The invention discloses a quick detecting device and method of toxic and harmful organic chemical pollutants in a water body. The quick detecting device and method are used for meeting the demands of safety precaution of drinking water of our country and quick online detection of the toxic and harmful organic chemical pollutants in the water body and overcoming the defects of the existing detecting measures. A narrow-band LED (Light Emitting Diode) servers as an excitation light source, an echelle grating serves as a fluorescence optical splitter, and a gating ICCD (Intensified Charge Coupled Device) serves as a fluorescence detector for researching the quick detecting method and system of the toxic and harmful organic chemical pollutants in the environmental water body of our country and developing a quick online detecting model machine with high sensitivity on the toxic and harmful organic chemical pollutants in the water body, the toxic and harmful organic chemical pollutants in the water body are quickly and effectively measured in a laboratory, the manual sampling is avoided, the structure of an instrument is simple, and the utilization rate of the excitation light source is high and the detecting speed is high, so that the quick detecting device and method are suitable for online detecting and early-warning on the trace toxic and harmful organic chemical pollutants in the natural water body and online emission reduction monitoring on industrial waste water so as to reflect the pollution condition of the water body in real time.
Description
technical field [0001] The invention relates to the field of chemical pollutant detection systems, in particular to a rapid detection device and detection method for toxic organic chemical pollutants in water bodies. Background technique [0002] The pollution caused by excessive discharge of industrial wastewater, serious lack of domestic sewage treatment facilities, and untreated farmland drainage directly affects the safety of drinking water quality and seriously endangers human health. Among them, chemical pollutants are the most typical, and most of them are carcinogenic, teratogenic, and mutagenic. It is estimated that the tumors related to chemical pollutants account for more than 90%. [0003] Europe, the United States, Japan and other countries have conducted a lot of research on water toxic organic chemical pollutants (including oil, phenols, polycyclic aromatic hydrocarbons, pesticides, etc.), and formulated a series of control standards and regulations. The rese...
