The waste water main channel is a channel for collecting waste water discharged from each sewage outlet, and is a key channel for monitoring the waste water discharge condition of the whole industrial park. By monitoring the wastewater main channel, all potential pollution events can be captured to the greatest extent, thereby ensuring the efficiency and the reaction speed of the whole monitoring system.
The first wastewater monitoring device is configured with high-precision sensors and analysis modules capable of detecting and analyzing various chemical components in the wastewater, including but not limited to organics, heavy metals, pH and other hazardous substances. Furthermore, these sensors are not only able to detect the presence of a specific contaminant, but also to accurately measure its concentration in order to compare it with stored emissions standards.
When an abnormal component is detected, the system sends first abnormal information to the processor through a preset communication module, such as a wireless transmitter or a wired network. The early warning information comprises key information such as specific types, contents and detection time of abnormal components exceeding standards. By rapidly identifying abnormal components exceeding the pollution discharge standard content, the subsequent tracing and early warning program can be rapidly started.

The second wastewater monitoring device is a device specifically designed for monitoring and analyzing the discharge of industrial wastewater, and has the functions of detecting main discharge components in the wastewater in real time, including but not limited to organic matters, inorganic matters, heavy metals, nutrient salts (such as nitrogen and phosphorus) and the like, and evaluating physicochemical properties (such as pH value, temperature, turbidity and the like) of the wastewater. The second wastewater monitoring device is typically equipped with high sensitivity sensors, sampling means and data processing units and is capable of automatic or semi-automatic water quality monitoring. In this application embodiment, the second wastewater monitoring device may be understood as a monitoring point deployed at a drain of each sewage enterprise in an industrial park for monitoring and recording the quality of wastewater discharged into the wastewater main by each enterprise.
A plurality of second wastewater monitoring devices are positioned at a plurality of wastewater outlets upstream of the wastewater main, each wastewater outlet being responsible for collecting wastewater discharge from a particular wastewater disposal facility. The core purpose of this kind of overall arrangement is in order to realize the accurate control and the data acquisition to blowdown source, ensures when the discovery waste water main road appears exceeding the standard and discharges, can trace back to specific blowdown enterprise.

Each second wastewater monitoring device can periodically or continuously collect wastewater samples at the sewage outlet, and the built-in sensors and analytical instruments of the second wastewater monitoring device are utilized to detect the pollution components in the samples. During the detection process, the device records the type and content of all detected contaminating components, which are then transferred to a processor for further processing and analysis. To determine the major emission component of each drain, the processor analyzes the data provided by the second wastewater monitoring device to identify the highest major emission component in each sample.

By acquiring the main emission component information of each enterprise at the upstream, and combining the generated abnormal components, the possible component combination capable of generating the abnormal components is deduced according to the analysis of the chemical reaction principle.
Specifically, a reaction database is queried to obtain a reaction equation for generating abnormal components, and the reaction equation is matched with known main emission components of each enterprise to obtain component combinations meeting the requirements of reactants, wherein the components contained in the combinations are possible pollution sources. Thus, blind monitoring and inspection can be avoided, and the most probable pollution source components are directly found out from the reaction principle. And finally, determining the specific sources of the abnormal components, namely, the abnormal pollution caused by the reaction of the chemical substances of the enterprises or the enterprises, thereby carrying out targeted early warning and treatment. The pollution source determining method based on the analysis reaction mechanism can improve the efficiency and accuracy of rapidly positioning the real pollution source enterprises.
The purpose of analyzing the plurality of main effluent components and the abnormal components is to reveal complex chemical reactions that may occur in the wastewater and to identify which combinations of components may result in the generation of abnormal effluent components. The system will analyze through an algorithm to obtain a range of possible combinations of principal emissions components. These combinations are based on knowledge of the chemical reaction, i.e. which components can react to produce the detected abnormal component. For example, if the abnormal component being monitored is a particular organic compound, the system will look for possible starting materials or intermediate combinations that are capable of producing the compound.
The reaction condition information corresponding to each combination refers to a specific set of parameters and environmental conditions that are necessary to enable the production of the abnormal component by the chemical reaction of the main emission component. Such reaction condition information generally includes, but is not limited to, temperature, pressure, pH, reaction time, type of solvent, presence or absence of catalyst, type of catalyst, and the like.
In the examples herein, reaction condition information is understood to be a set of key data that is used to assist in identifying chemical reactions that may occur in a particular industrial environment. By analyzing this condition information, it is possible to evaluate the various possible chemical reaction pathways and determine which pathways are viable in the current industrial emission environment.

And then, by comparing the first element types with the second element types, the elements which are the same as the abnormal elements in the emission components of the enterprises can be judged, and the abnormal elements can be generated by participating in the reaction.
For a first element category for which an abnormal component has been obtained, and for a second element category for which each enterprise discharges components. And then comparing the second element type with the first element type, and screening enterprise emission components of which the first element type exists in the second element type, wherein the enterprise emission components contain elements identical to the abnormal components, so that the emission components are primarily judged to possibly participate in the reaction for generating the abnormal components. These enterprise emissions components are thus determined to be the first major emissions component.
The possible reaction relationships between these components are analyzed according to the reaction principle and mechanism, based on the known abnormal components and the first main emission component. It is determined whether or not there is a combination of components that can collectively react to produce a given abnormal component on the basis of the first main emission component, and if so, it is recorded as the main emission component combination.

obtaining a chemical reaction formula with a reaction result being an abnormal component from a chemical reaction database;
and matching the plurality of main emission components with the chemical reaction formula to obtain a plurality of main emission component combinations capable of reacting to generate abnormal components.
First, according to known abnormal components, searching the existing chemical reaction database for chemical reactions generating the abnormal components. The chemical reaction database collects a large number of known chemical reaction equations, and chemical reactions related to abnormal components can be rapidly obtained by querying. The major emissions components of each business are then matched against the chemical reaction formulas obtained. And judging which components in the main emission components accord with reactants in the reaction formula, namely, the components can be used as component combinations for generating abnormal components through reaction. Thus, by matching the existing chemical reaction databases, the reaction analysis link can be skipped, and the possible reaction component combinations can be rapidly determined.
S104: acquiring the environmental information of the wastewater in the wastewater trunk;
the environmental information of the wastewater contains various components, pH value, temperature and other parameters in the wastewater. These parameters reflect the environmental conditions of the actual wastewater. The wastewater environmental information refers to monitoring data reflecting wastewater components and environmental parameters in a wastewater main channel, and in the embodiment of the application, the monitoring data is used for comparing with possible reaction condition information to judge the reaction condition most likely to generate the detected abnormal components so as to determine the generation reaction of the abnormal components and the corresponding pollution source component combination.
Optionally, on the basis of the foregoing embodiment, as an optional embodiment, S104 may further include the following steps:
analyzing the first abnormal information to obtain first wastewater environment information;
acquiring a plurality of pieces of second wastewater environment information acquired by a plurality of pieces of second wastewater monitoring equipment;
and integrating the first wastewater environment information and the plurality of second wastewater environment information to obtain the wastewater environment information in the wastewater trunk.
In order to obtain comprehensive information reflecting the overall environmental condition of the waste water trunk, the first waste water environmental information obtained by analyzing the first abnormal information and the second waste water environmental information obtained by the second monitoring equipment are required to be integrated.
First, the first abnormal information is analyzed in detail, parameters such as temperature, pH value and the like are extracted, and first wastewater environment information is formed. This may reflect the environmental condition of the wastewater at the point of abnormal discharge.
Meanwhile, the system acquires a plurality of parameters such as temperature, pH value and the like at the outlet of each enterprise in real time by controlling a plurality of second monitoring devices at the upstream to obtain a plurality of second wastewater environment information.
The wastewater environment information of the first monitoring equipment and the second monitoring equipment is integrated, so that the water quality condition of the wastewater main road can be monitored from more angles and a larger range, and errors caused by local reasons of a single detection point are avoided. The sample size and the detection range are increased, so that sporadic anomalies among all detection points can be smoothed, and the overall wastewater environmental characteristics can be reflected better.
S105: and comparing the similarity of the reaction condition information with the wastewater environment information, and determining the main emission component combination corresponding to the reaction condition information with the highest similarity as the pollution source component combination.
After the environmental information of the wastewater is collected, this may include, but is not limited to, temperature, pH, dissolved oxygen content, organic concentration, and other chemical content of the wastewater, etc. These actual measurements are then compared with the theoretical reaction condition information corresponding to each of the previously derived combinations of potential pollution source components using a pre-designed algorithm or data analysis model. This comparison process involves calculating the similarity between each theoretical reaction condition and the actual wastewater environmental information.
By such comparison, a similarity score or index can be derived that reflects how well each set of theoretical reaction conditions match the actual wastewater environmental information. Finally, the main emission component combination corresponding to the reaction condition information with the highest similarity score is selected as the pollution source component combination.
By way of example, assuming that theoretical reaction conditions indicate that a particular organic compound will produce an abnormal component at a pH of 5 and a temperature of 60 ℃, the actual wastewater environmental information indicates that the wastewater has a pH of 5.2 and a temperature of 58 ℃. If the actual information has the highest similarity score to the theoretical reaction conditions, the system will locate this primary emission constituent combination as the pollution source constituent combination.
Optionally, on the basis of the foregoing embodiment, as an optional embodiment, S105 may further include the following steps:
obtaining a reaction condition range of a plurality of pieces of reaction condition information;
removing first reaction condition information, in which the reaction condition range does not accord with the wastewater environment information, in the plurality of reaction condition information to obtain a plurality of second reaction condition information;

and comparing the similarity between the optimal reaction conditions of the plurality of pieces of second reaction condition information and the wastewater environment information, and determining the main emission component combination corresponding to the second reaction condition information with the highest similarity as the pollution source component combination.
The range of reaction conditions may be based on previous experimental data, literature or existing databases, including temperature ranges, pH ranges, concentration ranges, etc. where the reaction may occur. For each reaction condition information, it is checked whether its corresponding reaction condition range coincides with the actual wastewater environment information. Non-conforming reaction condition information, i.e., those whose reaction condition ranges are significantly different from the wastewater environmental information, will be removed. In this way, the system obtains all the second reaction condition information which accords with the actual wastewater environment information range.
Further, the system needs to obtain the optimal reaction conditions from these second reaction condition information. This includes determining the specific reaction conditions in each reaction condition information that are most likely to contribute to the formation of the abnormal component, such as optimum temperature, pH, and other relevant environmental factors.
Finally, the system will compare the similarity of these optimal reaction conditions to the actual wastewater environmental information. And calculating second reaction condition information with highest similarity, and determining the corresponding main emission component combination as a pollution source component combination.

And screening out the sewage outlet for discharging the specific component by comparing the discharge record and the environment monitoring data of each sewage outlet by utilizing the determined target sewage outlet component. The target drain may be determined by associating the target drain component with a particular drain.

This database should include information on the type of emissions of the business, historical emissions data, production campaign information, existing environmental protection measures, etc. The data analysis and monitoring system finds that the emission data of a certain target pollution discharge enterprise is abnormal or close to the regulation limit value, and the system automatically sends an early warning signal to the enterprise. The information can be transmitted in time through various channels, such as short messages, mails, application program notices and the like.

if the content change trend of the abnormal components is a decreasing trend, processing information is generated and sent to a target sewage disposal enterprise, and the processing information is used for suggesting the target sewage disposal enterprise to connect the target sewage disposal outlet to the newly-added sewage disposal pipeline.
The third wastewater monitoring device is arranged at the downstream of the first wastewater monitoring device and is used for continuously tracking the content of specific abnormal components in wastewater. When the system is deployed, enough coverage and proper monitoring points are considered to ensure that the change trend of the abnormal component can be accurately captured.
The monitoring device can detect the specific content of abnormal components in the wastewater by a real-time online monitoring technology such as a spectrum analysis method, an electrochemical sensor method and the like. These data are transmitted in real time to the processor for analysis and generation of content trends.
When the monitoring data shows that the abnormal component content shows a decreasing trend, this shows that the measure of closing the target drain is effective. In this case, the supervisory system will generate process information including confirmation of the abnormal component reduction trend and further advice.
