Description

Technical Field

[0001] This application relates to the field of water treatment technology, and in particular to a wastewater organic pollutant purification device and water treatment equipment. Background Technology

[0002] Currently, traditional methods for removing organic pollutants from wastewater include physical adsorption, flocculation and sedimentation, and chemical oxidation. However, their widespread application is limited by high treatment costs and the potential for secondary pollution. Advanced oxidation processes, such as ozone oxidation, have attracted much attention as an effective method for removing organic pollutants. They generate a powerful oxidant, such as hydroxyl radicals, which completely decompose recalcitrant organic pollutants into carbon dioxide, water, and inorganic ions without producing secondary pollution.

[0003] This advanced oxidation process is usually carried out in a reaction tank, where ozone is supplied to the wastewater by aeration equipment. The ozone comes into contact with the wastewater to degrade organic pollutants. At the same time, the reaction tank is equipped with packing material, which filters the wastewater as it flows through. However, existing reaction tanks of this type often experience packing blockage, requiring repeated shutdowns for cleaning, which affects the process progress. Utility Model Content

[0004] The purpose of this application is to provide a wastewater organic pollutant purification device and water treatment equipment, so as to solve to a certain extent the technical problem in the prior art where the conventional reaction tank is designed as a single tank with a single chamber structure and the packing is directly above the aeration equipment, which easily clogs the aeration equipment.

[0006] Reaction vessel;

[0007] A partition is disposed inside the reaction vessel, the edge of which is connected to the inner wall of the reaction vessel.

[0040] The following reference Figure 1 and Figure 2 This application describes the wastewater organic pollutant purification apparatus and water treatment equipment according to embodiments.

[0041] See Figure 1 and Figure 2As shown, an embodiment of this application provides a wastewater organic pollutant purification device. This wastewater organic pollutant purification device includes: a reaction tank 1, a partition 6, and an aeration device. The partition 6 is disposed inside the reaction tank 1, and its edge is connected to the inner wall of the reaction tank 1. Preferably, the partition 6 is coaxially arranged with the reaction tank 1, dividing the internal space of the reaction tank 1 into upper and lower chambers. The upper chamber is a packing chamber 3, and the lower chamber is an aeration chamber 2. Preferably, the volume of the packing chamber 3 is larger than the volume of the aeration chamber 2. The aeration device is disposed inside the aeration chamber 2 and is used to supply ozone into the aeration chamber 2. The partition 6 has a connecting hole, through which the packing chamber 3 and the aeration chamber 2 are connected. The reaction tank 1 is provided with an inlet 8 and an outlet 10, wherein the inlet 8 is located on the side wall of the aeration chamber 2. The outlet 10 is located on the side wall of the packing chamber 3. The water to be treated flows into the aeration chamber 2 through the inlet 8. After being fully contacted with ozone in the aeration chamber 2, the water flows through the connecting hole to the packing chamber 3 for further treatment. The treated water is then discharged through the outlet 10. As can be seen, the wastewater organic pollutant purification device provided in this embodiment separates the aeration device and the packing material into different chambers. The partition 6 supports the packing material, preventing it from contacting the aeration device or being too close, thus reducing the probability of the packing material clogging the aeration device.

[0042] Specifically, the aeration device includes an air inlet pipe 4 and aeration heads 5. The air inlet pipe 4 passes through the side wall of the aeration chamber 2, with one end outside the reaction tank 1 for connection to an air source, which can be an ozone tank or a pipeline for transporting ozone. The other end of the air inlet pipe 4 is located inside the reaction tank 1, extending radially towards the inner wall of the aeration chamber 2. Multiple aeration heads 5 are spaced apart on the air inlet pipe 4, each capable of spraying ozone into the aeration chamber 2 to ensure sufficient contact and mixing of ozone with the water to be treated. Preferably, the aeration heads 5 are connected to the air inlet pipe 4 via threads. This optimized arrangement of the aeration heads 5 ensures a rapid rise of ozone and shortens the reaction time.

[0043] Furthermore, there are multiple connecting holes, which are spaced apart. Each connecting hole penetrates the upper and lower surfaces of the partition 6. Preferably, all the connecting holes are distributed in a matrix and the edges of the partition 6 are connected to the partition 6, so that the partition 6 has a screen structure. Water in the aeration chamber 2 flows into the packing chamber 3 through each connecting hole.

[0044] Furthermore, this wastewater organic pollutant purification device also includes multiple filter screens 7, each with a filter screen 7 installed in its connecting hole. This allows water in the aeration chamber 2 to flow through the filter screens 7 and into the packing chamber 3. By installing the filter screens 7, water flow can be ensured, and the aeration chamber 2 can be separated from the packing material, preventing the filter media in the packing chamber 3 from falling into the aeration chamber 2. In addition, the filter screens 7 can filter the water as it flows through them.

[0045] Furthermore, this wastewater organic pollutant purification device also includes filter media (not shown in the figure). The filter media are arranged in layers within the filter media chamber 3. Preferably, the filter media has multiple layers. The filter media used in each layer of filter media can be the same or different. Water flowing into the filter media chamber 3 flows through each layer of filter media, effectively filtering out impurities in the water. It should be noted that the filter media used in this embodiment are commonly used filter media in the prior art, and the specific type is not specifically limited in this embodiment.

[0046] Furthermore, the inlet 8 is located at the bottom of the reaction tank 1, specifically at the bottom of the aeration chamber 2. The inlet 8 is equipped with a first flange 9, which is used to connect to the water treatment equipment. The water to be treated flows from bottom to top into the aeration chamber 2 through the first flange 9 and the inlet 8. In the aeration chamber 2, the water comes into full contact with ozone and reacts with the organic molecules in the water to remove organic matter. The water in the aeration chamber 2 flows through the baffle 6 and the filter screen 7 into the packing chamber 3.

[0047] Furthermore, the outlet 10 is located at the top of the reaction tank 1. Specifically, the outlet 10 is located at the top of the packing chamber 3. The outlet 10 is equipped with a second flange 11, which is used to connect to the water treatment equipment. The water flowing into the packing chamber 3 flows through each filter packing and then flows out through the outlet 10. During this process, the multi-layer filter packing fully filters the water.

[0048] Furthermore, the wastewater organic pollutant purification device also includes a sight glass 12, which is disposed on the side wall of the reaction tank 1. Preferably, the sight glass 12 is disposed on the side wall of the packing chamber 3, and the operation inside the reaction tank 1 can be observed through the sight glass 12.

[0049] Furthermore, the wastewater organic pollutant purification device also includes multiple manholes. Preferably, there are three manholes: a first manhole 13, a second manhole 14, and a third manhole 15. The first manhole 13 is located at the top of the reaction tank 1 and is spaced apart from the second flange 11, which facilitates the maintenance and repair of the packing chamber 3 by the staff.

[0050] The second manhole 14 is located on the side wall of the packing chamber 3. The second manhole 14 is located near the bottom of the packing chamber 3 and above the partition 6, which facilitates the maintenance and repair of the partition 6 by the staff.

[0051] The third manhole 15 is provided on the side wall of the aeration chamber 2, which facilitates the maintenance and repair of the aeration chamber 2 and the aeration device by the staff. It should be noted that in this embodiment, a separate maintenance manhole is provided for the aeration chamber 2, so the maintenance and repair of the aeration device can be completed without emptying the packing.

[0052] In use, the wastewater organic pollutant purification device provided in this application allows the water to be treated to enter the aeration chamber 2 of the reaction tank 1 through the first flange 9. Ozone enters through the air inlet pipe 4 and is aerated through the micropores of the aeration head 5, mixing with the water to be treated and reacting with the organic molecules in the water. After the ozone mixes with the water to be treated, it enters the packing chamber 3 of the reaction tank 1 through the filter screen 7 on the baffle 6. The filter screen 7 not only filters out some impurities but also extends the reaction time. Then, the water flows out through the second flange 11.

[0053] In summary, the wastewater organic pollutant purification device provided in this application features a dual-chamber structure design for the reaction tank 1, separating the aeration equipment from the packing material, effectively preventing the packing material from clogging the aeration equipment. Because the aeration equipment is located in a separate chamber, it facilitates replacement and maintenance.

[0054] The embodiments of this application also provide a water treatment device, including the wastewater organic pollutant purification device described in any of the above embodiments, and thus have all the beneficial technical effects of the wastewater organic pollutant purification device, which will not be repeated here.

[0055] The water treatment equipment provided in this application effectively reduces the probability of blockage in the aeration equipment during the ozone reaction stage through the aforementioned wastewater organic pollutant purification device, thereby reducing the failure rate of the wastewater organic pollutant purification device and avoiding affecting the overall operating efficiency of the water treatment equipment.

[0056] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
