[0040] Example 2: see Figure 9 , the control box of the sewage treatment device is provided with an intelligent control assembly, and the intelligent control assembly comprises a collection module, an analysis module and an execution module;

[0041] The collection module collects sewage parameter data and flocculant consumption data, and transmits the collected data to the analysis module;

[0042] The analysis module receives the data transmitted by the collection module, pre-processes the data, and then determines whether the addition amount of the flocculant is reasonable according to the pre-processed data. If not, a regulation signal is generated and transmitted to the execution module. The flocculant addition amount is calculated according to the sewage parameter data, and the regulation addition amount is obtained after the flocculant addition amount is calculated with the added amount of the flocculant. The critical value of the flocculant addition amount is calculated, and the single addition amount after the critical value is calculated, a secondary regulation signal is generated, and the secondary regulation signal is transmitted to the execution module.

[0043] The collected data is arranged according to the collection time, and then a plurality of corresponding item data collected at the corresponding time is called to calculate the mean value and standard deviation of the corresponding item data, and the mean value and standard deviation are used to set the fluctuation range of the corresponding item data , the corresponding item data outside the fluctuation range of the corresponding item data is marked as an abnormal value, and after the abnormal value is removed, the mean value of the remaining corresponding item data is calculated, and the calculated mean value is used as the detection data of the corresponding item data at the corresponding time;

[0045] Taking 90% as the determination threshold of turbidity removal rate is based on the double requirements of organic dye wastewater treatment: first, the discharge standard requires that the treated organic dye wastewater should meet the turbidity and color limit value in the “Integrated Wastewater Discharge Standard” (GB8978-1996), and the turbidity removal rate in the flocculation stage directly affects the load of subsequent disinfection and filtration processes. If it is less than ninety percent, the residual suspended particles will adsorb dye molecules and bacteria, resulting in substandard final effluent; second, the experimental verification result shows that when is greater than or equal to ninety percent, more than 80% of the colloidal particles and dye intermediates in the wastewater have been removed by flocculation, and the subsequent disinfectant (such as sodium hypochlorite) can more efficiently act on microorganisms, avoiding the disinfection dead angle caused by particle shielding.

[0046] The unit pollutant flocculant consumption , is the mass concentration of the pollutant, is the volume of the treated wastewater; the flow rate of the wastewater in the pipeline, the radius of the pipeline and the height of the wastewater in the pipeline are obtained, and the cross-sectional area of the pipeline occupied by the wastewater when flowing is calculated , the real-time wastewater flow volume in the pipeline is calculated according to the real-time cross-sectional area data and flow rate ;

The mean of the proportion data of the corresponding component is then calculated. The percentage data of the corresponding components were sorted according to the collection time and compared with the mean. Perform difference calculation, take the absolute value of the calculated difference, and calculate the mean of the differences. If the mean Eighty percent of them are within the range If the value is within the specified range, it is considered normal data fluctuation, and the mean is used. This refers to the percentage data of the corresponding components; based on the percentage data of each component in the wastewater and the real-time wastewater flow volume. Calculate the specific amount of each component in the wastewater per unit time, then calculate the total amount of pollutants that the flocculant can remove. Divide the total amount of pollutants by the volume of wastewater to obtain the amount of pollutants per unit of wastewater. Based on the volume and data of the wastewater to be treated and data The amount of flocculant required for the wastewater to be treated is calculated, and the amount of flocculant already added is subtracted to obtain the adjustment amount. The adjustment amount is then transmitted to the execution module.

[0048] After receiving the adjustment signal, the execution module controls the flocculant addition structure according to the transmitted adjustment amount, which facilitates the adjustment of the subsequent flocculant addition amount.

[0049] Historical data on flocculant consumption per unit of pollutant Calculate the mean and standard deviation, and use these values ​​to set the data fluctuation range. After removing data outside this range, calculate the mean of the remaining data. The calculation is performed, and the difference between the remaining data and the mean of the remaining data is calculated, and the maximum difference is taken. and minimum value Then determine the historical data The fluctuation range is ;

[0050] exist The amount of flocculant added when it is greater than or equal to 90% Record, according to Calculate the total amount added for the corresponding data, and then compare the total amount added with the amount added. Find the minimum value, and use this minimum value as the critical value for flocculant addition; after the flocculant addition reaches the critical value, generate a secondary adjustment signal and transmit it to the execution module; set the adjustment coefficient based on the real-time deviation of the turbidity removal rate. adjustment coefficient The appropriate amount of flocculant to be added each time is determined by dividing the difference between 90% and the real-time turbidity removal rate by 90% and then adding 1. It equals the product of the unit pollutant flocculant consumption, the real-time sewage flow volume, the amount of pollutants in the unit sewage, and the adjustment coefficient, divided by the content of the effective component of the flocculant.

[0051] The value has an upper limit (usually not exceeding 1.5) to prevent [further issues]. Too low (e.g., 60%) leads to If the value is too high (e.g., 1.33), it will lead to excessive addition. In this case, it is necessary to first check for equipment failure (e.g., insufficient mixing, deterioration of flocculant) rather than simply increasing the amount added. The design of this coefficient reflects the concept of "adjustment on demand", which ensures that the insufficient treatment effect can be quickly compensated for, while avoiding the increase in cost caused by blindly increasing the amount.

[0052] After receiving the secondary adjustment signal, the execution module transmits a signal to the flocculant addition structure, adjusting the amount of flocculant added in a single application to... .

[0053] Working Principle: In the use of this invention, wastewater from organic dye production enters the sedimentation tank 2 through the inlet pipe 5. Simultaneously, flocculant is added to the sedimentation tank 2 through the flocculant injection port 7. The first motor 9 starts, driving the stirring blade 10 to rotate. The semi-circular grooves on the stirring blade 10 enhance the stirring effect, ensuring thorough mixing of the wastewater and flocculant, subsequently causing flocculation of pollutants in the water. The settled sludge deposits at the bottom of the sedimentation tank 2 and is pumped into the screw feeder 18 through the suction port 23 and suction pipe by the water pump 24. At this time, the third motor 14 starts, driving the splined shaft 16 to rotate, thereby driving the screw feeder 18 to work. The valve plate 17 remains closed under the action of the spring 20. When the screw feeder 18 starts working, the generated negative pressure will... The spring 20 is compressed and pushes the valve plate 17, opening the valve plate 17 and discharging the flocculated sludge. At the same time, the liquid flows through the filter holes into the base 1. At this time, the second motor 11 starts and drives the two sets of stirring rods 12 to rotate through the cooperation of the transmission belt 13 and the transmission wheel. At the same time, the disinfectant filling port 8 sprays the disinfectant through the nozzle 22 into the housing 15 and the base 1. With the cooperation of the stirring rods 12, the reaction between the disinfectant and the sewage is accelerated, removing odors and bacteria from the sewage. At this time, the radar level gauge 26 monitors the water level in the sewage tank 3. When the water level reaches the set value, it transmits a signal to the solenoid valve 6. The solenoid valve 6 and the water pump 24 are closed to prevent sewage from overflowing from the base 1. Finally, the purified liquid is discharged through the drain pipe 25.
