An unmanned surface vessel (USV)
system for
algae control, based on 222nm mercury-free far-
ultraviolet lamps and their combined processes, belongs to the field of
water environment management technology. Addressing the issues of
delayed response to cyanobacterial blooms in water sources, limited treatment capacity of existing mobile devices with closed reactors, and single-
parameter control, the
system uses an USV as its platform, integrating a 222nm mercury-free far-
ultraviolet lamp matrix, an automatic dosing unit, and an intelligent sensing and
adaptive control module. The mercury-free far-
ultraviolet lamp matrix adopts an
open structure, directly immersed in the
water body for large-area in-situ
irradiation; the intelligent sensing and
adaptive control module collects multi-dimensional parameters such as algal density,
chlorophyll a, and algal toxins in real time; the central
control system incorporates a built-in PID multi-parameter
coupling model to dynamically adjust the
irradiation intensity and dosing dosage, using algal
toxin concentration as the feedback endpoint to form a closed-
loop control. It possesses advantages such as wide-area in-situ coverage, high efficiency, mercury-free
environmental protection, and on-demand intelligent energy saving, making it suitable for routine operation and maintenance and
emergency response in lake and reservoir-type water sources.
