Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment systems, specifically a wastewater treatment system with three-phase separation of sunspot photochemical reaction. Background Technology

[0002] Traditional wastewater treatment methods typically require wastewater treatment equipment to process the wastewater, followed by testing to ensure it meets standards before treatment needs are met. Existing wastewater treatment equipment often includes sedimentation tanks where sediment settles and undergoes aerobic and anaerobic decomposition by microorganisms. This process breaks down organic matter and causes further sedimentation, followed by adsorption of particulate matter, thus completing the wastewater treatment process. While such systems can treat wastewater effectively within a certain timeframe to meet discharge requirements, their biggest problem is treatment efficiency. Because the volume of wastewater generated is substantial, and these systems require sufficient time for microbial decomposition of organic matter and sediment formation, the treatment process takes time and cannot be rapid. Furthermore, if a single wastewater treatment system reaches its maximum capacity, wastewater may accumulate and accumulate, failing to meet the requirements for rapid treatment.

[0003] Based on the above problems, a wastewater treatment system with three-phase separation of sunspot photochemical reaction is designed to perform wastewater treatment operations more quickly. This allows wastewater to undergo multiple steps such as microbial decomposition and sedimentation in a shorter time, thereby greatly shortening the wastewater treatment time and enabling a higher wastewater treatment dosage per unit time, which is better suited to the needs of treating larger tonnage wastewater. Utility Model Content

[0004] The purpose of this invention is to provide a wastewater treatment system with three-phase separation of photochemical phases, which can perform wastewater treatment operations more quickly, enabling wastewater to undergo multiple steps such as microbial decomposition and sedimentation in a shorter time, thereby greatly shortening the wastewater treatment time, allowing for a higher wastewater treatment dosage per unit time, and better adapting to the needs of treating larger tonnage wastewater.

[0005] To achieve the above objectives, this utility model employs the following technical solution:

[0006] A wastewater treatment system with three-phase separation of sunspot photochemical reaction includes a biological selection tank, a contact oxidation tank, a secondary sedimentation tank, and a sand filter, wherein the biological selection tank, the contact oxidation tank, the secondary sedimentation tank, and the sand filter are connected in sequence.

[0007] The upper part of the biological selection tank and the contact oxidation tank is filled with biological rope packing material, and a sunspot photochemical component is set below the biological rope packing material; the upper ends of the biological selection tank and the contact oxidation tank are connected, and an aeration head is set 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] The secondary sedimentation tank is equipped with a bottom-sinking connecting pipe, the lower end of which is connected to the lower end of the biological selection tank; and the bottom-sinking connecting pipe is connected to a suction device, which is used to return and transport the sludge in the secondary sedimentation tank to the bottom of the biological selection tank.

[0010] The sand filter includes a filtration tank and a clear water tank. The filtration tank is connected to the secondary sedimentation tank, and the filtered wastewater enters the clear water tank after passing through the filtration tank. A backwash drain pipe is connected to the filtration tank, through which water is transported to the filtration tank and then discharged.

[0011] The filtration tank includes a fine tank, a medium tank, and a coarse tank. The fine tank, medium tank, and coarse tank are interconnected and the filtered particles are not the same. The fine tank, medium tank, and coarse tank are used to adsorb and filter sewage particles of different sizes.

[0012] The inlet of the biological selection tank is connected to an inlet that is connected to a self-gluing tank. The wastewater is initially filtered by the self-gluing tank and then discharged into the biological selection tank.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] This device utilizes biological selection tanks and contact oxidation tanks to achieve crucial steps in wastewater treatment. Biological treatment is the core of wastewater treatment, using microorganisms to remove microscopic particulate matter invisible to the naked eye. This is typically done in a biological treatment tank with a retention time of approximately 6-12 hours. This time depends on factors such as water quality and wastewater discharge standards to ensure sufficient degradation of organic matter by the microorganisms. Simultaneously, aerobic aeration removes microscopic particulate matter and residual organic matter. The retention time is generally approximately 4-8 hours to ensure further degradation of organic matter. Attached Figure Description

Detailed Implementation

[0021] 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.

[0022] Traditional wastewater treatment systems can process wastewater effectively within a certain timeframe to meet discharge requirements. However, the biggest problem with these systems is their treatment efficiency. Because the volume of wastewater generated is typically large, and these systems require sufficient time for treatment—including microbial decomposition of organic matter and sediment formation—the treatment process cannot be rapid. Furthermore, if a single wastewater treatment system reaches its maximum capacity, wastewater may accumulate and accumulate, failing to meet the requirements for rapid treatment.

[0023] Based on the above problems, a three-phase separation wastewater treatment system based on photochemical reaction is proposed, comprising a biological selector tank 1, a contact oxidation tank 2, a secondary sedimentation tank 3, and a sand filter 4, which are sequentially connected. The biological selector tank 1 removes microscopic particulate matter invisible to the naked eye from the wastewater through the action of microorganisms. This is typically done in a biological selection tank, with a retention time of approximately 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. The additional contact oxidation tank 2 removes microscopic particulate matter and residual organic matter through aerobic aeration. Its retention time is generally approximately 4-8 hours to ensure further degradation of organic matter. The secondary sedimentation tank 3 removes recalcitrant organic matter and nutrients, with a retention time of approximately 3-6 hours to further improve effluent quality. The sand filter 4 primarily removes residual nutrients and microorganisms, with a retention time of approximately 1-2 hours, ensuring that the effluent meets higher standards. The main problem with the above-mentioned wastewater treatment tanks is the long reaction time. Therefore, in order to shorten the wastewater treatment time, the following structural design is adopted:

[0024] Biological rope packing material 5 is filled in the upper part of the biological selection tank 1 and the contact oxidation tank 2, and a sunspot photochemical component 6 is arranged below the biological rope packing material 5. The upper ends of the biological selection tank 1 and the contact oxidation tank 2 are connected, and an aeration head 7 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 6 and the aeration head 7 is as follows:

[0025] In the biological selection tank 1 and the contact oxidation tank 2, the aeration heads 7 below deliver gas into these tanks. Firstly, this bubble mass transfer process effectively increases the solubility of oxygen in the water, providing the necessary conditions for the growth of microorganisms and the degradation of organic matter. It also increases the path and time for oxygen transport by bubbles, allowing microorganisms more time to contact oxygen for decomposition, thus increasing the number of microorganisms per unit area and resulting in higher and faster decomposition efficiency. Secondly, the rising of bubbles creates water flow and turbulence. Under the action of the sunspot photochemical component 6, the bubbles are broken into smaller bubbles, increasing the effective mixing and contact time between organic matter and microorganisms in the water, thereby promoting the degradation of organic matter and the growth of microorganisms. Finally, the continuous generation of oxygen bubbles during 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 6 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.

[0026] Because it is necessary to ensure that more bubbles are generated and absorbed by more microorganisms during gas delivery from the aeration head 7, the black spot photochemical component 6 includes a top arc panel 8 and a photochemical tube 9. The photochemical tube 9 is adhered to the lower part of the inner arc surface of the top arc panel 8, and the top arc panel 8 and the photochemical tube 9 are aligned in the same direction. Multiple small holes 10 are evenly spaced and staggered on the photochemical tube 9, and each small hole 10 is connected to the interior of the photochemical tube 9. The small holes 10 on the photochemical tube 9 allow the rising gas to be broken down by the irregular shape of the holes 10 upon contact, causing larger bubbles to be broken down into smaller bubbles. This allows more microorganisms to utilize these smaller bubbles as they rise. Furthermore, the top arc panel 8 installed here can restrict and block the rising bubbles, thereby slowing down the bubble rise time. This allows a larger number of smaller bubbles to concentrate at the smooth tube position, enabling microorganisms at that location to multiply and decompose over a large area, thus further accelerating the decomposition of organic matter in the wastewater. As mentioned above, the upper part of the biological selection tank 1 and the contact oxidation tank 2 is filled with biological rope packing 5. The biological rope packing 5 provides a carrier for the reproduction and decomposition of microorganisms, slows down the rate of bubble rise, and provides an attachment carrier for the rising bubbles. This allows microorganisms at the location of the biological rope packing 5 to grow, develop, and reproduce rapidly, further accelerating the decomposition of organic matter in the wastewater.

[0027] Further design and optimization of other structures are as follows:

[0028] The secondary sedimentation tank 3 is equipped with a bottom-connecting pipe 11, the lower end of which is connected to the lower end of the biological selection tank 1. The bottom-connecting pipe 11 is connected to a suction device, which recirculates the sludge from the secondary sedimentation tank 3 back to the bottom of the biological selection tank 1. This allows for the reuse of the sunspot photochemical agent and enables microorganisms to repeatedly enter the biological selection tank 1 and the contact oxidation tank 2, further accelerating the decomposition of organic matter by the microorganisms.

[0029] The sand filter 4 includes a filter tank 12 and a clear water tank 13. The filter tank 12 is connected to the secondary sedimentation tank 3, and the filtered wastewater enters the clear water tank 13 after passing through the filter tank 12. A backwash drain pipe 14 is connected to the filter tank 12, through which water is transported to the filter tank 12 and then discharged, thereby facilitating the cleaning of particulate matter generated during wastewater treatment. The filter tank 12 includes a fine tank, a medium tank, and a coarse tank, which are interconnected and filter different sizes of wastewater particles. The fine, medium, and coarse tanks adsorb and filter wastewater particles of different sizes.

[0030] The biological selection tank is connected to an inlet 15, which is connected to a self-gutter tank. The wastewater is initially filtered by the self-gutter tank and then discharged into the biological selection tank 1.

[0031] Therefore, a wastewater treatment system with three-phase separation based on sunspot photochemical reaction can perform wastewater treatment operations more quickly, enabling wastewater to undergo multiple steps such as microbial decomposition and sedimentation in a shorter time, thereby greatly shortening the wastewater treatment time and allowing for a higher wastewater treatment dosage per unit time, better meeting the needs of larger tonnage wastewater treatment.
