The processing device 110 may be implemented on a cloud platform.
The rainwater 120 may be rainwater within a plant area. In some embodiments, stormwater 120 may be treated by stormwater treatment device 130. For example, rainwater 120 at the beginning of rain may be treated by rainwater treatment device 130. When the rainwater 120 needs to be treated by the rainwater treatment apparatus 130, the rainwater 120 may be collected through a rainwater ditch (not shown) provided in the factory floor. In some embodiments, rainwater 120 may also be discharged directly to rainwater drain 150. For example, the late-stage rain 120 may be discharged directly to the rain drain 150.
The rainwater treatment apparatus 130 may be an apparatus that performs a purification treatment on the rainwater 120.

Fig. 2 is an exemplary flow chart of rain water utilization according to some embodiments described herein. In some embodiments, flow 200 may be performed by processing device 110. As shown in fig. 2, the process 200 includes the following steps:
The rain data may be data relating to rain in the plant. In some embodiments, the rain data may include target rainfall information, historical rainfall information, and factory floor production information. The target rainfall information may be rainfall information of rainwater under or about to be under the plant area. For example, the size of the current rainfall, the range of the current rainfall, the duration of the current rainfall, the number of rainings and the time of rainfall for the next day or week, etc. The historical rainfall information may be rainfall information of the plant over a period of time. For example, the average rainfall of the plant area over the last months or years, the average length of time the rain falls, the size of each rain fall, and the like. The factory floor production information can be information related to factory floor production. For example, the type of plant (e.g., cement plant, cardboard production, etc.), the amount of production in the plant, the manner of production in the plant, the layout of the production machines in the plant, etc.
In some embodiments, rain data such as target rainfall information, historical rainfall information, and factory production information may be obtained in various feasible ways. For example, the target rainfall information may be acquired based on weather forecast and/or a rainfall sensor or the like. For another example, historical rainfall information may be obtained by querying historical data of a relevant website (weather website) or factory floor. For example, the production information of the factory floor can be obtained by looking over the related files of the factory floor.
The first rainwater may be rainwater directly discharged after purification treatment. In some embodiments, rainwater may be collected through a storm drain within the plant area over a first period of time to obtain a first rainwater. The first time period may be a time period during which the first rain is collected.
In some embodiments, the first time period may be determined based on target rainfall information, historical rainfall information, and factory floor production information. In some embodiments, the first time period may be determined according to the target rainfall information, the historical rainfall information, and the factory production information by presetting the corresponding relationship. For example, according to the preset corresponding relation, it can be determined that the first 15min of rainwater needs to be collected under the condition of average rainfall of the factory production information. According to the preset corresponding relation, the historical rainfall information shows that the rainfall influences the collecting time length (namely, the rainwater in the first 15min needs to be collected under the condition of average rainfall, and when the rainfall is smaller than the average rainfall, the rainwater after 15min possibly still does not accord with the discharge regulation, the collecting time can be properly prolonged), so that the first time period for collecting the first rainwater can be properly prolonged (for example, prolonged to 17min) when the target rainfall information shows that the current rainfall is smaller than the average rainfall according to the preset corresponding relation.
Some embodiments in this specification may reduce the usage of the water quality monitoring device by determining the first time period based on the target rainfall information, the historical rainfall information, and the factory floor production information according to the preset correspondence, so as to further reduce the production cost.
In some embodiments, the first time period may be determined based on a degree of contamination of the rainwater. The degree of pollution of the rainwater can be used for representing the degree of pollution of the rainwater. The degree of contamination by rainwater can be represented by a number from 0 to 100. For example, a time period in which the degree of contamination of rainwater in the current rainfall is 80 to 100 may be taken as the first time period.
In some embodiments, the degree of contamination of the rainwater may be obtained in various possible ways. For example, the degree of pollution of rainwater may be acquired by a water quality monitoring device.
In some embodiments, the pollution level can also be determined according to target rainfall information, historical rainfall information, and factory floor production information. The target rainfall information, the historical rainfall information, the factory production information and the time information of a certain time period in the target rainfall process can be processed based on the pollution degree determination model, the pollution degree of rainwater in the time period is determined, and the first time period is determined based on the determined pollution degree. The time information of each time period in the target rainfall process may be a start time and an end time of the time period.
For example, target rainfall information, historical rainfall information, plant production information, and time information of a certain period of time during target rainfall may be input to the pollution degree determination model, so that it is determined that the pollution degree of rainwater is 100 when the period of time is 0min, the pollution degree of rainwater is 90 when the period of time is 5min, the pollution degree of rainwater is 80 when the period of time is 10min, and the pollution degree of rainwater is 79 when the period of time is 11 min. When the preset condition is that the time period in which the degree of pollution of rainwater is 80-100 is taken as the first time period, the first 10min in the target rainfall process can be taken as the first time period.
In some embodiments, the pollution level determination model may be trained based on historical data. In some embodiments, rainfall information of a sample time period, rainfall information of a historical time period, factory production information, and time information of a certain time period in a target rainfall process of the sample time period may be used as a training sample, and a label of the training sample may be a pollution degree of rainwater in the time period in the target rainfall process of the sample time period, where the sample time period is a time period after the historical time period. Inputting a plurality of training samples with labels into an initial pollution degree determination model, updating parameters of the initial pollution degree determination model through training, and finishing the training when the trained model meets preset conditions to obtain the trained pollution degree determination model. In some embodiments, the pollution level determination model includes, but is not limited to, a support vector machine model, a naive bayes classification model, a gaussian distribution bayes classification model, a decision tree model, a random forest model, a neural network model, and the like.
Some embodiments of this description confirm the pollution degree of model through the pollution degree and confirm first time quantum, can improve the rate of accuracy of the pollution degree of the rainwater that obtains to determine first time quantum fast accurately, reduce the human cost.
The second rainwater can be rainwater which needs to be treated for production and use in a factory. In some embodiments, rainwater may be collected through a storm drain in the plant area during the second period of time to obtain the second rainwater. The second period of time may be a period of time for collecting the second rain water.
In some embodiments, the second period of time may be determined based on a degree of contamination of the rainwater. For example, rainwater having a degree of contamination of 60 to 80 may be taken as the second rainwater, and a period of time during which the second rainwater is collected may be taken as the second period of time.
In some embodiments, a first and second purification cost of purifying the stormwater may be determined from the stormwater data, and the first and second time periods may be determined based on the first and second purification costs. For more details of determining the first time period and the second time period based on the cost, refer to fig. 3 and the related description thereof, which are not repeated herein.
In some embodiments, the first time period and the second time period may also be determined in other ways. In some embodiments, the rainwater data may be water quality monitoring data of rainwater of the plant area. The water quality monitoring data may be data on the aspect of rainwater quality obtained by monitoring current rainfall. The water quality monitoring data may be obtained by a water quality monitoring device for monitoring water quality. In some embodiments, the first time period and the second time period are determined based on water quality monitoring data. The rainfall starting moment can be used as the starting moment of a first time period, the rainwater can be continuously collected in the early stage of rainfall, the rainwater is continuously detected through the water quality monitoring equipment to obtain water quality monitoring data at all moments, the water quality monitoring data are compared with a first preset water quality threshold value, when the water quality monitoring data at a certain moment are smaller than the first preset water quality threshold value, the moment is used as the first time period, so that the first time period is determined, the moment is used as the starting moment of a second time period, the rainwater is continuously collected and the water quality monitoring data are obtained through the water quality monitoring equipment, the water quality monitoring data are compared with the second preset water quality threshold value, and when the water quality monitoring data at another moment are smaller than the second preset water quality threshold value, the moment is used as the second time period, so that the second time period is determined. The rainwater after the second period of time may be directly discharged without being collected. The first preset water quality threshold and the second preset water quality threshold can be preset and determined by experience.
Some embodiments in this specification can make the prediction more accurate by acquiring the water quality monitoring data of the rainwater and determining the first time period for collecting the first rainwater and the second time period for collecting the second rainwater, thereby avoiding the problems that the rainwater needing the first purification treatment is excessively wasted due to the excessively long time for collecting the first rainwater and the rainwater partially not meeting the discharge standard is discharged due to the excessively short time for collecting the first rainwater. Some embodiments in this specification determine the second time period for collecting the second rainwater, so that the second rainwater can be collected in time in the corresponding time period of the target rainfall process, thereby avoiding rainwater waste caused by untimely reaction and standardizing the collection flow of the second rainwater.
And step 220, discharging the first rainwater after the first purification treatment. In some embodiments, step 220 may be performed by the first purification module 520.
In some embodiments, a first purification treatment may be performed on a first rain water collected over a first time period. The first rainwater after the first purification treatment can be directly discharged. The first purification treatment may be a purification treatment of the first rainwater, and the first rainwater after the first purification treatment may reach a discharge standard. The first purification treatment may include, but is not limited to, separation of insoluble contaminants, neutralization of acid and base, and degreasing.
And step 230, storing the second rainwater for production and use after the second purification treatment, wherein the purification standard of the second purification treatment is higher than that of the first purification treatment. In some embodiments, step 230 may be performed by the second purification module 530.
In some embodiments, a second purification treatment may be performed on a second rain water collected over a second time period. The second rainwater after the second purification treatment can be used for production and use in a factory. The second purification treatment can be the purification treatment to the second rainwater, and the second rainwater after the second purification treatment purifies and can reach the process water standard. In some embodiments, the second purification treatment may include, but is not limited to, softening clarification, two-stage filtration, reverse osmosis, and the like.
In some embodiments, the second decontamination process has a higher decontamination criteria than the first decontamination process. The purification standard may be a predetermined standard for purifying the treated rainwater. The purification criteria may be determined in various feasible ways, including but not limited to determining according to the pollution degree of the purified rainwater, determining based on the error range of the quality of the purified rainwater and the specified standard quality, determining based on the complexity of the purification treatment, etc. The degree of contamination of rainwater obtained after the second purification treatment should be lower than the degree of contamination of rainwater obtained after the first purification treatment, the quality of rainwater obtained after the second purification treatment should be within the range of quality of water specified by the process water, and the quality of rainwater obtained by the first purification treatment should be within the range of quality of water specified by the emission standard, wherein the range of quality of water specified by the process water is higher than the range of quality of water specified by the emission standard, and the complexity of the second purification treatment is higher than the complexity of the first purification treatment, and the like, it can be considered that the purification standard of the second purification treatment is higher than that of the first purification treatment.
According to some embodiments of the specification, a first time period for collecting first rainwater and a second time period for collecting second rainwater are determined according to rainwater data, the first rainwater is subjected to first purification treatment and then discharged, and the second rainwater is subjected to second purification treatment and then used for production, so that part of rainwater which does not accord with the discharge standard can be treated and then used as factory production water, the production cost is reduced, and the collection of the production water is reduced.
Fig. 3 is an exemplary flow chart illustrating determining a second time period according to some embodiments of the present description. In some embodiments, flow 300 may be performed by processing device 110. As shown in fig. 3, the process 300 includes the following steps:
at step 310, based on the rain data, various time periods during the target rainfall are determined.
The target rainfall process may be a rainfall process of the plant area in a future time period. In some embodiments, the entire target rainfall process may be divided into a plurality of time periods according to the target rainfall information. For example, for the entire target rainfall process lasting 20min, it may be divided into four periods of 0-5min, 5-10min, 10-15min, and 15-20min at 5min intervals.
In some embodiments, the first and second purification costs may be calculated separately for stormwater collected over different time periods. For example, for each of the four periods in the example in step 310, a first purification cost and a second purification cost required for performing a first purification treatment and a second purification treatment on rainwater collected during the period are calculated.
The first purification cost may be a cost of performing the first purification treatment on the rainwater collected within a certain period of time. For example, the first purification cost may be considered as a capital consumed directly or indirectly by a medicine, a purification site, power consumption, and the like used when the rainwater collected during the period is subjected to the first purification treatment.
The second purification cost may be a cost of performing the second purification treatment on the rainwater collected within a certain period of time. For example, funds consumed directly or indirectly by drugs, purification sites, storage sites for power consumption, and the like, which are used when rainwater collected during the period of time is subjected to the second purification treatment, may be regarded as the second purification cost.
In some embodiments, the first and second purification costs of rainwater in each time period during the target rainfall may be determined by a preset cost rule according to the rainwater data. For example, the cost unit prices of the first purification treatment and the second purification treatment on 0-5min rainwater are determined to be 100 yuan/ton and 200 yuan/ton, respectively, through a preset cost rule. Therefore, the total amount of collected rainwater within 0-5min, such as 3 tons, may be determined based on the target rainfall information, so that the first purification cost of purifying the rainwater may be determined to be 300 yuan and the second purification cost may be determined to be 600 yuan.
In some embodiments, the rain data and time information for each time period during the target rainfall may be input into a first cost determination model that outputs a first cost of decontamination and a second cost of decontamination for the corresponding time period.
In some embodiments, time information of each time period in a sample target rainfall process and rainwater data corresponding to the target rainfall process may be used as a training sample, and a label of the training sample may be a first purification cost and a second purification cost of each time period in the sample target rainfall process, where the training sample may be obtained through historical data, and the label of the training sample may be obtained through manual labeling based on the historical data. Inputting a plurality of training samples with labels into an initial first cost determination model, updating parameters of the initial first cost determination model through training, and finishing training when the trained model meets a preset condition to obtain the trained first cost determination model. In some embodiments, the first cost determination model includes, but is not limited to, a support vector machine model, a naive bayes classification model, a gaussian distributed bayes classification model, a decision tree model, a random forest model, a neural network model, and the like.
Some embodiments of the present description determine the first and second purification costs of the rainwater through the first cost determination model, which may improve accuracy of the obtained purification costs and reduce labor costs.
In some embodiments, for each time period during the target rainfall, determining a pollution level of the rainwater collected during the time period based on the rainwater data; and determining a first purification cost for performing first purification treatment on the rainwater in the time period and a second purification cost for performing second purification treatment on the rainwater in the time period based on the pollution degree.
In some embodiments, the rain data and time information for a period of time during the target rainfall may be input into a pollution level determination model that outputs a pollution level of rain for the period of time. For more details on the pollution degree determination model, refer to fig. 2 and the related description thereof, which are not repeated herein.
In some embodiments, a first purification cost for performing a first purification treatment and a second purification cost for performing a second purification treatment on rainwater in a certain time period may be determined based on a pollution degree of the rainwater in the certain time period. In some embodiments, the first purification cost and the second purification cost of the rainwater may be determined by a pollution degree of the rainwater based on a preset rule. For example, the preset rule may be that for rainwater with a pollution degree of 90 to 100, the unit cost for performing the first purification treatment may be 100 yuan/ton, and the unit cost for performing the second purification treatment may be 200 yuan/ton. The total amount of rainwater in a certain time period in the target rainfall process is 3 tons, the rainwater pollution degree is 95, and the first purification cost and the second purification cost for treating the rainwater can be respectively 300 yuan and 600 yuan.
In some embodiments, the pollution degree of rainwater and the rainwater data of a certain time period output by the pollution degree determination model may be input into the second cost determination model, and a first purification cost for performing the first purification treatment and a second purification cost for performing the second purification treatment on the rainwater of the certain time period may be output. In some embodiments, the pollution level determination model and the second cost determination model may be obtained by performing joint training based on historical data. In some embodiments, time information of a certain time period in the sample target rainfall process and the rainwater data corresponding to the target rainfall process may be used as training samples, and the labels of the training samples may be the first purification cost and the second purification cost of each time period in the sample target rainfall process. Inputting a training sample into an initial pollution degree determination model, inputting the output of the initial pollution degree determination model into an initial second cost determination model, constructing a loss function based on the output of the initial second cost determination model and a label, and simultaneously iteratively updating the parameters of the initial pollution degree determination model and the initial second cost determination model based on the loss function until preset conditions are met, finishing training, and obtaining the trained pollution degree determination model and the trained second cost determination model.
Some embodiments in this specification determine the pollution degree of the rainwater through the pollution degree determination model, and then determine the first purification cost and the second purification cost based on the pollution degree, so that the costs of respectively performing the first purification treatment and the second purification treatment on the rainwater can be accurately obtained under the condition of discontinuous rainfall, and the accuracy of the calculated purification cost is improved.
In some embodiments, for each time period in the target rainfall process, acquiring the total amount of rainwater in the time period; determining the collection cost for collecting raw water with the total quantity same as that of the rainwater on the basis of the total quantity of the rainwater; when the first purification cost is less than or equal to the difference value between the second purification cost and the acquisition cost, determining that the time period belongs to a first time period; and when the first purification cost is larger than the difference value between the second purification cost and the acquisition cost, determining that the time period belongs to a second time period. For more description of the above embodiments, refer to fig. 4 and its related description, which are not repeated herein.
In some embodiments, the time period may also be determined to belong to the first time period or the second time period based on the first cost of purging and the second cost of purging by other means. For example, the first time period and the second time period may be determined based on the first cost and the second cost of purging by a preset rule. For example, the preset rule may be that when the ratio of the second decontamination cost to the first decontamination cost is greater than 4:3, the time period is determined to belong to the first time period; when the ratio of the second decontamination cost to the first decontamination cost is less than or equal to 4:3, determining that the time period belongs to the second time period.
Some embodiments of the present description further reduce production costs by determining a first purification cost and a second purification cost per time period during a target rainfall and determining the first time period and the second time period based on the first purification cost and the second purification cost, so that a lower cost purification manner can be used as a manner of purifying rainwater collected during the time period.
FIG. 4 is a schematic illustration of determining a first time period and a second time period, shown in accordance with some embodiments of the present description. In some embodiments, the content illustrated in diagram 400 may be executed by processing device 110.
At step 410, the target rainfall process is divided into a plurality of time periods. As shown in FIG. 4, the target rainfall process may be divided into n +1 time periods, t respectively0-t1、t1-t2、…、tn-tn+1. For example, the target rainfall event is a 20min rainfall, which may be divided into four time periods of 0-5min, 5-10min, 10-15min, and 15-20 min.
In step 420, for each time period in the target rainfall process, the total amount of rain in the time period is determined. As shown in FIG. 4, a time period t may be obtained0-t1Corresponding total rainwater amount 1 and time period t1-t2Corresponding total rainwater amount 2, … and time period tn-tn+1Corresponding total amount of rain n + 1.
In some embodiments, the total amount of rain over various time periods of the target rainfall event may be determined based on the target rainfall information. For more about the target rainfall information, refer to fig. 2 and the related description thereof, which are not repeated herein.
And step 430, determining the collection cost for collecting raw water with the same total amount as the total amount of the rainwater based on the total amount of the rainwater in each time period.
The collection cost may be the cost of collecting raw water of the same total amount as the total amount of rainwater. For example, if the total amount of rainwater is 6 tons, the collection cost may be the cost of collecting 6 tons of river water from the river for production.
In some embodiments, a collection cost unit price for collecting a certain total amount of raw water may be determined through a history of raw water collection in a plant area and/or related data, and then a collection cost for the time period may be determined based on the collection cost unit price and a corresponding total amount of rainwater. For example, the total amount of rainwater collected in a certain time period is 6 tons, and it can be determined through the historical records of raw water collected in a plant area that the unit price of the raw water collection cost is 6 yuan/ton, and then the collection cost of the time period is 36 yuan.
And step 450, when the first purification cost of the time period is less than or equal to the difference value between the second purification cost and the acquisition cost, determining the time period as a first time period.
It should be understood that when the rainwater is subjected to the second purification treatment, the rainwater may be put into use again, and the collection of raw water may be reduced, thereby reducing the collection cost of raw water. However, since the second purification cost is larger than the first purification cost for rainwater of the same volume, the second purification cost, the first purification cost and the collection cost need to be measured to determine the optimal purification treatment mode corresponding to rainwater. When the first purification cost is less than or equal to the difference between the second purification cost and the collection cost, the total production cost generated by treating the rainwater in the time period in the first purification treatment mode in the factory is lower than or equal to the total production cost generated by treating the rainwater in the time period in the second purification treatment mode. Therefore, in order to achieve lower production costs and avoid waste of resources, the period may be determined as the first period.
And 460, when the first purification cost of the time period is larger than the difference value between the second purification cost and the acquisition cost, determining the time period as a second time period.
For example, 7 tons of rainwater are collected in 5-10min, the first purification cost for treating the rainwater is 560 yuan, the cost of the second purification treatment is 1050 yuan, and the collection cost is 420 yuan, so that 5-10min can be used as the first time period. For another example, since 6 tons of rainwater are collected in 10 to 15 minutes, the first purification cost for treating the rainwater is calculated to be 420 yuan, the second purification cost is calculated to be 720 yuan, and the collection cost is calculated to be 360 yuan, 10 to 15 minutes can be used as the second time period.
It should be understood that when the first purification cost is greater than the difference between the second purification cost and the collection cost, the total production cost of the plant area for treating the rainwater of the time period by the first purification treatment is greater than the total production cost of the plant area for treating the rainwater of the time period by the second purification treatment, and therefore, in order to achieve a lower production cost, the time period may be determined as the second time period.
Some embodiments in the present description may further reduce production costs by determining a collection cost for collecting a corresponding total amount of raw water, and determining the first time period and the second time period based on the first purification cost, the second purification cost, and the collection cost.
