Description

Technical Field

[0001] The invention belongs to the technical field of reclaimed water reuse, and in particular relates to a reclaimed water reuse device and a reclaimed water reuse method. Background Art

[0002] With the acceleration of industrialization and urbanization, water shortage and pollution are becoming increasingly serious, becoming one of the key factors restricting the sustainable development of society. Traditional water resource management methods can no longer meet the growing water demand, especially in areas with scarce water resources. Finding new water resource channels and realizing efficient recycling of water resources has become a top priority.

[0003] Under this background, the technology of reclaimed water reuse has emerged as an important means to ease the shortage of water resources and reduce environmental pollution. Reclaimed water refers to domestic sewage and industrial wastewater that have been properly treated. Its water quality is between that of tap water and sewage, and is suitable for non-drinking water, such as agricultural irrigation, urban greening, industrial cooling, etc. Reclaimed water can effectively reduce the amount of fresh water used and the amount of sewage discharged, thus realizing the recycling of water resources and the dual protection of the ecological environment.

[0004] However, there are the following problems in traditional water reuse treatment:

[0005] Low treatment efficiency: Traditional water reuse systems often use relatively simple or outdated treatment processes. These methods are incapable of treating complex water quality, resulting in low treatment efficiency and affecting the quality of recycled water;

[0006] Direct emissions from water treatment affect air quality: During the treatment process, especially during biological treatment or aeration, a large amount of gas containing suspended matter, odor and volatile organic compounds will be generated; if these gases are directly discharged into the atmosphere without proper treatment, it will not only deteriorate the air quality, but also threaten the health of surrounding residents;

[0007] Single treatment mode cannot guarantee stable water quality: Traditional water reuse technology often relies on a single treatment mode, lacking flexibility and adaptability. Faced with water from different sources and with different pollution levels, a single treatment mode cannot guarantee the stability and compliance rate of water quality, and cannot meet the diverse and high-standard water quality needs.

[0008] Unstable water quality: Due to the limitations of the treatment process and the fluctuation of raw water quality, the water quality treated by the traditional reclaimed water reuse system is often very unstable; this instability not only affects the application scope and use effect of the recycled water, but may also have an adverse impact on subsequent treatment facilities. Summary of the invention

[0019] The present invention also provides a method for reclaiming reclaimed water, comprising the following method:

[0020] 1. Physical interception and sedimentation method: In the pretreatment tank, large solid particles and impurities are intercepted by a ring-shaped mesh pretreatment cylinder, and the suspended matter is deposited on the bottom of the tank by the natural flow of water, and then the impurities are discharged by the sewage pump with the assistance of the slag discharge pipe; this step is the preliminary stage of return water treatment, and large particle impurities are removed by physical means, providing a basis for subsequent treatment;

[0021] 2. Chemical flocculation and sedimentation method: Add flocculants into the regulating tank, stir the agitator shaft and scraper to fully mix the flocculants with water, and promote the coagulation and precipitation of suspended matter; this step uses chemical methods to accelerate the removal of suspended matter, improve water quality, and prepare for subsequent deep purification;

[0022] 3. Deep filtration and adsorption method: A stainless steel filter layer and an activated carbon filter layer are set in the fine filter box to remove tiny particles, suspended matter and some bacteria, and adsorb harmful substances such as organic matter, residual chlorine, odor, pigments, etc. This step deeply purifies the water quality through fine filtration and adsorption, so that the water reaches a higher reuse standard;

[0023] 4. Multi-stage filtration and membrane treatment: After the water passes through the fine filter box, it is sequentially filtered through filter tanks equipped with fiber ball filter media, quartz sand filter media and reverse osmosis membrane filter media for multi-stage filtration treatment; this step utilizes the synergistic effect of multi-stage filtration and membrane technology to further deeply purify the water quality and ensure that the recycled water meets higher water quality standards.

[0024] Compared with the prior art, the embodiments of the present application have the following beneficial effects:

[0025] First, the pretreatment component of the present invention effectively blocks and removes large particles of impurities and suspended matter in the raw water, and at the same time uses a sewage pipe and a sewage pump to automatically discharge sludge impurities at the bottom of the pool, thereby maintaining the cleanliness and efficient operation of the pretreatment pool and laying a solid foundation for subsequent treatment steps; a stirring system is integrated in the regulating pool, and the rotation of the stirring shaft drives the scraper to stir the water body, which not only accelerates the mixing reaction between the raw water and the flocculant, but also promotes the rapid coagulation and precipitation of suspended matter in the water, significantly improving the uniformity and clarity of the water quality, and creating favorable conditions for subsequent deep purification; the ultraviolet sterilization lamp equipped in the regulating pool can efficiently and quickly kill bacteria, viruses and other microorganisms in the water, ensuring that the water quality meets safety standards, providing reliable guarantees for the widespread use of recycled water, and meeting the high standards for water quality in different fields.

[0026] Secondly, the gas and water containing suspended matter generated during the stirring process of the present invention are guided to the washing area of ​​the box, and this area creates strong water flow disturbance through the rotation of the rotating blades; this disturbance enables sufficient and effective contact between the gas and the washing water, thereby performing preliminary washing and purification treatment; this design not only effectively removes suspended matter and other impurities entrained in the gas, but also avoids the direct discharge of untreated gas into the air, causing potential pollution to the environment.

[0027] Thirdly, the water carefully treated in the regulating tank of the present invention then flows into the fine filter box and the multi-stage filter tank system in series. In this process, the water first passes through the stainless steel filter layer to effectively intercept and remove tiny particles and suspended matter in the water. Then, the water enters the activated carbon filter layer to deeply remove harmful substances such as organic matter, residual chlorine, odor and pigment in the water by using the powerful adsorption capacity of activated carbon. Then, the water passes through the filter tank equipped with fiber ball filter material, quartz sand filter material and reverse osmosis membrane filter material in turn. These filter materials work together to further remove residual bacteria, tiny impurities and soluble solids, thereby achieving deep purification of water quality. BRIEF DESCRIPTION OF THE DRAWINGS

[0039] It should be noted that due to the low treatment efficiency of traditional water reuse technology, it is difficult to effectively remove organic matter, nitrogen, phosphorus and other pollutants in complex water, which affects the quality of recycled water; if the gas generated during the treatment process is directly discharged without proper treatment, it will deteriorate the air quality and threaten the health of residents; relying on a single treatment mode, lacking flexibility and adaptability, it is difficult to ensure the stability of water quality of water from different sources and with different pollution levels. This solution ensures the purity, safety and sustainable use of water resources; specifically, through the fine filtration and automatic sewage discharge of the pretreatment component, the accelerated stirring and ultraviolet sterilization in the regulating tank 7, and the deep purification of the fine filter box 16 and the multi-stage filter tank 21, the present invention can remove all kinds of impurities, suspended matter, bacteria, viruses and organic matter in the raw water in an all-round and multi-level manner, and improve the water quality to a level far exceeding conventional standards; this process not only ensures the safety and reliability of recycled water, meets the high standards for water quality in various non-drinking water fields, but also realizes the maximum utilization and circulation of water resources, making important contributions to environmental protection and sustainable development.

[0040] Specifically, in this embodiment, the scheme mainly includes a pretreatment component and a fine filtration component; the raw water first enters the pretreatment tank 1 through the raw water pipe 2; in the pretreatment tank 1, a pretreatment cylinder 5 is provided, and its side wall is designed to be annular mesh-shaped, such a design allows the water flow to pass smoothly, while effectively blocking larger solid particles and impurities; with the natural sinking of the water flow, the larger suspended matter and impurities in the pretreatment tank 1 are trapped in the pretreatment cylinder 5 or gradually deposited on the bottom of the tank; in order to keep the pretreatment tank 1 clean, the impurities deposited on the bottom of the tank are discharged through the slag discharge pipe 3, and this process is assisted by the sewage pump 4 to accelerate, so as to ensure that the impurities can be cleaned in time;

[0041] The water after preliminary pretreatment then flows into the regulating tank 7 through the first water pipe 6; in order to further improve the water quality in the regulating tank 7, an appropriate amount of flocculant is added to the tank through the medicine feeding port; at the same time, a stirring shaft 8 and a stirring connecting rod 9 are provided in the regulating tank 7, and a scraper 10 is installed on the connecting rod; the rotation of the stirring shaft 8 and the stirring connecting rod 9 drives the scraper 10 to stir in the tank, so that the flocculant and water are fully mixed, and the coagulation and precipitation of suspended matter in the water are promoted; this stirring process not only helps to further even out the water quality, but also lays a good foundation for subsequent treatment steps;

[0042] During the stirring process, the water in the regulating tank 7 may generate a certain amount of gas; the gas is introduced into the box 11 through the second water pipe 12; in the box 11, the lower area is provided with a washing area, which is filled with washing water; when the gas and the water containing a small amount of suspended matter enter the washing area, the rotating rod 13 drives the rotating blade 14 to rotate, generating a strong water flow disturbance; this disturbance makes the gas fully contact with the washing water, and performs a preliminary washing and purification effect

[0043] The gas treated in the washing area continues to rise and enters the microporous filter membrane layer 15 on the upper part of the box 11; the microporous filter membrane layer 15, with its fine filtering pore size, can further filter out impurities such as tiny particles, suspended matter, bacteria, etc. in the gas, thereby significantly improving the gas emission standard.

[0044] In a further preferred embodiment of the present invention, Figure 1-6 As shown, the fine filter assembly includes: a fine filter box 16, which is arranged at a side of the regulating tank 7 away from the box body 11; a third water pipe 17 is connected between the lower position of the regulating tank 7 and the upper position of the fine filter box 16; a plurality of stainless steel filter layers 18 are arranged at the upper position of the inner cavity of the fine filter box 16; and a plurality of activated carbon filter layers 19 are arranged at the lower position of the inner cavity of the fine filter box 16.

[0045] In this embodiment, the water passing through the regulating tank 7 flows into the fine filter box 16 through the third water pipe 17; the fine filter box 16 is arranged on the side of the regulating tank 7 away from the box body 11 to ensure that the water flow can enter smoothly and receive further filtering treatment; in the fine filter box 16, the water flow first passes through a plurality of stainless steel filter layers 18 arranged at the upper position of the inner cavity; these stainless steel filter layers 18 have fine filtering pores, which can effectively intercept and remove impurities such as tiny particles, suspended matter and some bacteria in the water; the selection of stainless steel material ensures the durability and corrosion resistance of the filter layer, and can maintain a stable filtering effect in long-term use;

[0046] The water that has been initially filtered by the stainless steel filter layer 18 continues to flow downward to the activated carbon filter layer 19 at the lower part of the inner cavity of the fine filter box 16; the activated carbon filter layer 19 is known for its strong adsorption capacity, and can absorb harmful substances such as organic matter, residual chlorine, odor, pigments, etc. in the water to further purify the water quality.

[0047] In a further preferred embodiment of the present invention, Figure 1-7 As shown, the fine filter assembly also includes: a mounting bracket 20, which is arranged on a side of the fine filter box 16 away from the regulating tank 7; three filter tanks 21 are arranged on the mounting bracket 20, and the top and bottom positions of the three filter tanks 21 are respectively provided with water inlets 22 and drain outlets 23 connected to their inner cavities; the water inlets 22 and drain outlets 23 of the three filter tanks 21 are connected in series and communicated in sequence through a fourth water pipe 24, and one end of the fourth water pipe 24 is connected to the fine filter box 16.

[0048] In this embodiment, after the fine filter box 16 completes the preliminary deep purification, the water flows out through the fourth water conduit 24 and is connected to the water inlet 22 of the first filter tank 21 on the mounting bracket 20; the mounting bracket 20 is firmly arranged on the side of the fine filter box 16 away from the regulating tank 7, ensuring that the filter tank 21 can stably receive and process the water flow from the fine filter box 16;

[0049] Different types of filter media are installed inside the three filter tanks 21, and the design of the fourth water pipe 24 ensures that the water flow can be connected in series and connected to the three filter tanks 21 in sequence, thereby realizing continuous multi-stage filtration.

[0050] In a further preferred embodiment of the present invention, Figure 1 As shown, the filter tank 21 is filled with fiber ball filter material, quartz sand filter material and reverse osmosis membrane filter material in sequence.

[0051] In this embodiment, when the filter tank 21 is filled with fiber ball filter material, quartz sand filter material and reverse osmosis membrane filter material in sequence, these filter material layers achieve multi-stage and deep purification of water through their respective filtration mechanisms and synergistic effects. Ultimately, the water quality of the water treated by the filter tank 21 is greatly improved and reaches a higher reuse standard.

[0052] In a further preferred embodiment of the present invention, Figure 4 As shown, a first motor 25 is disposed at the bottom of the box body 11 , and an output end of the first motor 25 is fixedly connected to an end key of the rotating rod 13 .

[0053] In this embodiment, after receiving the power provided by the first motor 25, the rotating rod 13 starts to rotate, and the rotation speed, direction and stability of the rotating rod 13 are precisely controlled by the first motor 25, thereby ensuring the smooth progress of the washing and purification process inside the box 11.

[0054] In a further preferred embodiment of the present invention, Figure 3 As shown, a second motor 26 is disposed at the bottom of the regulating tank 7 , and an output end of the second motor 26 is fixedly connected to an end part of the stirring shaft 8 .

[0055] In this embodiment, after receiving the power provided by the second motor 26, the stirring shaft 8 starts to rotate. The rotation of the stirring shaft 8 promotes the flow and mixing of water in the regulating tank 7, and helps to evenly distribute suspended matter, flocculants, etc. in the water throughout the tank body. This homogenization process is crucial to improving the effectiveness of subsequent treatment steps and ensuring the consistency and stability of water quality.

[0056] In a further preferred embodiment of the present invention, Figure 3 As shown, an ultraviolet sterilization lamp 27 is arranged on the side wall of the inner cavity of the regulating tank 7.

[0057] In this embodiment, when the ultraviolet sterilization lamp 27 irradiates the water in the regulating tank 7, it can quickly kill bacteria, viruses and other microorganisms in the water. At the same time, since ultraviolet rays have strong penetrability and can penetrate deep into the water, they can also have a good killing effect on microorganisms hidden in the water. By setting the ultraviolet sterilization lamp 27 in the regulating tank 7, the safety of water quality can be significantly improved. In the water body after sterilization, the number of microorganisms is greatly reduced, reducing the risk of water pollution, and providing a safer and more reliable water source for subsequent processing steps.

[0058] In a further preferred embodiment of the present invention, Figure 1-7 As shown, the second water conduit 12 is provided with a first pump body 28 , the third water conduit 17 is provided with a second pump body 29 , and the fourth water conduit 24 is provided with a third pump body 30 .

[0059] In this embodiment, the first pump body 28, the second pump body 29 and the third pump body 30 respectively arranged on the second water pipe 12, the third water pipe 17 and the fourth water pipe 24 play a key role in power transmission and water flow control in the entire water treatment system; they ensure that the water can flow through each treatment unit smoothly and efficiently, thereby achieving gradual purification and improvement of water quality; at the same time, the setting of these pump bodies also increases the flexibility and controllability of the system, so that the operator can flexibly adjust and optimize the treatment effect according to actual conditions.

[0060] In a further preferred embodiment of the present invention, Figure 1-7 As shown, a medicine feeding port communicating with the inner cavity of the regulating tank 7 is provided at the top thereof, and a sealing cover 31 is hingedly connected to the medicine feeding port.

[0061] In this embodiment, the medicine feeding port serves as an interface between the regulating tank 7 and the external environment, allowing the operator to feed the required chemical agents or other treatment agents into the regulating tank 7 through this port to improve water quality, promote coagulation and precipitation of suspended matter, kill microorganisms, etc. The sealing cover 31 is designed to tightly seal the medicine feeding port when no agent needs to be added, preventing external impurities, dust or rainwater from entering the regulating tank 7, thereby maintaining the cleanliness and stability of the water quality.

[0062] Working principle: When the present invention is used, raw water is first introduced into the pretreatment tank 1 through the raw water pipe 2; in the pretreatment tank 1, a pretreatment cylinder 5 with an annular mesh shape is designed, and its side wall allows water to flow smoothly, while effectively blocking larger solid particles and impurities; with the natural flow of water, larger suspended matter and impurities in the pretreatment tank 1 are trapped in the pretreatment cylinder 5 or gradually deposited on the bottom of the tank; in order to keep the pretreatment tank 1 clean, the impurities deposited on the bottom of the tank are discharged through the slag discharge pipe 3, and this process is accelerated by the sewage pump 4 to ensure that the impurities can be cleaned in time;

[0063] The water after preliminary pretreatment then flows into the regulating tank 7 through the first water pipe 6; in order to improve the water quality in the regulating tank 7, an appropriate amount of flocculant is added to the tank through the medicine feeding port; the regulating tank 7 is also provided with a stirring shaft 8 and a stirring connecting rod 9, and a scraper 10 is installed on the connecting rod; when the stirring shaft 8 rotates, it drives the stirring connecting rod 9 and the scraper 10 to stir in the tank, so that the flocculant and water are fully mixed, and the coagulation and precipitation of suspended matter in the water are promoted; this stirring process not only helps to uniform the water quality, but also lays a good foundation for subsequent treatment steps; at the same time, an ultraviolet sterilization lamp 27 is provided in the regulating tank 7 to irradiate the water body, quickly kill bacteria, viruses and other microorganisms in the water, and ensure the safety of water quality;

[0064] The gas and water containing a small amount of suspended matter generated during the stirring process are introduced into the box 11 through the second water pipe 12; a washing area is provided in the lower area of ​​the box 11. When the gas and water enter the washing area, the rotating rod 13 drives the rotating blade 14 to rotate, generating a strong water flow disturbance, so that the gas is fully in contact with the washing water for preliminary washing and purification; the gas treated in the washing area continues to rise and enters the microporous filter membrane layer 15 at the upper part of the box 11 for further filtration to remove impurities such as tiny particles, suspended matter, and bacteria;

[0065] The water treated in the regulating tank 7 flows into the fine filter box 16 through the third water pipe 17; the fine filter box 16 is provided with a stainless steel filter layer 18 and an activated carbon filter layer 19, which are respectively used to remove tiny particles, suspended matter and some bacteria in the water, and adsorb harmful substances such as organic matter, residual chlorine, odor, pigments, etc.; after deep purification in the fine filter box 16, the water flows out through the fourth water pipe 24, and sequentially passes through the three filter tanks 21 on the mounting bracket 20 in series for multi-stage filtration treatment; these filter tanks 21 are filled with fiber ball filter material, quartz sand filter material and reverse osmosis membrane filter material, and through synergistic effect, the deep purification of water is achieved, and finally a higher reuse standard is achieved;

[0066] In the entire system, the first motor 25 drives the rotating rod 13 to rotate, ensuring the smooth progress of the washing and purification process inside the box 11; the second motor 26 drives the stirring shaft 8 to rotate, promoting the mixing of water and the coagulation of suspended matter in the regulating tank 7; and the pump body on each water pipe is responsible for providing power to ensure that the water flow can flow smoothly and efficiently through each treatment unit; the design of the medicine feeding port and the sealing cover 31 ensures that the regulating tank 7 can be conveniently added with medicine when needed, and kept clean and sealed when not needed.
