A fluid path device of a water quality on-line detector and a detection method are provided. The device comprises a colorimetric module, and the colorimetric module is provided with a water sample input line and a waste liquid output line. A reagent injecting pipe is disposed on the water sample input line, and a reagent injector is connected with the injecting end of the reagent injecting pipe. The reagent injector injects the reagent into the water sample input line intermittently, full dissolution is performed, and the water quality is detected by the colorimetric module. The fluid path device of the water quality on-line detector and the detection method can perform the detection in a very fine pipeline, and has no need of a buffer vessel, so that the water sample and reagent can be used as less as possible when the liquid reaction colorimetric detection performs, and the quantity of the waste liquid is relatively small. Moreover, the pipeline maintenance is simple, the only need is cleaning or changing the pipeline in normal maintenance, the cost is low, and the operation is simple.
Description
technical field [0001] The invention relates to the technical field of online water quality detection, in particular to a liquid circuit device and a detection method of an online water quality detector. Background technique [0002] At present, the existing photometric online detectors on the market have a relatively complicated liquid circuit structure. During the detection, quantitative chemical reagents and water samples need to be added to the cuvette, stirred and mixed evenly, and then the color is developed, and then the substance is determined by colorimetry. concentration. Colorimetry after continuous sample injection or colorimetry after reaction in the cuvette consumes a lot of reagents during the test, resulting in waste of cost, and at the same time produces a large amount of waste liquid, which is not environmentally friendly. In addition, although the instruments of this type of liquid circuit can be free of maintenance for a certain period of time after cali...
