Description

Technical Field

[0001] The present invention relates to the field of environmental detection, and in particular to a water quality measurement method and device based on surface water circulation. Background Art

[0002] In recent years, ecological environmental protection has received more and more attention. Since the ecological environment involves everyone living on this land, both the country and the people are paying more and more attention to ecological environmental protection. Among them, the protection of water resources is a very important part of environmental protection.

[0003] The detection of water resources usually involves sampling and analysis of the water body to be tested. After the water quality analysis of a single sample is completed, it can only correspond to the water quality information of the sampling location, and it is impossible to extend and further analyze based on the water quality test results of the sample. If it is found that the water quality of the sample is polluted, it is impossible to infer the source of the pollution. If you want to obtain water quality information at more locations, you can only rely on increasing the number of sampling points, that is, increasing the number of samples.

[0049] Figure 1 The structure block diagram of a water quality measurement system based on surface water cycle according to an embodiment of the present invention is shown, the system comprises: a sample acquisition module 101, a sample analysis module 102, a water cycle evolution analysis module 103 and a water quality measurement module 104; wherein,

[0050] The sample acquisition module 101 is used to acquire surface water samples and soil samples from a sampling site, and send the surface water samples and soil samples to the sample analysis module 102 .

[0051] Preferably, the location where the soil sample is collected needs to be a certain distance away from the location where the surface water sample is collected to prevent the soil sample from being too highly correlated with the surface water sample. The specific sampling location is not limited here.

[0052] The sample analysis module 102 is used to perform water quality analysis on surface water samples to obtain initial water quality analysis results, and to perform soil composition analysis on soil samples to obtain initial soil analysis results; compare the initial water quality analysis results with the initial soil analysis results, screen the water quality analysis results based on the comparison results, and process them to obtain a first target water quality analysis result.

[0053] Specifically, the sample analysis module 102 is further used for:

[0054] The analysis method for analyzing surface water samples and soil samples includes at least a purge and trap method.

[0055] Preferably, the sample analysis module 102 is further used for:

[0056] Conduct routine water quality analysis on surface water samples, including at least: pH value, turbidity, conductivity, dissolved oxygen concentration, organic carbon capacity, redox potential, ammonia nitrogen concentration, chemical oxygen demand, sulfur content, lead content, cadmium content, chromium content, mercury content, arsenic content, and selenium content;

[0058] Through the purge and trap method, the samples are subjected to dynamic headspace extraction using inert gas to convert the volatile substances from the liquid phase to the gas phase. After the volatilized substances are adsorbed and captured, they are subjected to gas chromatography analysis to obtain the types of volatile substances in the samples. At the same time, surface water samples and soil samples are routinely analyzed to obtain the conventional physical properties of the samples and the content of various components.

[0059] The water cycle evolution analysis module 103 is used to obtain water cycle information of the sampling area, and determine the source of the surface water sample during the evolution process based on the water cycle evolution process of the sampling area.

[0060] The water quality calculation module 104 is used to calculate a second target water quality analysis result of the source of the surface water sample during the water cycle evolution process based on the first target water quality analysis result.

[0061] The water quality measurement system based on the surface water cycle provided in this embodiment includes: a sample acquisition module, a sample analysis module, a water cycle evolution analysis module and a water quality measurement module; wherein the sample acquisition module is used to obtain surface water samples and soil samples at the sampling site, and send the surface water samples and soil samples to the sample analysis module; the sample analysis module is used to perform water quality analysis on the surface water samples to obtain initial water quality analysis results, and perform soil component analysis on the soil samples to obtain initial soil analysis results; the initial water quality analysis results and the initial soil analysis results are compared, the water quality analysis results are screened according to the comparison results, and the first target water quality analysis results are processed; the water cycle evolution analysis module is used to obtain water cycle information at the sampling site, and based on the water cycle evolution process of the sampling site, determine the source of the surface water samples during the evolution process; the water quality measurement module is used to calculate the second target water quality analysis result of the source of the surface water samples during the water cycle evolution process based on the first target water quality analysis result. By means of the water quality measurement system based on the surface water cycle provided in this embodiment, surface water and soil samples are collected at the collection site, and local surface water analysis results and soil analysis results are obtained through analysis. The influence of the soil at the sampling site on the water quality is excluded through comparison, and the water quality information excluding the influence of the soil is determined. Then, based on the simulated local water cycle evolution process, the possible sources of the surface water samples in the local water cycle evolution process are scientifically determined, and the water quality information of the source is calculated, so that relevant agencies can carry out targeted processing.

[0062] Figure 2 FIG. 4 is a flow chart showing a sample analysis and comparison method according to an embodiment of the present invention. Figure 2 As shown, the method comprises the following steps:

[0063] Step S201, before analyzing the surface water sample and the soil sample, preset the detection items.

[0064] Specifically, the preset detection items include at least preset types of volatile organic compounds.

[0065] Preferably, the surface water samples and soil samples are tested for preset types of volatile organic compounds using a purge and trap method.

[0066] Step S202: Analyze the surface water sample and the soil sample based on the preset detection items, and obtain the initial water quality analysis result and the initial soil analysis result accordingly.

[0067] Step S203, comparing the initial water quality analysis result and the initial soil analysis result to obtain a comparison result; based on the comparison result, determining similar items in the initial water quality analysis result and the initial soil analysis result that have the same or similar analysis results.

[0068] Specifically, since the analysis items for surface water samples and soil samples are the same and are based on preset test items, the analysis items of the initial water quality analysis results and the initial soil analysis results can be matched one to one, and the corresponding items of the two can be unified in units, and then compared to select the items with the same or similar results as similar items. For example, if the content of vinyl chloride in the initial water quality analysis results and the initial soil analysis results is 6 mg / L, then this item will be identified as a similar item.

[0069] Specifically, if the difference between the result of an item in the initial soil analysis results and the result of the corresponding item in the initial water quality analysis results exceeds a preset ratio, it is determined that the item is not a similar item.

[0070] Preferably, the preset ratio may be 20%. For example, if the content of vinyl chloride in the initial water quality analysis results is 6 mg / L, and the content of vinyl chloride in the initial soil analysis results is 4.5 mg / L, then the project is not considered to be a similar project.

[0071] Step S204, deleting the analysis results of similar items from the initial water quality analysis results to obtain a first target water quality analysis result.

[0072] Specifically, based on the comparison results, similar items are screened, and the analysis results of similar items are deleted from the initial water quality analysis results, and the analysis results of the remaining items are used as the first target water quality analysis results.

[0073] According to the above method, the detection of surface water samples and soil samples can be completed according to the same detection items, making the two easy to compare. Through comparison, similar items are screened out according to the above standards, which clearly reflects the impact of local soil on water bodies. According to similar items, the corresponding items in the initial water quality analysis results are deleted, and water quality information based on the impact of water cycle can be scientifically obtained, which is conducive to eliminating interference data and further analyzing the water quality situation in the process of water cycle evolution more accurately.

[0074] Figure 3 A schematic diagram showing a flow chart of a method for determining a water cycle evolution process according to an embodiment of the present invention is shown;

[0075] like Figure 3 As shown, the method comprises the following steps:

[0076] Step S301, obtaining basic geographic information data of the sampling site, as well as meteorological data and hydrological data of the sampling site within a preset time period.

[0077] Step S302, inputting the basic geographic information data of the sampling site, as well as the meteorological data and hydrological data of the sampling site within a preset time period into the hydrological model, simulating the water cycle evolution process of the sampling site within the preset time period.

[0078] Preferably, the changes in surface water evaporation are simulated according to the changes in air temperature, wind speed and relative humidity in the meteorological data within a preset time period, the changes in surface water soil infiltration are simulated through the changes in soil moisture data, and the water cycle evolution process in the area where the sampling site is located within a preset time period is simulated through precipitation data, the direction and velocity of surface water runoff, combined with surface water evaporation, soil infiltration, etc.

[0079] Preferably, the hydrological model may adopt the HYPE (Hydrological Predictions for the Environment) hydrological model.

[0080] Step S303, determining the surface water cycle evolution process of the sampling area according to the simulation results.

[0081] Specifically, based on the simulation results and evolution process of the hydrological model, multiple possible sources of surface water samples at the target time are determined and arranged in order of probability from high to low.

[0082] Preferably, the proportion of water delivered by various sources of water at the sampling location to the sampling site is determined according to the simulation results of the hydrological model and the evolution process, and the possibility is determined according to the proportion of water delivered by each source to the sampling site, and the arrangement is carried out accordingly.

[0083] Specifically, a preset number of possible sources are selected from the arrangement results in order of arrangement as target sources of surface water samples.

[0084] Preferably, a possibility threshold is set, and the possible sources in the list of possible sources with a probability higher than the possibility threshold are determined as target sources. For example, if the possibility threshold is set to 10%, and there are two possible sources in the possibility list with a probability higher than 10%, then these two sources are determined as target sources.

[0085] According to the above method, the hydrological model can be used to completely simulate the water cycle evolution process of the sampling area within a preset time period. Based on this evolution process, the most likely source of the surface water sample can be scientifically determined, which is convenient for operators to further explore the water quality of the source and narrow the possible source range of pollution when pollution exists.

[0086] Figure 4 A schematic flow chart of a method for calculating water quality at a target source according to an embodiment of the present invention is shown;

[0087] like Figure 4 As shown, the method comprises the following steps:

[0088] Step S401, based on the first target water quality analysis result and the simulation result of the water cycle evolution process within a preset time period, the second target water quality analysis results corresponding to different target source areas are respectively calculated.

[0089] Preferably, the second target water quality analysis result corresponding to each target source is calculated based on the corresponding possibilities of different target sources (i.e., the proportion of water delivered to the sampling site) and combined with the results of each detection item.

[0090] For example, the water volume obtained at the sampling site is provided by River A for 80% and by River B for 20%, that is, the corresponding upstream locations of River A and River B are the target sources. If the content of vinyl chloride in the surface water sample is 5 mg / L, the corresponding content of vinyl chloride when River A or River B is the target source can be reversely calculated, and then the second target water quality analysis result can be determined.

[0091] Step S402, displaying the second target water quality analysis results corresponding to each target source to the operator.

[0092] Preferably, the obtained second target water quality analysis result is compared with the corresponding water quality standard, and the items exceeding the standard are prompted to the operator.

[0093] According to the above method, the water quality of possible sources can be reversely calculated according to the process of water cycle evolution and the water quality conditions of the sampling site, and the operator can be automatically prompted when the water quality does not meet the standard. This helps the operator to quickly obtain information on water quality exceeding the standard and narrow the possible scope of pollution sources, so that the local area does not need to conduct excessive water sampling to more scientifically understand the water quality information during the water cycle evolution, thereby reducing the overall detection cost.

[0101] Comparing the initial water quality analysis results with the initial soil analysis results to obtain a comparison result; based on the comparison result, determining similar items in the initial water quality analysis results and the initial soil analysis results that have the same or similar analysis results;

[0102] The analysis results of similar items are deleted from the initial water quality analysis results to obtain the first target water quality analysis results.

[0103] Preferably, a conventional water quality analysis is performed on the surface water sample, including at least: pH value, turbidity, conductivity, dissolved oxygen concentration, organic carbon capacity, redox potential, ammonia nitrogen concentration, chemical oxygen demand, sulfur content, lead content, cadmium content, chromium content, mercury content, arsenic content, and selenium content;

[0104] Conduct routine soil analysis on soil samples, including at least: soil organic matter content, potassium content, phosphorus content, nitrogen content, lead content, cadmium content, chromium content, mercury content, arsenic content, selenium content, pH value, soil cation exchange capacity, and electrical conductivity.

[0105] Step S503, obtaining the water cycle information of the sampling ground, and determining the source of the surface water sample during the evolution process based on the water cycle evolution process of the sampling ground.

[0106] Specifically, basic geographic information data of the sampling site, as well as meteorological data and hydrological data of the sampling site within a preset time period are obtained;

[0107] Input the basic geographic information data of the sampling site, as well as the meteorological data and hydrological data of the sampling site within a preset time period into the hydrological model to simulate the water cycle evolution process of the sampling site within the preset time period;

[0108] The surface water cycle evolution process of the sampling area is determined based on the simulation results.

[0109] Preferably, based on the simulation results and evolution process of the hydrological model, multiple possible sources of the surface water samples at the target time are determined and arranged in order of probability from high to low;

[0110] A preset number of possible sources are selected from the arrangement results in order of arrangement as target sources of surface water samples.

[0111] Step S504, calculating a second target water quality analysis result of the source of the surface water sample during the water cycle evolution process based on the first target water quality analysis result.

[0112] Specifically, based on the first target water quality analysis results and the simulation results of the water cycle evolution process within a preset time period, the second target water quality analysis results corresponding to different target source areas are calculated respectively;

[0113] The second target water quality analysis results corresponding to each target source are displayed to the operator.

By using the water quality measurement method based on surface water cycle provided by the present embodiment, surface water and soil samples are collected at the collection site, and local surface water analysis results and soil analysis results are obtained through analysis. The influence of the soil at the sampling site on water quality is excluded by comparison, and water quality information excluding the influence of soil is determined. Then, based on the simulated local water cycle evolution process, the possible source of the surface water sample in the local water cycle evolution process is scientifically determined, and the water quality information of the source is calculated. The obtained water quality information helps relevant personnel to determine the possible source of water pollution, and further determine the problems affecting water quality at the possible source, so that relevant agencies can deal with them in a targeted manner, which greatly improves the scientificity and pertinence of water pollution source judgment, improves the work efficiency when determining the pollution source, is beneficial to the overall protection of local water resources environment, and improves the use scenarios and application scope of single-location water quality detection, so that the local area does not need to conduct excessive water sampling to scientifically understand the water quality information in the water cycle evolution process, thereby reducing the overall detection cost.
