Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, and in particular to a micro-nano ozone oxidation wastewater treatment device. Background Technology

[0002] In today's era of rapid industrialization, the scale of industrial production continues to expand, and the amount of wastewater discharged from various industrial activities is increasing daily. Wastewater from industries such as chemicals, pharmaceuticals, printing and dyeing, and papermaking has an extremely complex composition, often containing large amounts of organic pollutants, heavy metal ions, high concentrations of salt, and harmful substances such as microorganisms. If this wastewater is discharged directly into natural water bodies without proper treatment, it will cause catastrophic damage to the ecological environment, seriously threatening the balance of aquatic ecosystems and leading to problems such as eutrophication and a sharp decline in biodiversity. At the same time, it also poses potential risks to human health, entering the human body through drinking water and the food chain, causing various diseases. With the continuous improvement of global environmental awareness, the requirements for industrial wastewater treatment are becoming increasingly stringent. For example, in recent years, my country has continuously revised and improved relevant environmental protection regulations, strictly limiting the concentration and total amount of various pollutants discharged into wastewater, and urging enterprises to adopt efficient and reliable wastewater treatment technologies to achieve compliance with discharge standards. Against this backdrop, traditional wastewater treatment technologies have revealed many limitations when dealing with complex wastewater, prompting researchers and engineers to continuously explore and develop new and efficient wastewater treatment technologies and devices. Micro-nano ozone oxidation wastewater treatment devices have emerged as an important innovative direction for solving current wastewater treatment problems.

[0003] In traditional micro-nano ozone oxidation wastewater treatment devices, the ultraviolet light and ozone from the ultraviolet irradiation method only act on the surface of the wastewater, making it difficult to oxidize deep pollutants. Furthermore, the wastewater flow is unguided, resulting in uneven irradiation and a large amount of recalcitrant residues. Utility Model Content

[0004] The purpose of this invention is to solve the problem in the existing micro-nano ozone oxidation wastewater treatment devices where ultraviolet light and ozone only act on the surface of the wastewater, making it difficult to oxidize deep pollutants. Therefore, a micro-nano ozone oxidation wastewater treatment device is proposed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a micro-nano ozone oxidation wastewater treatment device, comprising a chassis, two trapezoidal plates fixedly connected to the inner walls of both sides of the chassis, ultraviolet lamps equally spaced installed on the inner wall of the top of the chassis and the bottom of the trapezoidal plates, square holes opened on both sides of the chassis above the trapezoidal plates, a ring plate fixedly connected to one side wall of the chassis at the square hole, a connecting plate fixedly connected inside the ring plate, a drive motor equally spaced and fixedly connected to one side wall of the connecting plate, fan blades fixedly connected to the output end of the drive motor, a liquid pump fixedly installed on the front of the chassis near one side, an outlet pipe and a suction pipe fixedly connected to the output end and suction end of the liquid pump respectively, and the other ends of the outlet pipe and suction pipe passing through the chassis and fixedly connected thereto.

[0016] 1. In this utility model, the liquid pump drives the wastewater circulation, and the wastewater flows back and forth in the machine box through the liquid extraction pipe and liquid outlet pipe.

Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0027] Example 1, as Figure 1-5 As shown, this utility model provides a micro-nano ozone oxidation wastewater treatment device, including a casing 1.

Ultraviolet lamps 4 are installed at equal intervals on the inner wall of the top of the casing 1 and the bottom of the trapezoidal plates 3. Square holes 11 are opened on both sides of the casing 1 above the trapezoidal plates 3. A ring plate 12 is fixedly connected to one side wall of the casing 1 at the square hole 11.

The other ends of the outlet pipe 19 and the suction pipe 17 pass through the casing 1 and are fixedly connected to it.

[0028] The overall effect of Embodiment 1 is as follows: two trapezoidal plates 3 are fixedly connected to the inner walls of both sides of the chassis 1; ultraviolet lamps 4 are installed at equal intervals on the inner wall of the top of the chassis 1 and the bottom of the trapezoidal plates 3, which can irradiate the wastewater flowing below. Square holes 11 are opened on both sides of the chassis 1 above the trapezoidal plates 3; a ring plate 12 is fixedly connected to one side wall of the chassis 1 at the square hole 11; a connecting plate 14 is fixedly connected inside the ring plate 12; and a drive motor 15 is embedded and fixedly connected at equal intervals on one side wall of the connecting plate 14. The output end of the drive motor 15 is fixedly connected to the fan blades 16, which can drive the drive motor 15 to rotate the fan blades 16, allowing airflow to enter the inside of the casing 1. A liquid pump 18 is fixedly installed on the front of the casing 1 and near one side. The output end and the liquid suction end of the liquid pump 18 are fixed and connected to the liquid outlet pipe 19 and the liquid suction pipe 17, respectively. The other ends of the liquid outlet pipe 19 and the liquid suction pipe 17 pass through the casing 1 and are fixedly connected to it, which can allow the liquid pump 18 to extract the liquid inside the casing 1 through the liquid suction pipe 17, and the extracted liquid can be discharged from the liquid outlet pipe 19 and fall onto the uppermost trapezoidal plate 3.

[0029] Example 2, as Figure 1-5As shown, support legs 2 are fixedly connected to the bottom of the chassis 1 near the four corners, and the support legs 2 are all trapezoidal in shape; a waste liquid inlet pipe 5 is fixed and connected to one side wall of the chassis 1 near the top, and a waste liquid outlet pipe 6 is fixed and connected to the bottom of the chassis 1 near one corner; a temperature sensor 7 is fixedly installed at the bottom of the trapezoidal long plate 3; a COD / TOC sensor 8 is fixedly installed on one side wall of the chassis 1 near the bottom; a control panel 9 is fixedly installed on the surface of the chassis 1 near one side; an exhaust pipe 10 is fixed and connected to the top of the chassis 1 near one end; a mesh plate 13 is installed on the surface of the ring plate 12; a reflector 20 is fixedly installed on the inner walls of both sides of the chassis 1; and the trapezoidal long plates 3 on both sides are arranged vertically.

[0030] The overall effect of embodiment 2 is as follows: Support legs 2, all trapezoidal in shape, are fixedly connected to the bottom of the chassis 1 near its four corners, providing support for the bottom of the chassis 1; a waste liquid inlet pipe 5 is fixedly connected to one side wall of the chassis 1 near its top, and a waste liquid outlet pipe 6 is fixedly connected to the bottom of the chassis 1 near one corner, facilitating waste liquid inlet and outlet; temperature sensors 7 are fixedly installed at the bottom of the trapezoidal long plate 3, allowing the sensors to detect the internal temperature of the chassis 1; and COD / TOC sensors 8 are fixedly installed on one side wall of the chassis 1 near its bottom. This device is designed to sense the COD / TOC levels in wastewater. A control panel 9 is fixedly installed on the surface of the housing 1, near one side, allowing the control panel 9 to control the device. An exhaust pipe 10 is fixedly installed on the top of the housing 1, near one end, for venting. Mesh plates 13 are installed on the surface of the ring plate 12 to prevent larger particles from entering the ring plate 12. Reflectors 20 are fixedly installed on the inner walls of both sides of the housing 1 to improve the utilization of ultraviolet light. The trapezoidal plates 3 on both sides are arranged vertically to allow wastewater to flow downwards along the trapezoidal plates 3.

[0031] Working principle: When the liquid pump 18 is powered on, it draws wastewater stored in the casing 1 through the liquid extraction pipe 17. The liquid pump 18 acts as a power source, using mechanical work to pump the wastewater from the bottom of the casing 1 to the liquid outlet pipe 19, thus constructing a "power chain" for wastewater circulation. The wastewater is then reinjected into the casing 1 through the liquid outlet pipe 19 and, guided by gravity and the inclined structure of the trapezoidal long plate 3, flows slowly downwards along the surface of the long plate. The inclination angle and smooth surface treatment of the trapezoidal long plate 3 enable the wastewater to form a uniform thin layer flow, increasing the contact area with ultraviolet rays and ozone, thus solving the problem of traditional devices "only treating the surface". Ultraviolet lamps 4 are installed on the inner wall of the top of the casing 1 and the bottom of the trapezoidal long plate 3, respectively, irradiating the flowing wastewater from both the top and bottom dimensions. The top ultraviolet lamp 4 covers the surface of the wastewater, while the bottom lamp group of the long plate penetrates the thin layer of wastewater, achieving "three-dimensional" irradiation. This breaks the limitation of traditional devices that "only act on the surface." The reflectors 20 on the inner walls of both sides of the casing 1 reflect the ultraviolet light back to the wastewater area, using the reflected light to irradiate the wastewater a second time, improving the utilization rate of ultraviolet energy. During ultraviolet irradiation, some oxygen in the air is converted into ozone under the excitation of ultraviolet light. At the same time, if the device is connected to an external ozone generation system, the ozone is incorporated into the wastewater in the form of micro-nano bubbles. Micro-nano bubbles have a large specific surface area and rise slowly in the wastewater, prolonging the contact time between ozone and wastewater and improving solubility. The temperature sensor 7 is installed at the bottom of the trapezoidal long plate 3 to monitor temperature changes during the wastewater treatment process. The COD / TOC sensor 8 is installed on the side wall of the casing 1 to detect the chemical oxygen demand and total organic carbon of the wastewater in real time, reflecting the degree of pollutant degradation. The sensors transmit data to the control panel 9, forming a closed-loop feedback of "pollutant concentration - treatment parameters." If the temperature is too high, the control panel 9 automatically reduces the power of the ultraviolet lamp 4 and decreases the circulation frequency of the liquid pump 18 to reduce heat accumulation. If the COD / TOC ratio does not meet the standards, the intensity of the ultraviolet lamp 4 is increased and the circulation time is extended to enhance the oxidation reaction. The exhaust gas produced by the reaction is discharged through the exhaust pipe 10. If the ozone concentration in the exhaust gas is high, an external ozone decomposition device can be connected to convert the ozone into oxygen to avoid environmental pollution.

[0032] The wiring diagrams for the ultraviolet lamp 4, temperature sensor 7, COD / TOC sensor 8, control panel 9, and drive motor 15 in this utility model are common knowledge in the field. Their working principles are known technologies, and the appropriate models are selected according to actual use. Therefore, the control methods and wiring arrangements for the ultraviolet lamp 4, temperature sensor 7, COD / TOC sensor 8, control panel 9, and drive motor 15 will not be explained in detail.

Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
