[0026] The application will be further described in detail below in combination with the following embodiments.

[0027] Referring to Figure 1 A sewage treatment remote scheduling control method, the method comprising the following steps:

[0028] Step S1, according to the sewage treatment sequence, the last sewage treatment link is marked as the first treatment link, and the next sewage treatment link is marked as the second treatment link. The water quality of the sewage to be purified is detected to schedule the parameters of the first treatment link. If the water quality parameters of the sewage treated by the first treatment link are the same as the predicted water quality parameters, the first treatment scheme is developed.

[0029] Step S2, if the water quality parameters after the first sewage treatment of the processing link one are different from the predicted water quality parameters, auxiliary sampling points are selected, the pretreatment water quality parameters after the first sewage treatment of the processing link one are detected again according to the auxiliary sampling, the step one energy consumption value of the processing link one for the second parameter scheduling control is counted according to the pretreatment water quality parameters.

[0030] Step S3, the step two energy consumption value of the processing link two for the sewage treatment is counted according to the pretreatment water quality parameters, and the processing scheme two and the processing scheme three are formulated according to the to-be-measured energy consumption ratio between the step one energy consumption value and the step two energy consumption value.

[0031] Specifically, by scheduling the sewage treatment parameters of the processing link one, the water quality characteristic data of the sewage treated by the processing link one is detected at two main sampling points, and is compared with the predicted water quality parameters under ideal sewage treatment conditions. If they are the same, the sewage treatment of the processing link two is carried out in the normal processing step sequence, and the parameter scheduling of the processing link two is controlled according to the predicted water quality parameters. If they are not the same, there is a great possibility of detection error, so other sampling points are selected for water quality characteristic data detection, so as to reduce the large error caused by the subsequent sewage treatment parameter scheduling according to the detected water quality characteristic data. The energy consumption value of the processing link one for the second parameter control according to the pretreatment water quality parameters is judged according to the pretreatment water quality parameters comprehensively detected by the selected other sampling points, and the energy consumption value of the processing link two for the sewage treatment according to the pretreatment water quality parameters is compared to obtain the to-be-measured energy consumption ratio. According to the numerical relationship between the to-be-measured energy consumption ratio and the preset judgment energy consumption ratio threshold, two schemes are formulated accordingly. The difference between the two schemes is that one is the second cycle sewage treatment of the processing link one, and the other is the sewage treatment of the processing link two according to the corresponding parameter control of the pretreatment water quality parameters. In order to select the best implementation scheme according to the energy saving of the energy consumption, the above information judgment and the formulation of multiple selectable schemes are used to reduce the probability of misjudgment in the data detection and analysis process, improve the efficiency of the sewage treatment work, and enhance the selectability of the diversity scheme.

[0032] The specific step S1 includes the following sub-steps:

[0033] The water quality characteristic data of the sewage to be purified is detected to obtain initial water quality parameters, the last sewage treatment link is marked as the processing link one and the next sewage treatment link is marked as the processing link two according to the sewage treatment sequence, the parameter scheduling is performed on the processing link one to obtain the implementation parameter one according to the initial water quality parameters, the historical treatment data of the historical sewage treatment is obtained, the water quality prediction model is established according to the historical treatment data, and the initial water quality parameters and the implementation parameter one are input into the water quality prediction model for testing to obtain the predicted water quality parameters.

[0034] The outlet belonging to the first treatment link is selected as the first main sampling point, the inlet belonging to the second treatment link is selected as the second main sampling point, the first main sampling point and the second main sampling point are combined into a main sampling point, the main sampling point is detected for sewage water quality characteristic data to obtain a main water quality parameter, if the main water quality parameter is the same as the predicted water quality parameter, the second treatment link performs parameter scheduling for sewage treatment according to the predicted water quality parameter, and a treatment scheme one is output.

[0035] Specifically, for water quality characteristic data (for example, chemical oxygen demand (COD), biochemical oxygen demand (BOD), total phosphorus, pH value, dissolved oxygen, chemical oxygen demand, ammonia nitrogen and the like), the first treatment link (for example, a pretreatment unit, a biological treatment unit, a deep treatment unit and a sludge treatment unit, each unit is a treatment step, if A, B, C and D symbols are used for marking, in order to facilitate subsequent illustration, if B and C are selected for illustration, the first treatment link is B), the amount of sewage purification drug, equipment operation parameters and the like of B are regulated according to the initial water quality parameter (the corresponding data scheduling matching can be performed according to the historical treatment data table, for example, the initial water quality parameter is S1, and (S1-S3)-T1 in the data corresponding table, T1 is the scheduled data value, that is, T1 is the implementation parameter one), historical treatment data (including scheduling parameters, sewage water quality characteristic data and sewage water quality characteristic data after sewage treatment in the historical period), a water quality prediction model (that is, machine learning is performed according to historical treatment data, for example, y=ax, wherein y represents the water quality characteristic data after treatment, a represents the sewage water quality characteristic data before treatment, and x represents the scheduling parameter of sewage treatment), a predicted water quality parameter (that is, the initial water quality parameter and the implementation parameter one are substituted into the above y=ax to test, that is, the predicted water quality parameter of B after treatment is y1), the second treatment link (if C), the main sampling point (if t1 and t2, if t1 and t2 are located on the same horizontal line), the main water quality parameter (if z1 and z2), and the treatment scheme one (if z1 and z2 are the same, and y1 is the same, it is indicated that the treatment process of the first treatment link is normal, that is, the sewage treatment result is normal, and the next treatment step of sewage treatment can be continued, that is, the second treatment link performs parameter scheduling for sewage treatment according to the predicted water quality parameter).

[0036] The specific step S2 includes the following sub-steps:

[0037] If one of the main water quality parameters is different from the predicted water quality parameter, three auxiliary sampling points are selected from the sewage pool formed between the first treatment link and the second treatment link to obtain auxiliary sampling points. The main sampling points and the auxiliary sampling points can be connected to form a parallelogram. The sampling point two in the main sampling points and the auxiliary sampling points divides the longest width of the sewage pool into two equal parts, and the auxiliary sampling points divides the longest length of the sewage pool into four equal parts.

[0038] The auxiliary water quality parameters are obtained by detecting the sewage water quality characteristic data of the auxiliary sampling points. The main water quality parameters and the auxiliary water quality parameters are integrated to obtain pre-processed water quality parameters. According to the pre-processed water quality parameters and the predicted water quality parameters, the current sewage treatment effect of the first treatment link is evaluated to obtain a current effect value one.

[0039] The historical effect data of the historical sewage treatment is obtained. According to the pre-processed water quality parameters, the current effect value one, and the effect data of the first treatment link in the historical effect data, the current actual effect value one of the first treatment link is evaluated. A preset effect threshold value is set. If the current actual effect value one is greater than or equal to the effect threshold value, the step one energy consumption value is obtained by counting the energy consumption of the secondary parameter scheduling control of the first treatment link.

[0040] Specifically, if the auxiliary sampling point (if the R1 and R2 data are the same, and different from the y1 data, or the R1 and R2 data are different, and both are different from the y1 data, or the R1 and R2 data are different, and R1 or R2 is the same as the y1 data, all of which indicate that the sewage treatment result of B is abnormal: the ideal treatment result is not reached, or the water quality characteristic data detected by the main sampling point has an error, then the secondary detection of other sampling points is needed to reduce the determination of which specific situation and to comprehensively detect the water quality characteristic data after the final treatment step to facilitate the continuous sewage treatment of the next processing step. Other sampling points cannot be selected arbitrarily, as the selection of sampling points should be avoided to be too concentrated, which may lead to the final detection result not being judged, and the sewage in the sewage tank should be detected uniformly. If f1, f2, and f3 are on the same horizontal line, f1 and f3 are connected by a straight line to form L1, t1 and t2 are connected by a straight line to form L2, and the intersection of L1 and L2 is f2, t1, f1, t2, and f3 are connected to form a parallelogram), auxiliary water quality parameters (if R3, R4, and R5 are respectively), pretreatment water quality parameters (if (R1+R2+R3+R4+R5) / 5 is y2), current effect value (if y2 / y1 is M1), historical effect data (including the sewage treatment effect data of each processing step), current actual effect value (the effect data of the processing step in the historical effect data includes different interval water quality parameters corresponding to the sewage treatment effect value: for example, the water quality parameters in the (y3-y6) interval correspond to the B step historical sewage treatment effect value g1, and the water quality parameters in the (y6-y8) interval correspond to the B step historical sewage treatment effect value g2. Only two examples are given here. According to y2, the corresponding effect value is g2, which is matched from the effect data of the processing step in the historical effect data. If G1=(M1+g2) / 2, G1 refers to the current actual effect value, and M1 refers to the current effect value), step one energy consumption value (if the current actual effect value is greater than or equal to the preset effect threshold value, it means that B can perform secondary cycle sewage treatment: because the effect meets the standard, the energy consumption degree of each processing step during sewage treatment is considered, and then it is further judged that if the energy consumption degree of C sewage treatment is smaller than that of B secondary cycle sewage treatment, the processing step with smaller energy consumption degree is selected for the next sewage treatment. Therefore, the effect value of C sewage treatment is analyzed), step one energy consumption value (the loss energy value of equipment operation and the energy value of drug amount for purification are comprehensively counted, and N1 is obtained).

[0041] The specific step S3 includes the following sub-steps:

[0042] The processing link two obtains an implementation parameter two according to the comprehensive parameter scheduling based on the pretreatment water quality parameter, and predicts a current actual effect value two of the processing link two after sewage treatment. If the pretreatment effect value two is greater than or equal to the effect threshold value, a step two energy consumption value is obtained by counting the energy consumption of the implementation parameter two scheduling control of the processing link two.

[0043] The step one energy consumption value and the step two energy consumption value are compared to obtain a to-be-measured energy consumption ratio. A determination energy consumption ratio threshold value is preset. If the to-be-measured energy consumption ratio is less than the determination energy consumption ratio threshold value, the sewage treatment of the processing link one according to the secondary parameter scheduling based on the pretreatment water quality parameter is selected, and a processing scheme two is output.

[0044] If the to-be-measured energy consumption ratio is greater than the determination energy consumption ratio threshold value, the sewage treatment of the processing link two according to the parameter scheduling based on the pretreatment water quality parameter is selected, and a processing scheme three is output.

[0045] If the current actual effect value one is less than the effect threshold value, the sewage treatment of the processing link two according to the parameter scheduling based on the pretreatment water quality parameter is selected, and a processing scheme three is output.

[0046] Specifically, if the implementation parameter two (the same as the explanation of the implementation parameter one, if T2), the current actual effect value two (the same as the explanation of the current effect value one, if G2), the step two energy consumption value (the same as the explanation of the step one energy consumption value, if N2, at this time, B and C can both perform the next step of sewage treatment, so it is necessary to further determine which one of B and C is the best next step of sewage treatment), the processing scheme two (if K1, the determination energy consumption ratio threshold value is the determination critical value, if it is greater than the critical value, it indicates that the energy consumption degree value of B is greater than that of C, otherwise, it indicates that the energy consumption degree value of B is less than that of C, the determination energy consumption ratio threshold value is obtained by counting the historical effect data, if K1 is less than the determination energy consumption ratio threshold value, B is selected as the best optimization of the next step of sewage treatment, that is, the sewage treatment of the processing link one according to the secondary parameter scheduling based on the pretreatment water quality parameter is selected), and the processing scheme three (if K1 is greater than the determination energy consumption ratio threshold value, C is selected as the best optimization of the next step of sewage treatment, that is, the sewage treatment of the processing link two according to the secondary parameter scheduling based on the pretreatment water quality parameter is selected. In addition, if the current actual effect value one is less than the effect threshold value, it indicates that B does not have the ability to perform secondary sewage treatment, so the sewage treatment of C is directly performed, that is, the sewage treatment of the processing link two according to the parameter scheduling based on the pretreatment water quality parameter is selected).

[0047] A sewage treatment remote scheduling control system, by applying a sewage treatment remote scheduling control method as described above, includes a scheme formulation unit one, a feature data counting unit, and a scheme formulation unit two, which refers to Figure 2, the scheme formulation unit one marks the previous sewage treatment link as treatment link one and the next sewage treatment link as treatment link two according to the sewage treatment sequence, detects the water quality of the sewage to be purified, schedules parameters for treatment link one, and if the water quality parameters after one sewage treatment by treatment link one are the same as the predicted water quality parameters, formulates treatment scheme one; the characteristic data statistical unit judges if the water quality parameters after one sewage treatment by treatment link one are not the same as the predicted water quality parameters, selects an auxiliary sampling point, re-detects the pretreated water quality parameters after one sewage treatment by treatment link one according to the auxiliary sampling, and according to the pretreated water quality parameters, counts the step one energy consumption value of the secondary parameter scheduling control of treatment link one; the scheme formulation unit two counts the step two energy consumption value of the sewage treatment of treatment link two according to the pretreated water quality parameters, and formulates treatment scheme two and treatment scheme three according to the to-be-measured energy consumption ratio between the step one energy consumption value and the step two energy consumption value.
