DETAILED DESCRIPTION

[0021] The present application will be further described in detail below with reference to the accompanying drawings and embodiments.

[0022] Referring to Figure 1 , the present application discloses a water treatment automatic control method, comprising the following steps: S10: Collecting original water detection parameters and reference detection parameters.

[0023] The original water detection parameters refer to the turbidity, water temperature, and ph value of the original water that needs to be treated, and the turbidity, water temperature, and ph value detected by the sensors preset at the water inlet end of the grid flocculation tank are used as the original water detection parameters.

[0024] The benchmark detection parameter refers to an operation index for treating raw water with different water quality parameters. The benchmark detection parameter can be pre-input by an operator. In this embodiment, the benchmark detection parameter includes different turbidity ranges, and the turbidity ranges are 100 NTU to 500 NTU.

[0025] S11: obtaining the flocculation dosage by the raw water detection parameter.

[0026] The flocculation dosage refers to the amount of flocculant added for purifying the raw water in the grid flocculation tank. The flocculation dosage is matched from the preset clean water control table by the raw water detection parameter.

[0027] The clean water control table stores the flocculation dosages corresponding to different raw water detection parameters. The higher the turbidity in the raw water detection parameter, the lower the water temperature, and the farther the deviation from the optimal pH value, the greater the required flocculation dosage. The parameters in the clean water control table are set by the person skilled in the art according to actual conditions in advance, and will not be described here.

[0028] S12: retrieving the detection water turbidity from the raw water detection parameter.

[0029] The detection water turbidity refers to the turbidity parameter of the raw water that needs to be treated when entering the grid flocculation tank. The turbidity parameter is retrieved from the raw water detection parameter as the detection water turbidity.

[0030] S13: retrieving the benchmark turbidity range from the benchmark detection parameter.

[0031] The benchmark turbidity range refers to the range of stirring speed matching set for different turbidity of raw water. The benchmark turbidity range is retrieved from the benchmark detection parameter. In this embodiment, the benchmark turbidity range is the turbidity range in S10.

[0032] S14: obtaining the detection speed according to the falling situation of the detection water turbidity and the benchmark turbidity range.

[0033] The stirring device is a variable frequency stirring motor. The detection speed refers to the running speed of the stirring device in the grid flocculation tank. The falling situation of the detection water turbidity and the benchmark turbidity range is analyzed. When the detection water turbidity is less than 100 NTU, the detection speed is set to 300 r / min. When the detection water turbidity is greater than or equal to 100 NTU and less than 500 NTU, the detection speed is set to 450 r / min. When the detection water turbidity is greater than 500 NTU, the speed is set to 600 r / min, to facilitate subsequent enhancement of the flocculation effect of the grid flocculation tank.

[0034] S15: adding the flocculant in the preset grid flocculation tank with the flocculation dosage, and synchronously controlling the stirring device preset in the grid flocculation tank to run at the detection speed.

[0035] The flocculant is added by a metering pump preset in the grid flocculation tank, and a stirring device is controlled synchronously to detect the rotating speed.

[0036] S16: Collect the turbidity at the outlet of the flocculation tank.

[0037] The turbidity at the outlet of the flocculation tank refers to the turbidity parameter of the water flowing out from the outlet of the grid flocculation tank after the raw water is treated by the grid flocculation tank, which is obtained by real-time detection by a turbidity sensor preset at the outlet of the grid flocculation tank.

[0038] S17: Update the flocculation dosage based on the turbidity at the outlet of the flocculation tank.

[0039] The new flocculation dosage is matched from the clean water control table based on the turbidity at the outlet of the flocculation tank. The clean water control table also stores the new flocculation dosage corresponding to different turbidities at the outlet of the flocculation tank. In the case where the original flocculation dosage remains unchanged, the higher the turbidity at the outlet of the flocculation tank, the greater the coefficient value used to correct the original flocculation dosage, and the greater the new flocculation dosage calculated. Details are not described herein.

[0040] Reference Figure 2 The method for adding the flocculant into the grid flocculation tank after the flocculation dosage is preset includes: S20: Collect the marked water inflow parameter, the marked sedimentation time, and the marked water outflow parameter of the inclined tube sedimentation tank.

[0041] The marked water inflow parameter refers to the water quality parameter at the water inflow end of the inclined tube sedimentation tank, which is detected by various sensors preset at the water inflow end of the inclined tube sedimentation tank, such as turbidity, water temperature, and pH value. In this embodiment, the water inflow end of the inclined tube sedimentation tank is connected to the water outflow end of the grid flocculation tank, that is, the turbidity in the marked water inflow parameter is the turbidity at the outlet of the flocculation tank.

[0042] The marked sedimentation time refers to the actual residence time of the water flow in the inclined tube from the water inflow end of the inclined tube sedimentation tank to the water outflow end of the inclined tube sedimentation tank. The marked sedimentation time is obtained by calculating the quotient of the effective volume of the inclined tube sedimentation tank and the actual water inflow flow rate.

[0043] The marked water outflow parameter refers to the water quality parameter at the water outflow end of the inclined tube sedimentation tank after the water is deposited in the inclined tube sedimentation tank, which is detected by various sensors preset at the water outflow end of the inclined tube sedimentation tank, such as turbidity, water temperature, and pH value.

[0044] S21: Obtain the sludge discharge period and the sludge discharge duration by the marked water inflow parameter, the marked sedimentation time, and the marked water outflow parameter.

[0045] The sludge discharge period refers to the time interval period of multiple sludge discharge operations of the inclined tube sedimentation tank, and the sludge discharge duration refers to the time length value of a single sludge discharge operation of the inclined tube sedimentation tank. The sludge discharge period and the sludge discharge duration are matched from the clean water control table by marking the influent parameters, marking the sedimentation time, and marking the effluent parameters.

[0046] The sludge discharge period and the sludge discharge duration corresponding to different marked influent parameters, marked sedimentation time, and marked effluent parameters are also stored in the clean water control table. The larger the marked influent parameters, the smaller the marked sedimentation time, and the larger the marked effluent parameters (the turbidity becomes larger due to sludge accumulation), the smaller the sludge discharge period, and the larger the sludge discharge duration. Details are not repeated here.

[0047] In this embodiment, the sludge discharge period can be adjusted in the range of 8 to 24 hours.

[0048] S22: Collect the sludge height.

[0049] The sludge height refers to the vertical height of the sludge layer deposited at the bottom of the inclined tube sedimentation tank, which is obtained by real-time detection by a sludge interface instrument pre-set at the bottom of the inclined tube sedimentation tank.

[0050] S23: According to the exceeding situation of the sludge height and the pre-set reference abnormal height, the pre-set sludge discharge valve is selected and controlled to operate with the sludge discharge period and the sludge discharge duration and update the sludge height, or the sludge discharge valve is closed.

[0051] The reference abnormal height is a parameter set by the technician to determine whether the inclined tube needs to be discharged. In this embodiment, the reference abnormal height is 1 m. By analyzing the exceeding situation of the sludge height and the reference abnormal height, when the sludge height exceeds the reference abnormal height, the pre-set sludge discharge valve on the inclined tube sedimentation tank is controlled to be opened with the sludge discharge period and the sludge discharge duration, and the sludge height is continuously re-acquired.

[0052] When the sludge height does not exceed the reference abnormal height, if the sludge discharge valve is in the open state, the sludge discharge valve is closed, and if the sludge discharge valve is in the closed state, no adjustment is made.

[0053] S24: Collect the sludge discharge times of the sludge discharge valve.

[0054] The sludge discharge times refer to the number of times of sludge discharge of the sludge discharge valve, and the number of times of opening and closing of the sludge discharge valve within the sludge discharge period is recorded as the sludge discharge times.

[0055] S25: When the sludge discharge times are greater than the pre-set reference times, the pre-set treatment method is used to treat the blockage of the inclined tube.

[0056] The treatment method refers to a method for treating the blockage of the inclined tube or cleaning the adhesion of the inner wall of the inclined tube.

[0057] The reference number of times is a parameter set by a technician for judging whether the inclined pipe is blocked. In this embodiment, the reference number of times is set to 3. When the number of times of discharging sludge is greater than the reference number of times, it indicates that the inclined pipe is blocked, and then the processing method is used to process the blockage of the inclined pipe.

[0058] With reference to Figure 3 Further comprising: S30: Collecting the target water turbidity of the filter tank, the inlet side pressure and the outlet side pressure, and the target filtration time length.

[0059] The target water turbidity refers to the water turbidity of the outlet after the V-type filter tank filtration, which is collected in real time by the turbidity sensor preset at the outlet of the V-type filter tank.

[0060] The inlet side pressure refers to the static pressure of the water body at the inlet end of the V-type filter tank, which is collected in real time by the pressure sensor preset at the inlet side pipeline of the V-type filter tank. The outlet side pressure refers to the static pressure of the water body at the outlet end of the V-type filter tank, which is collected in real time by the pressure sensor preset at the outlet side pipeline of the V-type filter tank.

[0061] The target filtration time length refers to the time length value of the V-type filter tank from the end of backwashing to the recovery of the filtration state. The time is counted from the time point when the V-type filter tank recovers to the filtration state after the end of backwashing, and the counting result is taken as the target filtration time length.

[0062] S31: Calculating the filter layer head loss based on the inlet side pressure and the outlet side pressure.

[0063] The filter layer head loss refers to the energy loss caused by the blockage of filter material and the friction of impurities when the water passes through the filter material layer of the V-type filter tank. The filter layer head loss is calculated by (inlet side pressure-outlet side pressure) x 10.2=filter layer head loss. 10.2 refers to 1 MPa≈10.2 m water column.

[0064] S32: Calculating the turbidity deviation value, the head deviation value, and the time length deviation value based on the difference between the target water turbidity and the preset reference water turbidity, the difference between the filter layer head loss and the preset reference head loss, and the difference between the target filtration time length and the preset reference filtration time length.

[0065] The reference water turbidity is a turbidity threshold value set by a technician to trigger the backwashing of the V-type filter tank. The reference head loss is a head loss threshold value set by a technician to trigger the backwashing of the V-type filter tank. The reference filtration time length is a filtration time length threshold value set by a technician to trigger the backwashing of the V-type filter tank. In this embodiment, the reference water turbidity is set to 0.75 NTU, the reference head loss is set to 1.25 m, and the reference filtration time length is set to 48 hours.

[0066] Turbidity deviation refers to the deviation between the target water turbidity and the reference water turbidity; head deviation refers to the deviation between the filter head loss and the reference head loss; and duration deviation refers to the deviation between the target filtration time and the reference filtration time.

[0067] The analysis examines the deviations of the target water turbidity from the preset reference water turbidity, the filter bed head loss from the preset reference head loss, and the target filtration time from the preset reference filtration time. When any two of the following three conditions are met—"target water turbidity exceeds reference water turbidity," "filter bed head loss exceeds reference head loss," and "target filtration time exceeds reference filtration time"—backwashing of the V-type filter is triggered. Therefore, the difference between the target water turbidity and the reference water turbidity is calculated as the turbidity deviation value; the difference between the filter bed head loss and the reference head loss is calculated as the head deviation value; and the difference between the target filtration time and the preset reference filtration time is calculated as the duration deviation value.

[0068] S33: The blowing power, secondary air-water combined power and tertiary flushing power are obtained by using turbidity deviation value, water head deviation value and duration deviation value, and the primary output is performed with preset primary execution duration and blowing power, and the target drainage turbidity is collected.

[0069] In this embodiment, the backwashing process of the V-type filter is as follows: 1. The filter layer of the V-type filter is scrubbed with air; 2. The filter layer of the V-type filter is flushed with a combination of air and water flow; 3. The filter layer of the V-type filter is flushed with water flow.

[0070] The first-level execution time is the time set by the technicians for wiping the filter layer of the V-type filter bed with air.

[0071] Air blowing power refers to the power required to scrub the filter layer of the V-type filter bed with air. The air blowing power is matched from the water purification comparison table by turbidity deviation value, water head deviation value, and time deviation value.

[0072] The combined power of air and water in the secondary stage refers to the power of the airflow and the power of the waterflow output when the filter layer of the V-type filter is flushed by the combined air and water flow. The combined power of air and water in the secondary stage is matched from the water purification comparison table by the turbidity deviation value, water head deviation value, and time deviation value.

[0073] The three-stage flushing power refers to the power of the water flow output when flushing the filter layer of the V-shaped filter. The three-stage flushing power is matched from the water purification comparison table by the turbidity deviation value, water head deviation value, and time deviation value.

[0074] The water purification control table also stores different turbidity deviation values, water head deviation values, and time length deviation values corresponding to the blowing power and water flow output power. The greater the turbidity deviation value, the greater the water head deviation value, and the greater the time length deviation value, the greater the blowing power, the secondary air-water combined power, and the tertiary flushing water power. This will not be described here.

[0075] The target drainage turbidity refers to the turbidity of the water discharged during the backwashing process of the V-type filter. The parameter detected by the turbidity sensor preset at the drainage of the V-type filter is used as the target drainage turbidity.

[0076] S34: According to the exceeding condition of the target drainage turbidity and the preset reference drainage turbidity, the secondary execution time length and the secondary air-water combined power are used for secondary output.

[0077] The reference drainage turbidity is a parameter set by the technician to determine whether to stop the backwashing of the V-type filter. The secondary execution time length is the time length value set by the technician to flush the filter layer of the V-type filter by combining air and water flow. In this embodiment, the reference drainage turbidity is set to 1.25 NTU.

[0078] By analyzing the exceeding condition of the target drainage turbidity and the reference drainage turbidity, when the target drainage turbidity does not exceed the reference drainage turbidity, the backwashing process of the V-type filter is ended.

[0079] When the target drainage turbidity exceeds the reference drainage turbidity, the secondary execution time length and the secondary air-water combined power are used for secondary output to continue the backwashing process of the V-type filter.

[0080] S35: Update the target drainage turbidity, and according to the exceeding condition of the target drainage turbidity and the preset reference drainage turbidity, the tertiary execution time length and the tertiary flushing water power are used for tertiary output.

[0081] The tertiary execution time length is the time length value set by the technician to flush the filter layer of the V-type filter by water flow.

[0082] The target drainage turbidity is continuously re-acquired, and by analyzing the exceeding condition of the target drainage turbidity and the reference drainage turbidity, when the target drainage turbidity does not exceed the reference drainage turbidity, the backwashing process of the V-type filter is ended.

[0083] When the target drainage turbidity exceeds the reference drainage turbidity, the tertiary execution time length and the tertiary flushing water power are used for tertiary output to continue the backwashing process of the V-type filter.

[0084] Reference Figure 4 Also includes: S40: Update the detected water turbidity.

[0085] Re-acquire the raw water detection parameters to obtain a new detection water turbidity.

[0086] S41: Calculate the difference between the detection water turbidity before and after the update as the turbidity change value.

[0087] The turbidity change value refers to the deviation value between the detection water turbidity before and after the update, and the difference between the detection water turbidity before and after the update is calculated as the turbidity change value.

[0088] S42: According to the turbidity change value and the reference change value, a correction value is obtained by the exceeding condition of the turbidity change value and the preset reference change value.

[0089] The reference change value is a threshold value set by the technician to judge whether the raw water turbidity fluctuation needs to adjust the process parameters. The correction value refers to the coefficient value for correcting the flocculation dosage and detection speed. By analyzing the exceeding condition of the turbidity change value and the reference change value, when the turbidity change value exceeds the reference change value, it means that the process parameters need to be adjusted, and then the difference between the turbidity change value and the reference change value is calculated as the change deviation value, and the correction value is matched from the clean water control table according to the change deviation value.

[0090] The clean water control table also stores the correction values corresponding to different change deviation values. The larger the change deviation value, the larger the correction value, which will not be described here.

[0091] S43: Update the flocculation dosage and detection speed according to the correction value.

[0092] The new flocculation dosage is obtained by calculating the product of the flocculation dosage and the corresponding correction value. The new detection speed is obtained by calculating the product of the detection speed and the corresponding correction value.

[0093] S44: Based on the correction value, a washing cycle is obtained, and the filter tank is controlled to backwash according to the washing cycle.

[0094] The washing cycle refers to the cycle of the V-type filter tank for backwashing. The washing cycle is matched from the clean water control table by the correction value, and the filter tank is controlled to backwash according to the washing cycle.

[0095] The clean water control table also stores the washing cycles corresponding to different correction values. The larger the correction value, the smaller the washing cycle. The washing cycle still has a threshold range, which is set by the technician in advance, and will not be described here.

[0096] The preset processing method includes: S50: Collect the detection flow rate of each section of the inclined pipe.

[0097] The detection flow rate refers to the flow rate of water in different sections (such as the water inlet section, the middle section, and the water outlet section) of the inclined tube sedimentation tank. The ultrasonic flow rate sensor pre-set in different sections (such as the water inlet section, the middle section, and the water outlet section) of the inclined tube is used to collect the flow rate of each section in real time as the detection flow rate.

[0098] S51: obtaining the detection pressure difference by marking the water inlet parameter and the water outlet parameter.

[0099] The detection pressure difference refers to the deviation between the pressure at the water inlet end of the inclined tube and the pressure at the water outlet end. The pressure at the water inlet end of the inclined tube is retrieved from the marked water inlet parameter, and the pressure at the water outlet end is retrieved from the marked water outlet parameter. The difference between the pressure at the water inlet end and the pressure at the water outlet end is calculated as the detection pressure difference.

[0100] S52: retrieving the marked water outlet turbidity from the marked water outlet parameter.

[0101] The marked water outlet turbidity refers to the turbidity of water at the water outlet end of the inclined tube sedimentation tank. The marked water outlet turbidity is retrieved from the marked water outlet parameter.

[0102] S53: obtaining the clogging position and the clogging parameter by the detection flow rate, the detection pressure difference, and the marked water outlet turbidity.

[0103] The clogging position refers to the position of the specific inclined tube section where clogging occurs in the inclined tube sedimentation tank. The position of the abnormal detection flow rate is obtained as the clogging position by detecting the exceeding of the detection flow rate and the pre-set reference flow rate. The reference flow rate is the normal flow rate when there is no flocculation and sediment adhesion on the inner wall of the inclined tube.

[0104] The clogging parameter refers to the volume and other parameters of the flocculation or sediment at the clogging position. The clogging parameter is matched from the clean water control table by the detection flow rate, the detection pressure difference, and the marked water outlet turbidity.

[0105] The clean water control table also stores different detection flow rates, detection pressure differences, and marked water outlet turbidities. The corresponding clogging parameters are obtained by analyzing and calculating the corresponding relationships of the along-path resistance formula of fluid mechanics, Stokes' law, and the turbidity and the concentration of suspended solids in water. The method for calculating the clogging parameter in the clean water control table is known to those skilled in the art, and is not described here.

[0106] S54: obtaining the water flow pressure based on the clogging parameter.

[0107] The water flow pressure refers to the pressure generated by the water flow in the inclined tube on the clogging material. The water flow pressure is obtained by analyzing and calculating the clogging parameter. The analysis and calculation method of the water flow pressure is known to those skilled in the art, and is not described here.

[0108] S55: Obtain the detection frequency and the alternating power by the blockage parameter and the water flow pressure, and control the magnetic attraction device preset on the outer wall of the inclined pipe to guide the fine wire preset on the inner wall of the inclined pipe to run at the detection frequency and the alternating power at the blockage position.

[0109] The magnetic attraction device refers to an electromagnet installed on the outer wall of the inclined pipe, and the magnetic attraction device can move along the circumference and the radius of the inclined pipe. The fine wire device refers to a wire reel device provided with a fine wire, which is arranged on the inclined pipe sedimentation tank, and the fine wire of the fine wire device is arranged in the inclined pipe. The fine wire device can move along the water inlet of the inclined pipe, so that one end of the fine wire still abuts against the water inlet of the inclined pipe. The material of the fine wire is a composite material, and the core of the fine wire can be attracted by the magnetic field of the magnetic attraction device.

[0110] The alternating power refers to the power of the magnetic attraction device for alternating change, and the detection frequency refers to the frequency of the magnetic attraction device for alternating change at the alternating power. The detection frequency and the alternating power are matched from a preset cleaning reference table according to the blockage parameter and the water flow pressure. And control the magnetic attraction device to guide the fine wire to run at the detection frequency and the alternating power at the blockage position to generate an alternating magnetic field, drive the fine wire to vibrate at a high frequency along the inner wall of the inclined pipe, and loosen the blockage in the inclined pipe.

[0111] The cleaning reference table stores different detection frequencies and alternating powers corresponding to different blockage parameters and water flow pressures. The greater the blockage parameter and the smaller the water flow pressure, the greater the detection frequency and the alternating power. The parameters in the cleaning reference table are set by the skilled person according to the actual situation in advance, which will not be described here.

[0112] Further comprising: S60: Based on the exceeding condition of the detection flow rate and the preset reference flow rate, collect image detection information in the inclined pipe.

[0113] The reference pressure difference is the normal pressure difference value when there is no flocculation and sediment adhesion on the inner wall of the inclined pipe.

[0114] The image detection information refers to the image in the inclined pipe. By analyzing the exceeding condition of the detection flow rate and the reference flow rate, when the detection flow rate does not exceed the reference flow rate, it indicates that there is flocculation and sediment adhesion on the inner wall of the inclined pipe, the cross-sectional area of the water flow through the inclined pipe becomes smaller, the flow rate of the inclined pipe becomes smaller, and the flow rate of the inclined pipe also becomes smaller. Therefore, the image of the sensor position of the detection flow rate exceeding the reference flow rate is taken by the miniature camera as the image detection information.

[0115] S61: Obtain the adhesion position and the adhesion parameter by the image detection information.

[0116] The adhesion position refers to the position where the flocculation and the sediment actually adhere to the inner wall of the inclined pipe, which is identified from the image detection information.

[0117] The adhesion parameter refers to a size parameter of the actual adhesion of the floc and the precipitate to the inner wall of the inclined pipe, and the adhesion parameter is identified from the image detection information.

[0118] S62: Obtain the length of the inclined line by combining the adhesion position and the preset inclined pipe specification.

[0119] The inclined pipe specification is a shape and size specification of the inclined pipe set by the technician, and the length of the inclined line refers to a length value of the inclined line in the inclined pipe. When the thread device is located at the position of the inclined pipe inlet corresponding to the straight line of the adhesion position, the thread is drooping in the inclined pipe due to gravity. The length of the inclined line corresponding to different adhesion positions is different when the size of the inclined pipe inlet is unchanged. Therefore, the length of the inclined line is obtained by combining the adhesion position and the inclined pipe specification using the Pythagorean theorem. The analysis method of the length of the inclined line is well known to those skilled in the art, and will not be described here.

[0120] S63: Obtain the reference force and the cleaning direction based on the adhesion parameter.

[0121] The cleaning direction refers to the direction of the circumferential rotation of the thread along the inner wall of the inclined pipe from the adhesion position. The direction of the circumferential rotation corresponding to the smaller distance between the adhesion position and the bottom of the inclined pipe inlet is taken as the cleaning direction. For example, when the inclined pipe inlet is circular, the bottom of the inclined pipe inlet is set as the position of the clock 6 o'clock. When the adhesion position is set as the position of 1 o'clock, the cleaning direction is clockwise. When the adhesion position is set as the position of 9 o'clock, the cleaning direction is counterclockwise.

[0122] S64: Obtain the inclined pipe flow rate range by the raw water detection parameter.

[0123] The inclined pipe flow rate range refers to a normal speed interval of the water flow in the inclined pipe during the raw water purification treatment. The inclined pipe flow rate range is matched from the clean water control table by the raw water detection parameter. The clean water control table also stores the inclined pipe flow rate range corresponding to different raw water detection parameters, which will not be described here.

[0124] S65: Obtain the detection force according to the inclined pipe flow rate range.

[0125] The detection force refers to the force of the water flow in the inclined pipe to drive the thread parallel to the axis of the inclined pipe. The impact force of the water flow on the thread is calculated as the detection force by the inclined pipe flow rate range. The calculation method of the detection force is well known to those skilled in the art, and will not be described here.

[0126] S66: Calculate the difference between the detection force and the preset reference force as the force deviation value.

[0127] The reference force is the force of the water flow set by the technician to make the thread parallel to the inclined pipe axis. The force deviation value refers to the deviation value between the detected force and the reference force, which is obtained by calculating the difference between the detected force and the reference force.

[0128] S67: According to the force deviation value, the adhesion parameter and the thread inclination length, the magnetic attraction power is obtained, the thread device is controlled to run at the adhesion position, the magnetic attraction device is controlled to run at the cleaning direction with the magnetic attraction power, and the thread device is synchronized with the magnetic attraction device to run at the cleaning direction.

[0129] The magnetic attraction power refers to the power required for the magnetic attraction device to attract the thread to be parallel to the inclined pipe axis at the adhesion position, and to fix the thread to clean the adhering objects on the inner wall of the inclined pipe.

[0130] When the thread device is controlled to run at the adhesion position, the thread gradually inclines in the inclined pipe. The force deviation value is used to obtain the inclination angle of the thread under the impact of the water flow in the inclined pipe, and the thread inclination length is updated according to the inclination angle. The magnetic attraction power corresponding to the magnetic attraction force is obtained by analyzing the thread inclination length and the gravity of the thread to move the thread towards the inner wall of the adhesion position. When the thread moves to the adhesion position, the magnetic attraction device attracts the thread with the magnetic attraction power corresponding to the force of cleaning the adhering objects, and the magnetic attraction device and the thread device are controlled to move circumferentially at the cleaning direction so that the thread can scrape off the adhering objects on the inner wall of the inclined pipe.

[0131] The verification method of the adhesion parameter comprises: S70: The flocculation parameters are obtained by the raw water detection parameters and the flocculation dosage.

[0132] In this embodiment, the image detection information is only the shooting of the inclined pipe water inlet towards the sensor position, and there is a blind area, so the adhesion parameter needs to be verified.

[0133] The flocculation parameter refers to the core physical characteristic parameter of the flocculation generated after the raw water is treated by the grid flocculation tank. The flocculation parameter is matched from the clean water control table by the raw water detection parameter and the flocculation dosage.

[0134] The clean water control table stores different flocculation parameters corresponding to the raw water detection parameters and the flocculation dosage. In the case of optimal flocculation dosage, the higher the turbidity in the raw water detection parameter, the lower the water temperature, the larger the flocculation particle size in the flocculation parameter, the farther the ph value deviates from the optimal range, and the lower the flocculation strength in the flocculation parameter. This will not be repeated here.

[0136] The flow parameter refers to a coefficient value corresponding to a motion characteristic of the water flow driving the floc to flow in the inclined pipe. The flow parameter includes a floc settling velocity, a floc flow velocity, and a floc transverse diffusion coefficient, etc. The flow parameter is matched from the cleaning reference table according to the floc parameter and the inclined pipe flow velocity range.

[0137] The cleaning reference table also stores flow parameters corresponding to different floc parameters and inclined pipe flow velocity ranges. The larger the floc parameter, the smaller the inclined pipe flow velocity range, and the smaller the flow parameter. Details are not repeated here.

[0142] The cleaning reference table also stores resistance parameters corresponding to different floc parameters and inclined pipe shapes. In the case of the same inclined pipe shape, the larger the floc parameter, the greater the resistance generated by the inclined pipe to the floc parameter. Details are not repeated here.

[0143] S74: update the adhesion parameter by comparing the resistance parameter and the flow parameter.

[0144] The new adhesion parameter is obtained by calculating the product of the adhesion parameter and the ratio of the resistance parameter to the flow parameter.

[0148] The floc average parameter refers to an average floc parameter of the floc passing through the inclined pipe. The floc average parameter is matched from the cleaning reference table according to the floc parameter and the inclined pipe flow velocity range.

[0149] The cleaning reference table also stores floc average parameters corresponding to different floc parameters and inclined pipe flow velocity ranges. The larger the floc parameter, the greater the inclined pipe flow velocity range, and the more flocs passing through per unit time, and the larger the floc average parameter. Details are not repeated here.

[0150] S82: Calculate the adsorption distance by the adhesion position and the inclined length of the fine line.

[0151] The adsorption distance refers to the distance between the adhesion position and the fine line in the direction of the cross section of the inclined pipe. The adsorption distance is calculated by the adhesion position and the inclined length of the fine line and the inclined angle corresponding to the inclined length of the fine line in S67 using the Pythagorean theorem.

[0152] S83: Update the floc average parameter based on the adsorption distance.

[0153] The cross section between the adhesion position and the fine line is updated by the adsorption distance. The ratio is calculated between the cross section and the cross section in the specification of the inclined pipe. The new floc average parameter is obtained by calculating the ratio and the floc average parameter.

[0154] S84: Obtain the blocking coefficient according to the floc average parameter and the adhesion parameter.

[0155] The blocking coefficient refers to the coefficient value of the floc blocking the magnetic field distribution of the magnetic attraction device. The blocking coefficient is matched from the cleaning control table by the floc average parameter and the adhesion parameter.

[0156] The cleaning control table stores different blocking coefficients corresponding to different floc average parameters and adhesion parameters. The larger the floc average parameter and the adhesion parameter, the larger the blocking coefficient. Details are not described here.

[0157] S85: Update the magnetic attraction power by the blocking coefficient.

[0158] The product of the magnetic attraction power and the blocking coefficient is calculated to obtain the new magnetic attraction power.

[0159] The calibration method of the magnetic attraction power further comprises: S90: Retrieve the marked effluent temperature from the marked effluent parameter.

[0160] The marked effluent temperature refers to the temperature of the water at the effluent end after precipitation in the inclined pipe sedimentation tank. The marked effluent temperature is retrieved from the marked effluent parameter.

The temperature deviation value is calculated by calculating the difference between the marked effluent temperature and the reference temperature value.

[0163] S92: Update the floc average parameter by the temperature deviation value.

[0164] The less the number of passing flocs in unit time is, the smaller the average parameter of flocs is, by the temperature deviation value to update the adhesion of water flow, so by matching the temperature deviation value from the cleaning control table to the new average parameter of flocs, no more details are given here.

[0165] S93: update the magnetic attraction power by the temperature deviation value and the updated average parameter of flocs.

[0166] Referring to S84, the new blocking coefficient is obtained by the new average parameter of flocs, the temperature blocking coefficient is obtained by analyzing the temperature deviation value, and the product of the magnetic attraction power, the new blocking coefficient and the temperature blocking coefficient is calculated as the new magnetic attraction power.
