Description

Technical Field

[0001] This utility model relates to the field of wastewater recycling technology, and more specifically, to a wastewater recycling mechanism and a water treatment system. Background Technology

[0002] Currently, in the field of water treatment technology, ultrafiltration and reverse osmosis systems are widely used in processes such as demineralized water preparation and wastewater treatment. Both ultrafiltration and reverse osmosis require regular flushing in both processes. Without flushing, the equipment will quickly become clogged and scaled, leading to inoperability and even permanent damage to the filter membrane. In particular, reverse osmosis generates 25% concentrated wastewater during operation, which is usually discharged into the sewer system, resulting in significant waste.

[0003] In current technologies, the recovery of wastewater from ultrafiltration and reverse osmosis involves recycling reverse osmosis concentrate into the circulating water system via direct pipeline connection for reuse. While ultrafiltration backwash water and reverse osmosis concentrate can be used as makeup water in the circulating water system, the high concentration ratio of this water is not considered, thus increasing the concentration ratio of the circulating water. This leads to poor safety, making equipment using circulating water more prone to scaling and corrosion, increasing operational safety risks. Utility Model Content

Detailed Implementation

[0021] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0022] Please refer to Figure 1 and Figure 2 This application provides a wastewater recycling mechanism, including: a first recycling component 100, which includes a cleaning tank 110 and a first filter component 120. The cleaning tank 110 is used to clean an ultrafiltration unit. The cleaning tank 110 is connected to the inlet end of the first filter component 120, and the outlet end of the first filter component 120 is connected to the inlet end of the cleaning tank 110. The cleaning liquid in the cleaning tank 110 is filtered by the first filter component 120 and then returned to the cleaning tank 110. The second recycling component 200 includes a reverse osmosis water treatment component 210, a first reverse osmosis tank 220, and a second filter component 230. The outlet end of the first reverse osmosis tank 220 is connected to the reverse osmosis water treatment component 210 and the second filter component 230, respectively. The outlet end of the second filter component 230 is connected to the reverse osmosis water treatment component 210.

[0023] The wastewater recycling mechanism provided in this application includes a first recycling component 100 and a second recycling component 200. The first recycling component 100 is used to treat ultrafiltration backwash water, and the second recycling component 200 is used to treat reverse osmosis water. The first recycling component 100 includes a cleaning tank 110 and a first filter component 120. The cleaning tank 110 is used to clean the ultrafiltration unit. The cleaning tank 110 is connected to the inlet end of the first filter component 120, and the outlet end of the first filter component 120 is connected to the inlet end of the cleaning tank 110. The cleaning liquid in the cleaning tank 110 is filtered by the first filter component 120 and then returned to the cleaning tank 110. The second recycling component 200 includes a reverse osmosis water treatment component 210, a first reverse osmosis tank 220, and a second filter component 230. The outlet end of the first reverse osmosis tank 220 is connected to the reverse osmosis water treatment component 210 and the second filter component 230, respectively. The outlet end of the second filter component 230 is connected to the reverse osmosis water treatment component 210. The first recovery component 100, through the recycling of the cleaning tank 110 and the first filter component 120, can effectively recover wastewater generated during the ultrafiltration cleaning process. The second recovery component 200 further treats and recovers the concentrate from the reverse osmosis system, avoiding water waste and achieving efficient water resource recycling. Filtration and cleaning reduce the pollution caused by direct wastewater discharge, especially the second filter component 230, which filters out high concentrations of minerals and chemicals in the reverse osmosis concentrate, reducing potential pollution to natural water bodies. Wastewater recycling reduces the use of new water sources, thereby lowering overall operating costs. Simultaneously, the use of the first filter component 120 and the second filter component 230 avoids frequent replacement of expensive filter media, further reducing maintenance costs. By using the first filter component 120 and the second filter component 230 to deeply treat the recovered wastewater, suspended solids, impurities, and microorganisms can be removed, improving the quality of the recovered water, reducing the burden on subsequent equipment, and enhancing the stability and safety of the entire water treatment system. Regular cleaning and maintenance of ultrafiltration and reverse osmosis systems can effectively prevent clogging and scaling inside the equipment, extend the service life of the equipment, and reduce the frequency of equipment replacement and maintenance.

[0024] Specifically, the first recycling component 100 further includes: a first pipeline 130, with its two ends connected to the outlet of the cleaning tank 110 and the inlet of the first filter element 120, respectively; and a second pipeline 140, with its two ends connected to the outlet of the first filter element 120 and the inlet of the cleaning tank 110, respectively. The combined use of the first pipeline 130 and the second pipeline 140 forms a closed-loop circulation system. This not only ensures the cleanliness of the cleaning solution during recycling but also avoids direct discharge of the cleaning solution, reducing environmental pollution. The cleaning solution in the cleaning tank 110 is transported to the first filter element 120 via the first pipeline 130, and then the filtered cleaning solution is returned to the cleaning tank 110 via the second pipeline 140, achieving the reuse of the cleaning solution, greatly saving water resources and reducing water treatment costs. The first filtration component 120 effectively removes suspended solids, impurities, and microorganisms from the cleaning solution, ensuring its quality and thus improving the cleaning efficiency of the ultrafilter, reducing the frequency of subsequent cleaning, and extending the ultrafilter's lifespan. The closed-loop circulation system simplifies the wastewater recycling process, reduces the workload of operators, minimizes operational errors, and improves the overall efficiency and stability of the water treatment system.

[0025] Among them, such as Figure 1 As shown, the first recovery component 100 further includes: a first water storage component 150, disposed on and connected to the first pipeline 130, through which the cleaning fluid in the cleaning tank 110 flows into the first filter component 120; and a first monitoring component, disposed within the first water storage component 150, which monitors the liquid level within the first water storage component 150. The first monitoring component can monitor the liquid level in the first water storage component 150 in real time, ensuring a stable supply of cleaning fluid and preventing pump idling due to low liquid level or overflow due to high liquid level, thus improving the stability and safety of the system. The first water storage component 150 acts as a buffer and regulator, effectively balancing the liquid flow between the cleaning tank 110 and the first filter component 120, making the cleaning fluid recovery and filtration process more stable and preventing a decrease in filtration effect due to unstable flow rate. As the cleaning solution flows from the first water storage component 150 to the first filter component 120, suspended solids are further precipitated and separated, reducing the filtration burden on the first filter component 120 and improving filtration efficiency and the quality of the recovered cleaning solution. The introduction of the first monitoring component enables automated control of the system. For example, by connecting a liquid level sensor to the controller, filtration automatically stops or cleaning solution replenishment begins when the liquid level is below a set value; conversely, discharge or recycling is automatically initiated when the liquid level is above a set value, achieving intelligent management of wastewater recovery.

[0026] In specific implementation, the first recycling component 100 further includes: a first pump body 160, disposed on and connected to the first pipeline 130, located between the first water storage component 150 and the first filter component 120; and a first control valve 170, disposed on and connected to the first pipeline 130, located between the first water storage component 150 and the first filter component 120, which regulates the flow rate within the first pipeline 130. The first pump body 160 provides power for wastewater circulation, ensuring that wastewater can be smoothly drawn from the cleaning tank 110, filtered through the first filter component 120, and then returned to the cleaning tank 110, thereby improving the circulation efficiency and speed of wastewater treatment. The first control valve 170, located between the first pump body 160 and the first filter component 120, can precisely regulate the flow rate of wastewater passing through the first filter component 120. This helps optimize the filtration process, ensuring that the first filter element 120 maintains optimal operating condition under different operating conditions, avoiding overload or inefficiency. Fine-grained flow management via the first control valve 170 avoids unnecessary wastewater circulation, reducing the operating time and energy consumption of the first pump body 160, thereby achieving energy conservation and consumption reduction. The stable power provided by the first pump body 160 and the flow regulation by the first control valve 170 reduce wear and damage to the first filter element 120, extending its service life, while also lowering the frequency and cost of equipment maintenance and replacement.

[0027] Furthermore, the first filtration component 120 includes a filter tank, the inlet of which is connected to the outlet of the cleaning chamber 110, and the outlet of which is connected to the inlet of the cleaning chamber 110. Activated carbon particles are installed inside the filter tank to filter the cleaning solution. Activated carbon has a strong adsorption capacity, effectively removing organic matter, residual chlorine, and other harmful substances from the cleaning solution, purifying it so that it can be reused for cleaning the ultrafilter, thus improving the reusability of the cleaning solution. Activated carbon can adsorb and filter suspended solids and impurities in the cleaning solution, reducing the NTU (turbidity unit) of the cleaning solution, ensuring its clarity, avoiding secondary pollution of the ultrafilter, and extending the service life of the ultrafilter. Filtration by activated carbon particles effectively reduces microorganisms and bacteria in the cleaning solution, lowering the risk of microbial contamination during system operation and ensuring the stable operation of the water treatment system. The circulation design between the filter tank and the cleaning chamber simplifies the wastewater recycling process, eliminating the need for additional treatment steps, reducing the workload of operators, and improving work efficiency.

[0028] The backwash water collection tank collects ultrafiltration backwash water. The water level is controlled by an automatic water level controller in the tank (first water storage component 150). When the water level reaches the preset high water level, the controller starts the water pump to transport the water in the tank to the activated carbon tank for filtration. When the water level is pumped to the preset low water level, the controller stops the water pump, and the tank enters the water storage state. This cycle repeats continuously.

[0029] like Figure 2 As shown, the second recovery component 200 further includes: a third pipe 240, the two ends of which are connected to the outlet of the first reverse osmosis tank 220 and the inlet of the second filter component 230, respectively; and a fourth pipe 250, the two ends of which are connected to the outlet of the second filter component 230 and the inlet of the first reverse osmosis tank 220, respectively. The third pipe 240 ensures that the effluent from the first reverse osmosis tank 220 flows smoothly into the second filter component 230 for deep filtration, while the fourth pipe 250 ensures that the filtered water can be directly returned to the first reverse osmosis tank 220, forming a closed-loop recovery system. This design not only improves the wastewater recovery rate but also ensures continuous improvement in water quality, guaranteeing the reuse value of the recovered water. Through the connection of the third pipe 240 and the fourth pipe 250, the second recovery component 200 can flexibly adjust the water flow path according to water quality and system requirements during operation, avoiding blockage or stagnation of water flow and enhancing the stability and operational flexibility of the system. This design reduces the need for fresh water and wastewater discharge, enabling effective recovery and reuse of concentrated water, which is beneficial for energy conservation, emission reduction, and environmental protection. By reducing environmental impact, it also lowers energy consumption and costs in the water treatment process. After being treated by the second filter element 230, impurities and harmful substances in the concentrated water are effectively removed, increasing its reuse value and allowing it to re-enter the reverse osmosis system for recycling, thus optimizing water resource utilization efficiency. The added third and fourth pipelines 240 and 250 further automate the concentrated water recovery and retreatment process, reducing the need for manual operation, simplifying the operation process, and improving the system's automation level and operational efficiency.

[0030] Furthermore, the second recovery component 200 also includes: a second water storage component 260, installed on and connected to the third pipeline 240, through which liquid in the first reverse osmosis tank 220 flows out to the second filtration component 230; and a second monitoring component, installed within the second water storage component 260, which monitors the liquid level within it. The second water storage component 260 provides a buffer zone during the reverse osmosis concentrate recovery process, storing a certain amount of concentrate to prevent treatment interruptions or direct discharge of concentrate due to a mismatch between the immediate concentrate production and subsequent treatment capacity. It ensures continuous water supply to the second filtration component 230, improving the stability and efficiency of the treatment system. The second monitoring component within the second water storage component 260 enables real-time monitoring and control of the water level, preventing overflow due to excessively high water levels or pump idling due to excessively low water levels. By monitoring the water level, subsequent treatment processes can be adjusted promptly, ensuring the safe operation of the entire system. By temporarily storing the concentrate in the second water storage component 260, water can be supplied as needed based on the operating status and treatment requirements of the second filter component 230, avoiding unnecessary pumping, reducing energy consumption, and improving the system's economy. The presence of the second water storage component 260 makes the recycling of reverse osmosis concentrate more flexible. When treatment demand is low, concentrate can be temporarily stored; when treatment demand is high, concentrate can be quickly supplied for treatment, meeting the needs of different operating conditions. By temporarily storing the concentrate in the second water storage component 260, the impact of concentrate directly entering the second filter component 230 can be reduced, thereby reducing equipment wear and extending the equipment's service life.

[0031] The second recovery assembly 200 further includes: a second pump body 270, disposed on and connected to the third pipeline 240, located between the second water storage component 260 and the second filter component 230; and a second control valve 280, disposed on and connected to the third pipeline 240, located between the second water storage component 260 and the second filter component 230, controlling the flow rate within the third pipeline 240. The second pump body 270 ensures that reverse osmosis concentrate can be stably and efficiently delivered from the second water storage component 260 to the second filter component 230, providing the necessary power for concentrate recovery and circulation, thus making the system operate more smoothly. The second control valve 280 can finely regulate the flow rate of concentrate passing through the second filter component 230, preventing excessive concentrate from impacting or clogging the filter component, ensuring filtration efficiency and system operational stability. By regulating the flow rate through the second control valve 280, unnecessary circulation can be avoided, reducing pump operating time and energy consumption, achieving the goal of energy saving and consumption reduction, and lowering the system's operating costs. The introduction of the second pump body 270 and the second control valve 280 makes the wastewater recycling process more automated, reduces the need for manual operation, and improves the safety and convenience of operation.

[0032] Furthermore, the second recovery component 200 also includes a second reverse osmosis tank 290, which is installed on and connected to the fourth pipeline 250. The liquid filtered by the second filter component 230 flows through the second reverse osmosis tank 290 and then into the reverse osmosis water treatment component 210. Although the liquid filtered by the second filter component 230 removes most impurities and suspended solids, it may still contain a certain concentration of dissolved substances. Through further treatment in the second reverse osmosis tank 290, these dissolved substances can be further removed, significantly improving water quality and bringing it closer to the raw water standard. This allows it to safely re-enter the reverse osmosis water treatment component 210 for further treatment, increasing the reuse value of the concentrate. In traditional reverse osmosis processes, a portion of the concentrate is directly discharged due to its high concentration of dissolved substances. However, the second reverse osmosis tank 290 in this solution can perform advanced treatment on this concentrate, enabling its recycling and reuse. This improves the overall wastewater recovery rate of the system, reduces wastewater discharge, and has positive implications for environmental protection. The advanced treatment by the second reverse osmosis tank 290 reduces the need for fresh water sources, lowers chemical consumption in wastewater treatment, reduces subsequent maintenance costs, and improves the overall system's economic efficiency. The second reverse osmosis tank 290 also serves as a stabilizing element in the second recovery component 200, preventing system fluctuations caused by direct return of concentrated water to the reverse osmosis water treatment component 210, thus ensuring the stable operation of the reverse osmosis system.

[0033] Fresh water from the reverse osmosis system enters the concentrate collection tank (second water storage component). A water pump then sends the water to the security filter (second filtration component). A flow meter is installed at the pump outlet valve. A recirculation valve and pipeline are installed before the pump outlet valve. After filtration by the security filter, the water enters the concentrate filtration reverse osmosis system. The permeate from the concentrate filtration reverse osmosis system then enters the RO water tank. The concentrate filtration reverse osmosis backwash pipeline is connected in parallel with the fresh water reverse osmosis backwash pipeline, and the backwash water uses water from the RO water tank. The system operates by collecting the concentrate in the collection tank. The water level is controlled by an automatic water level controller. When the water level reaches the preset high level, the controller starts the pump, sending water from the tank to the security filter and concentrate filtration reverse osmosis system for filtration. When the water level reaches the preset low level, the controller stops the pump and starts the concentrate filtration reverse osmosis flushing program to flush the reverse osmosis system. The tank then enters a water storage state, and this cycle repeats continuously.

[0034] The key component of ultrafiltration backwash water recovery is the activated carbon filter, which can remove colloids, rust, impurities, COD (chemical oxygen demand), and reduce the SID value (an indicator of the concentration of ionized ions in a solution) in the ultrafiltration backwash water.

[0035] The key step in reverse osmosis concentrate recovery is the concentrate reverse osmosis (second reverse osmosis tank), which mainly utilizes a Dow BW30-400i saline-alkali membrane to filter calcium and magnesium ions from the concentrate wastewater of the primary reverse osmosis of fresh water. In this scheme, the concentrate reverse osmosis can be replaced by a mixed bed, which also has the characteristics of filtering calcium, magnesium ions, and silica. The activated carbon filter can use low-quality activated carbon products (such as: briquetted carbon, carbonized carbon, and low-iodine carbon).

[0036] The backwash water for ultrafiltration can be treated by adding flocculants to the water tank to remove suspended solids and impurities. Low-quality activated carbon products (such as briquetted carbon, carbonized carbon, and low-iodine carbon) can be used instead of activated carbon in activated carbon filter tanks.

[0037] This utility model also provides a water treatment system, including a wastewater recycling mechanism, which is the wastewater recycling mechanism described in the above embodiment.

[0038] By collecting and treating ultrafiltration backwash water and reverse osmosis concentrate separately, the wastewater recycling method of this application achieves efficient utilization of wastewater generated during water treatment. After filtration through an activated carbon filter, the ultrafiltration backwash water is purified and can be directly returned to the inlet pipe of the ultrafiltration system for re-entry into the water treatment cycle. The reverse osmosis concentrate, after deep treatment by the second filtration component and the concentrate reverse osmosis device, not only removes most of the calcium, magnesium ions, and silica, but also significantly improves the water recovery rate. The product water enters the RO water tank (i.e., reverse osmosis water treatment component 210) and can be reused as a supplementary water source or used for other non-potable purposes, such as cooling water or cleaning water.

[0039] As can be seen from the above description, the embodiments of this utility model achieve the following technical effects:

[0040] The wastewater recycling mechanism provided in this application includes a first recycling component 100 and a second recycling component 200. The first recycling component 100 is used to treat ultrafiltration backwash water, and the second recycling component 200 is used to treat reverse osmosis water. The first recycling component 100 includes a cleaning tank 110 and a first filter component 120. The cleaning tank 110 is used to clean the ultrafiltration unit. The cleaning tank 110 is connected to the inlet end of the first filter component 120, and the outlet end of the first filter component 120 is connected to the inlet end of the cleaning tank 110. The cleaning liquid in the cleaning tank 110 is filtered by the first filter component 120 and then returned to the cleaning tank 110. The second recycling component 200 includes a reverse osmosis water treatment component 210, a first reverse osmosis tank 220, and a second filter component 230. The outlet end of the first reverse osmosis tank 220 is connected to the reverse osmosis water treatment component 210 and the second filter component 230, respectively. The outlet end of the second filter component 230 is connected to the reverse osmosis water treatment component 210. The first recovery component 100, through the recycling of the cleaning tank 110 and the first filter component 120, can effectively recover wastewater generated during the ultrafiltration cleaning process. The second recovery component 200 further treats and recovers the concentrate from the reverse osmosis system, avoiding water waste and achieving efficient water resource recycling. Filtration and cleaning reduce the pollution caused by direct wastewater discharge, especially the second filter component 230, which filters out high concentrations of minerals and chemicals in the reverse osmosis concentrate, reducing potential pollution to natural water bodies. Wastewater recycling reduces the use of new water sources, thereby lowering overall operating costs. Simultaneously, the use of the first filter component 120 and the second filter component 230 avoids frequent replacement of expensive filter media, further reducing maintenance costs. By using the first filter component 120 and the second filter component 230 to deeply treat the recovered wastewater, suspended solids, impurities, and microorganisms can be removed, improving the quality of the recovered water, reducing the burden on subsequent equipment, and enhancing the stability and safety of the entire water treatment system.
