Therefore, the features defined as "first", "second", etc. can explicitly or implicitly include one or more of the features. In the description of the present application, the meaning of "multiple" is at least two, such as two, three, etc., unless otherwise specifically limited.

[0033] The present application will be further described in detail below in conjunction with the drawings and specific embodiments.

[0034] As shown in Figure 1 The industrial wastewater advanced treatment device of the present application includes a shell 1, which is a hollow cylindrical structure, which can be a square cylindrical structure or a circular cylindrical structure, as long as it meets the use. The shell 1 is provided with an adsorption reaction zone and a membrane filtration zone. The adsorption reaction zone is provided with a plurality of reaction units stacked vertically. The reaction unit includes a porous ceramsite 2 for adsorbing water flow. The adsorption reaction zone is provided with a wastewater inlet. The bottom layer of the adsorption reaction zone is provided with a water pump 6 for circulating reaction of water flow. The adsorption reaction zone further includes a circulating pipeline 5 (the water pump 6 is installed on the circulating pipeline 5, and the water pump 6 can be a submersible pump installed at the bottom layer of the adsorption reaction zone, or a conventional water pump installed outside the shell). The two ends of the circulating pipeline 5 are respectively connected to the upper and lower ends of the adsorption reaction zone.

[0035] That is, after the wastewater enters the adsorption reaction zone, it will flow through the porous ceramsite during the flow in the adsorption reaction zone. The porous ceramsite of the present application is mainly prepared from phosphate rock flotation tailings. The porous ceramsite can adsorb and react with phosphorus in water, effectively adsorb phosphate in water, and achieve the effect of water purification. Under the action of the water pump 6, the entering wastewater flows through the porous ceramsite 2, then undergoes a round of adsorption treatment, and then enters the circulating pipeline 5 under the pressure boosting effect of the booster pump 6. At this point, the entering wastewater in the adsorption reaction zone undergoes a second round of adsorption treatment, and the cycle is repeated until most of the impurities in the water are adsorbed and treated by the porous ceramsite.

[0036] The membrane filtration zone is provided with a plurality of filter units stacked vertically. The filter unit includes a ceramic membrane 3 for filtering water flow. The membrane filtration zone is provided with a clean water outlet 4. The membrane filtration zone and the adsorption reaction zone are provided with a communication pipeline 7 for introducing purified water from the adsorption reaction zone to the membrane filtration zone after the adsorption purification is completed.

[0037] The membrane filtration zone is used to filter the water purified by the porous ceramic particles 2. In this application, the membrane filtration zone primarily uses a ceramic membrane 3 for water filtration. However, other device structures can also be used in practical applications, as long as the required specifications are met. The ceramic membrane 3 of this application can filter suspended solids in the water. By setting multiple filtration units, multiple filtration processes can be performed. Each filtration unit can be designed differently, i.e., with different filter particle sizes. Lower filtration units may have larger filter particle sizes, while upper filtration units may have smaller filter particle sizes, or other designs can be used to filter different impurities, ensuring that the water quality flowing out of the purified water outlet fully meets the requirements.

[0038] In actual use, wastewater enters the adsorption reaction zone from the wastewater inlet. The wastewater flows through multiple reaction units in sequence for adsorption treatment by porous ceramic particles 2. Then, under the action of water pump 6, it is driven into the circulation pipe 5. The circulation pipe 5 discharges the water to the other side of the adsorption reaction zone for secondary treatment. The cycle repeats until the wastewater reaches the required purification level after multiple treatments.

[0039] The adsorption reaction zone discharges the purified water into the membrane filtration zone. The water entering the membrane filtration zone passes through multiple filtration units in sequence for filtration treatment, and finally the water flowing out of the purified water outlet meets the discharge standards.

[0040] In some embodiments of this application, the shell structure described above has been optimized, specifically, as follows: Figure 1 As shown, the housing 1 in this embodiment is provided with an intermediate plate 8, which is a closed plate used to divide the housing 1 into two mutually isolated areas, namely the adsorption reaction area at the top and the membrane filtration area at the bottom.

[0041] In practical applications, a parallel arrangement can also be used. In this embodiment, a stacked arrangement is used, with the adsorption reaction zone above the membrane filtration zone. This design facilitates water flow, making it easier for wastewater to enter the shell for treatment and for purified water to flow out of the shell.

[0042] In other embodiments of this application, the above-mentioned circulation pipes and connecting pipes have been optimized, specifically, as follows: Figure 1 As shown, in this embodiment, the other end of the connecting pipe 7 is connected to the circulation pipe 5 via a tee. A first valve 9 is provided on the connecting pipe 7 to control the opening and closing of the connecting pipe 7, and a second valve 10 is provided on the circulation pipe 5 to control the opening and closing of the circulation pipe 5.

[0043] In other words, this embodiment uses a set of water pumps 6 to realize the flow of water in the entire industrial wastewater deep treatment device, including driving the water flow to circulate in the adsorption reaction zone to achieve the effect of circulation treatment, and also includes the operation of discharging the water in the adsorption reaction zone into the membrane filtration zone.

[0044] In actual use, the second valve 10 is closed, the first valve 9 is opened, and the water pump 6 is started. The water pump 6 drives the water in the adsorption reaction zone to flow. Wastewater enters the adsorption reaction zone from the wastewater inlet and passes through the porous ceramic particles 2 of multiple reaction units from bottom to top. The porous ceramic particles 2 adsorb and purify the wastewater. Finally, the wastewater enters the top of all reaction units, and the water pump 6 pressurizes this water into the circulation pipe 5. Then, the water is discharged to the bottom of all reaction units through the circulation pipe 5 for secondary purification. This process is repeated to circulate the water in the adsorption reaction zone, achieving the effect of circulation treatment.

[0045] After a period of reaction, the water in the adsorption reaction zone reaches the purification effect. The first valve 9 is closed, the second valve 10 is opened, and the water pump 6 is started. The water pump 6 discharges the purified water in the adsorption reaction zone into the lower part of all the filter units in the membrane filtration zone through the three-way valve and connecting pipe. The water entering the membrane filtration zone flows from bottom to top through multiple filter units. After multiple filtration processes, it finally enters the upper part of all the filter units. At this time, the water that has undergone multiple filtration processes can be discharged through the clean water outlet on the membrane filtration zone for use as drinking water.

[0046] In a further embodiment of this application, the above-described reaction unit structure has been optimized, specifically, as follows: Figure 1 As shown, the reaction unit includes two first partitions 11 that are vertically spaced apart. The space between the two first partitions 11 is filled with porous ceramic particles 2. Multiple small holes are evenly distributed on the first partitions 11.

[0047] Two first partition plates 11 and porous ceramic particles 2 filled between the two first partition plates 11 form a set of reaction units. Small holes are evenly distributed on the first partition plates 11. The first partition plates 11 are arranged horizontally in the shell 1. Water can pass through the small holes and fully contact the porous ceramic particles 2 between the two first partition plates 11. The small holes evenly distributed on the first partition plates 11 can play a role in uniformly diverting the water, so that the water can flow fully through the porous ceramic particles between the first partition plates 11, thereby improving the adsorption treatment effect.

[0048] To facilitate the disassembly and installation of the reaction unit, such as Figure 1 As shown, in this embodiment, a first column 12 arranged vertically is installed on the first partition 11, and the first columns 12 on adjacent first partitions 11 overlap in the vertical direction. The first column 12 located at the outermost upper and lower ends in the adsorption reaction zone is fixed to the shell 1 so that the reaction unit is detachably connected to the shell 1.

[0049] The adjacent first partition 11 is vertically supported by the first column 12. On the one hand, the first column 12 can provide vertical support for the first partition 11 and the porous ceramic particles 2. On the other hand, the first column 12 can prevent the two first partitions 11 in the same reaction unit from pressing the porous ceramic particles 2 between them. This allows the porous ceramic particles 2 between the two first partitions 11 to be in a relatively loose state, which facilitates water flow and more sufficient contact with the porous ceramic particles 2, thereby further improving the adsorption reaction effect and treatment efficiency.

[0050] The lower end of the first column 12, located at the bottom of all reaction units, is supported on the intermediate plate 8, while the upper end of the first column 12, located at the top of all reaction units, is supported on the top plate of the housing 1. The edge of the first partition 11 in the adsorption reaction zone abuts against the inner edge of the housing 1. The housing 1 restricts the horizontal movement of the first partition 11, and the first column 12 restricts the vertical movement of the first partition 11. Therefore, the first partition 11 can be easily confined within the housing 1. When it is necessary to disassemble the reaction unit, the top plate of the housing 1 is opened, and the first partition 11, the first column 12, and the porous ceramic particles 2 are removed from the housing 1 one by one. The entire disassembly operation is very convenient, and replacement and cleaning are very easy.

[0051] In a preferred embodiment of this application, the above-described filtering unit structure has been optimized, specifically, as follows: Figure 1 As shown, the filter unit includes two second partitions 13 that are vertically spaced apart, with a ceramic membrane 3 uniformly filled between the two second partitions 13, and multiple small holes are uniformly distributed on the second partitions 13.

[0052] Two second partitions 13 and a ceramic membrane 3 filled between the second partitions 13 form a filter unit. The small holes evenly distributed on the second partitions 13 facilitate water flow, so that the water entering the membrane filtration zone can flow evenly through the layered filtration structure formed by the ceramic membrane 3, achieving a good filtration effect.

[0053] In addition, a second column 14 arranged vertically is installed on the second partition 13 in this embodiment. The second columns 14 on the second partition 13 overlap in the vertical direction. The outermost second column 14 located at the upper and lower ends of the membrane filtration area is fixed to the housing 1 so that the filtration unit is detachably connected to the housing 1.

[0054] Similarly, the second column 14 serves a similar function to the first column 12 described above. The second column 14 provides vertical support for the second partition 13, and the housing 1 provides horizontal restraint for the second partition 13, thus confining the second partition 13 and the intermediate ceramic membrane 3 within the housing 1. The upper end of the second column 14, located at the top of all filter units, abuts against the lower end face of the intermediate plate 8, while the lower end of the second column 14, located at the bottom of all filter units, abuts against the bottom plate of the housing 1. When disassembly is required, simply open the intermediate plate 8 and then disassemble the second partition 13, the second column 14, and the ceramic membrane 3 in sequence. The disassembly operation is very simple.

[0055] In this embodiment, the second column 14 is arranged on the outside of the second partition 13 of each filter unit. That is, the second column 14 is not set between adjacent second partitions 13 in the same filter unit. This is because the filtration operation requires the ceramic membrane 3 to be tightly filled between the two second partitions 13. Not setting the second column 14 between the two second partitions 13 can prevent the ceramic membrane 3 from flowing between the two second partitions 13, and the filtration effect is better in actual use.

[0056] In actual use, the industrial wastewater deep treatment device of this application closes the second valve 10, opens the first valve 9, and starts the water pump 6. The water pump 6 drives the water in the adsorption reaction zone to flow. Wastewater enters the adsorption reaction zone from the wastewater inlet and passes through the porous ceramic particles 2 of multiple reaction units from bottom to top. The porous ceramic particles 2 adsorb and purify the wastewater. Finally, the wastewater enters the top of all reaction units, and the water pump 6 drives this part of the water into the circulation pipe 5. Then, it is discharged to the bottom of all reaction units through the circulation pipe 5 for secondary purification. This process is repeated to circulate the water in the adsorption reaction zone, achieving the effect of circulation treatment.

[0057] After a period of reaction, the water in the adsorption reaction zone reaches the purification effect. Close the first valve 9, open the second valve 10, and start the water pump 6. The water pump 6 discharges the purified water in the adsorption reaction zone into the lower part of all the filter units in the membrane filtration zone through the three-way valve and connecting pipe. The water entering the membrane filtration zone flows from bottom to top through multiple filter units. After multiple filtration processes, it finally enters the upper part of all the filter units. At this time, the water that has undergone multiple filtration processes can be discharged through the clean water outlet on the membrane filtration zone for use as drinking water.

[0058] If the filter unit or reaction unit becomes clogged and needs cleaning after a period of use, the top plate of the housing 1 can be removed, and the first partition 11, the first column 12, the porous ceramic particles 2, the intermediate plate 8, the second column 14, the second partition 13 and the ceramic membrane 3 can be taken out from the housing 1 in sequence. The housing 1 and the porous ceramic particles 2 and the ceramic membrane 3 can be cleaned. After cleaning, they can be reinstalled into the housing 1 for use.

[0059] To facilitate the use of the industrial wastewater deep treatment device of this application, an intelligent numerical control display can be arranged on the outside of the housing 1. The display is equipped with an intelligent control system. The intelligent control system controls the water pump 6, the first valve 9, and the second valve 10. The control system controls the water pump 6, the first valve 9, and the second valve 10 to achieve different needs.
