Abstract
Description
Technical Field
[0001] The invention relates to the technical field of industrial wastewater treatment, in particular to a high-concentration industrial wastewater treatment device and process based on ozone-photocatalysis. Background Art
[0002] High-concentration wastewater mainly comes from a variety of industrial processes, including papermaking, leather, food, pharmaceuticals, pesticide production, etc. These industries produce a large amount of organic matter, phenolic substances, alcoholic substances, sugars, oils and fats during the production process, which are the main sources.
[0003] High-concentration wastewater has unstable water quality and complex components, including organic matter, heavy metals, etc. The pH, salt content, and heavy metal content vary greatly, making it difficult to treat. It is highly toxic and contains harmful substances such as cyanide and phenol, which can cause teratogenic or lethal effects on microorganisms. High-concentration wastewater has a wide range of sources and obvious characteristics, making it more complicated to treat. In practical applications, it is necessary to select a suitable treatment plan based on factors such as the nature of the wastewater, treatment requirements, and economic conditions to achieve the desired purification effect.
[0004] In the treatment of high-concentration industrial wastewater, high-efficiency ozone catalyst technology is a daily method. Through enrichment-catalytic activation-oxidative degradation, the degradation reaction speed and efficiency of residual organic matter in wastewater are greatly improved. The strong oxidizing properties of ozone are combined with the enrichment and catalytic activity characteristics of catalysts to more effectively solve a series of problems such as low ozone treatment efficiency, low ozone utilization rate, and high operating costs. Among them, ozone oxidation technology can improve ozone utilization rate by adding ozone catalysts, and at the same time increase COD removal rate to 30-50%. The advantages of ozone catalysts for industrial wastewater treatment are: High efficiency: The ozone catalytic efficiency is more than 4 times higher than that without catalysts. Subversive: Long life, can maintain activity for a long time, and can be restored to activity by rinsing. High utilization rate: Ozone is fully utilized with little residue. Economical: Save land and no secondary pollution.
[0005] Through ozone catalytic oxidation technology, ammonia nitrogen in wastewater can be converted into harmless substances, reducing the negative impact of wastewater on the environment and ecosystem. The principle of ozone catalytic oxidation technology to treat industrial park wastewater is to use ozone to undergo an oxidation reaction in wastewater to degrade organic matter into harmless water and carbon dioxide. In actual operation, steps such as oxygen supply, ozone generation, oxidation reaction, and gas-liquid separation are required. First, sufficient oxygen is supplied to the reactor through an oxygen supply system. Then, an ozone generator is used to generate ozone gas. Next, ozone gas is injected into high-ammonia nitrogen wastewater and an oxidation reaction is carried out in the reactor. Finally, the gas and liquid in the wastewater are separated by a gas-liquid separation device to obtain treated clean water.
[0006] Photocatalyst, also known as photocatalyst, is a general term for semiconductor materials with photocatalytic function, represented by titanium dioxide (TiO2). Photocatalyst technology does not consume earth energy or use harmful chemicals, but only uses the light energy of sunlight to remove and purify environmental pollutants at low concentrations. It can also be used as an antibacterial agent and mildewproof agent. Therefore, it is an environmental purification technology with broad application prospects. In addition to the functions of antibacterial, deodorizing and anti-fouling, photocatalysts can also be applied to the field of water purification. The titanium dioxide photocatalyst technology is used to degrade organic pollutants in water, especially when the concentration of organic pollutants in water is very high or difficult to treat by other methods. The purification effect of photocatalyst is very obvious.
[0007] For example, application number 202221931393.4 discloses a high-concentration industrial wastewater treatment equipment, including a shell, a feed box, an installation box, a bracket, a connecting block, a filter box and a control panel, wherein the feed box is fixedly connected to the top left side of the shell, the installation box is fixedly connected to the top middle of the feed box, the bracket is fixedly connected to the top right side of the shell, the connecting block is located on the upper side of the bracket, the filter box is fixedly connected to the top right side of the bracket, and the control panel is fixedly connected to the upper side of the right side wall of the shell.

[0008] However, the current high-concentration wastewater treatment equipment has a low ozone utilization rate, the energy consumption cost of ozone production is high, the cost of recycling and treating underutilized ozone tail gas is high, the adhesives in the wastewater treatment equipment are not easy to remove, the catalyst is not easy to replace, and the overall automation level is not high.

[0023] S2, when the first air inlet pipe enters the ozone gas, the air pipe solenoid valves on the first air outlet pipe and the second air outlet pipe are closed, and the gas enters the breathable membrane through the second air inlet pipe and the third air inlet pipe. After the reaction, the gas containing the residual ozone enters the return air zone and reaches the first air outlet pipe through the air outlet. The concentration monitor monitors the ozone concentration in the return air zone. When the concentration is higher than the set value, the air pipe solenoid valve on the first air outlet pipe is opened, and the air pipe solenoid valve on the second air inlet pipe is closed.

[0026] Compared with the prior art, the present invention has the following beneficial effects:
[0027] 1. By setting up a permeable ozone mechanism, the contact area between wastewater and ozone is increased, especially bubble-free aeration can be achieved, which greatly improves the oxygen transfer efficiency in wastewater. Under the same conditions, it greatly reduces the use time of ozone, reduces oxygen production efficiency, and reduces manufacturing costs.
[0028] 2. By setting up a concentration monitor, the first air outlet pipe, and an air pipe solenoid valve, when the ozone concentration is higher than the set value, it will be circulated into the wastewater for secondary utilization. When the concentration is lower than the set value, it will be discharged through the air pipe solenoid valve, thereby improving the utilization rate of the intake ozone and reducing the cost of recovering the discharged ozone.
[0029] 3. By setting the impact boss and the impact mandrel in the catalytic reaction mechanism, the problem of wastewater sediment sticking to the porous horn support platform during the catalytic oxidation process can be effectively solved. When the impact mandrel is acted upon by the cylinder and hits the porous horn support platform, vibration is generated, and the sediment sticking on the porous horn support platform is vibrated to the sewage collection area;
[0030] 4. By setting a porous speaker support platform and a porous cylinder, the contact area between the photocatalyst ball and the wastewater is increased. At the same time, the photocatalyst ball is affected by the liquid inlet pressure and flows into the liquid inlet. Under the pressure of the liquid inlet, the photocatalyst ball cannot enter the liquid inlet under normal working conditions and remains in the porous speaker support platform and the porous cylinder. When the photocatalyst ball needs to be replaced, it is discharged through the drain pipe with the reflux of the liquid inlet, which is convenient for the injection and replacement of the photocatalyst ball.
[0031] 5. By setting up a multi-level illumination mechanism, the contact surface between the ultraviolet light and the waste liquid and the photocatalyst balls in the waste liquid is increased, and the catalytic reaction is carried out at multiple levels and angles, which increases the reaction speed, reduces the energy consumption of equipment operation, and increases the waste liquid treatment capacity per unit time;
[0032] 6. By setting up a monitoring and control mechanism, the liquid after the catalytic reaction is monitored in real time. If it is qualified, it will be discharged. If it is unqualified, the catalytic reaction will continue to circulate, which improves the automation of the equipment; BRIEF DESCRIPTION OF THE DRAWINGS
