Algae detection system based on planar electrode array

Abstract

The invention provides an algae detection system based on a planar electrode array. The algae detection system comprises a multi-electrode sensor array and a micro-pipeline, the multi-electrode sensor array comprises a plurality of groups of electrodes, and each group of electrodes consists of interdigital electrodes with unequal widths and intervals; the interdigital electrodes are arranged symmetrically and asymmetrically, are packaged in the water flow channel and are used for measuring the capacitance of a water body; the micro-pipeline comprises a water inlet, a water flow channel and a water outlet; algae water enters the water flow channel through the water inlet, the number of algae is detected through the multi-electrode sensor array, and finally the algae water flows out through the water outlet. The beneficial effects of the algae detection system are that the algae detection system can provide a real-time detection result, also can achieve the miniaturization and low power consumption of the sensor, reduce the manufacturing cost, and effectively supplement a conventional detection means.

Description

technical field [0001] The invention relates to the field of water quality algae detection, in particular to an algae detection system based on a planar electrode array. Background technique [0002] Algae blooms caused by the overgrowth of various algae represented by cyanobacteria are one of the most important threats to my country's water ecological security. Common cyanobacteria detection methods at this stage include laboratory analysis, remote sensing detection, and in vivo fluorescence analysis. However, from the perspective of the effect of algae bloom prevention and control, the existing methods still have problems such as long detection cycle, insufficient measurement accuracy, and high cost. Contents of the invention [0003] In view of this, facing the actual needs in the prevention and control of water blooms, and aiming at the biological characteristics of algae itself and the concentration differences in different water bloom stages, the present invention pr...
