[0047] Wastewater treatment is to purify and treat wastewater generated from industrial, agricultural, urban life and other activities to reduce pollution to the environment. Hydrogen energy is a renewable energy source, and hydrogen energy is produced by electrolysis of water. Compared with other highly polluting and difficult to degrade wastewater, the wastewater produced by electrolysis of water is relatively clean, with fewer types of pollutants. It is mainly composed of cooling tower wastewater and desalted water station wastewater. The water quality is characterized by high salt content and high hardness, and fewer other pollutants. Softening precipitation is mainly used.

[0048] Softening precipitation refers to adding chemical agents, such as PAC, PAM and other flocculants, to the wastewater to be treated to remove part of the suspended matter in the water by precipitating it through charge neutralization, adsorption bridging, precipitation and other effects. In the prior art, chemical agents are mainly added to the wastewater to be treated manually. However, it is difficult to quickly and accurately add the appropriate amount of agents according to the changing wastewater quality when adding artificially synthesized agents. Excessive addition causes waste of agents, and too little addition causes substandard water quality, resulting in unstable effluent quality.

When the water quality of the water inlet area is greater than the first preset value, the control unit controls the second configuration unit to communicate with the water inlet area, transports the reagent to the water inlet area, and preliminarily mixes with the wastewater of hydrogen production by electrolysis of water transported to the water inlet area, and then flows into the reaction area to be fully mixed, so that the reagent and the wastewater are fully reacted, and the purified wastewater flows into the water outlet area. When the water quality of the water outlet area is greater than the second preset value, the control unit controls the first configuration unit and the second configuration unit to adjust the amount of reagent added, thereby adjusting the amount of reagent added according to the change of water quality. Therefore, the device is convenient for controlling the amount of reagent added to stabilize the water quality of the outlet water.

[0051] The present application provides a wastewater treatment device for producing hydrogen by electrolysis of water, comprising: a reagent configuration unit 100, a detection unit 200, a reaction unit 300 and a control unit 400; the reagent configuration unit 100 comprises a first configuration unit 110, a second configuration unit 120 and a reagent weighing platform 130, the outlet of the first configuration unit 110 is connected to the inlet of the second configuration unit 120, and the reagent weighing platform 130 is arranged on one side of the first configuration unit 110 or the second configuration unit 120. The reaction unit 300 comprises a water inlet area 310, a reaction area 320 and a water outlet area 330 which are connected in sequence, the outlet of the second configuration unit 120 is connected to the inlet of the water inlet area 310, and the water inlet area 310 is connected to the outlet of the wastewater storage container. The detection unit 200 includes a first detection member 210 and a second detection member 220, wherein the first detection member 210 is used to detect the water quality of the water inlet area 310, and the second detection member 220 is used to detect the water quality of the water outlet area 330; the first configuration unit 110, the second configuration unit 120, the first detection member 210 and the second detection member 220 are all electrically connected to the control unit 400. The control unit 400 is configured to control the second configuration unit 120 to communicate with the water inlet area 310 when the water quality of the water inlet area 310 is greater than a first preset value; and control the first configuration unit 110 and the second configuration unit 120 to release the medicine when the water quality of the water outlet area 330 is greater than a second preset value, and the first preset value is greater than the second preset value.

[0052] In specific implementation, the medicine weighing platform 130 is arranged on one side of the first configuration unit 110 or the second configuration unit 120 for weighing the medicine. The weighed medicine is put into the first configuration unit 110 and the second configuration unit 120. Exemplarily, the medicine weighing platform 130 is input into the first configuration unit 110 or the second configuration unit 120 through a pipeline, and an extraction pump is arranged on the pipeline. The medicine weighing platform 130 is electrically connected to the control unit 400. When the control unit 400 detects that the medicine weighing platform 130 reaches a preset weight value, it controls the extraction pump to start and put the medicine into the first configuration unit 110 or the second configuration unit 120. It should be noted that the weighed medicine can also be manually put into the first configuration unit 110 or the second configuration unit 120.

[0053] In order to facilitate monitoring of changes in wastewater quality, the device also includes a first detection member 210 and a second detection member 220. The first detection member 210 can be set at a stable water flow on the side wall of the wastewater inflow end of the water inlet area 310 to feed back the detection result of the wastewater quality to be treated to the control unit 400, and the control unit 400 controls the dosage or dosage concentration of the first configuration unit 110 and the second configuration unit 120. The second detection member 220 can be set at a stable water flow on the side wall of the water outlet area 330 to detect in real time whether the water hardness of the water outlet area 330 meets the standard, and feed back the detection result to the control unit 400. Exemplarily, when the water quality of the water outlet area 330 is greater than the second preset value, the control unit 400 adjusts the concentration or dosage of the first configuration unit 110 and the second configuration unit 120. It can be understood that the first preset value and the second preset value can be set according to actual conditions, such as reference to the water quality standard, and the present application does not limit this.

[0054] It should be noted that, in order to facilitate the control of the dosage concentration according to the wastewater quality, the first configuration unit 110 can be a high-concentration agent configuration unit, and the second configuration unit 120 can be a low-concentration agent configuration unit, and the agent concentration can be increased or decreased by matching the high-concentration agent with the low-concentration agent. For example, when the wastewater quality is poor, the agent concentration is increased by increasing the input amount of the high-concentration agent.

[0055] In the wastewater treatment device for producing hydrogen by electrolysis of water in the embodiment of the present application, the reagent configured by the first configuration unit 110 is transported to the second configuration unit 120 for mixing. When the water quality of the water inlet area 310 is greater than the first preset value, the control unit 400 controls the second configuration unit 120 to communicate with the water inlet area 310; the reagent is transported to the water inlet area 310, preliminarily mixed with the wastewater produced by electrolysis of water in the water inlet area 310, and then flows into the reaction area 320 for full mixing, so that the reagent and the wastewater are fully reacted, and the purified wastewater flows into the water outlet area 330. When the water quality of the water outlet area 330 is greater than the second preset value, the control unit 400 controls the first configuration unit 110 and the second configuration unit 120 to adjust the amount of reagent added, thereby adjusting the amount of reagent added according to the change in water quality. As a result, the device is convenient for controlling the amount of reagent added to stabilize the water quality of the outlet water.

[0056] In some embodiments, the wastewater treatment device for producing hydrogen by electrolysis of water provided in the present application, the first configuration unit 110 includes a first medicine dispensing box 111 and a first water inlet pipe 112, the first medicine dispensing box 111 has a accommodating chamber 113, the accommodating chamber 113 has a first agitator 114, the water inlet pipe 112 is connected to the accommodating chamber 113, and the outlet of the accommodating chamber 113 is connected to the second configuration unit 120.

[0057] In specific implementation, the first water inlet pipe 112 is disposed on one side of the first medicine dispensing box 111, and the first water inlet pipe 112 is connected to the receiving chamber 113 of the first medicine dispensing box 111. The receiving chamber 113 is used to provide mixing and reaction of liquids, and the first stirrer 114 is used to stir and flow the liquids.

[0058] When in use, the first water inlet pipe 112 inputs the liquid into the containing chamber 113, and the liquid is stirred in the containing chamber 113 by the first stirrer 114 to ensure the mixing and reaction of the liquid and the medicine. The outlet of the containing chamber 113 is connected to the second configuration unit 120 to input the mixed medicine into the second configuration unit 120.

[0059] In some embodiments, the first medicine dispensing box 111 can be a high-concentration medicine dispensing box, which facilitates the first agitator 114 to fully stir and mix the external medicine dispensing water, such as tap water or desalted water, transported by the first water inlet pipe 112 with the medicine in the containing cavity 113 to obtain a high-concentration medicine solution.

[0060] In some embodiments, the wastewater treatment device for producing hydrogen by electrolysis of water provided in the present application, the second configuration unit 120 includes a second medicine dispensing box 121, a second water inlet pipe 122 and a plurality of metering pumps 125, the second medicine dispensing box 121 has a configuration chamber 123, the configuration chamber 123 has a second agitator 124, the second water inlet pipe 122 is connected to the configuration chamber 123, the outlet of the configuration chamber 123 is connected to the inlet of the water inlet area 310, and each metering pump 125 is arranged at the inlet and outlet of the second medicine dispensing box 121, and the metering pump 125 is used to control the water inlet amount of the first water inlet pipe 112, the medicine output of the first configuration unit 110 and the medicine output of the second medicine dispensing box 121.

[0061] When in use, the second water inlet pipe 122 inputs liquid into the configuration chamber 123, and the first configuration unit 110 inputs the mixed liquid into the configuration chamber 123. The second stirrer 124 stirs the liquid input from the second water inlet pipe 122 and the liquid input from the first configuration unit 110 so as to mix or react.

[0062] The outlet of the configuration chamber 123 is connected to the inlet of the water inlet area 310, and liquid can be input into the water inlet area 310 to treat wastewater. Each metering pump 125 is used to control the water inflow of the first water inlet pipe 112, the drug output of the first configuration unit 110, and the drug output of the second drug dispensing box 121 to achieve the ratio of drug concentration.

[0063] In some embodiments, the second drug dispensing box 121 may be a low-concentration drug dispensing box, which is not limited in the present application.

[0064] In some embodiments, the wastewater treatment device for producing hydrogen by electrolysis of water provided in the present application further includes a plurality of switch components 500 , each of which is arranged at the outlet and the inlet of the first drug dispensing box 111 and the second drug dispensing box 121 .

[0065] In specific implementation, each switch assembly 500 is arranged at the outlet and inlet of the first medicine dispensing box 111 and the second medicine dispensing box 121 to control the flow of liquid and the proportion of the medicine. The switch assembly 500 can open or close the flow channel of the liquid according to the water quality and the demand for increasing or decreasing the medicine to ensure the correct configuration and flow of the liquid. The switch assembly 500 can realize the control and regulation of the liquid through equipment such as solenoid valves, pneumatic valves, and pneumatic pumps, and this application does not limit this.

[0066] In some embodiments, in the wastewater treatment device for producing hydrogen by electrolysis of water provided in the present application, the switch assembly 500 is a manual ball valve switch 510 and a solenoid valve switch 520 arranged in sequence, and the manual ball valve switch 510 is a normally open switch.

[0067] In specific implementation, the manual ball valve switch 510 is a normally open switch, that is, when no force is applied, the passage of the ball valve is always in an open state. When the manual ball valve switch 510 is rotated to a specific angle, the passage of the ball valve will be closed, thereby preventing the flow of liquid.

[0068] The solenoid valve switch 520 can realize the opening or closing of the solenoid valve through the control signal of the control unit 400, so as to open or close the flow channel of the liquid according to the water quality and the demand for increase or decrease of the medicine, thereby realizing automatic control.

[0069] In some embodiments, in the wastewater treatment device for producing hydrogen by electrolysis of water provided in the present application, the switch assembly 500 also includes an electromagnetic flowmeter 530, which is used to detect the drug output flow rate or water inlet flow rate at the outlet and inlet of the first drug dispensing box 111 and the second drug dispensing box 121. The electromagnetic flowmeter 530 is electrically connected to the solenoid valve switch 520, the metering pump 125 and the control unit 400, respectively.

[0070] In specific implementation, the electromagnetic flowmeter 530 is used to detect the drug outflow rate or water inflow rate at the outlet and inlet of the first medicine dispensing box 111 and the second medicine dispensing box 121, so as to control the solenoid valve switch 520 and the metering pump 125 to open or close the liquid flow channel through the control unit 400 according to the water quality and the demand for increasing or decreasing the medicine.

[0071] In some embodiments, the wastewater treatment device for producing hydrogen by electrolysis of water provided in the present application further includes a plurality of ultrasonic level meters 600. The first configuration unit 110 and the second configuration unit 120 are both provided with ultrasonic level meters 600. The ultrasonic level meters 600 are used to detect the liquid level of the first configuration unit 110 or the second configuration unit 120. The ultrasonic level meters 600 are electrically connected to the control unit 400. When the liquid level of the first configuration unit 110 or the second configuration unit 120 is greater than the preset liquid level value, the control unit 400 controls the switch assembly 500 to close and controls the first agitator 114 or the second agitator 124 to turn on.

[0072] It should be noted that the ultrasonic liquid level meter 600 includes a transmitter and a receiver. The transmitter transmits an ultrasonic signal, which is reflected by the liquid. The receiver receives the reflected ultrasonic signal and feeds back the collected data to the control unit 400. The control unit compares the data with the preset liquid level value, thereby controlling the first agitator 114 or the second agitator 124 to turn on or off.

[0073] In some embodiments, in the wastewater treatment device for producing hydrogen by electrolysis of water provided in the present application, the outlet and inlet of the first drug dispensing box 111 and the second drug dispensing box 121 are both provided with a filter element 140, and the filter element 140 is used to filter debris.

[0074] In a specific implementation, there are multiple filters 140, which are arranged at the outlet and inlet of the first medicine dispensing box 111 and the second medicine dispensing box 121, and are used to filter debris. The filter 140 can be a Y-type filter, which is not limited in the present application.

[0075] In some embodiments, the wastewater treatment device for producing hydrogen by electrolysis of water provided in the present application further includes a flow-pushing member 340 , which is disposed at the inlet or outlet of the reaction zone 320 , and is used to accelerate the flow of liquid in the reaction zone 320 .

[0076] In specific implementation, the flow-pushing member 340 can be a liquid propulsion structure that pushes the liquid from one end to the other end, thereby realizing the flow of the liquid and enhancing the full reaction of the chemical agent and the wastewater. The flow-pushing member 340 can be arranged at the inlet end or the outlet end of the reaction zone 320, and the flow-pushing direction of the flow-pushing member 340 is consistent with the flow direction of the liquid, that is, from the water inlet zone 310 to the water outlet zone 330 through the reaction zone 320.

[0077] Exemplarily, the flow-pushing member 340 includes a driver and a rotating blade. The driver drives the rotating blade to rotate. The rotating blade forms a rotating vortex during the rotation process, pushing the liquid from the inlet end of the reaction zone 320 to the outlet end. The driver can be a motor. It should be noted that the flow rate of the liquid in the reaction zone 320 can be controlled by adjusting the rotation speed and the number of blades of the rotating blade. The number of the flow-pushing member 340 can be one or more, and this application does not limit this. Exemplarily, Figure 1 and Figure 2 As shown, there may be two flow-pushing members 340 , which are respectively disposed at the inlet and outlet of the reaction zone 320 .

[0078] In some embodiments, the flow-pushing member 340 may be a flow-pushing device, which is not limited in the present application.

[0079] In some embodiments, in the wastewater treatment device for producing hydrogen by electrolysis of water provided in the present application, the first detection component 210 and the second detection component 220 both include at least one of a water hardness detector, a pH meter, a turbidity meter, and a thermometer.

[0080] In specific implementation, the water hardness tester is used to measure the total water hardness in the water, that is, the total amount of alkaline salts in the water. For example, the water hardness is between 100-200 mg / L as the appropriate range. If the water hardness is too high, it is necessary to increase the concentration of the reagent or perform softening treatment. Too high or too low water hardness will affect the solubility of elements in the water, thereby affecting the purification effect of the chemical flocculant, and then affecting the effluent water quality.

[0081] The pH meter is used to measure the pH value in water, that is, the acidity and alkalinity of water. For example, the pH value is between 6.5-8.5. The turbidity meter is mainly used to measure the turbidity in water, that is, the concentration of impurities in water. The lower the turbidity, the better the water quality.
