Description

Technical Field

[0001] This utility model relates to the field of pharmaceutical wastewater treatment technology, specifically a photocatalytic pharmaceutical wastewater treatment device. Background Technology

[0002] Pharmaceutical wastewater has a complex composition, typically containing high concentrations of organic pollutants, bioinhibitory substances, and recalcitrant chemicals. Traditional biochemical treatment methods are often ineffective in treating it, and the pressure to meet discharge standards is increasing.

[0003] Advanced oxidation technologies, as a highly efficient method for treating recalcitrant organic wastewater, have shown promising application prospects in the field of pharmaceutical wastewater treatment. Among them, photocatalysis technology utilizes ultraviolet light to excite catalysts to generate highly oxidizing free radicals, which can effectively decompose organic pollutants in wastewater and is currently one of the hot topics in research and application.

[0004] In practical applications, to ensure the effectiveness of ultraviolet light irradiation on wastewater, the quartz sleeve used to protect the ultraviolet lamp tube often needs to extend below the surface of the wastewater. However, suspended solids, colloids, and reaction precipitates in pharmaceutical wastewater easily adhere to the outer wall of the quartz sleeve, forming a layer of dirt. This layer of dirt will severely hinder the transmission of ultraviolet light, significantly reduce the efficiency of photocatalytic reaction, resulting in unsatisfactory wastewater treatment effect, or even causing system failure.

Outside the wastewater treatment tank 1, there are also a pharmaceutical wastewater input mechanism, a catalyst addition mechanism, a hydrogen peroxide addition mechanism, and a stirring mechanism that does not contact other equipment in the wastewater treatment tank 1. These external mechanisms are all existing technologies and will not be described in detail here.

[0018] The wastewater treatment tank 1 is equipped with multiple photocatalytic devices, each including a quartz sleeve 201. The bottom of the quartz sleeve 201 is fixed to the bottom of the wastewater treatment tank 1. An ultraviolet lamp is fixedly installed inside the quartz sleeve 201. The quartz sleeve 201 has extremely high transmittance to ultraviolet light, allowing the ultraviolet light to directly irradiate the catalyst (such as TiO2) and pollutant molecules in the water. An external power line passes through the bottom of the wastewater treatment tank 1 and the bottom of the quartz sleeve 201 to power the ultraviolet lamp inside the quartz sleeve 201.

[0019] The sewage treatment tank 1 is equipped with a flushing mechanism that can move up and down. The flushing mechanism includes multiple annular pipes 301. The number of annular pipes 301 and quartz sleeves 201 is the same, and they are respectively sleeved on the outside of the quartz sleeves 201. At least four high-pressure nozzles 302 are fixedly connected inside the annular pipes 301. The high-pressure nozzles 302 are inclined and face the surface of the quartz sleeves 201, and can spray water to flush the surface of the quartz sleeves 201. A connecting pipe 303 is fixedly connected between the annular pipes 301 to connect the two annular pipes 301. A diversion pipe 304 is fixedly connected between the connecting pipes 303 to divert external water flow into the connecting pipe 303. The sewage treatment tank 1 is equipped with a lifting mechanism and a connecting mechanism. The lifting mechanism can drive the flushing mechanism to move up and down through the connecting mechanism. The lifting mechanism includes an electric telescopic rod 401, which is connected to an external power source and controlled by an external switch. The electric telescopic rod 401 is fixed to one side of the sewage treatment tank 1. A lifting connecting rod 402 is fixedly connected to the top of the electric telescopic rod 401. A guide rod 403 is fixedly connected to the top of the sewage treatment tank 1. The guide rod 403 and the lifting connecting rod 402 are slidably connected. The connecting mechanism includes a fixed sleeve 501, which is fixed to the outer surface of the connecting pipe 303. An inclined fixed connecting rod 502 is fixedly connected between the fixed sleeves 501. One end of the fixed connecting rod 502 is fixedly connected to the lifting connecting rod 402 and can move up and down with the lifting connecting rod 402. A water supply mechanism is provided on the sewage treatment tank 1. The water supply mechanism includes a booster pump 601 fixed to one side of the sewage treatment tank 1. The booster pump 601 is existing technology, externally powered, and its inlet is connected to an external clean water input pipe to realize clean water input.

The bottom of the corrugated pipe 604 is fixedly connected to a diversion pipe 304. When the diversion pipe 304 moves downward, it will pull the corrugated pipe 604, causing the corrugated pipe 604 to extend and ensuring water supply to the diversion pipe 304.

[0020] The working principle of the photocatalytic pharmaceutical wastewater treatment device provided by this utility model is as follows: After prolonged use, stains will accumulate on the surface of the quartz sleeve 201. After discharging the pharmaceutical wastewater that has undergone catalytic treatment, the pressurized water pump 601 and the electric telescopic rod 401 can be started. The pressurized water pump 601 will input external clean water into the diversion pipe 304 through the water supply pipe 602 and the corrugated pipe 604. The diversion pipe 304 will divert the clean water into the connecting pipe 303, and then input it into the annular pipe 301 through the connecting pipe 303. Finally, it will be sprayed onto the surface of the quartz sleeve 201 through the high-pressure nozzle 302. The electric telescopic rod 401 drives the fixed connecting rod 502 to move up and down via the lifting connecting rod 402. The fixed connecting rod 502 drives the connecting pipe 303 to move up and down via the fixed sleeve 501. The connecting pipe 303 drives the annular pipe 301 and the high-pressure nozzle 302 to move up and down. During the up and down movement of the high-pressure nozzle 302, clean water is sprayed out to rinse the quartz sleeve 201, so as to clean the stains on the surface of the quartz sleeve 201 and ensure the transmittance of the quartz sleeve 201 to ultraviolet light.

[0021] Compared with related technologies, the photocatalytic pharmaceutical wastewater treatment device provided by this utility model has the following beneficial effects: This invention uses the up-and-down movement of the annular tube 301 and the high-pressure nozzle 302 to spray clean water to rinse the surface of the quartz sleeve 201, thereby cleaning away the stains on the surface of the quartz sleeve 201 and preventing the stains from adhering to the surface of the quartz sleeve 201 and affecting the light transmittance of the quartz sleeve 201 to ultraviolet light, which in turn affects the photocatalytic efficiency of pharmaceutical wastewater.
