Mixed chlorine, micro-nano aeration and ultraviolet LED coupled raw water algae removal and smell suppression system

The invention discloses a mixed chlorine, micro-nano aeration and ultraviolet LED coupled raw water algae removal and odor suppression system. The system comprises an ammonia nitrogen-chlorophyll a online detection unit, a chlorination reaction unit, a total residual chlorine online detection unit, a micro-nano aeration unit, a front intelligent control unit, a sodium hypochlorite adding device, a rear intelligent control unit and an ultraviolet LED unit. According to the invention, mixed-state chlorine, specific-wavelength ultraviolet and micro-nano aeration technologies are coupled, and the coupling effect of hydroxyl free radicals, active chlorine free radicals and ultraviolet photon radiation is realized by intelligently regulating and controlling the mixed-state chlorine and the specific-wavelength ultraviolet LED with proper proportions and doses and by virtue of the hydraulic regulation and ammonia nitrogen removal effects of micro-nano aeration, so that the aim of purifying the ammonia nitrogen is ful
