Abstract
Description
Technical Field
[0001] This utility model relates to the field of wastewater treatment equipment, specifically an oxidation selective device for wastewater treatment. Background Technology
[0002] Traditional wastewater treatment systems commonly incorporate biological selector tanks and contact oxidation tanks. Biological selector tanks remove microscopic particles from wastewater through microbial action. Typically, a biological selection tank is used, with a retention time of 6-12 hours. This time depends on factors such as water quality and wastewater discharge standards to ensure sufficient degradation of organic matter by microorganisms. Contact oxidation tanks, often included, remove microscopic particles and residual organic matter through aerobic aeration, with a retention time of 4-8 hours to ensure further degradation of organic matter. However, because the volume of wastewater generated is typically large, and the aforementioned wastewater treatment systems require sufficient time for treatment—both for microbial decomposition of organic matter and for sediment formation—the treatment process takes time and cannot be rapid. Furthermore, if a single wastewater treatment system reaches its maximum treatment capacity, wastewater may accumulate and accumulate, failing to meet the requirements for rapid treatment.
[0003] To address the aforementioned issues, an oxidation selection device for wastewater treatment is designed to ensure the rapid reproduction of microorganisms in the biological selection tank and contact oxidation tank, thereby accelerating the decomposition efficiency of organic matter in wastewater and shortening the wastewater treatment time. Utility Model Content
[0004] The purpose of this invention is to provide a wastewater treatment oxidation selection device that ensures the rapid reproduction of microorganisms in the biological selection tank and contact oxidation tank, thereby accelerating the decomposition efficiency of organic matter in wastewater and shortening the wastewater treatment time.
[0005] To achieve the above objectives, this utility model employs the following technical solution:
[0006] An oxidation selection device for wastewater treatment includes sunspot photochemical components installed in the biological selection tank and the contact oxidation tank.
[0007] An aeration head is installed at the lower end of the biological selection tank and the contact oxidation tank, and aeration is delivered into the biological selection tank and the contact oxidation tank through the aeration head.
[0008] The sunspot photochemical component includes a top arc panel and a photochemical tube. The photochemical tube is adhered to the lower part of the inner arc surface of the top arc panel, and the top arc panel and the photochemical tube are aligned in the same direction. Multiple small holes are evenly spaced and staggered on the photochemical tube, and each small hole is connected to the interior of the photochemical tube.
[0009] Biological rope packing material is filled in the upper part of the biological selection tank and the contact oxidation tank.
[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0011] Unlike traditional wastewater treatment systems, the installation of black spot photochemical components and aeration heads allows air bubbles to remain in the biological selection tank and contact oxidation tank for a longer period of time. This enables microorganisms to better perform respiration, resulting in faster and greater microbial reproduction. Consequently, organic matter in the wastewater is decomposed more quickly, shortening the treatment time in the biological selection tank and contact oxidation tank, thereby shortening the overall wastewater treatment cycle.

[0017] The present invention will be further illustrated below with reference to specific embodiments. It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of the present invention. Furthermore, it should be understood that after reading the teachings of this invention, those skilled in the art can make various alterations or modifications to the present invention, and these equivalent forms also fall within the scope defined in this application.
[0018] The biological treatment tank is used, with a retention time of approximately 6-12 hours. This time setting depends on factors such as water quality and wastewater discharge standards to ensure sufficient degradation of organic matter by microorganisms. An additional contact oxidation tank (2) is added, using aerobic aeration to remove fine particulate matter and residual organic matter, with a retention time of approximately 4-8 hours to ensure further degradation of organic matter. However, because the amount of wastewater generated is relatively large, and the aforementioned wastewater treatment system needs sufficient time for treatment—both for microbial decomposition of organic matter and for sediment formation—the treatment process requires a certain amount of time and cannot be completed quickly. Furthermore, if a single wastewater treatment system reaches its maximum treatment capacity, the wastewater may not be treated in a timely manner, leading to accumulation and failing to meet the requirements for rapid treatment.
[0019] Therefore, based on the above problems, an oxidation selection device for wastewater treatment is designed:
[0020] Biological rope packing material 8 is filled in the upper part of the biological selection tank 1 and the contact oxidation tank 2, and a sunspot photochemical component 3 is arranged below the biological rope packing material 8. The upper ends of the biological selection tank 1 and the contact oxidation tank 2 are connected, and an aeration head 4 is arranged at the lower end of the biological selection tank 1 and the contact oxidation tank 2 to deliver aeration into the biological selection tank 1 and the contact oxidation tank 2. The specific application of the sunspot photochemical component 3 and the aeration head 4 is as follows:
[0021] In the biological selection tank 1 and the contact oxidation tank 2, the aeration head 4 at the bottom delivers gas to both tanks. Firstly, this bubble mass transfer process effectively increases the solubility of oxygen in the water, providing the necessary conditions for the growth of aquatic microorganisms and the degradation of organic matter. It also increases the path and time for oxygen transport by bubbles in the water, allowing microorganisms more time to contact oxygen for decomposition, thereby increasing the number of microorganisms per unit area and resulting in higher and faster decomposition efficiency. Secondly, the rising of bubbles in the water creates water flow and turbulence. Under the action of the sunspot photochemical component 3, the bubbles are broken into smaller bubbles, increasing the effective mixing and contact time between organic matter and microorganisms in the water, thus promoting the degradation of organic matter and the growth of microorganisms. Finally, the continuous generation of oxygen bubbles by aeration, with the rising oxygen bubbles constantly impacting the openings on the sunspot photochemical device, ensures effective and thorough mixing and contact between the sunspot photochemical agent and the oxygen, organic matter, and microorganisms in the water. Furthermore, the black spot photochemical component 3 contains a black spot photochemical agent, which can modify and activate microorganisms through mutagenesis, thereby enhancing their activity and stability. The combination of these two components allows for the cultivation and domestication of highly active and adaptable microbial populations and various microorganisms within the black spot photochemical three-phase separator. As the water flow and bubbles rise, these microorganisms attach to the biological packing material and continue to grow. The black spot photochemical agent in the sludge can ultimately be reused through sludge recirculation.
[0022] Because it's necessary to ensure that more bubbles are generated and absorbed by more microorganisms during gas delivery from the aeration head 4, the black spot photochemical component 3 includes a top arc panel 5 and a photochemical tube 6. The photochemical tube 6 is attached to the lower part of the inner arc surface of the top arc panel 5, and the top arc panel 5 and the photochemical tube 6 are aligned in the same direction. Multiple small holes 7 are evenly spaced and staggered on the photochemical tube 6, and each small hole 7 is connected to the interior of the photochemical tube 6. The small holes 7 on the photochemical tube 6 allow rising gas to be disrupted by the irregular shape of the holes 7, breaking larger bubbles into smaller ones. These smaller bubbles are then utilized by more microorganisms as they rise. Furthermore, the top arc panel 5 restricts and blocks the rising bubbles, slowing their ascent and allowing a greater concentration of smaller bubbles at the smooth tube location. This enables microorganisms at that location to multiply and decompose the wastewater over a large area, further accelerating the decomposition of organic matter. Furthermore, as mentioned above, the upper part of the biological selection tank 1 and the contact oxidation tank 2 is filled with biological rope packing material 8. The biological rope packing material 8 provides a carrier for the reproduction and decomposition of microorganisms. The biological rope packing material 8 can slow down the rate of bubble rise and provide an attachment carrier for the bubbles when they rise, so that the microorganisms at the location of the biological rope packing material 8 can grow, develop and reproduce rapidly, thereby further accelerating the decomposition of organic matter in the wastewater.
[0023] Therefore, an oxidation selection device for wastewater treatment can ensure the rapid reproduction of microorganisms in the biological selection tank 1 and the contact oxidation tank 2, thereby accelerating the decomposition efficiency of organic matter in wastewater and shortening the wastewater treatment time.
