[0002] Water treatment is a key field related to ecological balance and human health. It encompasses a series of complex processes from water source protection to sewage purification and then to the rational allocation and utilization of water resources. At the water source, measures such as vegetation conservation and water quality monitoring are taken to ensure the excellent quality of raw water and prevent the intrusion of pollutants. For various types of sewage, whether it is domestic sewage, industrial water sources, or agricultural non-point source polluted water, targeted treatment processes are required. For example, domestic sewage often uses biological treatment methods, with the help of microorganisms to decompose organic pollutants; industrial water sources, depending on the heavy metals and chemical substances they contain, comprehensively use technologies such as chemical precipitation, ion exchange, and membrane separation to remove harmful substances and make them meet the discharge standards or be reusable. Reasonable water treatment can not only effectively prevent and control water pollution, protect the diversity and stability of the water ecosystem, but also alleviate the severe situation of water resource shortage, provide a solid water resource guarantee for the sustainable development of social economy, and is an important cornerstone for achieving harmonious coexistence between humans and nature.

[0004] The above system for the integrated nanofiltration direct drinking water treatment process route of tap water does not have steps for treating heavy metals. Heavy metals cannot be removed through ordinary filtration, resulting in a certain amount of heavy metals remaining in the filtered water source. Long-term drinking of water containing heavy metals will seriously endanger human health. Summary of the Invention

Detailed implementation manners

[0036] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0037] Embodiment 1: Please refer to Figure 1 , the present invention provides a technical solution: an integrated water treatment system for tap water, including steps:

[0038] S1: Introduce the water source into the sedimentation tank 2, and start the transducer assembly 8 installed in the sedimentation tank 2. The ultrasonic transducer 82 is installed on the wall scraper 74 and is arranged in a circumferential shape around the sedimentation tank 2 to form a multi-dimensional ultrasonic field. Its operating frequency range is set at 20 - 50 kHz, and the power can be adjusted between 500 - 2000 W. By precisely controlling the frequency and power of the ultrasonic wave, ultrasonic waves with different intensities and frequencies can be generated to meet the treatment requirements of heavy metal water sources with different properties and concentrations. For water sources with higher concentrations and lower reaction activities between metal ions and precipitants, the ultrasonic power can be appropriately increased to enhance the cavitation effect and promote the precipitation reaction. The ultrasonic transducer 82 is encapsulated with waterproof and corrosion-resistant materials to ensure long-term stable operation in the water source environment. At the same time, a cooling system is equipped to prevent the ultrasonic transducer 82 from being affected in performance or damaged due to heat generation during long-term operation. Then, add a precipitant. The precipitant sodium sulfide is added to the sedimentation tank 2 through a precision metering pump according to the set flow rate and concentration. Under the action of ultrasonic waves, sodium sulfide quickly disperses and is evenly mixed with the heavy metal ions in the water source, making it mix with the water source. The addition amount of the precipitant is pre-calculated according to the initial heavy metal ion concentration and type of the water source, and can be adjusted in real time according to the feedback of the precipitation monitoring device during the treatment process. For mercury-containing water sources, the addition amount of sodium sulfide needs to be precisely controlled to ensure that mercury ions are completely precipitated to form mercury sulfide precipitation, while avoiding secondary pollution caused by excessive sodium sulfide;

[0039] S2: The metal ion concentration detector detects the water source. The precipitation monitoring device uses an online heavy metal ion concentration detector to continuously monitor the heavy metal ion concentration in the supernatant of the sedimentation tank. The detector adopts the principle of advanced inductively coupled plasma optical emission spectrometry (ICP - OES) or atomic absorption spectrometry (AAS), and has the characteristics of high precision and high sensitivity, and can quickly and accurately detect the concentrations of various heavy metal ions, such as lead, cadmium, chromium, nickel, etc., and transmit the data to the central control system.

[0040] The central control system is built-in with advanced data analysis algorithms and models to conduct real-time analysis and processing of the collected data. By establishing kinetic models for heavy metal ion removal, resin adsorption isotherm models, photocatalytic oxidation reaction kinetic models, etc., it predicts the treatment effects and operating states of each unit. According to the flow rate in the front section of the adsorption tower, the resin adsorption capacity, and the heavy metal ion concentration in the influent water, it predicts the adsorption situation of the resin in the rear section and the overall treatment effect of the adsorption tower; according to the light intensity, reaction temperature, and pH value of the photocatalytic oxidation unit, it predicts the generation amount of hydroxyl radicals and the oxidation rate of heavy metal ions. Based on the data analysis results, the central control system automatically generates an optimized operation plan and determines the optimal operating parameters for each unit. For example, it adjusts the ultrasonic power, precipitant addition amount, and stirring speed of the ultrasonic-assisted precipitation tank; controls the flow rate of each section of the ion exchange resin adsorption tower, the resin regeneration timing, and the regenerant dosage; regulates the light intensity, reaction temperature, pH value, and catalyst cleaning cycle of the photocatalytic oxidation unit, etc. The central control system has remote monitoring and operation functions. Operators can remotely log in to the central control system through the Internet or the enterprise internal network using terminal devices such as computers, mobile phones, or tablets to view the operation data and status of each unit in real time, as well as the treatment effect of the entire system. When working outside the office or in case of an emergency, operators can remotely monitor the operation of the system through mobile phones, promptly discover problems and handle them.

[0041] When it is monitored that the heavy metal ion concentration in the supernatant exceeds the set threshold, the central control system automatically adjusts the ultrasonic power and precipitant addition amount. If the lead ion concentration is too high, the central control system may increase the ultrasonic power by 10% and at the same time increase the addition amount of sodium sulfide by 5% to promote the precipitation reaction of lead ions until the lead ion concentration in the supernatant reaches the standard;

[0042] S3: The water source is introduced into the ion exchange resin adsorption tower. The adsorption tower adopts a segmented filling method. According to the differences in the adsorption kinetics and adsorption capacity of different heavy metal ions, the resin is divided into several segments for filling. For copper ions with a relatively fast adsorption rate but a relatively small adsorption capacity, the resin with better copper ion adsorption effect can be filled in the front section of the adsorption tower; while for cadmium ions with a slower adsorption rate but a larger adsorption capacity, the corresponding resin is filled in the rear section of the adsorption tower. The filling height and volume of each segment of resin are precisely designed according to the flow rate of the water source, the composition of heavy metal ions, and the treatment requirements. Each segment of the adsorption tower is equipped with an independent flow rate control system, and precise flow rate adjustment is achieved through a regulating valve and a flow meter. The control range of the flow rate is between 5 - 30 m³ / h, and it can be dynamically adjusted according to the adsorption characteristics of different segments of resin and the treatment requirements. In the front section of the adsorption tower, when treating a water source with a relatively high copper ion concentration, the flow rate can be appropriately reduced to extend the contact time between the water source and the resin, thereby increasing the adsorption rate of copper ions; while in the rear section of the adsorption tower, for cadmium ions with a slower adsorption rate, the flow rate can be gradually reduced according to the adsorption situation of cadmium ions to ensure the full adsorption of cadmium ions. A pressure monitoring device is installed inside the adsorption tower to monitor the pressure changes in each segment in real time. When the pressure exceeds the set value, the central control system will automatically adjust the flow rate or start the backwashing procedure to prevent the resin from being compacted or blocked due to excessive pressure, which may affect the adsorption effect. The resin regeneration system adopts an automated design. When the resin adsorption reaches saturation, it automatically switches to the regeneration process. The regenerant is a hydrochloric acid or sulfuric acid solution with a concentration of 2% - 5%. The regenerant is injected into the adsorption tower at a certain flow rate and pressure through a regeneration pump, so that the heavy metal ions adsorbed on the resin are eluted. The dosage and regeneration time of the regenerant are precisely calculated and controlled according to the saturation degree of the resin and the types of heavy metal ions adsorbed. For the heavy metal ions remaining in the water source after adsorption, the eluted regenerant solution contains high-concentration heavy metal ions, which are recovered and treated through a special recovery device. The recovery device uses methods such as ion exchange, electrodeposition, or chemical precipitation to separate heavy metal ions from the regenerant solution, obtaining high-purity heavy metal products and realizing the resource utilization of heavy metals. For example, for a copper-containing regenerant solution, the electrodeposition method can be used to deposit relatively pure copper metal on the cathode; for a cadmium-containing regenerant solution, the chemical precipitation method can be used by adding an appropriate precipitant to form a precipitate for cadmium ion recovery;

[0043] S4: Set prefabricated parameters for the photocatalytic unit. Introduce water source into the photocatalytic unit. The photocatalytic oxidation unit uses ultraviolet lamps as the light source, and its wavelength mainly concentrates between 254 - 365 nm. The power is adjusted between 100 - 1000 W according to the water treatment volume and the pollution degree of the water source. The light intensity adjustment device adopts an adjustable light shield or a power controller to accurately adjust the light intensity according to the instructions of the central control system. For example, when the content of organic pollutants in the treated water source is relatively high, appropriately increase the light intensity to increase the generation amount of active species such as hydroxyl radicals and accelerate the progress of the oxidation reaction. The residence time of the water source in the photocatalytic oxidation unit is controlled by the volume and flow rate of the reactor, generally between 30 - 120 minutes. The reaction temperature is controlled at 20 - 40 °C through a cooling or heating device to maintain the best activity of the photocatalytic reaction. At the same time, a pH adjustment device is provided in the reactor. According to the nature of the water source and the requirements of the photocatalytic reaction, the pH value is adjusted between 3 - 9 to optimize the photocatalytic oxidation effect, irradiate the water source, and decompose the residual trace heavy metal ions in the water source;

[0044] S5: Detect the secondary water source to check whether the water quality meets the standards.

[0045] Embodiment 2: Please refer to Figures 2 - 5 , the present invention provides a technical solution: An integrated water treatment system for tap water, including a protective shell 1 provided outside the sedimentation tank 2 in step S1. The protective shell 1 is used to protect the lifting structure 6 to prevent the lifting structure 6 from being damaged by external influences during operation. The protective shell 1 is arranged on the connecting frame 5. The connecting frame 5 is used to support the lifting structure 6, and the number of connecting frames 5 is two, divided into upper and lower layers, used to support the top and bottom ends of the lifting structure 6 to ensure that the lifting structure 6 can be stably kept upright. The connecting frame 5 is used to support the lifting structure 6.

[0046] The lifting structure 6 includes a threaded rod 61 and a limiting rod arranged on the connecting frame 5. The limiting rod penetrates through the connecting ring 63. Limiting plates are provided at the upper and lower ends of the threaded rod 61. A threaded sleeve 62 is arranged on the threaded rod 61. The limiting plates are used to limit the threaded sleeve 62 to prevent the threaded sleeve 62 from disengaging from the threaded rod 61 when moving on the threaded rod 61. A connecting ring 63 is arranged on the threaded sleeve 62. The connecting ring 63 is sleeved outside the threaded sleeve 62. The connecting ring 63 is used to connect with the outer connecting pipe 64. The outer connecting pipe 64 is connected to the connecting ring 63. The outer connecting pipe 64 is used to connect the lifting structure 6 and the connecting rope 7. The outer connecting pipe 64 is used to connect the connecting rope 7 and the connecting ring 63.

[0047] In this embodiment, the rotation of the threaded rod 61 can cause the threaded sleeve 62 thereon to rotate synchronously. However, due to the connection of the connecting rope 7 and the fixation of the limiting rod, it is ensured that the threaded sleeve 62 and the connecting ring 63 do not rotate along with the rotation of the threaded rod 61. Thus, the effect of moving up and down can be achieved by using the thread to drive the connecting rope 7 to move up and down.

[0048] Embodiment 3: Please refer to Figures 2 - 5 , the present invention provides a technical solution: an integrated water treatment system for tap water, including a connecting frame 5. The connecting frame 5 includes a rotating shaft 51 provided on a lifting structure 6. The rotating shaft 51 is used to drive the threaded rod 61 to rotate, ensuring that the threaded sleeve 62 thereon can move up and down. The number of lifting structures 6 is at least eight groups. A transmission gearbox 52 is connected to the rotating shaft 51. There are three helical gears in the transmission gearbox 52. Two of the three helical gears are respectively connected to both ends of a transmission rod 53, and the other is connected to one end of the rotating shaft 51, ensuring that the transmission rod 53 can drive the rotating shaft 51 to rotate through the helical gears, thereby driving the lifting structure 6 to operate. It can also continue to transmit power, so that the eight groups of lifting structures 6 can rotate synchronously. A transmission rod 53 is connected to the transmission gearbox 52. The transmission rod 53 is used to transmit the rotational power of the motor 4 to the rotating shaft 51 through the transmission gearbox 52, enabling the lifting structure 6 to rotate. The input end of the transmission rod 53 is connected to the motor 4.

[0049] In this embodiment, when the motor 4 is started, the motor 4 drives the transmission rod 53 to rotate. The transmission rod 53 drives eight rotating shafts 51 to rotate synchronously through the transmission gearbox 52. The rotating shaft 51 and the threaded rod 61 are fixedly connected by welding, so the lifting structure 6 can be driven to rotate synchronously.

[0050] Embodiment 4: Please refer to Figures 6 - 7, the present invention provides a technical solution: an integrated tap water treatment system, including a first collar 72 provided on a connecting rope 7, the first collar 72 is used to connect with a wall scraping device 74, and the wall scraping device 74 is used to scrape the inner wall of the sedimentation tank 2 to remove the impurities adhered to the sedimentation tank 2. The first collar 72 and the second collar 73 are sleeved together, and the second collar 73 is provided on the wall scraping device 74. A transducer assembly 8 is provided on the wall scraping device 74, which is used to perform ultrasonic treatment on the water source, so as to promote the contact between the precipitant and the water source. The transducer assembly 8 includes a control mechanism 81 and an ultrasonic transducer 82. The control mechanism 81 is used to control the transducer assembly 8. The wall scraping device 74 includes a wall scraping shovel 741 and a limiting ring 742. The wall scraping shovel 741 is used to scrape the inner side of the sedimentation tank 2, and the limiting ring 742 prevents the scraped impurities from floating upward. A downward-opening semi-circular shape is set to ensure that the impurities can be limited downward. The limiting ring 742 is provided on the wall scraping shovel 741. A support seat 71 is connected to the sedimentation tank 2, which is used to support the connecting rope 7. A roller is provided in the support seat 71 to support the connecting rope 7 and prevent the connecting rope 7 from rubbing against the top of the sedimentation tank 2. An outer discharge pipe 3 and inclined plates 21 are provided on the sedimentation tank 2. The inclined plates 21 facilitate the sinking and gathering of impurities, and are uniformly discharged outward through the outer discharge pipe 3.

[0051] In this embodiment, the lifting structure 6 drives the connecting rope 7 to move up and down. Thus, through the support of the support seat 71, the wall scraping device 74 is driven to move up and down inside the sedimentation tank 2. Since the transducer assembly 8 is provided on the wall scraping device 74, the center of gravity of the wall scraping device 74 changes. Due to the inclination, the wall scraping shovel 741 always adheres to the inner wall of the sedimentation tank 2 to scrape the sedimentation tank 2. The scraped particles are affected by the limiting ring 742 and slowly fall without floating upward. Finally, they fall onto the inclined plates 21 and are collected uniformly and discharged together through the outer discharge pipe 3.

[0052] Embodiment Five: The present invention provides a technical solution: an integrated tap water treatment system. Before step S1, the transducer assembly 8 is detected and the working frequency and power of the transducer assembly 8 are set according to the heavy metal concentration of the water source. Its working frequency range is set between 20 - 50 kHz, and the power can be adjusted between 500 - 2000 W. By precisely controlling the frequency and power of the ultrasound.

[0053] This embodiment can set the transducer assembly 8 in advance according to the water quality requirements, and can better generate ultrasonic waves with different intensities and frequencies to meet the treatment requirements of heavy metal water sources with different properties and concentrations. For water sources with higher concentrations and lower reaction activities of metal ions with precipitants, the ultrasonic power can be appropriately increased to enhance the cavitation effect and promote the precipitation reaction.

[0054] Embodiment Six: The present invention provides a technical solution: an integrated water treatment system for tap water. In step S3, the water source flows into the resin adsorption tower, and the flow rate of the water is controlled. Each section of the adsorption tower is equipped with an independent flow rate control system, and precise flow rate adjustment is achieved through a regulating valve and a flow meter. The control range of the flow rate is between 5 - 30 m³ / h, and it can be dynamically adjusted according to the adsorption characteristics and treatment requirements of different sections of the resin. For example, in the front section of the adsorption tower, when treating a water source with a relatively high copper ion concentration, the flow rate can be appropriately reduced to extend the contact time between the water source and the resin, thereby increasing the adsorption rate of copper ions; while in the rear section of the adsorption tower, for cadmium ions with a relatively slow adsorption rate, the flow rate can be gradually reduced according to the adsorption situation of cadmium ions to ensure the full adsorption of cadmium ions. Moreover, a pressure sensor and a backwashing program are provided on the resin adsorption tower. The pressure sensor transmits the pressure data received by the resin adsorption tower to the central control system, and the central control system controls the backwashing program, which is used to clean the resin adsorption tower.

[0055] In this embodiment, a pressure monitoring device is provided inside the adsorption tower to monitor the pressure changes in each section in real time. When the pressure exceeds the set value, the central control system will automatically adjust the flow rate or start the backwashing program to prevent the resin from being compacted or blocked due to excessive pressure, which may affect the adsorption effect.

[0056] Embodiment Seven: The present invention provides a technical solution: an integrated water treatment system for tap water. A detection system controlled by the central control system is provided on the resin adsorption tower to detect the adsorption degree of the resin adsorption tower. The precipitation monitoring device uses an on-line heavy metal ion concentration detector to monitor the heavy metal ion concentration in the supernatant of the sedimentation tank in real time. The detector adopts the principle of advanced inductively coupled plasma optical emission spectrometry (ICP-OES) or atomic absorption spectrometry (AAS).

[0057] This embodiment has the characteristics of high precision and high sensitivity, and can quickly and accurately detect the concentrations of various heavy metal ions, such as lead, cadmium, chromium, nickel, etc.
