[0040] The following is a further detailed description of the specific implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0041] In the relevant technology, the main source of fluoride in the human body is drinking water. The body mechanism can absorb more than 80% of the soluble fluoride ions and fluorides, but excessive intake can cause dental and bone problems. At the same time, excessive fluoride concentration in water will also have a certain impact on the growth of aquatic organisms. Traditional water treatment technology cannot meet the treatment requirements of rural drinking water and cannot provide safe drinking water quality. The problem of fluoride pollution in drinking water in some rural areas of my country is particularly prominent and difficult to solve. The water quality problem has to be solved urgently. The available space is small, and an economical, highly automated, simple to operate and manage, and small-footprint rural drinking water treatment device is extremely needed. It is imperative to improve the drinking water environment of rural residents and ensure drinking water safety.

[0042] At present, the commonly used methods for defluoridation of water treatment include precipitation method, electrochemical method, adsorption method, ion exchange resin method, etc. Chemical precipitation method and coagulation precipitation method are the most commonly used methods in my country, but there are problems such as large amount of sludge and serious secondary pollution. Anion exchange resin has low selectivity for F-, and it is difficult to completely remove F- in water. It will also remove anions such as SO42-, NO3-, Cl- in water. The efficiency of defluoridation is very low, and almost all the minerals necessary for the human body in the water are removed. In addition, the cost of resin is also high, which greatly hinders its widespread application. Electrocoagulation is a new type of water treatment technology with many advantages such as high treatment efficiency, fast speed, simple operation, low amount of sludge, and no need to add chemical reagents. It has been applied in many water treatments. However, the high reaction energy consumption and the passivation problem of the anode limit the further development of electrocoagulation technology. Therefore, pulse technology is introduced into electrocoagulation to reduce process energy consumption. Therefore, this application designs a defluoridation device for rural drinking water based on pulse electrocoagulation to solve the problem of fluorine pollution in rural drinking water.

[0043] like Figure 1 As shown; an embodiment of the utility model provides a defluorination device for drinking water, and the defluorination device for drinking water comprises:

[0044] A reaction container 2, comprising a containing cavity and a water inlet end, wherein the containing cavity is communicated with the water inlet end, and the water inlet end is used for supplying drinking water to be treated into the containing cavity;

[0045] A reaction component is arranged in the accommodating chamber, and is used to perform an electric flocculation reaction on the drinking water to be treated in the accommodating chamber when power is supplied;

[0046] The ultrasonic reactor 7 is arranged in the accommodating cavity and connected to the reaction component, and is used for removing the flocculation on the reaction component through ultrasonic action.

[0047] The drinking water defluorination device of this embodiment can be applied to rural water purification equipment or filtering equipment, and can also be applied to municipal or household direct drinking water equipment.

[0048] The drinking water defluorination device of the present embodiment comprises a reaction container 2, a reaction component and an ultrasonic reactor 7. The drinking water to be treated is introduced into the containing chamber through the water inlet end. When the reaction component is energized, an electric flocculation reaction is performed on the drinking water to be treated in the containing chamber. During the reaction, floccules float to the water surface, and the treated drinking water is located below the floccules. The ultrasonic reactor 7 acts on the reaction component to cause the floccules on the reaction component to fall off, which can effectively clean the surface of the reaction component. By introducing the electric flocculation method, the process energy consumption is reduced. At the same time, the ultrasonic reactor 7 can effectively prevent the reaction component from being passivated and accelerate the reaction rate.

[0049] In this embodiment, the reaction container 2 can be a container that can be used for the electro-flocculation reaction, that is, it can be barrel-shaped or in other shapes, with a cavity inside it as a receiving chamber, and drinking water can be contained in the receiving chamber and an electro-flocculation reaction can be performed in the receiving chamber through a reaction component, so that fluorine in the water is reacted by the electro-flocculation reaction to generate flocs floating on the water. The water inlet end can be a water inlet, which can be arranged at the bottom or lower part of the reaction container 2.

[0050] Among them, the reaction component can be an electric flocculation reactor, which can be connected by a built-in power supply or an external power supply, so that it can energize the drinking water to be treated in the accommodating chamber, and realize the electric flocculation reaction of the drinking water to be treated in the accommodating chamber.

[0051] Among them, the reaction component may include a power supply and an electrode plate, wherein the electrode plate may include an anode electrode plate and a cathode electrode plate, which are electrically connected to the anode and the cathode corresponding to the power supply. The reaction component can be controlled by controlling the power supply to drive the drinking water to be treated in the accommodating chamber to undergo an electric flocculation reaction. The operation is simple, the initial investment is low, and the maintenance cost is low. It is very suitable for water treatment in rural areas and small settlements.

[0052] In this embodiment, the ultrasonic reactor 7 can be electrically connected to an external power source, and the output probe of the ultrasonic reactor 7 can be connected to the reaction component by screws, welding or bonding, for example, connected to the electrode plate of the reaction component. When the reaction component is energized so that the drinking water to be treated in the accommodating chamber undergoes an electro-flocculation reaction, part of the floccules will condense on the motor plate, causing the electrode plate to passivate and causing the reaction to be slow. The ultrasonic reactor 7 acts on the reaction component, causing the floccules on the reaction component to fall off, which can effectively clean the surface of the reaction component. By introducing the electro-flocculation method, the process energy consumption can be reduced. At the same time, the ultrasonic reactor 7 can effectively prevent the reaction component from being passivated and accelerate the reaction rate.
