Description

Technical Field

[0001] The utility model relates to the technical field of wastewater treatment, in particular to a biodegradable wastewater reactor. Background Art

[0002] Biodegradation technology is a process that uses the metabolic ability of microorganisms to convert organic pollutants in wastewater into harmless or less harmful substances. Bioflocculation is a water treatment technology that uses microorganisms or their metabolites to achieve flocculation and precipitation of suspended particles in water. Based on the flocculation effect of microorganisms, the flocculants produced by microorganisms (such as polysaccharides, proteins, etc.) are used to aggregate suspended particles, colloids and soluble organic matter in the water into flocs, thereby facilitating the subsequent solid-liquid separation process.

[0003] During the bioflocculation process, an aeration structure needs to be set up inside the biodegradation wastewater reactor to provide dissolved oxygen to the water body. At the same time, by generating bubbles and stirring the water, it helps to mix the water body evenly, thus ensuring that the microorganisms are fully in contact with the pollutants.

[0004] However, the aeration structure of the current biodegradation wastewater reactor protrudes from the inner wall of the reactor, resulting in that during the mixing and stirring process, the aeration structure will hinder the rotational flow of the water body, causing uneven mixing, thereby affecting the effective contact between the flocculant and the pollutants and the formation of flocs. Since the aeration device hinders the flow of fluid, more energy will be required to achieve the required mixing effect, thereby increasing energy consumption.

[0005] To this end, we propose a biodegradation wastewater reactor to solve the existing problems. Utility Model Content

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0016] During use, the biodegradable wastewater reactor of the utility model can introduce the wastewater to be treated into the tank of the biodegradable wastewater reactor through the inlet, and connect the external power supply to make the electric heating block work to generate heat to provide a certain temperature environment for the flocculation reaction inside the tank;

Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0028] Example 1

[0029] like Figure 1-Figure 5 As shown, the present invention proposes a biodegradable wastewater reactor, comprising a tank body 5, a cover 8 and a main shaft 16. A support assembly is provided at the bottom end of the outer wall of the tank body 5, an electric heating assembly is provided on the outer wall of the tank body 5, and the cover 8 is provided at the top opening of the tank body 5. A main shaft 16 is provided on the cover 8 through a rotation of the drive assembly, and a short arm 13 and a long arm 14 are equidistantly provided on the main shaft 16. Air ducts 17 are provided on the short arm 13, the long arm 14 and the main shaft 16, and an aeration and feeding assembly is provided on the top end of the main shaft 16 for rotation.

[0030] Based on Example 1:

[0031] During use, the biodegradable wastewater reactor of the utility model can be used to introduce the wastewater to be treated into the tank body 5 of the biodegradable wastewater reactor through the inlet 7, and an external power supply is connected to make the electric heating block 15 work to generate heat to provide a certain temperature environment for the flocculation reaction inside the tank body 5;

[0032] Then the motor 11 works by meshing the gears with the ring gear 6, thereby driving the main shaft 16 to rotate, and the wastewater inside the tank 5 is stirred by the long arm 14 and the short arm 13 on the main shaft 16;

[0033] At the same time, the feeding pipe 9 is connected to the storage device of the external microbial flocculant, and the air duct 10 is connected to the external air pump structure. During this process, the high-speed airflow generated by the air pump passes through the air duct 10 into the air duct 17, and then the wastewater is aerated through the air duct 17. The rotating long arm 14 and short arm 13 ensure that the wastewater is fully aerated.

[0034] Furthermore, when the high-speed airflow passes through the air duct 10, a negative pressure is generated in the feeding tube 9 under the action of the jet and gravity, thereby introducing the microbial flocculant in the storage device into the air duct 10, and then driven by the wind, it is evenly sprinkled into the wastewater inside the tank body 5 through the air duct 17.

[0035] Example 2

[0036] like Figure 1-Figure 5 As shown, the biodegradable wastewater reactor proposed by the present invention, compared with the first embodiment, further includes:

[0037] An inlet 7 is provided on the cover 8, through which the wastewater to be treated can be introduced into the tank body 5 of the biodegradable wastewater reactor. The electric heating component is composed of an annular shell 4 and an electric heating block 15. The annular shell 4 is arranged on the outer wall of the tank body 5, and the electric heating block 15 is arranged between the inner wall of the annular shell 4 and the outer wall of the tank body 5. An external power supply is connected to enable the electric heating block 15 to generate heat to provide a certain temperature environment for the flocculation reaction inside the tank body 5.

[0038] The position of the short arm 13 corresponds to the position of the cone at the lower end of the tank body 5. Through the design of the short arm 13, the short arm 13 can stir the wastewater inside the cone at the lower end of the tank body 5 to ensure that the wastewater inside the tank body 5 is fully stirred and mixed.

[0039] A discharge port is provided at the bottom of the cone at the lower end of the tank body 5 , and a valve is provided at the discharge port. After flocculation is completed, the wastewater and the mixture thereof can be discharged from the tank body 5 through the discharge port.

[0041] The aeration and feeding assembly consists of a feeding pipe 9 and an air duct 10. The lower end of the air duct 10 is rotatably inserted into the air duct 17 of the main shaft 16. The feeding pipe 9 is arranged on the air duct 10 at a forty-five-degree angle. The high-speed airflow generated by the air pump passes through the air duct 10 and enters the air duct 17. The wastewater is then aerated through the air duct 17. The rotating long arm 14 and short arm 13 ensure that the wastewater is fully aerated. When the high-speed airflow passes through the air duct 10, negative pressure is generated in the feeding pipe 9 under the action of the jet and gravity, thereby introducing the microbial flocculant in the storage device into the air duct 10.

[0042] Furthermore, a throttle valve may be provided on the air duct 10 , and the throttle valve may be closed before the air pump is shut down to prevent waste water from being sucked into the air duct 10 .

[0043] The support assembly consists of a base plate 1, a support seat 2 and a support leg 3. The top of the support leg 3 is arranged on the tank body 5, the base plate 1 is arranged on the bottom end of the support leg 3, and the support seat 2 is arranged on the lower surface of the base plate 1. Through the design of the support assembly, it can be ensured that the device is stably placed in the designated position.
