quartz sand filled between the two meshes.

[0014] In one embodiment, an exhaust port is provided through the top of the shell 1, and a water outlet pipe is fixedly installed through the corresponding side wall of the shell 1.

[0015] Furthermore, valves are installed on both the water inlet pipe and the water outlet pipe, and the water inlet pipe is located at a position on the side corresponding to the air inlet pipe.

[0016] In one embodiment, the heating structure includes a heat-insulating interlayer fixedly mounted on the outside of the shell II, and a hot water inlet and a hot water outlet opened on the heat-insulating interlayer.

[0017] Furthermore, the hot water inlet and the hot water outlet are respectively located at corresponding two sides of the shell II, and the hot water inlet and the hot water outlet are communicated with the cavity in the thermal insulation interlayer.

[0018] Compared with the prior art, the beneficial effects of the present invention are: the aeration reactor is a combined structure and can be flexibly disassembled to facilitate the discharge of sludge. In addition, while utilizing air-water mixing to fully mix the sewage and aerobic bacteria to improve the purification quality, the air-water mixed flow also has a flushing effect on the quartz sand filter layer, thereby promptly cleaning the deposits on its surface and ensuring the filtration effect.

[0024] The present invention will be described in detail below with reference to the accompanying drawings.

[0025] See also Figure 1-3 This embodiment provides a biological aerobic aeration reactor, which includes a shell II2, a shell I1 threadedly mounted on the top of the shell II2, a shell III3 threadedly mounted on the bottom of the shell II2, a quartz sand filter layer 4 arranged in the shell I1, a water inlet pipe 8 and an air inlet pipe 9 fixedly connected to the bottom of the shell III3, and a heating structure for insulating the shell II2.

[0026] An exhaust port is provided through the top of the housing I1. This port maintains pressure balance within the reactor as aerobic bacteria degrade organic matter in the water through biological metabolism. Furthermore, bacteria can be introduced through the exhaust port and settle into the biological aerobic aeration reaction chamber. A water outlet pipe is fixedly installed through a corresponding side wall of the housing I1. The water inlet pipe 8 is located on the side corresponding to the air inlet pipe 9. Both the water inlet pipe 8 and the water outlet pipe are equipped with valves.

[0027] A biological aerobic aeration reaction chamber is defined within the housing II2. Sealing gaskets are placed between the housings I1 and II2, and between the housings II2 and III3. In this embodiment, the housings I1, II2, and III3 form the reactor's outer shell, which is flexibly disassembled. Disassembling the housing III3 facilitates sludge discharge, making cleaning simple and convenient.

[0028] The quartz sand filter layer 4 includes two meshes and quartz sand filled between the two meshes. Physical purification is performed based on the quartz sand filter layer 4, that is, the water after microbial purification is first filtered through the quartz sand filter layer 4 to intercept suspended impurities before being discharged.

[0029] The heating structure includes an insulating interlayer 5 fixedly mounted on the exterior of the housing II2, and a hot water inlet 6 and outlet 7 provided on the insulating interlayer 5. The hot water inlet 6 and outlet 7 are located on opposite sides of the housing II2 and communicate with the cavity within the insulating interlayer 5. In this embodiment, hot water is introduced into the insulating interlayer 5 via the hot water inlet 6. The hot water flows within the insulating interlayer 5 and is wrapped around the exterior of the housing II2, thereby assisting in heating the biological aerobic aeration reaction chamber through heat conduction, thereby maintaining the optimal reaction temperature and accelerating the degradation of organic matter.

[0030] The aeration reactor of this embodiment purifies wastewater as follows: Sewage is fed through an inlet pipe 8 into the purification chamber formed by the combined components of housings I1, II2, and III3. Under the biological metabolism of aerobic bacteria, organic matter in the wastewater is degraded into harmless inorganic substances, achieving purification. While the aerobic bacteria are carrying out their biological metabolism, air is introduced through an inlet pipe 9 for aeration, providing the oxygen required for the aerobic bacteria's metabolism. During this process, a heating structure assists in heating the biological aerobic aeration reaction chamber to maintain the optimal reaction temperature and accelerate the degradation of organic matter. After the reaction is complete, the drain pipe is opened, and the water, having undergone microbial purification, is filtered through a quartz sand filter layer 4 before being discharged along the drain pipe.

[0031] In summary, the aeration reactor of this embodiment has the following advantages compared to the traditional biological aerobic aeration purification mode: the aeration reactor of this embodiment is a combined structure and can be flexibly disassembled to facilitate the discharge of sludge. In addition, while utilizing air-water mixing to fully mix the sewage and aerobic bacteria to improve the purification quality, the air-water mixed flow also has a flushing effect on the quartz sand filter layer 4, thereby cleaning impurities on its surface in time to ensure the filtration effect.

[0032] The naming of the various components involved is based on the functions described in the specification, and is not limited to the specific nouns used in the present invention. Those skilled in the art may also choose other nouns to describe the names of the various components of the present invention.
