Description

Technical Field

[0001] This application relates to the field of water treatment technology, and in particular to a water treatment structure. Background Technology

[0002] Excessive growth of algae and bacteria produces a large number of secondary metabolites, making the odor problem of water increasingly prominent. The most common odor substances in water are geosmin and 2-methylisoborneol, which cause the earthy smell. Geosmin and 2-methylisoborneol are mainly metabolic products of actinomycetes and cyanobacteria. Although their effects on human health are not yet clear, they reduce the quality of drinking water, causing complaints from users and doubts about water quality.

[0003] In existing technologies, ozone and membrane separation are used to remove pollutants from water, but these processes produce bromate byproducts and have low efficiency.

[0004] Therefore, it is necessary to propose a water treatment structure to improve water treatment efficiency, which has become an important technical problem that urgently needs to be solved. Utility Model Content

[0005] This application provides a water treatment structure designed to address the problems in existing technologies that use ozone and membrane separation to remove pollutants from water, but generate byproducts such as bromate during the treatment process and have low treatment efficiency.

[0006] To achieve the above objectives, this application proposes a water treatment structure, comprising: a treatment cylinder; end caps, with end caps provided at both ends of the treatment cylinder; a wastewater inlet, with the wastewater inlet located within the treatment cylinder; an ultrafiltration support, with the ultrafiltration support disposed within the end caps; a hollow fiber bundle, with a hollow fiber bundle disposed between two ultrafiltration supports; an adsorber, with an adsorber disposed at the wastewater inlet; and a treated water outlet, with the treated water outlet located at the end cap at the bottom.

[0007] In some embodiments, the adsorber includes: a right shell connected to a sewage inlet; a left shell connected to the right shell; a sponge layer disposed in both the right and left shells; an activated carbon layer disposed in the left shell; and a zeolite layer disposed in the right shell.

[0008] In some embodiments, the activated carbon layer includes: a cylindrical section; two filter screens disposed at opposite ends of the cylindrical section, with activated carbon disposed between the two filter screens.

[0009] In some embodiments, the system further includes: a first seal, wherein the cylindrical section is disposed between the left and right housings; and a second seal, wherein the right and left housings are disposed between the right and left housings.

[0010] In some embodiments, it further includes: a backflush, wherein the backflush is provided with an end cap at its top.

[0011] In some embodiments, it further includes: a clamp, wherein the processing cylinder and the end cap are connected together by the clamp.

[0012] This application proposes a water treatment structure, including: a treatment cylinder; end caps at both ends of the treatment cylinder; a wastewater inlet located within the treatment cylinder; an ultrafiltration support inside the end caps; a hollow fiber bundle between the two ultrafiltration supports; an adsorber located at the wastewater inlet; and a treated water outlet located at the bottom end cap. Wastewater flows into the wastewater inlet through the adsorber and then into the treatment cylinder, where it undergoes pressure ultrafiltration. The treated water is then discharged from the treated water outlet. By organically combining the physical adsorption of the adsorber with the physical retention of the hollow fiber bundles, this structure can effectively remove particulate matter, organic pollutants, ammonia nitrogen, insects, algae, bacteria, and viruses from the water, while also efficiently removing algal toxins and odor-causing substances from high-algae water. This ensures that the levels of algal toxins and odor-causing substances in the treated effluent meet the requirements of the "Standards for Drinking Water Quality," effectively improving water treatment efficiency, reducing water pollution, and enhancing the safety of drinking water for urban residents.

[0019] See Figure 1 , Figure 3 , Figure 4 and Figure 5 As shown, this application proposes a water treatment structure, including: a treatment cylinder 5; end caps 2, with end caps 2 at both ends of the treatment cylinder 5; a wastewater inlet 6, with the wastewater inlet 6 disposed in the treatment cylinder 5; an ultrafiltration support 12, with the ultrafiltration support 12 disposed inside the end cap 2; a hollow fiber bundle 11, with a hollow fiber bundle 11 disposed between two ultrafiltration supports 12; an adsorber 7, with the adsorber 7 disposed in the wastewater inlet 6; and a treated water outlet 3, with the treated water outlet 3 disposed at the bottom end of the end cap 2.

[0020] The treatment cylinder 5 serves as the structural foundation of a water treatment structure, and all other structures within it are directly or indirectly mounted onto the treatment cylinder 5. An ultrafiltration support 12 is positioned at the bottom of the end cap 2, abutting against the end of the treatment cylinder 5, with a waterproof adhesive placed between them. Hollow fiber bundles 11 are glued to the ultrafiltration support 12, intercepting pollutants in the wastewater. The treated water is then discharged from the treated water outlet 3.

[0021] Among them, the adsorber 7 is the core structure of a water treatment system. The adsorber 7 uses its porous structure to adsorb and fix toxins, heavy metals and chemicals in wastewater, thereby purifying the water quality. In addition, the adsorber 7 can also effectively inhibit membrane fouling and improve water treatment efficiency.

[0022] In this embodiment, the treatment cylinder 5 is also provided with a pressure outlet 4, which is used to maintain the stability of the water pressure inside the treatment cylinder 5.

[0023] Specifically, wastewater flows into wastewater inlet 6 through adsorber 7 and then into treatment cylinder 5, where it undergoes pressure ultrafiltration. The treated water is then discharged from treated water outlet 3. By organically combining the physical adsorption of adsorber 7 with the physical retention of hollow fiber bundles 11, this process effectively removes particulate matter, organic pollutants, ammonia nitrogen, insects, algae, bacteria, and viruses from the water, while also efficiently removing algal toxins and odor-causing substances from high-algae water. This ensures that the levels of algal toxins and odor-causing substances in the treated effluent meet the requirements of the "Standards for Drinking Water Quality." This effectively improves water treatment efficiency, reduces water pollution, and enhances the safety of drinking water for urban residents.

[0024] See Figure 1 , Figure 3 , Figure 4 and Figure 5As shown, in some embodiments, the adsorber 7 includes: a right shell 71 connected to the sewage inlet 6 via a double-ended connecting pipe; a left shell 77 connected to the right shell 71 via a screw connection; a sponge layer 78 disposed within both the right and left shells 71; and a sponge layer 78 disposed at the left end of the left shell 77 and the right end of the right shell 71. The sponge layer 78 is used for preliminary removal of large particulate pollutants, reducing the probability of clogging of the subsequent activated carbon layer 75 and zeolite layer 72. An activated carbon layer 75 is disposed within the left shell 77; the activated carbon layer 75 adsorbs and fixes toxins, heavy metals, and chemicals in the sewage through its porous structure. A zeolite layer 72 is disposed within the right shell 71. Zeolite layer 72 possesses adsorption, ion exchange, catalytic, acid resistance, and thermal stability, while also having a large specific surface area. It can effectively remove organic matter, ammonia nitrogen, heavy metal ions, fluorine, and phosphorus, and will not cause secondary pollution to the environment during use and treatment.

[0025] In this embodiment, the activated carbon layer 75 is made of biological activated carbon, which removes organic pollutants from water by immobilizing microorganisms on the surface of activated carbon, combining adsorption and biodegradation in a synergistic effect. The zeolite layer 72 is made of zeolite. By organically combining the physical adsorption of activated carbon, the adsorption and ion exchange of zeolite, the biodegradation of biological activated carbon, and the physical retention of the hollow fiber bundles 11, it is possible to efficiently remove particulate matter, organic pollutants, ammonia nitrogen, insects, algae, bacteria, and viruses from water, while also effectively removing algal toxins and odor-causing substances from high-algae water.

[0026] See Figure 3 and Figure 4 As shown, in some embodiments, the activated carbon layer 75 includes: a cylindrical section 73; two filter screens 76, which are respectively disposed at both ends of the cylindrical section 73, with activated carbon disposed between the two filter screens 76. The two ends of the cylindrical section 73 are connected to the filter screens 76 by adhesive bonding. The activated carbon layer 75 can be removed for cleaning.

[0027] See Figure 3 and Figure 4 As shown, in some embodiments, the system further includes: a first seal 74, which is disposed between the cylindrical section 73 and the left shell 77, to improve the sealing between the activated carbon layer and the left shell 77, preventing wastewater from flowing into subsequent treatment processes without being adsorbed by the activated carbon layer; and a second seal 79, which is disposed between the right shell 71 and the left shell 77, to improve the sealing between the right shell 71 and the left shell 77, preventing wastewater leakage. Both the first seal 74 and the second seal 79 are O-rings.

[0028] In this embodiment, the structure of the zeolite layer 72 is the same as that of the activated carbon layer, that is, the zeolite layer 72 also includes a cylindrical section 73 and two filter screens 76, with zeolite filling between the two filter screens 76, and a first sealing element 74 between the cylindrical section 73 of the zeolite layer 72 and the right shell 71.

[0029] See Figure 1 and Figure 3 As shown, in some embodiments, it further includes: a backflush port 1, with an end cap 2 at its top. Backflush is necessary to clean the hollow fiber bundles 11 when membrane fouling is severe.

[0030] See Figure 1 , Figure 2 , Figure 3 and Figure 5 As shown, in some embodiments, the device further includes a clamp, connecting the processing cylinder 5 and the end cap 2 together. The clamp includes two semi-circular retaining rings 9, each with an upper clamping ring 91 and a lower clamping ring 92. Both the processing cylinder 5 and the end cap 2 are partially located between the upper clamping ring 91 and the lower clamping ring 92. The two semi-circular retaining rings 9 are connected together by bolts 10 and locking nuts 8, thereby forming the connection between the processing cylinder 5 and the end cap 2.
