[0048] In one embodiment, a sewage discharge monitoring system for a sewage outlet into a river is disclosed, such as Figure 1 As shown, the detection system includes:

[0049] A data monitoring module is provided, wherein a plurality of collection and monitoring points are set between the discharge outlet of the sewage treatment equipment and the discharge outlet into the river. The data monitoring module is used to obtain relevant parameter information of the plurality of collection and monitoring points. The relevant parameter information includes the detected ammonia nitrogen concentration value in the sampled sewage and the water temperature, light intensity, and water flow rate of the collection and monitoring points;

[0050] Data analysis module: The data analysis module is used to analyze the relevant parameters obtained to determine whether the sewage treatment is qualified, and generate corresponding discharge instructions according to the judgment results;

[0051] A sewage discharge module, wherein a sewage discharge unit and a return flow unit are provided in the sewage discharge module, and the sewage discharge module discharges sewage into corresponding units according to the generated discharge instruction;

[0052] The sewage secondary treatment module is connected to the return unit and is used for secondary treatment of the returned sewage.

[0053] Through the above technical scheme, in order to more accurately detect whether the discharged ammonia nitrogen sewage meets the discharge standards, the present application sets up multiple collection and monitoring points between the sewage treatment equipment discharge port and the sewage discharge port into the river, so as to obtain the relevant parameter information of each collection and monitoring point, and analyzes the parameter information obtained at each collection and monitoring point through the data analysis module to generate an influencing factor, and adds the influencing factor to the measured ammonia nitrogen concentration value, so that the ammonia nitrogen concentration of the water body can be more accurately obtained, which can reduce the interference of environmental factors and other factors on the monitoring results and make the monitoring results more accurate; at the same time, the sewage with unqualified test results can be returned to the sewage secondary treatment module for secondary treatment, and a suitable treatment residence time and the amount of reagent added can be set for it, so as to facilitate the control of the operating personnel, thereby ensuring the efficiency of sewage treatment.

[0054] As an embodiment of the present invention, the method for the data analysis module to determine whether the sewage treatment is qualified is:

[0055] Obtain the apparent ammonia nitrogen concentration value obtained at each collection monitoring point ;

[0056] So through the formula Obtain the actual ammonia nitrogen concentration value of each collection monitoring point ;

[0064] Through the above technical solution, this embodiment provides a specific method for the data analysis module to determine whether the sewage treatment is qualified. Because when detecting the ammonia nitrogen concentration in sewage, it is easily affected by environmental factors, such as water temperature, water flow rate, light and other factors, resulting in inaccurate results. For example, if the water temperature rises, it will increase the volatilization rate of ammonia nitrogen from the water to the atmosphere, resulting in inaccurate detection. Similarly, if the water flow rate is too large, the ammonia nitrogen concentration will be diluted. Similarly, when the light intensity is large, the photolysis reaction of ammonia nitrogen can be accelerated, causing it to be converted into other nitrogen compounds, or directly volatilized into gaseous ammonia and escape from the water surface, so that the detection results will be erroneous. Therefore, in order to accurately obtain the ammonia nitrogen concentration, the water flow rate of each collection monitoring point is obtained. , water temperature And light intensity Then, through the formula Impact Factor Then, by obtaining the apparent ammonia nitrogen concentration value obtained at each collection monitoring point , through the formula Obtain the actual ammonia nitrogen concentration value of each collection monitoring point ; From the formula, it can be seen that if the water temperature is higher, the light intensity is greater, or the water flow rate is faster, the impact on the ammonia nitrogen concentration in the water will be greater, and the corresponding influencing factor The actual ammonia nitrogen concentration value obtained will be larger than the ammonia nitrogen concentration value measured by the display. In this way, the influencing factors of each collection and monitoring point can be added to the test data to make the obtained data more accurate.

[0065] In the above technical solution, the respective conversion coefficients , as well as The standard evaluation threshold set by the system can be formulated based on historical experience data and experimental data It can be determined based on the corresponding industry evaluation standards, which will not be elaborated here.

[0066] As an embodiment of the present invention, the emission instruction includes a first instruction and a second instruction;

[0067] when When , a first instruction is generated to discharge the sewage into the return unit;

[0068] when When the second instruction is generated, the sewage is discharged into the sewage discharge unit;

[0069] The method for the sewage secondary treatment module to perform secondary treatment on the return sewage is: adjusting the amount of reagent added during the secondary treatment and the sewage retention time accordingly according to the excess value of the ammonia nitrogen concentration in the water body;

[0070] The method for adjusting the amount of drug added is obtained by the following formula:

[0071]

[0072] in, is the amount of drug added, The volume of sewage treated, is the reference value of sewage volume, The maximum amount of drug allowed to be added to the system. is the drug dosage conversion coefficient;

[0073] The method for adjusting the sewage retention time is derived from the following formula:

[0074]

[0075] in, is the dwell time, as well as are their respective time conversion coefficients, is the reference value of the dosage of the drug. For water value, For water Reference value, The best preset value.

[0076] Through the above technical solution, this embodiment provides a method for secondary treatment of returned sewage. Since the detection results are divided into qualified and unqualified, when When , it is considered that the ammonia nitrogen treatment in the sewage treatment is unqualified, and the first instruction is generated to discharge the sewage into the return unit; when When , it is considered that the ammonia nitrogen treatment in the sewage treatment is qualified, and the second instruction is generated to discharge the sewage into the sewage discharge unit for the next step of treatment; and the method for the sewage secondary treatment module to perform secondary treatment on the return sewage is to adjust the amount of reagent added during the secondary treatment and the sewage retention time according to the excess value of the ammonia nitrogen concentration in the water body, so as to better control the efficiency and quality of the secondary treatment. The specific method of adjusting the amount of reagent added is through the formula It can be seen from the formula that when the detected ammonia nitrogen concentration in the water is Compared with the standard water ammonia nitrogen concentration value preset in the system The larger the difference, the more reagents need to be added. Similarly, the larger the volume of sewage to be treated, the more reagents need to be added. However, the amount of reagents added cannot be increased indefinitely. Therefore, a maximum amount of reagents allowed to be added by the system is set to limit the amount of reagents added to ensure the quality of sewage treatment. In this way, the amount of reagents added can be determined based on the volume of sewage to be treated and the amount of ammonia nitrogen concentration exceeding the standard water body value, which can make the feeding more accurate, reduce waste and ensure the efficiency of sewage treatment. The method of adjusting the sewage residence time is through the formula It is concluded that the retention time of sewage treatment is not only related to its ammonia nitrogen content, but also to the added chemicals, water The value of The sewage retention time is obtained. It can be seen from the formula that when the detected ammonia nitrogen concentration in the water body is Compared with the standard water ammonia nitrogen concentration value preset in the system The larger the difference, the The larger the value change, the more time it takes to process. The larger the value, the smaller the amount of added agent, and the corresponding residence time increases accordingly. The larger the value is; in this way, the amount of reagents required for secondary sewage treatment and the sewage retention time can be more accurately obtained according to the relevant factors of the water body and the ammonia nitrogen content, so that the management personnel can make corresponding controls to ensure the quality and efficiency of sewage treatment.

[0077] In the above technical solution, the reference value of sewage volume is , Reference value of dosage of pharmaceutical agent and water bodies Reference value , conversion coefficient , , The maximum amount of medicine allowed to be added by the system can be formulated based on historical experience data and experimental data. , the best preset value It can be determined based on relevant historical experience data in sewage treatment.

[0078] As an implementation mode of the present invention, the data analysis module is also used to judge the quality status of the sewage treatment equipment according to the obtained judgment result. The method for the data analysis module to judge the quality status of the sewage treatment equipment is:

[0079] Get the total number of emission instructions generated within a preset period , and obtain the water body ammonia nitrogen concentration value obtained each time a discharge instruction is generated ;

[0080] By formula Obtain the quality condition coefficient of the sewage treatment equipment ;

[0081] The quality condition coefficient The threshold coefficient of the standard quality status preset by the system To compare:

[0082] when When , it is judged that the quality of the sewage treatment equipment is poor;

[0083] in, ,and , is the number of times that the ammonia nitrogen concentration in the water body is greater than the average ammonia nitrogen concentration in the water body among all the times. The number of times the first instruction is generated among all the times.

[0084] Through the above technical solution, this embodiment provides a specific method for the data analysis module to judge the quality of the sewage treatment equipment according to the obtained judgment results. First, a preset period is set, and at least ten sewage monitoring and treatment are performed during the preset period. The discharge instruction during each sewage monitoring and treatment, and the ammonia nitrogen concentration value of the water body obtained each time the discharge instruction is generated are obtained. , through the formula Obtain the quality condition coefficient of the sewage treatment equipment ,formula It indicates the number of times the ammonia nitrogen concentration in the water body is greater than the average ammonia nitrogen concentration in the water body among all the sewage monitoring and treatment times. The formula is It indicates the number of times the first instruction is generated in all sewage monitoring and treatment times, that is, the number of times the treatment fails. When the formula The larger the value, the worse the treatment effect of the sewage treatment equipment, and the formula It shows the fluctuation of the ammonia nitrogen concentration value of the water body monitored each time within the preset period. It can be seen that the larger the value, the greater the fluctuation of each treatment, which means that the quality of the sewage treatment equipment is less problematic and the greater the possibility of problems. Therefore, combined with the formula Comprehensive analysis to obtain the quality status coefficient of sewage treatment equipment , and the quality condition coefficient obtained The threshold coefficient of the standard quality status preset by the system For comparison, the system preset standard quality status threshold coefficient It can be obtained based on empirical data. When the sewage treatment equipment is in poor condition, it can be considered that the treatment effect of the sewage treatment equipment is poor, and the quality of the sewage treatment equipment is judged to be poor. At this time, a corresponding early warning signal can be generated to remind the maintenance management personnel to promptly handle the sewage treatment equipment. Through this operation, it is possible to analyze whether the sewage treatment equipment has quality abnormalities based on the proportion of ammonia nitrogen concentration in the water body exceeding the standard value and the average value over a period of time combined with the fluctuation of ammonia nitrogen concentration in the water body, so as to promptly repair the abnormal equipment and ensure the efficiency of sewage treatment.

[0085] The present invention sets a plurality of collection and monitoring points between the discharge port of the sewage treatment equipment and the sewage discharge port into the river, thereby obtaining relevant parameter information of each collection and monitoring point, and analyzes the parameter information obtained at each collection and monitoring point through a data analysis module to generate an influencing factor, and adds the influencing factor to the measured ammonia nitrogen concentration value, so that the actual ammonia nitrogen concentration of the water body can be obtained more accurately, which can reduce the interference of environmental factors and other factors on the monitoring results and make the monitoring results more accurate; the present invention can return the sewage with unqualified test results to the sewage secondary treatment module for secondary treatment, and set a suitable treatment residence time and agent addition amount for it according to the obtained ammonia nitrogen concentration value, so as to facilitate the control of the operating personnel, thereby ensuring the efficiency and quality of sewage treatment; the present invention can analyze whether the sewage treatment equipment has quality abnormalities according to the proportion of the ammonia nitrogen concentration of the water body exceeding the standard value and the average value within a period of time combined with the fluctuation of the ammonia nitrogen concentration value of the water body, so as to timely repair the abnormal equipment and ensure the sewage treatment efficiency.
