Fig. 1 is a schematic block diagram of a water quality detection analyzer according to an embodiment of the present invention.
As shown in fig. 1, a water quality detection analyzer 100 according to an embodiment of the present invention includes: a three-dimensional fluorescence detection module 110, a biotoxicity detection module 120, and a control module 130.
The three-dimensional fluorescence detection module 110 is configured to obtain three-dimensional fluorescence spectrum information of a water sample to be detected. The biotoxicity detection module 120 is used for acquiring biotoxicity information in a water sample to be detected.

It should be noted that the three-dimensional fluorescence detection module 110 in the embodiment of the present invention is a miniaturized high-precision three-dimensional fluorescence scanning detection component, so as to meet the requirements of miniaturization, portability and field performance of the water quality detection analyzer.
Specifically, when a water sample in a certain area needs to be detected, the water sample to be detected in the area is obtained, the water sample to be detected is placed at the sampling position of the water quality detection analyzer, and the water quality detection analyzer can complete sampling and data acquisition. Specifically, the three-dimensional fluorescence detection module 110 is used to obtain three-dimensional fluorescence spectrum information of the water sample to be detected, and the biotoxicity detection module 120 is used to obtain biotoxicity information of the water sample to be detected. After obtaining the three-dimensional fluorescence spectrum information of the water sample to be detected and the biological toxicity information in the water sample to be detected, the control module 130 detects whether the water sample is polluted according to the three-dimensional fluorescence spectrum information of the water sample to be detected and the biological toxicity information in the water sample to be detected, and analyzes whether the pollution source of the water sample is from which enterprise or industry.
In an embodiment of the present invention, the control module 130 determines the water sample pollution and analyzes the pollution source of the water sample when any one of the three-dimensional fluorescence spectrum information of the water sample to be detected and the biological toxicity information of the water sample to be detected exceeds a corresponding preset value.
For example, the control module 130 compares the fluorescence spectrum information of each dimension in the three-dimensional fluorescence spectrum information, and determines that the water sample is polluted if any one-dimensional fluorescence spectrum information in the three-dimensional fluorescence spectrum information exceeds a corresponding preset value; the control module 130 judges the biological toxicity information, if the biological toxicity information exceeds a corresponding preset value, the water sample pollution is determined, and the water sample pollution is compared with the standard toxic substance HgCl2 or phenol in the region to which the water sample pollution belongs, so that a corresponding toxicity grade can be obtained; when the three-dimensional fluorescence spectrum information of the water sample to be detected and the biological toxicity information in the water sample to be detected do not exceed the corresponding preset values, the control module 130 determines that the water sample is not polluted.
After the water sample is polluted, the control module 130 analyzes the pollution source of the water sample, and specifically, the diagnosis of the pollution source of the water sample can be performed in an online mode or an offline mode, and the name and the similarity of the pollution source with the closest similarity are given. For example, when a clean water body (such as a water body in class III or a water body better than class III) is polluted, if the water quality detection analyzer determines that the similarity between a water sample to be detected and a certain pollution source reaches more than 90%, the water sample to be detected can be considered to be polluted by the pollution source; if the water quality detection analyzer judges that the similarity between the water sample to be detected and a certain pollution source reaches more than 80%, the water sample to be detected can be considered to be related to the pollution source, but other pollution sources can exist at the same time.
Therefore, the water quality detection analyzer can quickly and accurately detect whether the water sample is polluted or not and analyze the pollution source of the water sample.

Further, in order to facilitate the user to obtain the water pollution condition in time, as shown in fig. 4, the water quality detecting analyzer further includes: an early warning analysis module 150. The early warning analysis module 150 is connected to the control module 130, and the early warning analysis module 150 is configured to send out early warning information when the water sample is polluted. The early warning analysis module 150 may be an acoustic and/or optical early warning analysis module, and may be specifically set according to actual needs. For example, when the water quality detection analyzer operates in an online mode, the water quality detection analyzer can judge according to the signal intensity of detected pollutants, and if the signal intensity is higher than the maximum value of the early warning interval or lower than the minimum value of the early warning interval, the red light is lighted at the position of the corresponding pollution intensity of the water quality detection analyzer, and an alarm sound is given out to remind a user of paying attention.

The sample to be measured in the sample cell 112 generates fluorescence under the excitation of the excitation light, and is collected by another lens in the direction perpendicular to the excitation light and coupled into the spectrometer 113, so as to detect the signal of the three-dimensional fluorescence spectrum. The user can control the monochromator 1112 through a control device such as a computer to scan the wavelength of the excitation light, and measure one spectrum using the spectrometer 113 every time one wavelength is output, thereby realizing the measurement of the three-dimensional fluorescence spectrum.
