Abstract

The invention discloses a portable rapid water quality detector and a water quality detection method, and belongs to the technical field of water quality analysis and detection. The portable rapid water quality detector comprises an LED light source and a detection assembly, wherein the detection assembly comprises a four-light-transmitting cuvette, an LED light source intensity detection module,an ultraviolet absorption light intensity detection module and a fluorescence light intensity detection module; the LED light source is used for emitting ultraviolet light to the four-light-transmitting cuvette; the ultraviolet absorption light intensity detection module is used for detecting the light intensity of ultraviolet light which is not absorbed after passing through the four-light-transmitting cuvette; the fluorescence light intensity detection module is used for detecting the light intensity of the fluorescence light which is excited by a to-be-detected liquid passing through the four-light-transmitting cuvette; and the LED light source intensity detection module is arranged between the LED light source and the corresponding light transmission surface and is used for detecting the light intensity of ultraviolet light emitted by the LED light source in real time. The portable rapid water quality detector can be used after startup, and the water quality detection by the devicecan more accurately reflect the substance composition contained in the to-be-detected liquid.

Description

technical field [0001] The invention belongs to the technical field of water quality analysis and detection, and in particular relates to a portable rapid water quality detector and a water quality detection method, which can quickly detect natural organic matter and aromatic synthetic compounds dissolved in water. Background technique [0002] Dissolved organic matter, including macromolecular polysaccharides and protein substances, medium molecular weight humic substances, fulvic acid and building block small molecular substances, widely exists in various natural water bodies, sewage and drinking water. The methods for analyzing and detecting the concentration level of dissolved organic matter mainly include chemical method and spectroscopic method. Indexes such as chemical oxygen demand and total organic carbon are chemical indicators reflecting the concentration of dissolved organic matter. The total organic carbon concentration of dissolved organic matter in urban tap w...
