[0002] With the growth of population and the acceleration of urbanization, the treatment of wastewater and waste generated by medical institutions has become an important issue in the field of environmental protection and public health. The wastewater generated by medical institutions contains a large number of pathogenic microorganisms, viruses, parasite eggs, drug residues and organic matter. If these pollutants are directly discharged into the environment without effective treatment, they will have a serious impact on water resources and ecosystems, and even threaten public health. Therefore, the research and development and application of medical wastewater treatment equipment is particularly important.

[0003] Traditional medical waste sewage treatment equipment has problems such as low treatment efficiency, high energy consumption, and high operating costs. In order to ensure safe operation and effluent treatment effects, medical institutions must be equipped with various safety devices, monitoring devices, metering devices, etc. for sewage treatment. In view of the infectiousness of sewage from medical institutions, in order to reduce the contact of operating personnel with the site and reduce the chance of infection, medical waste sewage treatment projects need to adopt a higher level of automated equipment control.

Existing sewage discharge devices have deficiencies in treatment efficiency, degree of automation and safety, which may lead to incomplete sewage treatment, causing environmental pollution and safety hazards.

[0071] The control method of the medical waste sewage treatment equipment proposed in the embodiment of the present invention can realize the efficient and automatic treatment of medical waste sewage. The various detection indicators of the treated medical waste sewage meet the environmental protection standards, avoiding potential environmental pollution and safety hazards.

[0072] In an optional embodiment of the present invention, step 11 may include:

[0073] Step 111, obtaining water quality data of sewage in the sewage treatment unit through a water quality sensor provided in the sewage treatment unit;

[0074] Step 112, obtaining liquid level data of the sewage in the sewage treatment unit through a liquid level sensor provided in the sewage treatment unit;

[0075] Step 113, obtaining flow data of sewage in the sewage treatment unit through a flow sensor provided in the sewage treatment unit;

[0076] Step 114, obtaining pressure data of the sewage in the sewage treatment unit through a pressure sensor provided in the sewage treatment unit;

[0077] Step 115, obtaining temperature data of the sewage in the sewage treatment unit through a temperature sensor disposed in the sewage treatment unit.

[0078] In this example, in order to collect various key status information of sewage in the sewage treatment unit, it is necessary to set up multiple types of sensors in the sewage treatment unit, including but not limited to water quality sensors, liquid level sensors, flow sensors, and temperature sensors; among them, the water quality sensor is a device specially designed to monitor various parameters in the water body, such as pH value, dissolved oxygen, turbidity, conductivity, heavy metal ion concentration, etc. The water quality sensor is usually installed in the sewage treatment unit to ensure that the water quality of the sewage in the pool can be fully and accurately reflected; when the water quality sensor is activated, it will detect specific components or characteristics in the sewage through internal chemical reactions or physical processes; for example, the dissolved oxygen sensor may use electrode reactions to measure the concentration of dissolved oxygen in the sewage; and the turbidity sensor may evaluate the clarity of the sewage by measuring the degree of scattering of light when passing through the sewage; the liquid level sensor is used to monitor the liquid level height of the sewage in the sewage treatment unit. The working principle of the liquid level sensor involves physical principles such as buoyancy, pressure or ultrasound. For example, the float-type liquid level sensor reflects the liquid level by the up and down floating of the float. changes; while the pressure type liquid level sensor calculates the liquid level by measuring the static pressure below the liquid surface; the ultrasonic level sensor calculates the liquid level by using the propagation speed and reflection time of ultrasonic waves in the air; the flow sensor is used to measure the flow rate of sewage during sewage treatment and is installed at the water inlet and outlet to monitor the flow of sewage; the working principles of the flow sensor include electromagnetic induction, turbine rotation, ultrasonic measurement, etc.; for example, the electromagnetic flowmeter calculates the flow rate by measuring the electromotive force generated when the fluid cuts the magnetic flux lines; the turbine flowmeter uses the rotation speed of the turbine blades in the fluid to reflect the flow rate; and the ultrasonic flowmeter calculates the flow rate by measuring the propagation time of ultrasonic waves in the fluid; the temperature sensor is used to monitor the temperature of sewage in the sewage treatment unit; temperature is one of the important factors affecting the sewage treatment effect, because different microorganisms have different activities under different temperature conditions; the working principle of the temperature sensor involves the principles of thermocouples, thermal resistors or infrared temperature measurement, and these sensors calculate the temperature value by measuring the thermal radiation or heat conduction of sewage.

[0079] In an optional embodiment, the embodiment of the present invention provides that step 12 may include:

[0080] Step 121, removing abnormal values ​​and duplicate values ​​from the water quality data, the liquid level data, the flow data, and the temperature data to obtain data after removing abnormal values ​​and duplicate values;

[0081] Step 122, converting the data after removing abnormal values ​​and duplicate values ​​to obtain standard format data;

[0082] Step 123, analyzing and processing the standard format data to obtain statistical data.

[0083] In this example, after obtaining the status data of the sewage in the sewage treatment unit, it is necessary to perform statistical processing on the status data to obtain standardized data for controller analysis, including:

[0084] Data cleaning: remove outliers, duplicate values, missing values, etc. to ensure the accuracy and completeness of the data; specifically, remove outliers and duplicate values ​​from water quality data, liquid level data, flow data, and temperature data to obtain data after removing outliers and duplicate values; outliers refer to values ​​that significantly deviate from most data points in the data set. These values ​​may be caused by measurement errors, equipment failures, or other external factors. The method for removing outliers can use the 3σ principle, that is, whether the data point is within three times the standard deviation of the mean; or standard scores to judge and remove outliers, or outliers can be identified and removed through the anomaly detection method in the machine learning algorithm; duplicate values ​​refer to data points that are exactly the same in the data set; removing duplicate values ​​can ensure the uniqueness and accuracy of the data;

[0085] Data conversion refers to the process of converting data from one format or type to another format or type. In this embodiment, the data collected by different sensors are uniformly converted into a standard format to ensure the consistency and comparability of the data. Through data conversion processing, a data set with a standard format can be obtained, which provides more convenient and accurate input for subsequent data analysis.

[0086] Finally, the data in the standard format is analyzed and processed to obtain statistical data to determine the operating status of the sewage treatment unit. Specifically, it includes: statistical analysis, calculating the average treatment efficiency and treatment time of the sewage treatment unit; trend analysis, analyzing the trend of changes in the treatment efficiency of the sewage treatment unit, such as the trend of decreased treatment efficiency; anomaly detection, detecting whether the operating data of the sewage treatment unit exceeds the normal range, such as whether the chemical oxygen demand (COD), biochemical oxygen demand (BOD), pH value and other indicators exceed the standard.

[0087] In an optional embodiment, the embodiment of the present invention provides that step 13 may include:

[0088] Step 131, comparing the statistical data with a first preset value, and when the statistical data is higher than the first preset value, generating a first control instruction, wherein the first control instruction is used to control the disinfection device to release the treatment agent and control the drainage pump to stop drainage;

[0089] Step 132, comparing the statistical data with a first preset range, and when the statistical data exceeds the first preset range, generating a second control instruction, the second control instruction being used to control the water inlet pump to perform a water inlet operation or to control the drainage pump to perform a drainage operation;

[0090] Step 133, comparing the statistical data with a second preset range, and when the statistical data exceeds the second preset range, generating a third control instruction, wherein the third control instruction is used to control the water inlet pump to perform a water inlet operation or to control the drainage pump to perform a drainage operation;

[0092] In this example, by monitoring statistical data, including key parameters such as liquid level, pressure and water quality, it is ensured that the sewage is discharged safely after the treatment meets the standards, and abnormal situations are handled in a timely manner; specifically, the sewage liquid level of the sewage treatment unit is monitored to prevent the sewage liquid level from being too high to cause overflow or too low to cause the treatment unit to dry up; the pressure of the sewage treatment unit is monitored to prevent the pressure from being too high to cause equipment damage or leakage; the effluent water quality of the sewage treatment unit is monitored to ensure that the treated sewage meets the discharge standards;

[0093] When the water quality sensor detects that the water quality index exceeds the standard (80%), that is, the statistical data is higher than the first preset value, a first control instruction is generated. The first control instruction is used to control the safety monitoring device to issue an alarm signal and initiate corresponding control measures. For example, when any value of COD, BOD, pH value, turbidity, heavy metal content, or pathogen content exceeds the standard, discharge is stopped, and a backup treatment unit is started or the treatment process is adjusted until the water quality index meets the standard.

[0094] When the liquid level sensor detects that the liquid level of the sewage treatment unit is too high or too low, that is, when the statistical data exceeds the first preset range, a second control instruction is generated, and the second control instruction is used to control the water inlet pump to perform water inlet operation or control the drainage pump to perform drainage operation, adjust the liquid level, and ensure the stability of the liquid level in the treatment pool;

[0095] When the flow sensor detects that the inlet flow or outlet flow of the sewage treatment unit is abnormal, that is, when the statistical data exceeds the second preset range, a third control instruction is generated, and the third control instruction is used to control the inlet pump to perform water intake operation or control the drainage pump to perform drainage operation, control the flow, and ensure the treatment efficiency;

[0096] When the pressure sensor detects that the pressure is over 3 bar, the safety monitoring device will send out an alarm signal and initiate corresponding control measures, for example: if the pressure is too high: control the safety valve to open and release the pressure;

[0097] When the temperature sensor detects that the temperature of the sewage treatment unit is abnormal, that is, the statistical data exceeds the third preset range, the controller generates a fourth control instruction, and the fourth control instruction is used to control the temperature control device to heat or cool the sewage in the sewage treatment unit, control the temperature, and ensure the stability of the treatment process.

[0098] A specific embodiment of the control method of medical waste water treatment equipment provided by the embodiment of the present invention is:

When the statistical data exceeds the first preset range, a second control instruction is generated, and the second control instruction is used to control the water inlet pump to perform water intake operation or control the drainage pump to perform drainage operation; the statistical data is compared with a second preset range. When the statistical data exceeds the second preset range, a third control instruction is generated, and the third control instruction is used to control the water inlet pump to perform water intake operation or control the drainage pump to perform drainage operation; the statistical data is compared with a third preset range. When the statistical data exceeds the third preset range, a fourth control instruction is generated, and the fourth control instruction is used to control the temperature control device to heat or cool the sewage in the sewage treatment unit.

[0105] Step 4: According to the control instruction, control one or more of the water inlet pump, the drainage pump, the temperature control device and the disinfection device to operate to disinfect the sewage in the sewage treatment unit.

[0106] Specifically, when the water quality sensor detects that the water quality index exceeds the standard (80%), that is, the statistical data is higher than the first preset value, a first control instruction is generated. The first control instruction is used to control the safety monitoring device to issue an alarm signal and initiate corresponding control measures. For example, when any value of COD, BOD, pH value, turbidity, heavy metal content, or pathogen content exceeds the standard, discharge is stopped, and the backup treatment unit is started or the treatment process is adjusted until the water quality index meets the standard.

[0107] When the liquid level sensor detects that the liquid level of the sewage treatment unit is too high or too low, that is, when the statistical data exceeds the first preset range, a second control instruction is generated, and the second control instruction is used to control the water inlet pump to perform water inlet operation or control the drainage pump to perform drainage operation, adjust the liquid level, and ensure the stability of the liquid level in the treatment pool;

[0109] When the pressure sensor detects that the pressure is over 3 bar, the safety monitoring device will send out an alarm signal and initiate corresponding control measures, for example: if the pressure is too high: control the safety valve to open and release the pressure;

[0110] When the temperature sensor detects that the temperature of the sewage treatment unit is abnormal, that is, the statistical data exceeds the third preset range, the controller generates a fourth control instruction, and the fourth control instruction is used to control the temperature control device to heat or cool the sewage in the sewage treatment unit, control the temperature, and ensure the stability of the treatment process.

[0125] In addition, the control system may also include a data transmission module and a touch LCD screen, wherein the data transmission module is used to transmit the collected statistical data to the server through the network (RS485, CAN bus, etc.), and the touch LCD screen is used to display the status information of the control system, that is, the real-time operating parameters of the control system are displayed through the display screen, and the operating status of the control system is displayed through the indicator light. When an abnormal situation occurs in the sewage treatment unit, an alarm message is displayed through the display screen.

[0126] The medical waste sewage treatment equipment control system provided by the present invention collects various key parameters of sewage treatment through sensors, uses control algorithms to perform real-time analysis on these data, and automatically adjusts the operating status of the treatment equipment according to the analysis results to ensure that the sewage meets the discharge standards.

[0127] like Figure 3 As shown, the embodiment of the present invention also provides a control device for medical waste water treatment equipment, including:

[0128] sewage treatment units;

[0129] Inlet pumps, outlet pumps, disinfection devices, temperature control devices and sensors installed in sewage treatment units;

[0130] A control instruction sent by a controller is received, and one or more of the water inlet pump, the drainage pump, the temperature control device and the disinfection device disinfects the sewage in the sewage treatment unit according to the control instruction; the control instruction performs statistical processing on the status data of the sewage in the sewage treatment unit to obtain statistical data; and is generated based on the statistical data.

[0131] In this example, the core of the control device of the medical waste water treatment equipment is the sewage treatment unit, wherein the sewage treatment unit includes one or more of a sewage collection tank, a grit tank, an activated sludge tank, a filtration tank, an adsorption tank, and a disinfection tank, wherein the grit tank is used to remove impurities and / or sand and gravel in the sewage, the activated sludge tank is used to degrade organic matter in the sewage, the filtration tank is used to remove suspended matter in the sewage, the adsorption tank is used to remove heavy metals and / or organic matter in the sewage, and the disinfection tank is used to kill pathogens in the sewage; the sewage treatment unit is also provided with an inlet pump, a drain pump, a disinfection device, a temperature control device and a sensor; the control device receives a control instruction sent by a controller, and one or more of the inlet pump, the drain pump, the temperature control device and the disinfection device disinfect the sewage in the sewage treatment unit according to the control instruction; the control instruction performs statistical processing on the status data of the sewage in the sewage treatment unit to obtain statistical data; and is generated according to the statistical data.

[0132] When the control device of the medical waste sewage treatment equipment is used, the sewage generated in the medical waste treatment process (such as the sewage generated by the medical waste crusher) is first collected through the sewage collection tank. After the sewage is collected by the sewage collection tank, it passes through the grille and the grit chamber to remove large particles of impurities and sand and gravel; then it enters the activated sludge tank, and the organic matter in the sewage is degraded by the microorganisms in the activated sludge; then it enters the filtration tank to remove suspended matter in the sewage; then it enters the adsorption tank to remove heavy metals, organic matter, etc. in the sewage; finally it enters the disinfection tank to kill pathogens in the sewage; the treated sewage meets the discharge standard and can be discharged into the municipal sewage network; when the water quality sensor detects that the water quality index exceeds the standard (80%), the safety monitoring device will send an alarm signal and start the corresponding control measures, for example: when any value of COD, BOD, pH value, turbidity, heavy metal content, and pathogen content exceeds the standard, the medical waste sewage treatment equipment stops discharging, and starts the standby treatment unit or adjusts the treatment process, such as adding a treatment unit. The treatment time is increased, the treatment dosage is increased, and the standby activated sludge pool and the standby disinfection pool are started at the same time until the water quality index meets the standard. When the sewage treatment fails to meet the discharge standard, the control system will stop the discharge to prevent environmental pollution. When the liquid level sensor detects that the liquid level is too high (80%), the safety monitoring device will send out an alarm signal and start the corresponding control measures, for example: when the liquid level is too high, the drain valve is controlled to open and the liquid level is lowered; when the pressure sensor detects that the pressure is too high by more than 3 bar, the safety monitoring device will send out an alarm signal and start the corresponding control measures, for example: when the pressure is too high, the safety valve is controlled to open and the pressure is released; when the flow sensor detects that the inlet flow or outlet flow of the sewage treatment unit is abnormal, the medical waste sewage treatment equipment will adjust the inlet valve or the drain valve to control the flow and ensure the treatment efficiency; when the temperature sensor detects that the temperature of the sewage treatment unit is abnormal, the medical waste sewage treatment equipment will adjust the heating or cooling system to control the temperature and ensure the stability of the treatment process.
