Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, and in particular to a multi-sensor remote control device for wastewater treatment. Background Technology

[0002] Wastewater treatment refers to the process of purifying wastewater to meet the water quality requirements for discharge into a water body or for reuse. Based on the nature of the pollutants, water pollution can be divided into two categories: natural pollution and anthropogenic pollution. Currently, anthropogenic pollution poses a greater threat to water bodies. Water pollution can be mainly classified into three categories based on the different pollutants: chemical pollution, physical pollution, and biological pollution. The main pollutants include: 1. Untreated industrial wastewater; 2. Untreated domestic sewage; 3. Agricultural wastewater from the extensive use of fertilizers, pesticides, and herbicides; 4. Industrial waste and domestic garbage piled up along riverbanks; 5. Soil erosion; 6. Mine wastewater. Wastewater treatment is widely used in various fields such as construction, agriculture, transportation, energy, petrochemicals, environmental protection, urban landscaping, medical care, and catering, and is increasingly becoming a part of everyday life for ordinary people.

[0003] Many existing wastewater treatment devices use quantitative dosing of chemicals to treat wastewater. While this method can automate the operation of the equipment, the pollutants in the wastewater are variable, which may lead to either excessive addition of chemicals, resulting in wasted costs, or insufficient addition of chemicals, resulting in substandard treatment effects and unstable wastewater quality. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of existing sewage treatment devices that mostly use quantitative dosing of chemicals to treat sewage. Although this method can realize the automated operation of the equipment, the pollutants in the sewage are variable, which may lead to excessive addition of chemicals, resulting in cost waste, or insufficient addition of chemicals, resulting in substandard treatment effect and unstable sewage quality. This utility model provides a multi-sensor remote control device for sewage treatment.

[0005] The purpose of this utility model is achieved through the following technical solution: a multi-sensor remote control device for sewage treatment, including an inlet pipe, the outlet of the inlet pipe being connected to the inlet of two treatment tanks respectively through two sets of branch pipes, a first solenoid valve and a flow meter being installed on the branch pipes, a chemical tank being installed on each of the two treatment tanks, a diaphragm metering pump being installed at the outlet of the chemical tank, and the outlet of the diaphragm metering pump extending into the treatment tank;

[0006] A sensor assembly is installed inside the water inlet pipe, which includes a COD sensor and a pH sensor.

[0007] The diaphragm metering pump, COD sensor, pH sensor, first solenoid valve, and flow meter are all connected to an external control center. The external control center is responsible for controlling the opening and closing of the diaphragm metering pump and the first solenoid valve. By connecting the diaphragm metering pump, COD sensor, pH sensor, first solenoid valve, and flow meter to the external control center, it is convenient for staff to remotely monitor the operation of the equipment and the parameters of each sensor, and to control the equipment, thereby improving processing efficiency.

[0008] By combining COD and pH sensors, the system can continuously monitor the COD and pH values ​​of wastewater in the treatment tank in real time. It assesses the content of organic pollutants and the pH value of the water and sends the data to a remote external control center. Staff at the control center can then determine the wastewater treatment effect, decide whether to continue adding chemicals via a diaphragm metering pump, and control the amount of chemicals added. This ensures controllable chemical addition, meeting wastewater treatment standards while avoiding excessive dosage and cost waste, thus improving the stability of the treated wastewater quality.

[0009] A further technical solution involves installing a level gauge inside the inlet pipe, which is connected to an external control center. By setting the level gauge, the amount of wastewater in the treatment tank can be measured. The external control center can determine whether there is any abnormality in the equipment by checking whether the measurement results of the level gauge and the diaphragm metering pump are consistent, and can estimate the amount of reagent to be added to avoid waste caused by excessive addition of reagent.

[0010] A further technical solution involves installing a motor at the top of the inlet pipe. The motor's power output extends into the inlet pipe and is equipped with multiple sets of stirring rods. The motor is connected to an external control center. By setting the motor to drive the stirring rods to stir, the agent can be evenly distributed in the sewage, further improving the treatment effect of the agent on the sewage.

[0011] A further technical solution is that the sensor assembly also includes a temperature sensor connected to an external control center. An electric heating tape is installed on the outer wall of the inlet pipe and is connected to the external control center, which is responsible for controlling the opening and closing of the electric heating tape. By setting the temperature sensor, the temperature of the sewage in the treatment tank can be detected. When the environment is cold, the external control center can control the electric heating tape to heat the sewage in the treatment tank, so as to avoid the sewage temperature being too low and the reaction between the sewage and the agent being too slow, thereby improving the sewage treatment efficiency in low temperature environments.

[0012] A further technical solution is to design the bottom of the treatment tank as an arc shape, with a second solenoid valve connected to an external control center installed at the outlet end of the bottom of the treatment tank. A drain pipe is installed at the outlet end of the second solenoid valve. By designing the bottom of the treatment tank as an arc shape, the treated wastewater inside the treatment tank can be completely discharged, preventing any residue from remaining inside the treatment tank.

[0013] This invention has the following advantages: By combining a COD sensor and a pH sensor, it can continuously monitor the COD and pH values ​​of the wastewater in the treatment tank in real time, assess the content of organic pollutants and the pH value of the water, and send the data to a remote external control center. The staff at the external control center can then determine the wastewater treatment effect, decide whether to continue adding chemicals via a diaphragm metering pump, and control the amount of chemicals added. This achieves controllability of chemical addition, ensuring that the amount of chemicals added meets wastewater treatment standards while avoiding excessive chemical addition that would lead to cost waste, and improving the stability of the equipment in terms of wastewater quality.

[0023] like Figures 1-2 As shown, a multi-sensor remote control device for wastewater treatment includes an inlet pipe 1. The outlet end of the inlet pipe 1 is connected to the inlet ends of two treatment tanks 2 via two sets of branch pipes 3. A first solenoid valve 11 and a flow meter 12 are installed on the branch pipes 3. A chemical tank 4 is installed on each of the two treatment tanks 2. A diaphragm metering pump 5 is installed at the outlet end of the chemical tank 4. The outlet end of the diaphragm metering pump 5 extends into the treatment tank 2.

[0024] A sensor assembly 6 is installed inside the water inlet pipe 1. The sensor assembly 6 includes a COD sensor 601 and a pH sensor 602.

[0025] The diaphragm metering pump 5, COD sensor 601, pH sensor 602, first solenoid valve 11, and flow meter 12 are all connected to an external control center. The external control center is responsible for controlling the opening and closing of the diaphragm metering pump 5 and the first solenoid valve 11. By connecting the diaphragm metering pump 5, COD sensor 601, pH sensor 602, first solenoid valve 11, and flow meter 12 to an external control center, it is convenient for staff to remotely monitor the operation of the equipment and the parameters of each sensor, and to control the equipment, thereby improving processing efficiency.

[0026] By using a combination of COD sensor 601 and pH sensor 602, the COD and pH values ​​of the wastewater in treatment tank 2 can be continuously monitored in real time. This allows for the assessment of the organic pollutant content and pH value in the water, which is then transmitted to a remote external control center. Staff at the external control center can then determine the wastewater treatment effect, whether to continue adding chemicals via diaphragm metering pump 5, and control the amount of chemicals added. This ensures controllability of chemical addition, meeting wastewater treatment standards while avoiding excessive chemical addition that would lead to cost waste, thus improving the stability of the equipment in treating wastewater quality.

[0027] A level gauge 7 is installed inside the inlet pipe 1. The level gauge 7 is connected to the external control center. By setting the level gauge 7, the amount of sewage in the treatment tank 2 can be measured. The external control center can determine whether the equipment is abnormal by whether the measurement results of the level gauge 7 and the diaphragm metering pump 5 are consistent, and estimate the amount of reagent to be added to avoid waste caused by excessive addition of reagent.

[0028] A motor 9 is installed at the upper part of the inlet pipe 1. The power output end of the motor 9 extends into the inlet pipe 1 and is equipped with multiple sets of stirring rods 10. The motor 9 is connected to an external control center. By setting the motor 9 to drive the stirring rods 10 to stir, the agent can be evenly distributed in the sewage, thereby further improving the treatment effect of the agent on the sewage.

[0029] The sensor assembly 6 also includes a temperature sensor 603 connected to an external control center. An electric heating tape 8 is installed on the outer wall of the inlet pipe 1. The electric heating tape 8 is connected to the external control center, which is responsible for controlling the opening and closing of the electric heating tape 8. By setting the temperature sensor 603, the temperature of the sewage in the treatment tank 2 can be detected. When the environment is cold, the external control center can control the electric heating tape 8 to heat the sewage in the treatment tank 2, so as to avoid the sewage temperature being too low and the reaction between the sewage and the agent being too slow, thereby improving the sewage treatment efficiency in low temperature environments.

[0030] The bottom of the treatment tank 2 is arc-shaped. A second solenoid valve 13 connected to an external control center is installed at the liquid outlet of the bottom of the treatment tank 2. A drain pipe 14 is installed at the liquid outlet of the second solenoid valve 13. By setting the bottom of the treatment tank 2 to be arc-shaped, the treated wastewater in the treatment tank 2 can be discharged cleanly, avoiding residue in the treatment tank 2.

[0031] The working process of this utility model is as follows: First, the operator controls the first solenoid valve 11 to open via the external control center to add sewage into one of the treatment tanks 2. The flow meter 12 is responsible for measuring the amount of sewage added. When a certain amount is added, the first solenoid valve 11 closes. The operator can then observe whether the measurement data of the first solenoid valve 11 and the liquid level gauge 7 in the treatment tank 2 are consistent or have a large deviation. When the measurement data are basically consistent, the operator can control the diaphragm metering pump 5 to add 80% of the dosage of the medicine according to the measurement data. At this time, the operator controls the motor 9 to drive the stirring rod 10 to stir. The operator monitors the data of the COD sensor 601 and the pH sensor 602 via the external control center. When the water is stable, staff assess the content of organic pollutants and the pH value of the water and send the data to a remote external control center. Staff at the external control center then determine the effectiveness of the wastewater treatment and whether to continue adding chemicals via the diaphragm metering pump 5. When the first solenoid valve 11 is closed, another set of first solenoid valves 11 can be opened to add wastewater to another set of treatment tanks 2. The above steps are repeated to increase the treatment volume and efficiency of the wastewater. When the data from the COD sensor 601 and pH sensor 602 monitored by the external control center indicate that the wastewater meets the discharge standards, the second solenoid valve 13 is controlled to discharge the treated wastewater from the treatment tank 2 into the drain pipe 14.

[0032] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
