Embodiment Construction

[0020] In order to better understand the contents of the present invention, an example is given here.

[0021] The invention discloses a high-flux array water quality sensor, figure 1 It is a composition diagram of the high-throughput array water quality sensor disclosed in the present invention, which specifically includes an N-row and N-column colorimetric cell array, an N-row and N-column receiving optical fiber array, and an N-row and N-column LED light source array. The basic units at the same row and the same column in each of the above three arrays correspond to each other in position distribution, so as to ensure that the light emitted by the LED light source at a certain row and a certain column in the N row and N column LED light source array passes through N rows The corresponding colorimetric cuvettes in the same row and column in the N-column colorimetric cell array are received by the corresponding receiving optical fibers in the same row and column in the N-row ...

Abstract

The invention discloses a high-throughput array type water quality sensor, and the sensor specifically comprises an N-row and N-column colorimetric pool array, an N-row and N-column receiving optical fiber array and an N-row and N-column LED light source array, and the N-row and N-column colorimetric pool array is used for pre-loading a chemical reagent which generates a chromogenic reaction with a water sample. Basic units at the same row and column in the three arrays correspond to one another in position, and the system further comprises an optical fiber bundle, a collecting lens, a photodiode, a transconductance amplifier, an A/D converter and a data acquisition system; the optical fiber bundle is connected with the collecting lens, the collecting lens is connected with the photodiode, the photodiode is connected with the transconductance amplifier, the transconductance amplifier is connected with the A/D converter, the A/D converter is connected with the data acquisition system, and the data acquisition system is connected with the LED scanning driving controller. The sensor is high in detection speed and short in detection time, greatly overcomes the defect that an existing single-channel single-parameter colorimetric sensing method is time-consuming and labor-consuming, and is suitable for rapid on-site detection of water quality of a large sample.

Description

technical field [0001] The invention belongs to the technical field of water quality monitoring, in particular to a high-flux array water quality sensor. Background technique [0002] Drinking water safety is a global strategic issue. In recent years, a large amount of industrial pollution and wastewater discharge of pesticides and veterinary drugs have resulted in a large amount of residues of heavy pollutants such as benzene series, phenols, and heavy metals in surface water. Although the waterworks have carried out strict screening, nitrification, disinfection and other control treatments on the water quality of the water sources, drinking water safety accidents have not been eliminated, which has greatly threatened social and economic development and people's healthy life. [0003] Water quality testing and monitoring is an important means to prevent drinking water safety accidents. Water quality detection and monitoring need to use water quality sensors to complete.
