[0081] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0083] Reference Figure 1 , a sewage removal method, comprising the following steps:

[0084] Step 100: Obtain the turbidity of water in the water meter pipe.

[0085] Water turbidity refers to the turbidity of the water in the water meter pipe. The water turbidity can be obtained by a turbidity meter. The method for obtaining the water turbidity is selected by the staff based on actual conditions and will not be elaborated here.

[0086] Step 101: When the turbidity of the water body falls into a preset turbidity range, the adsorption time is matched from a preset adsorption time matching model according to the turbidity of the water body.

[0087] The dirty interval refers to the pre-set turbidity value interval of the water body where the turbidity is too high. The dirty interval is selected by the staff according to the actual situation and will not be described here. If the turbidity of the water body falls into the dirty interval, it means that the turbidity of the water body is too high and the water in the water meter pipe is relatively turbid.

[0088] Adsorption filter element refers to a device used to absorb suspended matter in water. Adsorption filter element generally adopts polypropylene melt-blown filter element. Adsorption filter element is selected by staff according to actual situation, which will not be described in detail here. Adsorption time matching model refers to a neural network model obtained through sample training in advance. Adsorption time matching model can match the adsorption time required to reduce the turbidity of water to below the dirty range through adsorption filter element.

[0089] Step 102: Control the preset filter element switching device to switch the preset adsorption filter element into the water meter pipe according to the adsorption time, and obtain the adsorption turbidity in the water meter pipe.

[0090] The filter element switching device is used to switch the position of the filter element so that the filter element can be switched to the inside of the pipe, inside the water meter or outside the water meter as needed. The filter element switching device is selected by the staff according to the actual situation and will not be described here. The adsorption filter element is switched to the pipe through the filter element switching device to absorb the suspended matter in the water body through the adsorption filter element, thereby reducing the turbidity of the water body.

[0091] Adsorption turbidity refers to the turbidity of the water obtained after the adsorption filter element is switched into the pipeline through the filter element switching device. The adsorption turbidity can be obtained by a turbidity meter. The method for obtaining the adsorption turbidity is selected by the staff according to the actual situation and will not be elaborated here.

[0092] Step 103: When the adsorption turbidity falls into a preset clean range, a preset disinfection device is controlled to irradiate the water body.

[0093] The clean interval refers to the pre-set turbidity value interval of the water body with lower turbidity. The clean interval is selected by the staff according to the actual situation, and will not be elaborated here. The adsorption turbidity falling into the clean interval means that the adsorption turbidity is low and the water in the water meter pipe is relatively clear.

[0094] The disinfection device refers to a device that kills bacteria and microorganisms in the water body through ultraviolet rays. The disinfection device is selected by the staff according to the actual situation and will not be described here. The turbidity of the water body is reduced by the adsorption filter element, and the bacteria and microorganisms in the water body are killed by the disinfection device, thereby converting the sewage in the water meter pipe into clean water, thereby reducing the output of sewage from the water meter.

[0095] Among them, the sterilization and disinfection effect of ultraviolet rays on water bodies is generally controlled by controlling the effective dose of ultraviolet rays. The calculation formula of the effective dose of ultraviolet rays can be UV = I0 × e -αc ×t, where UV is the effective dose of ultraviolet light emitted by the disinfection device, I0 is the initial light intensity of the ultraviolet light emitted by the disinfection device, α is the attenuation coefficient of ultraviolet light in the water body, c is the turbidity of the water body, and t is the irradiation time of ultraviolet light.

[0096] Among them, α can be obtained through sample testing, and the calculation formula of α is: Obtain, d refers to the distance that the ultraviolet light passes through the water sample, I refers to the ultraviolet light intensity measured in the water sample after passing a certain distance, and I0 refers to the initial light intensity of the ultraviolet light emitted by the disinfection device.

[0097] Reference Figure 2 , the filter element replacement method includes the following steps:

[0098] Step 200: Obtain switching time.

[0099] The switching time refers to the time elapsed after the filter element switching device switches the adsorption filter element to the pipeline. The switching time can be obtained through a timer. The method for obtaining the switching time is selected by the staff according to actual conditions and will not be elaborated here.

[0100] Step 201: matching the adsorption rate from a preset adsorption rate calculation model according to the water turbidity, switching time and adsorption turbidity.

[0101] The adsorption rate calculation model refers to a neural network model obtained in advance through sample training. The adsorption rate calculation model can calculate the rate of change of turbidity of water from water body turbidity to adsorption turbidity over time within the switching time. The adsorption rate is the rate of change calculated by the adsorption rate calculation model.

[0102] Step 202: When the adsorption rate falls into a preset filter element failure interval, the preset filter element switching device is controlled to switch the preset adsorption filter element to the outside of the water meter, and a filter element image of the filter element is obtained.

[0103] The filter failure interval refers to the adsorption rate value interval where the adsorption efficiency of the adsorption filter is low. The filter failure interval is selected by the staff according to the actual situation and will not be described here. The adsorption rate falling into the filter failure interval means that the adsorption efficiency of the adsorption filter is low, that is, the time required to purify the water through the adsorption filter is too long.

[0104] The filter element image refers to the picture of the adsorption filter element obtained after the filter element switching device switches the adsorption filter element to the outside of the water meter. The filter element image can be obtained through a camera. The method for obtaining the filter element image is selected by the staff according to actual conditions and will not be elaborated here.

[0105] Step 203: judging whether the filter element is invalid from a preset filter element state recognition model according to the filter element image.

[0106] The filter element state recognition model refers to a neural network model obtained through sample training in advance. The filter element state recognition model can judge the state of the filter element according to the color of the filter element in the filter element image, thereby judging whether the filter element is invalid.

[0107] Step 204: When the filter element fails, a replacement itinerary is matched from a preset replacement itinerary matching model according to the filter element image.

[0108] The filter element replacement device refers to a device used to replace the filter element.

The replacement stroke matching model refers to a neural network model obtained through sample training in advance. The replacement stroke matching model can match the replacement stroke of replacing the failed adsorption filter element with a valid new adsorption filter element through the filter element replacement device.

[0109] Step 205: Control the preset filter element replacement device to replace the adsorption filter element according to the replacement stroke, and control the preset filter element switching device to switch the adsorption filter element to the water meter pipeline.

[0110] By detecting the turbidity changes of the water in the water meter pipe, the working status of the adsorption filter element can be judged, so that the filter element can be replaced in time when the filter element fails, and the suspended matter in the water body can continue to be adsorbed by the new adsorption filter element.

[0111] Reference Figure 3 , the sewage discharge method comprises the following steps:

[0112] Step 300: When the filter element is effective, the volume of water in the water meter pipe is obtained.

[0113] The filter element is effective, which means that the adsorption effect of the adsorption filter element on the suspended solids in the water body is low. The water volume refers to the volume of the water in the water meter pipe. The water volume can be obtained by querying the water meter parameters according to the water meter model. The method of obtaining the water volume is selected by the staff according to the actual situation, which will not be elaborated here.

[0114] Step 301: Match the drainage time from a preset drainage time matching model according to the water volume.

[0115] The drain valve refers to a valve installed on the water meter to discharge the water in the water meter pipe into the sewer for disposal. The drain valve is selected by the staff according to the actual situation and will not be described here. The drainage time matching model refers to a neural network model obtained through sample training in advance. The drainage time matching model can match the drainage time required to completely discharge the water in the water meter pipe through the drain valve.

[0116] Step 302: Control the opening and closing of the sewage valve preset on the water meter according to the drainage time, and match the cleaning times from the preset cleaning times matching model according to the adsorption turbidity.

[0117] The water meter cleaning method refers to a method of flushing the water meter pipe with clean water to reduce the residual sewage. The cleaning times matching model refers to a neural network model obtained through sample training in advance. The cleaning times matching model can match the cleaning times required to clean the residual turbidity adsorbed sewage in the water meter pipe through the water meter cleaning method.

[0118] Step 303: Clean the water meter according to a preset water meter cleaning method based on the cleaning times.

[0119] When the adsorption effect of the adsorption filter element on suspended solids in the water body is low, it takes a long time to reduce the turbidity of the water body through the adsorption filter element. At this time, the sewage is discharged through the sewage valve, and the residual sewage in the water meter pipe is reduced through the water meter cleaning method, and then fresh water is injected into the water meter, thereby reducing the sewage output of the water meter.

[0120] Reference Figure 4 , the water meter cleaning method includes the following steps:

[0121] Step 400: Match the disinfection dose from a preset disinfection dose matching model according to the adsorption turbidity and the number of cleaning times.

[0122] Disinfectant refers to an agent used to sterilize and clean the inner wall of the water meter pipe. The disinfectant can be chlorine dioxide. The disinfectant is selected by the staff according to the actual situation and will not be described here. The disinfection dose matching model refers to a neural network model obtained through sample training in advance. The disinfection dose matching model can match the dose of disinfectant required to clean the sewage with adsorbed turbidity, and then evenly distribute the dose to each cleaning process according to the number of cleanings. The disinfection dose is the dose of disinfectant required for each cleaning matched by the disinfection dose matching model.

[0123] Step 401: Control a preset injection device according to the disinfection dosage to inject a preset disinfectant into a water meter, and match the water injection time from a preset water injection time matching model according to the water volume.

[0124] The injection device refers to a device used to inject disinfectant into the water meter pipe. The injection device is selected by the staff according to the actual situation and will not be described in detail here. The water inlet valve refers to a valve installed on the water meter to inject clean water into the water meter pipe. The water inlet valve is selected by the staff according to the actual situation and will not be described in detail here. The water injection time matching model refers to a neural network model obtained through sample training in advance. The water injection time matching model can match the water injection time required to fill the water meter pipe with clean water through the water inlet valve.

[0125] Step 402: Control the opening and closing of the water inlet valve preset on the water meter according to the water injection time.

[0126] Fill the water meter pipe with clean water through the water inlet valve.

[0127] Step 403: Match the disinfection time from a preset disinfection time matching model according to the adsorption turbidity.

[0128] The disinfection time matching model refers to a neural network model obtained through sample training in advance. The disinfection time matching model can match the disinfection time required for the disinfectant to fully react with the sewage with adsorbed turbidity.

[0129] Step 404: Control the preset water inlet valve and sewage valve to close according to the disinfection time, and control the preset sewage valve to open and close according to the drainage time.

[0130] Disinfectant and clean water are injected into the water meter pipe to form a cleaning liquid, and the cleaning liquid is allowed to fully react with the bacteria and microorganisms in the water meter pipe according to the disinfection time to improve the disinfection effect of the cleaning liquid, and the cleaning liquid is discharged through the drain valve after the disinfection time.

[0131] Reference Figure 5 , the metal ion removal method comprises the following steps:

[0132] Step 500: After the disinfection device irradiates the water body, the preset metal measuring device is controlled to extend into the water body and obtain the measuring current.

[0133] The metal measuring device refers to a device used to measure the metal ion concentration of the water in the water meter pipe. The metal measuring device generally includes an oxidizing electrode and a reducing electrode, and the oxidizing electrode and the reducing electrode are connected by a wire. The oxidizing electrode and the reducing electrode are simultaneously extended into the water body to cause an oxidation-reduction reaction between the water body and the metal measuring device, thereby generating a current in the wire, and judging the concentration of the metal ion by the magnitude of the current. The materials of the oxidizing electrode and the reducing electrode are selected by the staff according to the type of metal ion to be measured, and will not be elaborated here. The measured current is the current generated on the wire in the metal measuring device, and the method of obtaining the measured current is selected by the staff according to the actual situation, and will not be elaborated here.

[0134] Step 501: Control a preset metal measuring device to retract, and match the metal concentration from a preset metal concentration analysis model according to the measured current.

[0135] The metal concentration analysis model refers to a neural network model obtained in advance through sample training. The metal concentration analysis model can match the metal concentration of the metal ion to be measured according to the size of the measurement circuit.

[0136] Step 502: When the metal concentration exceeds a preset safe use range, the preset filter element switching device is controlled to switch the preset adsorption filter element to the outside of the water meter, and an external image of the filter element is obtained.

[0137] The safe use range refers to the normal concentration of metal ions in the water body set in advance. The safe use range is selected by the staff according to the actual situation and will not be elaborated here. The metal concentration exceeding the safe use range means that the metal ion concentration in the water body is too high and the water body cannot be used at this time. The external image refers to the picture of the adsorption filter element obtained after the filter element switching device switches the adsorption filter element to the outside of the water meter. The external image can be obtained through the camera. The method of obtaining the external image is selected by the staff according to the actual situation and will not be elaborated here.

[0138] Step 503: Match a replacement itinerary from a preset replacement itinerary matching model according to the external image.

[0139] A clean filter element refers to a device used to adsorb metal ions in water. An adsorption filter element generally uses an activated carbon filter element or a KDF filter element. The clean filter element is selected by the staff according to the actual situation and will not be described here. The replacement stroke matching model refers to a neural network model obtained through sample training in advance. The replacement stroke matching model can match the replacement stroke of replacing the adsorption filter element on the filter element switching device with a clean filter element through the filter element replacement device.

[0140] Step 504: Control the preset filter element replacement device to replace the adsorption filter element with the clean filter element according to the replacement stroke, and control the preset filter element switching device to switch the clean filter element into the water meter pipeline.

[0141] When clean water stays in a water pipe for a long time, the metal parts in the pipe are easily corroded, causing metal ions to diffuse into the water, which in turn leads to excessively high metal ion concentration in the water. The adsorption filter element is used to adsorb the suspended matter and then replaced with a clean filter element to further reduce the metal ion concentration in the water.

[0142] Reference Figure 6 , the water circulation method comprises the following steps:

[0143] Step 600: Control the preset filter element switching device to switch the preset adsorption filter element to the top of the water meter pipe according to the adsorption time, and obtain the adsorption turbidity in the water meter pipe.

[0144] The filter element switching device switches the adsorption filter element to the top of the water meter pipe so that the water in the water meter pipe passes through the filter element from top to bottom, thereby gradually purifying the water and facilitating the replacement of the filter element and the maintenance of the filter element switching device.

[0145] Step 601: When the adsorption turbidity is lower than a preset adsorption interval, a water flow circulation speed is matched from a preset water flow circulation speed matching model according to the adsorption turbidity.

[0146] The adsorption interval refers to the turbidity interval in which the adsorption filter element achieves the maximum adsorption effect on suspended matter in the water body. The adsorption interval is selected by the staff according to the actual situation and will not be elaborated here. The adsorption turbidity lower than the adsorption interval means that the adsorption filter element cannot achieve the maximum adsorption effect on suspended matter in the water body. The water flow circulation speed matching model refers to a neural network model obtained through sample training in advance. The water flow circulation speed matching model can match the water flow circulation speed required for the adsorption filter element to achieve the maximum adsorption effect on suspended matter in the water body. When the adsorption turbidity is low, a larger water flow circulation speed is used, and when the adsorption turbidity is high, a smaller water flow circulation speed is used, so that the water in the water meter pipe is fully in contact with the filter element.

[0147] Step 602: Match the lifting speed from a preset lifting speed matching model according to the water flow circulation speed.

[0148] The lifting device refers to a device that is set in the water meter pipe corresponding to the filter element and is used to make water flow to the filter element. The lifting device is selected by the staff according to the actual situation and will not be described here. The lifting speed matching model refers to a neural network model obtained through sample training in advance. The lifting speed matching model can match the speed required for the water to flow from the bottom of the water meter pipe to the filter element at the top of the water meter pipe according to the water circulation speed through the lifting device.

[0149] Step 603: Control the lifting device preset at the bottom of the water meter pipe to lift the water flow to the preset adsorption filter element according to the lifting speed.

[0150] When the water meter pipe is long, it is not easy for the adsorption filter element to fully contact all the water bodies. The water flow in the water meter pipe is driven by the lifting device, so that the adsorption filter element can fully adsorb the suspended matter in the water body.

[0151] Reference Figure 7 , the precipitation treatment method comprises the following steps:

[0152] Step 700: When the disinfection device irradiates the water body, a pipe image at the bottom of the water meter pipe is obtained.

[0153] The pipeline image refers to the picture of the bottom of the water meter pipe obtained when the disinfection device irradiates the water body. The pipeline image can be obtained through a camera. The method of obtaining the pipeline image is selected by the staff according to the actual situation and will not be elaborated here.

[0154] Step 701: Determine whether there is impurity precipitation at the bottom of the water meter pipe according to the pipe image from a preset precipitation recognition model.

[0155] The sedimentation recognition model refers to a neural network model obtained through sample training in advance. The sedimentation recognition model can determine whether there is impurity sedimentation at the bottom of the water meter pipe from the pipe image.

[0156] Step 702: When there are impurity deposits at the bottom of the water meter pipe, the thickness of the deposits is matched from a preset deposit thickness matching model according to the pipe image.

[0157] The sediment thickness matching model refers to a neural network model obtained through sample training in advance. The sediment thickness matching model can identify the sediment thickness of the thickest part of the sediment at the bottom of the pipeline from the pipeline image.

[0158] Step 703: Match the pushing speed from a preset pushing speed matching model according to the sediment thickness.

[0159] The push plate device refers to a device installed at the bottom of the pipeline to push the impurities deposited at the bottom of the pipeline. The push plate device is selected by the staff according to the actual situation and will not be described in detail here. The pushing speed matching model refers to a neural network model obtained through sample training in advance. The pushing speed matching model can match the pushing speed of the sedimentation thickness pushed by the push plate device and reduce the surging of the sedimentation during the pushing process. When the sedimentation thickness is large, a lower pushing speed is used, and when the sedimentation thickness is small, a higher pushing speed is used.

[0160] Step 704: Control the push plate device preset at the bottom of the water meter pipe according to the pushing speed to push the sediment into the preset discharge area.

[0161] The discharge area refers to the area in the water meter pipe where the precipitated impurities accumulate so that the precipitated impurities can be discharged uniformly through the drain valve. One end of the discharge area is connected to the water meter pipe, and the other end of the discharge area is connected to the drain valve. The discharge area is selected by the staff according to actual conditions and will not be elaborated here.

[0162] Step 706: Control the isolation valve preset in the water meter to close to isolate the discharge area and the water meter pipeline, and control the preset sewage valve to open and close to discharge the sediment.

[0163] The isolation valve is a valve installed in the water meter to isolate the discharge area from the water meter pipe. The isolation valve is selected by the staff according to the actual situation and will not be described here. The precipitated impurities are pushed into the discharge area through the push plate device, and then the discharge area and the water meter pipe are isolated by the isolation valve, and then the sewage valve is opened to discharge the impurities in the discharge area together with the sewage.
