Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, specifically an advanced oxidation wastewater treatment device. Background Technology

[0002] With increasingly stringent national environmental standards and requirements for wastewater reuse, traditional wastewater treatment technologies are no longer sufficient to meet technological demands, thus creating a need for advanced wastewater treatment technologies. Advanced oxidation technology is an emerging water treatment technology characterized by the generation of strong oxidizing free radicals such as hydroxyl radicals during the reaction process. Under reaction conditions involving high temperature and pressure, electricity, sound, light irradiation, and catalysts, its oxidation capacity is greatly enhanced, effectively degrading pollutants in water and oxidizing large, recalcitrant organic molecules into low-toxicity or non-toxic small molecules, thus effectively improving the biodegradability of wastewater.

[0003] A search revealed that patent publication number CN 219792661 U discloses an advanced oxidation wastewater treatment device, "including an advanced oxidation wastewater treatment device body; an oxidation tank disposed on the advanced oxidation wastewater treatment device body; a U-shaped frame fixedly installed on one side of the oxidation tank; an ozone diffusion and stirring mechanism disposed on the oxidation tank; a drive mechanism disposed on the oxidation tank; an ozone replenishment mechanism disposed on one side of the oxidation tank; and an ozone circulation mechanism disposed on one side of the oxidation tank." This wastewater treatment device only treats wastewater using ozone, and its oxidation and decomposition rate and capacity are not high enough. It is not effective enough when treating complex industrial wastewater and requires further improvement. Utility Model Content

[0004] The purpose of this invention is to provide an advanced oxidation wastewater treatment device to solve the problems mentioned in the background art.

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

[0006] An advanced oxidation wastewater treatment device includes a wastewater treatment tank, a filtration tank, and a sedimentation tank. The filtration tank is located on one side of the upper part of the wastewater treatment tank and is connected to it. Slots are provided on both sides of the filtration tank, and filter screens are movably inserted into the slots. An ultrasonic generator is installed at the bottom of the wastewater treatment tank. A bracket is installed on the outer wall of the wastewater treatment tank, and an ozone generator is mounted on the bracket. An ozone tube is connected to the bottom of the ozone generator, and part of the ozone tube is horizontally inserted into the bottom of the wastewater treatment tank. An aeration head is installed on the ozone tube. A first suction pipe is connected to the bottom of the wastewater treatment tank, and the other end of the first suction pipe is connected to the inlet of a suction pump located on the ground. A second suction pipe is connected to the outlet of the suction pump, and the other end of the second suction pipe is located above the sedimentation tank. A lamp panel is installed on the sedimentation tank, and an ultraviolet germicidal lamp is installed on the bottom surface of the lamp panel.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. This utility model incorporates an ultrasonic generator and an ozone generator. The ultrasonic generator emits ultrasonic waves that create cavitation bubbles in the liquid, which decompose organic pollutants in the water. The ozone generator produces ozone, which, through its strong oxidizing properties, oxidizes and decomposes pollutants in the wastewater. Ultrasonic waves also enhance the decomposition rate and mass transfer rate of ozone, as well as generate more active free radicals, thereby strengthening the oxidizing ability of ozone. Thus, the synergistic effect of ultrasonic waves and ozone can improve the degradation rate of pollutants and enhance the wastewater treatment effect on complex industrial wastewater.

The ultraviolet germicidal lamp at the bottom of the lamp panel can sterilize the sewage in the sedimentation tank with ultraviolet light. This can further eliminate bacteria, viruses and other microorganisms in the sewage, thereby ensuring the safe discharge and reuse of sewage. Attached Figure Description

The filter tank 2 is provided on one side of the upper part of the wastewater treatment tank 1 and is connected to the filter tank 2. Slots 3 are provided on both sides of the filter tank 2, and filter screen plates 4 are movably inserted into the slots 3. An ultrasonic generator 6 is installed at the bottom of the wastewater treatment tank 1. A bracket 11 is installed on the outer wall of the wastewater treatment tank 1, and an ozone generator 8 is installed on the bracket 11. An ozone pipe 9 is connected to the bottom of the ozone generator 8, and an ozone regulating valve 7 is installed on the ozone pipe 9. The ozone regulating valve 7 is used to control the ozone delivery flow rate. Part of the ozone pipe 9 is inserted horizontally to the bottom of the wastewater treatment tank 1, and an aeration head 10 is installed on the ozone pipe 9.

[0020] The bottom of the filter tank 2 is provided with a discharge port, and a discharge valve 12 is installed at the bottom of the discharge port. The discharge valve 12 is used to discharge the impurities in the filter tank 2 to the outside.

[0021] Please see Figure 1-3The bottom of the sewage treatment tank 1 is connected to a first suction pipe 15. The other end of the first suction pipe 15 is connected to the inlet of the suction pump 5 set on the ground. The outlet of the suction pump 5 is connected to a second suction pipe 16. The other end of the second suction pipe 16 is located above the sedimentation tank 13. A lamp panel 19 is installed on the sedimentation tank 13.

[0024] The working principle of this utility model is as follows:

[0025] In operation, wastewater is first transported to filter tank 2 through a wastewater pipe. Large particles of impurities in the wastewater are intercepted by the filter screen 4 in filter tank 2 to prevent subsequent pipe blockage. Then, the wastewater flows into wastewater treatment tank 1. Ultrasonic waves are emitted into the wastewater by ultrasonic generator 6. The ultrasonic waves generate cavitation bubbles in the liquid, which decompose organic pollutants in the water. At the same time, ozone generator 8 generates ozone, which is transported to each aeration head 10 through ozone pipe 9. The ozone is dispersed to various parts of wastewater treatment tank 1 through each aeration head 10. The strong oxidizing properties of ozone are used to oxidize and decompose pollutants in the wastewater. The wastewater is rapidly treated by the synergistic effect of ozone and ultrasonic waves. Then, the decomposed wastewater is transported to sedimentation tank 13 through first suction pipe 15 and second suction pipe 16 by suction pump 5 for sedimentation. During the sedimentation process, ultraviolet germicidal lamps 20 installed on the sedimentation tank can further eliminate bacteria, viruses and other microorganisms in the wastewater. The sediment can be discharged through sludge discharge pipe 17 through sludge discharge valve 18. The treated wastewater is discharged from drain pipe 21 through drain valve 22.
