As a preferred embodiment of the present invention, the obtaining pollution data includes at least quality data of groundwater in a sub-area detected by an acquisition end, wherein a plurality of acquisition ends for acquiring the quality data are distributed in a level in the sub-area of the monitoring area, and specifically includes:
step S101: the method comprises the steps that a collection end is controlled to synchronously collect quality data of underground water in a sub-area every interval preset collection period, and the collection ends are distributed in the sub-area of a detection area in a hierarchical mode;

As a preferred embodiment of the present invention, the determining whether the concentration of the contaminants in the quality data is lower than the corresponding first concentration limit value specifically includes:
step S111: comparing the pollutant concentration in the quality data with a first concentration limit value of a level of a subregion where a corresponding acquisition end is located, wherein the pollutant concentration comprises one or more of pH value, permanganate pollutant concentration, total hardness, chloride pollutant concentration and sulfide pollutant concentration, and detection of the pollutant concentration can be completed by adopting a fusion sensor, and the method belongs to a common technical means in the existing pollution detection.
As shown in fig. 2, as a preferred embodiment of the present invention, if not, reporting the quality data step by step from the acquisition end of the quality data with the first contaminant concentration reaching the first concentration limit value and the corresponding acquisition end identification information specifically includes:
step S121: positioning a first acquisition end reaching a first concentration limit value, starting from the acquisition end, transmitting the pollutant concentration acquired by the acquisition end and the identification code of the acquisition end to a next acquisition end at a relatively high level, after the next acquisition end at the relatively high level receives corresponding data, transmitting the pollutant concentration and the identification code acquired by the acquisition end and the received corresponding data to the next acquisition end at the relatively high level, and the like until all corresponding data except the topmost acquisition end are transmitted to the topmost acquisition end;
step S122: all corresponding data are reported through the topmost collecting end, and all corresponding data comprise the pollutant concentrations collected by all collecting ends meeting the conditions and the identification codes of the collecting ends.
In application, the pollutant concentration and the identification code of the collecting end are sent to the collecting end at the next relatively high level after the collecting end at the next relatively high level receives the corresponding data, and the data are reported in the mode, so that the requirements on the communication capacity of the transmitting module and the collecting module of each collecting end are lower, the total communication path between the collecting ends distributed in a level mode is as shortest as possible, and the cost of wireless communication data transmission is saved.
As shown in fig. 3, as a preferred embodiment of the present invention, when it is detected that the quality data has a higher concentration of the contaminant at the relatively lower layer than the contaminant at the relatively higher layer during the progressive reporting process, determining whether the deep-layer pollution discharge behavior is possible according to the pollution discharge data of the monitored area within the preset period specifically includes:
step S1311: the quality data reported by the last acquisition end is received, the pollutant concentration acquired by the acquisition end in the quality data is analyzed, and the pollutant concentration is compared with the pollutant concentration corresponding to the level;
step S1312: when the pollutant concentration is not lower than the pollutant concentration corresponding to the level, analyzing the corresponding pollutant concentration type, and directly reporting the pollutant concentration and the identification code corresponding to the pollutant concentration type and the identification code across the subsequent acquisition end;
step S1313: acquiring the concentration of all directly reported pollutants and the logarithm of the acquisition end of the identification code;
step S1314: classifying the paired acquisition ends according to the pollutant concentrations respectively, and judging whether the logarithm of the acquisition end corresponding to each pollutant concentration is greater than 1;
step S1315: the paired acquisition ends are arranged in the forward direction from low to high according to the depth information;
step S1316: when the logarithm of the collection end corresponding to each pollutant concentration is larger than 1 and the serial numbers corresponding to the collection ends of different logarithms are the same, preliminary judgment is performed to possibly have continuous-level deep sewage discharge behaviors;
step S1317: when the logarithm of the acquisition end corresponding to each pollutant concentration is larger than 1 and the serial numbers corresponding to the acquisition ends of different logarithms are different, preliminary judgment can be performed to ensure that deep sewage draining behaviors crossing the hierarchy exist;
step S1318: and calculating the depth range covered by the continuous-level deep-layer blowdown behaviors through the identification code of the acquisition end, and crossing the depth range covered by each of the level deep-layer blowdown behaviors.
It should be appreciated that the pairs of collection ends are each classified by contaminant concentration, i.e., by pH, permanganate, total hardness, chloride, sulfide, etc., where there is the same between the corresponding serial numbers of collection ends having a log greater than 1 for each contaminant concentration and different log for the collection ends, meaning that the concentration of contaminants in the relatively lower layer is continuously detected between the pairs of collection ends to be higher than the concentration of contaminants in the relatively higher layer, i.e., there may be deep blowdown in each of the successive levels, rather than deep blowdown in one of the levels, and similarly, the preliminary determination may be deep blowdown in each of the levels spanning the range of levels where deep blowdown behavior may exist.
As shown in fig. 4, as a preferred embodiment of the present invention, the calculating, by the identification code of the collection end, the depth range covered by the continuous-level deep-layer sewage draining behavior and the depth range covered by the cross-level deep-layer sewage draining behavior specifically includes:
step S13181: analyzing depth information in identification codes of acquisition ends of different logarithms;
step S13182: calculating a depth range covered by continuous-level deep sewage discharge behaviors through the depth information, and subtracting the depth information of continuous paired acquisition ends;
step S13183: and calculating the depth range covered by each deep sewage discharge behavior crossing the hierarchy through the depth information, and subtracting the depth information of each pair of acquisition ends.
In the application of the embodiment, because the identification code is generated and correlated with the depth information, the depth range covered by the continuous-level deep-layer sewage draining behaviors or the depth range covered by the deep-layer sewage draining behaviors crossing the levels can be calculated through the distribution of the acquisition ends of different logarithms.
As shown in fig. 5, as a preferred embodiment of the present invention, when it is detected that the quality data has a higher concentration of the contaminant at the relatively lower layer than the contaminant at the relatively higher layer in the progressive reporting process, determining whether the deep-layer pollution discharge behavior is possible according to the pollution discharge data of the monitored area within the preset period specifically further includes:
step S1321: acquiring pollutant in the pollutant discharge data in a preset period, wherein the pollutant is the same as the pollutant type in the pollutant discharge behavior of the deep layer of the continuous layer or the pollutant in the pollutant discharge behavior crossing the deep layer of the layer, which is judged to exist in the preliminary step;
step S1322: obtaining the average flow rate and the pollution discharge time of pollutants with the same pollutant type, and calculating the theoretical arrival depth range of the pollutants with the same pollutant type in the theoretical duration after pollution discharge according to the average flow rate and the pollution discharge time, wherein the theoretical duration is the difference between the acquisition time and the pollution discharge time of paired acquisition ends;
step S1323: judging whether the theoretical reaching depth range is in the depth range covered by the continuous-level deep-layer sewage drainage behaviors or the depth range covered by the crossing-level deep-layer sewage drainage behaviors, if not, judging that the deep-layer sewage drainage behaviors possibly exist.
It will be appreciated that, since the detection times of the paired collection ends are the same, the difference between the two durations is the theoretical duration, where the theoretical duration is the penetration or flow duration of the pollutant from the point of discharge (typically at the surface location) to the subsurface, where the average flow rate is a theoretical value obtained according to the characteristics of the pollutant, and the average flow rates of different pollutants may be different from each other, and also related to the soil structure in the area, if the theoretical arrival depth range is within the depth range covered by the continuous-level deep-layer discharge behavior or the depth range covered by each of the deep-layer discharge behaviors crossing the level, then if the concentration of the pollutant in the last relatively lower layer is higher than that in the relatively higher layer due to the accumulation of normal emissions under the irregular structure of the soil, and therefore, if it is determined that the theoretical arrival depth range is not within the depth range covered by the continuous-level deep-layer discharge behavior or the depth range covered by each of the deep-layer discharge behaviors crossing the level deep-layer discharge behavior, then the probability of determining that the deep-layer discharge behavior exists is relatively high is determined.
As another preferred embodiment of the present invention, as shown in fig. 6, in another aspect, an intelligent wireless monitoring system for groundwater pollution, the system comprises:
the acquisition module 100 is configured to acquire pollution data, where the pollution data at least includes quality data of groundwater in a sub-area, and a plurality of acquisition ends for acquiring the quality data are distributed in a hierarchy in the sub-area of the monitoring area;
