Description

Technical Field

[0001] The invention belongs to the technical field of surface water processing and treatment, and in particular relates to a comprehensive surface water treatment device. Background Art

[0002] Under the severe situation of global water shortage, surface water treatment and purification technology faces unprecedented challenges. Although traditional surface water treatment methods such as coagulation, sedimentation, filtration and disinfection can purify water and remove some impurities and pathogens to a certain extent, their inherent limitations and defects are gradually emerging, making it difficult to meet the urgent needs of modern society for high-quality and high-safety water resources.

[0003] First, as an important part of traditional water treatment technology, the effect of coagulation and sedimentation is affected by many factors. The selection and dosage of coagulants, raw water quality, mixing and reaction conditions will directly affect the coagulation effect. However, the coagulation and sedimentation process is often unable to remove tiny suspended solids and soluble pollutants. These tiny pollutants are difficult to be effectively removed by a simple coagulation and sedimentation process due to their small particle size and high stability, resulting in the water quality after treatment still containing a certain amount of residual pollutants.

[0004] Secondly, the filtration process, as a means of further purifying water quality, also faces many challenges. As the use time of traditional filtration methods increases, the filter material is easily clogged, resulting in a decrease in flux. This not only increases operating costs, but may also affect the stability of water quality. In addition, the effect of the filtration process on the removal of soluble pollutants is relatively limited.

[0005] Furthermore, the disinfection process, as a key link in ensuring water quality safety, also has problems that cannot be ignored. Although the traditional chlorine disinfection method can effectively kill bacteria, viruses and other pathogens in water, it may produce harmful byproducts such as chloroform during use, posing a potential threat to human health.

[0006] At the same time, chlorine disinfection is not ideal for killing some chlorine-resistant pathogens, such as Cryptosporidium and Giardia. Therefore, while pursuing efficient sterilization, how to reduce the production of disinfection by-products has become an urgent problem to be solved.

[0007] Finally, traditional surface water treatment methods are unable to cope with complex water quality conditions. With the rapid advancement of industrialization and urbanization, the quality of surface water is becoming increasingly complex, and the types and concentrations of pollutants are increasing. Traditional treatment processes are often unable to cope with such complex water quality conditions, resulting in unstable treatment effects and difficulty in ensuring the quality of effluent water.

The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0032] The embodiment of the present invention provides a comprehensive surface water treatment device, such as Figure 1-6 As shown, it includes a recovery tube 1 and a treatment pool 2; the top of the recovery tube 1 is connected to an exhaust pipe 3 and a recovery conduit 4 connected to its inner cavity; the recovery conduit 4 is provided with a first one-way valve 5; three filter screens 6 are arranged parallel to the inner position of the recovery tube 1, and the filter screens 6 are arranged at an angle; wherein, a cleaning box 7 is arranged on the side with a higher inclination slope adjacent to several of the filter screens 6; electric push rods 8 are arranged in several of the cleaning boxes 7; receiving blocks 9 are arranged at the telescopic ends of several of the electric push rods 8; and cleaning brooms 10 are arranged on the bottom sides of several of the receiving blocks 9, and the cleaning brooms 10 are connected to the corresponding filter screens 6. The inclination slope is adapted; the sides with lower inclination slopes adjacent to several of the filter screens 6 are connected with slag discharge ports 11; the external positions of the three slag discharge ports 11 are connected with the same slag collecting channel 12; a transverse connecting rod 13 is arranged at the lower position of the inner cavity of the recovery cylinder 1, and the transverse connecting rod 13 rotates with the recovery cylinder 1; a stirring blade 14 is arranged on the outer side of the transverse connecting rod 13; a servo motor 15 is arranged on the outer side of the recovery cylinder 1, and the output end of the servo motor 15 is fixedly connected with the end key of the transverse connecting rod 13; a medicine feeding port 16 connected with its inner cavity is provided on the side of the recovery cylinder 1 away from the servo motor 15.

[0033] It should be noted that the traditional water treatment process has obvious deficiencies in removing tiny suspended matter, soluble pollutants and ensuring water quality safety, which is specifically manifested in that the coagulation sedimentation and filtration processes have limited removal effects on tiny pollutants, and harmful by-products are easily produced during the disinfection process. At the same time, it is difficult to effectively kill chlorine-resistant pathogens, thus affecting the overall purification and safety of water quality. This solution not only ensures the continuous high efficiency of the filtration process and the long life of the filter 6 through the layered filtration and automatic cleaning mechanism of the three inclined filter screens 6, thereby significantly improving the initial purification effect of water treatment; it also accelerates the chemical reaction and physical precipitation process through the coordination of precise dosing and stirring systems, laying a solid foundation for subsequent treatment; in addition, the multi-stage purification system in the treatment pool 2, especially the application of ultrafiltration membrane technology, ensures that the water quality meets high standards and ensures water quality safety; finally, combined with the gas treatment system, it effectively avoids secondary pollution and maintains the cleanliness of the treatment environment and the air quality.

[0034] Specifically, in this embodiment, the scheme mainly includes a recovery drum 1 and a treatment pool 2; surface water first enters the recovery drum 1 through a recovery conduit 4, and a first one-way valve 5 equipped on the recovery conduit 4 ensures the one-way entry of the water flow, effectively preventing the backflow phenomenon; once entering the recovery drum 1, the water flow immediately encounters three carefully designed inclined filter screens 6, which are arranged at a specific angle, and perform preliminary and efficient filtration of impurities, suspended matter, etc. in the water flow, and successfully intercept larger particles on the net; as the filtration continues, a layer of impurities will inevitably accumulate on the filter screen 6; in order to maintain the filtration efficiency, the electric push rod 8 provided in the cleaning box 7 is automatically started at this time; the electric push rod 8 drives the receiving block 9 connected to its telescopic end and the cleaning broom 10 equipped on the bottom side to slowly move along the inclined slope of the filter screen 6; the shape of the cleaning broom 10 perfectly matches the inclined slope of the filter screen 6, ensuring that the impurities are thoroughly and effectively removed;

[0035] The impurities and particles swept down naturally slide to the lower side along the slope of the filter screen 6 under the action of gravity; then, these impurities and particles are discharged through the slag discharge port 11 arranged on the lower side of the filter screen 6, and the three slag discharge ports 11 are finally gathered into the same slag collection channel 12, which greatly facilitates the subsequent centralized collection and treatment work;

[0036] The water flow after preliminary filtration continues to flow downward to the lower area of ​​the inner cavity of the recovery tube 1; at this time, through the special drug feeding port 16 on the side of the recovery tube 1, the operator can accurately add an appropriate amount of treatment agent into the water, such as disinfectant for killing bacteria and viruses, and flocculant to help suspended matter to condense and settle faster; at the same time, the transverse connecting rod 13 located at the lower part of the inner cavity of the recovery tube 1 starts to rotate under the powerful power of the servo motor 15; the stirring blades 14 densely distributed on the outside of the connecting rod rotate rapidly, which not only promotes the full mixing of suspended matter and agents in the water, but also accelerates the occurrence of chemical reactions and physical precipitation processes, thereby significantly improving the efficiency and effect of subsequent water treatment.

[0037] In a further preferred embodiment of the present invention, Figure 1-2 As shown, the lower position of the recovery tube 1 is connected to a first water pipe 17 connected to its inner cavity, one end of the first water pipe 17 is connected to a first pump body 18, and the other end of the first pump body 18 is connected to the treatment pool 2.

[0038] In this embodiment, surface water is guided to the first pump body 18 through the first water pipe 17. The first pump body 18 acts as a power source and generates suction or pressure during operation to draw water out of the recovery drum 1 and transport it to the treatment tank 2. Once the water enters the treatment tank 2, a more in-depth water treatment process can be carried out.

[0039] In a further preferred embodiment of the present invention, Figure 1-4 As shown, the treatment pool 2 is divided into two independently arranged first treatment chambers 20 and second treatment chambers 21 by a vertical plate 19, wherein a group of parallel grids 22 are arranged in the first treatment chamber 20, and an ultraviolet sterilization lamp 23 is arranged on one side of the grid 22 adjacent to the second treatment chamber 21.

[0040] In this embodiment, after the water flow that has undergone preliminary treatment enters the first treatment chamber 20, it first encounters the grid 22; the main function of the grid 22 is to intercept and remove the larger particles or suspended matter remaining in the water, effectively preventing these impurities from further flowing to the subsequent treatment stage; at the same time, the setting of the grid 22 slows down the flow rate of the water flow, so that the contact time between the water and the grid 22 can be prolonged. This process not only enhances the filtering effect, but also improves the efficiency of impurity removal;

[0041] The clarity of the water after being fully filtered by the grid 22 is improved to a certain extent; then, before flowing into the second processing chamber 21, the water will pass through the ultraviolet sterilization lamp 23 area; in this area, the ultraviolet sterilization lamp 23 makes full use of its powerful sterilization ability to efficiently and comprehensively kill bacteria, viruses and other microorganisms in the water; this step is not only a key link in ensuring water quality safety, but also can significantly reduce the content of microorganisms in the water, providing a more reliable guarantee for subsequent water treatment.

[0042] In a further preferred embodiment of the present invention, Figure 5 As shown, a quartz sand filter cartridge 24, an activated carbon filter cartridge 25 and an ultrafiltration membrane cartridge 26 are sequentially arranged in the second treatment chamber 21, and the quartz sand filter cartridge 24, the activated carbon filter cartridge 25 and the ultrafiltration membrane cartridge 26 are all provided with an inlet and a discharge port connected to their inner cavities. The discharge port of the quartz sand filter cartridge 24 is connected to the inlet of the activated carbon filter cartridge 25 through a second water conduit 35, and the discharge port of the activated carbon filter cartridge 25 is connected to the inlet of the ultrafiltration membrane cartridge 26 through the second water conduit.

[0043] In this embodiment, after the preliminary filtration in the first treatment chamber 20, the clarity of the water has been improved; then, the water first flows into the quartz sand filter cartridge 24, which is filled with quartz sand particles of moderate particle size; the tiny gaps between the quartz sand particles become an effective barrier for further intercepting and removing tiny suspended matter, colloidal particles and some organic matter in the water; as the water flows slowly, these impurities are gradually trapped in the quartz sand layer, and the water that has been preliminarily purified continues to flow downward and enters the activated carbon filter cartridge 25;

[0044] The activated carbon filter cartridge 25 is filled with activated carbon particles with strong adsorption capacity. The surface of these activated carbon particles is covered with tiny pores, which can adsorb and remove harmful substances such as organic matter, residual chlorine, unpleasant odors and some heavy metal ions in the water. When water passes through the activated carbon layer, it is fully in contact with the activated carbon particles, and the harmful substances are effectively adsorbed on the surface of the particles, thereby achieving further purification and improvement of water quality.

[0045] Finally, the water treated by the activated carbon filter cartridge 25 is guided to the ultrafiltration membrane cartridge 26 through the second water conduit 35; inside the ultrafiltration membrane cartridge 26, high-precision ultrafiltration membrane elements are installed; these ultrafiltration membrane elements have extremely small pore sizes and can intercept and remove tiny impurities such as bacteria, viruses, colloidal particles and most soluble solids in the water; under the action of the pressure difference, clean water molecules and some small molecular solutes can smoothly pass through the ultrafiltration membrane and enter the other side of the membrane to become high-quality purified water.

[0046] In a further preferred embodiment of the present invention, Figure 1-5As shown, one end of the second water conduit 35 adjacent to the quartz sand filter cartridge 24 extends to the lower position of the first processing chamber 20 , the discharge port of the ultrafiltration membrane cartridge 26 is connected to the water outlet pipe 27 , and a plurality of second one-way valves 28 are arranged on the second water conduit 35 .

[0047] In this embodiment, one end of the second water conduit 35 extends to the lower position of the first treatment chamber 20, ensuring that the water that has undergone preliminary treatment can smoothly flow into the quartz sand filter cartridge 24, and the purified water is discharged through the outlet pipe 27 connected to the outlet of the ultrafiltration membrane cartridge 26 for subsequent use or discharge.

[0048] In a further preferred embodiment of the present invention, Figure 1-6 As shown, a mounting frame 29 is provided at an upper position on one side of the treatment pool 2 adjacent to the first treatment chamber 20, an adsorption hood 30 is provided on the bottom side of the mounting frame 29, a fan 31 and a purification box 32 are provided at the top position of the mounting frame 29, one end of the fan 31 is connected to the adsorption hood 30, and the other end of the fan 31 is connected to the purification box 32, and a plurality of activated carbon filters 33 are provided in the purification box 32.

[0049] In this embodiment, once harmful gases, odors and other pollutants are generated in the treatment pool 2, these pollutants will be immediately captured and collected by the adsorption cover 30. Subsequently, the fan 31 is activated, and its strong suction force causes the polluted air in the adsorption cover 30 to be quickly sucked in and transported to the purification box 32; the activated carbon filter 33 arranged in the purification box 32 can efficiently adsorb harmful substances and odors in the air.

[0050] In a further preferred embodiment of the present invention, Figure 3-4 As shown, the apertures of the three filter screens 6 are gradually reduced from top to bottom.

[0051] In this embodiment, filters with different pore sizes can filter impurities of different sizes. The upper large-pore filter first intercepts larger particles and suspended matter, the middle filter further removes medium-sized impurities, and the lower small-pore filter can effectively capture and remove tiny particles, colloids, bacteria, etc. This layered filtration method ensures that each layer can exert its maximum filtration efficiency.

[0052] In a further preferred embodiment of the present invention, Figure 5 As shown, the filter mesh aperture of the grid mesh 22 adjacent to one side of the second processing chamber 21 is smaller than the filter mesh aperture of the other grid mesh 22 .

[0053] In this embodiment, by using a large-aperture filter in the pre-stage, the risk of blockage can be reduced, ensuring that impurities in the water flow are effectively intercepted, thereby keeping the water flow clean and smooth, and helping to reduce the decrease in flow rate and increase in energy consumption caused by the accumulation of impurities.

[0054] In a further preferred embodiment of the present invention, Figure 3-4 As shown, a plurality of through slots 34 for the electric push rods 8 to pass through are formed on one side of the recycling cylinder 1 adjacent to the plurality of cleaning boxes 7 .

[0055] In this embodiment, the design of the through slot 34 enables the electric push rod 8 to directly pass through the recovery drum 1 without requiring additional space to install the push rod. This compact structural design helps save space and makes the entire device or system more compact and efficient.

[0056] Working principle: When the present invention is used, surface water first enters the recovery drum 1 in one direction through the recovery conduit 4 equipped with the first one-way valve 5, which effectively prevents the backflow phenomenon; after entering the recovery drum 1, the water flow immediately encounters three inclined filter screens 6, which are arranged at a specific angle to preliminarily and efficiently filter out impurities and suspended matter in the water flow. At the same time, the layered filtration method ensures that each layer can exert its maximum filtration efficiency;

[0057] As the filtration continues, impurities inevitably accumulate on the filter screen 6; at this time, the electric push rod 8 in the cleaning box 7 automatically starts, driving the receiving block 9 and the cleaning broom 10 connected to its telescopic end to slowly move along the inclined slope of the filter screen 6, thoroughly and effectively removing the impurities; the swept impurities and particulate matter naturally slide to the lower side of the filter screen 6 under the action of gravity, and are discharged through the slag discharge port 11, and finally gathered in the slag collection channel 12, which is convenient for subsequent centralized collection and treatment;

[0058] The water flow after preliminary filtration continues to flow downward to the lower area of ​​the inner cavity of the recovery cylinder 1; here, the operator adds treatment agents, such as disinfectants and flocculants, through the feeding port 16 to kill bacteria and viruses and help the suspended matter to condense and precipitate; at the same time, the servo motor 15 drives the horizontal connecting rod 13 at the lower part of the inner cavity of the recovery cylinder 1 to rotate, and the stirring blade 14 on the outer side of the connecting rod rotates rapidly, promoting the full mixing of the suspended matter and the agent, accelerating the chemical reaction and physical precipitation process, and improving the subsequent water treatment efficiency;

[0059] Subsequently, the water flow after preliminary treatment is guided to the first pump body 18 through the first water conduit 17. The pump body acts as a power source to pump out the water flow and transport it to the treatment pool 2 for further treatment. In the treatment pool 2, the water flow first enters the first treatment chamber 20, encounters the grid 22 to intercept and remove the remaining larger particles or suspended matter, and at the same time slows down the water flow velocity, thereby improving the filtering effect and impurity removal efficiency.

[0060] The water filtered by the grid 22 has improved clarity and then enters the ultraviolet sterilization lamp 23 area, which effectively kills bacteria, viruses and other microorganisms in the water, ensuring water quality safety and reducing the content of microorganisms; after that, the water flows through the quartz sand filter cartridge 24 and the activated carbon filter cartridge 25 in turn to further remove harmful substances such as tiny suspended matter, colloidal particles, organic matter, residual chlorine, odor and some heavy metal ions;

[0061] Finally, the water treated by the activated carbon filter cartridge 25 is guided to the ultrafiltration membrane cartridge 26 through the second water conduit 35; in the ultrafiltration membrane cartridge 26, the high-precision ultrafiltration membrane element intercepts and removes microscopic impurities such as bacteria, viruses, colloidal particles and most soluble solids in the water, producing high-quality purified water; the purified water is discharged through the outlet pipe 27 connected to the outlet of the ultrafiltration membrane cartridge 26 for subsequent use or discharge;

[0062] In addition, once harmful gases, odors and other pollutants are generated in the treatment pool 2, these pollutants will be immediately captured and collected by the adsorption cover 30. Subsequently, the fan 31 is activated, and its strong suction force causes the polluted air in the adsorption cover 30 to be quickly sucked in and transported to the purification box 32; the activated carbon filter 33 arranged in the purification box 32 can efficiently absorb harmful substances and odors in the air to keep the treatment environment clean.
