Description

Technical Field

[0001] The invention relates to the technical field of industrial wastewater treatment, and in particular to a degradation and disinfection treatment device for pharmaceutical industrial wastewater treatment. Background Art

[0002] Pharmaceutical industrial wastewater has the characteristics of complex composition, high concentration, deep chromaticity, high toxicity, and difficulty in biodegradation, which is a major problem in my country's industrial wastewater treatment field. This type of wastewater mainly comes from the production of raw materials, intermediate synthesis, product refining and other links, involving various types of drugs such as antibiotics, vitamins, hormones, and antiviral drugs. It contains a wide variety of pollutants, including organic matter, inorganic salts, heavy metals, biological inhibitors, etc., and the water quality and water volume fluctuate greatly, which brings certain difficulties to treatment.

[0003] After searching, it was found that among the existing sewage treatment technologies, most have a single function and can only achieve the degradation or elimination of organic matter, and there are problems such as secondary pollution or low treatment efficiency. For example, the current mainstream pharmaceutical wastewater treatment processes mainly include physical methods, chemical methods, biodegradation and combined technologies. The physical method is mainly suitable for filtering and adsorbing large-sized pollutants such as suspended matter and pigments. Pollutants dissolved in water cannot be eliminated by filtration and adsorption, and the treatment effect is poor. Its essence is the transfer process of pollutants, which cannot be completely eradicated; the chemical method mainly uses different types of chemical reagents such as flocculants and oxidants to remove or degrade heavy metals and organic matter in wastewater and kill bacteria and viruses. The effect is relatively ideal, but However, the costs are high and there is a risk of introducing secondary pollutants, which is not in line with the new concept of low-cost green environmental protection. Biodegradation technology is widely used in the treatment of wastewater with low pollutant content and easy biodegradation, such as domestic sewage. At present, there are still prominent problems such as long treatment cycle and inability to treat non-biodegradable organic matter. Most of them require multiple complex treatment processes for wastewater containing multiple pollution factors such as organic matter and bacteria. There is still a lack of effective low-cost treatment technology for difficult-to-degrade biopharmaceutical wastewater such as antibiotics. In order to achieve efficient and harmless degradation and disinfection of wastewater, improve the utilization rate of water resources, and ensure environmental safety, the sewage treatment field urgently needs a safe and efficient degradation and disinfection treatment solution for special wastewater such as pharmaceutical wastewater.

[0021] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0022] like Figure 1-Figure 7 As shown, the present invention discloses a degradation and disinfection treatment equipment for pharmaceutical industrial wastewater treatment, a sewage box 1, a reaction chamber 2 is installed on the top of the sewage box 1, a top cover 3 is installed on the top of the reaction chamber 2, a row of ultraviolet irradiation lamps 4 are installed obliquely on the inner side of the top cover 3, a trapezoidal platform 5 is installed on the inner side of the reaction chamber 2 on the top of the sewage box 1, a titanium oxide plate 7 with the same trapezoidal design is installed on the top of the trapezoidal platform 5, a water pump 8 is installed on the top of the sewage box 1, a shunt pipe 9 is installed on the upper end of one side of the reaction chamber 2, the shunt pipe 9 is located at the upper end of the trapezoidal platform 5, the shunt pipe 9 is connected to the outlet pipe of the water pump 8, the water inlet pipe of the water pump 8 is passed through the top of the sewage box 1, and a circulation reflux port 10 is provided on the lower side of the trapezoidal platform 5 at the top of the sewage box 1. The circulation reflux port 10 is located on the inner side of the reaction chamber 2, the hot wall reactors 6 are evenly arranged on the top of the trapezoidal platform 5, and a hot wall reactor 6 is also installed on the top of the sewage box 1 located on one side of the trapezoidal platform 5, and all the hot wall reactors 6 form a trapezoidal structure, and the titanium oxide plate 7 is fixedly attached to the top of the hot wall reactor 6.

[0023] As mentioned above, the photocatalytic technology is designed in the present invention, which utilizes photons to excite semiconductor photocatalysts to generate electron-hole pairs, directly or indirectly decomposing various organic pollutants into carbon dioxide, water and simple inorganic acids, thereby achieving the decomposition of trace organic matter and the killing of bacteria and viruses. Specifically, when the sewage front-end treatment is performed, the sewage is introduced from one side of the sewage tank 1, and then the ultraviolet irradiation lamp 4 and the water pump 8 are started, and the sewage is introduced into the reaction chamber 2 through the shunt pipe 9, starting from the top of the trapezoidal platform 5 and the titanium oxide plate 7, and gradually flows downward, and then returns to the sewage tank 1 from the circulation reflux port 10 to form a closed circulation treatment. In this process, the sewage is irradiated by the ultraviolet irradiation lamp 4 while flowing. At the same time, the inclined flow makes the water level of the titanium oxide plate 7 very shallow, which can be well irradiated by the ultraviolet irradiation lamp 4, and excites titanium dioxide to generate conduction band electrons and forbidden band holes, which respectively undergo redox reactions with dissolved oxygen and water molecules in the water to generate superoxide anions and hydroxyl free radicals. The hydroxyl free radicals attack the organic molecules in the water, oxidize and decompose them, and finally convert them into di Carbon dioxide, water and inorganic salts, and finally, with the continuous degradation of organic matter, the hot wall reactor 6 can provide a stable heating environment, which is helpful to control the temperature during the reaction process. The appropriate temperature can improve the photocatalytic activity of the titanium oxide plate 7, thereby accelerating the degradation of organic matter. After a period of time, the COD in the water gradually decreases, and the water quality is purified. At the same time, through the fluid dynamics design, it is ensured that the titanium oxide plate 7 can fully contact the organic matter in the sewage to improve the purification efficiency. There is no need to place the titanium oxide plate 7 underwater to avoid the presence of suspended matter, colloids, organic matter and other impurities in the static sewage. These impurities will absorb, scatter or reflect ultraviolet rays, thereby avoiding reducing the intensity and effectiveness of ultraviolet rays reaching the surface of the titanium oxide plate 7, and the treatment is more comprehensive, delicate and sufficient. It should be noted that a stirring structure can be installed inside the sewage tank 1 so that the COD is always evenly distributed in the water, or an aeration structure can be installed. This is an existing design, so the figure and text are not repeated. Finally, the sewage is discharged when the COD content index in the sewage is qualified through the COD detector of the existing design.

[0024] An inclined pre-filter plate 20 is installed on the inner wall of the sewage tank 1. The water inlet pipe of the sewage tank 1 and the circulation return port 10 are both located at the inclined upper end of the pre-filter plate 20, and a sewage discharge plate is hinged in the opening of the sewage tank 1 at the inclined lower end of the pre-filter plate 20. The water level inside the sewage tank 1 is located below the pre-filter plate 20, and the water inlet pipe of the water pump 8 passes through the pre-filter plate 20.

[0025] As mentioned above, through the design of the pre-filter plate 20, large particle impurities can be further filtered when the sewage is introduced to prevent these impurities from falling onto the titanium oxide plate 7 and affecting the photocatalytic effect. At the same time, due to the inclined surface design, the circulating water flow during the working process will also fall to the upper end of the inclined surface of the pre-filter plate 20, and the impurities will fall to the lower end of the inclined surface through impact, thereby facilitating subsequent cleaning work.

[0026] The inner wall of the top cover 3 is provided with a layer of water film 18 , and the area of ​​the water film 18 is the same as the inner area of ​​the top cover 3 .

[0029] As mentioned above, through the design of the cleaning part 14, the titanium oxide plate 7 can be reused. When cleaning is needed at the end of work, the sewage box 1 can be filled with clean water, and the water pump 8 is started to flush the titanium oxide plate 7. At the same time, the motor 1401 is started to drive the screw 1402 to rotate back and forth, and the trapezoidal brush plate 1403 moves left and right through the limited sliding of the cross bar 1404, and the titanium oxide plate 7 can be cleaned with the water flow, which effectively improves the cleaning efficiency.

[0030] An air guide port 19 is respectively provided at both ends of the top of the top cover 3. A threaded cover can be added to the air guide port 19, and both air guide ports 19 can be used to connect to the hot air delivery system.

[0033] As mentioned above, the trapezoidal baffle 15 is used for protection, and finally after the drying is completed, the staff can remove the trapezoidal baffle 15 and reach into the interior of the reaction chamber 2 with a handheld brush to remove a small amount of residual dirt, which is very convenient.

[0034] like Figure 1-Figure 3 As shown, a workbench 11 is installed on both sides of the sewage box 1, a ladder 12 is provided on one side of the workbench 11, a fence 13 is installed on the workbench 11, and a row of climbing frames 17 are vertically fixed on both sides of the sewage box 1, and the climbing frames 17 are located below the motor 1401 and the upper end of the trapezoidal baffle 15.
