摘要： A method and a system for pollutant identifying and early warning based on cluster analysis include steps of: installing multiple high-definition cameras on a river or a sluice dam, capturing pollutant images in front of the sluice dam at certain intervals, and transmitting the pollutant images captured by the high-definition cameras to a computer; reading the pollutant images transmitted to the computer; extracting a main pollutant color in the pollutant images through cluster analysis; calculating a difference between the main pollutant color and RGB data in a pollutant color gamut database, and setting an aberration threshold to identify the pollutant color; performing scale conversion with two sets of common point image pixel coordinates and actual plane coordinates to calculate a current pollutant area; and judging whether a polluted area exceeds a critical value according to a preset pollutant area threshold, thereby realizing early warning.

摘要： An emergency treatment device for algal blooms in reservoir tributaries and bays includes a hull, an automatic detection unit provided on the hull, an algae collection-separation unit, an ultrasonic algae removal unit, a micro-current electrolytic algae suppression unit, an algaecide adding unit, a power unit and a control unit. The automatic detection unit, the algae collection-separation unit, the ultrasonic algae removal unit, the micro-current electrolytic algae suppression unit, the algaecide adding unit and the power unit are connected with the control unit. The algae collection-separation unit is used for suction and ex-situ treatment of high-density algae on a surface of the water body. The ultrasonic algae removal unit, the micro-current electrolytic algae suppression unit and the algaecide adding unit are used for in-situ treatment of algae in the water body.
