Technical Field

[0001] The invention relates to the technical field of water treatment, in particular to an integrated tap water treatment system. Background Art

[0002] Water treatment is a key area related to ecological balance and human health. It covers a series of complex processes from water source protection to sewage purification to the rational allocation and utilization of water resources. At the water source, the excellent quality of raw water is ensured through vegetation conservation, water quality monitoring and other means to prevent the invasion of pollutants. For all kinds of sewage, whether it is domestic sewage, industrial water source or agricultural non-point source polluted water, targeted treatment processes are required. For example, domestic sewage is often treated by biological treatment, with the help of microorganisms to decompose organic pollutants; industrial water sources use chemical precipitation, ion exchange, membrane separation and other technologies according to the different heavy metals and chemicals they contain to remove harmful substances so that they meet the discharge standards or reuse standards. 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 shortage, provide a solid water resource guarantee for the sustainable development of social economy, and is an important cornerstone for the harmonious coexistence of man and nature.

Bottled water filling can be set according to the situation, and the bottled water can also be sold to nearby residents; multiple water supply schemes, cascade utilization of water sources, reduce water resource waste.

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

DETAILED DESCRIPTION

[0036] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0037] Embodiment 1

[0038] See also Figure 1 The present invention provides a technical solution: an integrated tap water treatment system, comprising the steps of:

[0039] S1: Introduce water source into sedimentation tank 2, start transducer assembly 8 in sedimentation tank 2, ultrasonic transducer 82 is arranged on scraper 74, and surrounds sedimentation tank 2 to form a multi-dimensional ultrasonic field, and its working frequency range is set at 20-50kHz, and the power can be adjusted between 500-2000W. By precisely controlling the frequency and power of ultrasound, ultrasonic waves of different intensities and frequencies can be generated to meet the treatment needs of heavy metal water sources of different properties and concentrations. For water sources with higher concentrations and lower reaction activity 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 that it is in the water source environment. The medium- and long-term stable operation is equipped with a cooling system to prevent the ultrasonic transducer 82 from being affected in performance or damaged due to heat during long-term operation. A precipitant is added. 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, the sodium sulfide is quickly dispersed and evenly mixed with the heavy metal ions in the water source to mix with the water source. The amount of precipitant added 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 amount of sodium sulfide added needs to be precisely controlled to ensure that the mercury ions are completely precipitated to form mercuric sulfide precipitation, while avoiding secondary pollution caused by excessive sodium sulfide;

[0040] S2: Metal ion concentration detector is used for water source detection. The sedimentation monitoring device adopts an online 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 advanced inductively coupled plasma emission spectrometry (ICP-OES) or atomic absorption spectrometry (AAS) principles, with the characteristics of high precision and high sensitivity. It can quickly and accurately detect the concentration of various heavy metal ions, such as lead, cadmium, chromium, nickel, etc., and transmit the data to the central control system.

[0041] The central control system has built-in advanced data analysis algorithms and models to analyze and process the collected data in real time. By establishing a heavy metal ion removal kinetic model, a resin adsorption isotherm model, a photocatalytic oxidation reaction kinetic model, etc., the treatment effect and operating status of each unit are predicted. According to the flow rate of the front section of the adsorption tower, the resin adsorption capacity and the heavy metal ion concentration in the influent, the adsorption of the resin in the back section and the overall treatment effect of the adsorption tower are predicted; according to the light intensity, reaction temperature and pH value of the photocatalytic oxidation unit, the amount of hydroxyl radicals produced and the oxidation rate of heavy metal ions are predicted. According to the data analysis results, the central control system automatically generates an optimized operation plan to determine the optimal operating parameters of each unit. Such as adjusting the ultrasonic power, precipitant addition and stirring speed of the ultrasonic assisted sedimentation tank; controlling the flow rate of each section of the ion exchange resin adsorption tower, the resin regeneration timing and the amount of regeneration agent used; adjusting the light intensity, reaction temperature, pH value and catalyst cleaning cycle of the photocatalytic oxidation unit. The central control system has remote monitoring and operation functions. Operators can use computers, mobile phones, tablets and other terminal devices through the Internet or the company's internal network to remotely log in to the central control system and view the operating data and status of each unit and the processing effect of the entire system in real time. When working away from home or in an emergency, operators can remotely monitor the operation of the system through their mobile phones, discover problems in a timely manner and deal with them.

[0042] When the concentration of heavy metal ions in the supernatant exceeds the set threshold, the central control system automatically adjusts the ultrasonic power and the amount of precipitant added. If the lead ion concentration is too high, the central control system may increase the ultrasonic power by 10% and increase the amount of sodium sulfide added by 5% to promote the precipitation reaction of lead ions until the lead ion concentration in the supernatant reaches the standard.

[0043] S3: The water source is introduced into the ion exchange resin adsorption tower. The adsorption tower adopts a segmented filling method. According to the adsorption kinetics and adsorption capacity differences of different heavy metal ions, the resin is divided into several sections for filling. For copper ions with a faster adsorption rate but a relatively small adsorption capacity, the resin with a better adsorption effect of copper ions can be filled in the front section of the adsorption tower; and for cadmium ions with a slower adsorption rate but a larger adsorption capacity, the corresponding resin is filled in the back section of the adsorption tower. The filling height and volume of each section of the resin are precisely designed according to the flow rate of the water source, the composition of heavy metal ions and the treatment requirements. Each section of the adsorption tower is equipped with an independent flow rate control system, which realizes precise flow rate adjustment through regulating valves and flow meters. The flow rate control range is 5-30m 3 / h, can be dynamically adjusted according to the adsorption characteristics and treatment requirements of different sections of resin. In the front section of the adsorption tower, when treating water sources with high copper ion concentration, the flow rate can be appropriately reduced to extend the contact time between the water source and the resin and improve the adsorption rate of copper ions; in the back section of the adsorption tower, for cadmium ions with a slower adsorption rate, the flow rate can be gradually reduced according to the adsorption of cadmium ions to ensure the full adsorption of cadmium ions. The adsorption tower is equipped with a pressure monitoring device to monitor the pressure changes of 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, affecting 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 regeneration agent uses a hydrochloric acid or sulfuric acid solution with a concentration of 2% to 5%. The regeneration agent is injected into the adsorption tower at a certain flow rate and pressure through the regeneration pump to elute the heavy metal ions adsorbed on the resin. The dosage of the regeneration agent and the regeneration time are accurately calculated and controlled according to the saturation degree of the resin and the types of heavy metal ions adsorbed. The residual heavy metal ions are adsorbed on the water source, and the eluted regeneration liquid contains high concentrations of heavy metal ions, which are recycled through a special recovery device. The recovery device uses ion exchange, electrodeposition or chemical precipitation to separate the heavy metal ions from the regeneration liquid to obtain high-purity heavy metal products and realize the resource utilization of heavy metals. For example, for copper-containing regeneration liquid, the electrodeposition method can be used to precipitate high-purity copper metal on the cathode; for cadmium-containing regeneration liquid, the chemical precipitation method can be used to add an appropriate amount of precipitant to precipitate the cadmium ions for recovery;

[0044] S4: Set prefabricated parameters for the photocatalytic unit, introduce the water source into the photocatalytic unit, and use ultraviolet lamps as light sources in the photocatalytic oxidation unit. The wavelength is mainly concentrated between 254-365nm, and the power is adjusted between 100-1000W according to the amount of water treated and the degree of pollution of the water source. The light intensity regulating device uses an adjustable sunshade or 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 high, the light intensity is appropriately increased to increase the production of active species such as hydroxyl free radicals and accelerate 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 by a cooling or heating device to maintain the optimal 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 needs 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 trace heavy metal ions remaining in the water source;

[0045] S5: Test the secondary water source to see if the water quality meets the standards.
