The invention provides an 
algae removal method and a movable 
algae removal platform suitable for a river channel type 
water body. The 
algae removal method and the movable algae removal platform suitable for the river channel type 
water body utilize a ship body as a carrier, adopt an ultrasonic algae removal instrument, a 
microfiltration machine, a self-suction type spiral stirring 
aeration machine and a rotary type algae salvage 
machine for matching, achieves ultrasonic removal, mechanical salvage, algae-water separation, and functional combination of 
water body oxygen enrichment and air floatation to restrain the growth of the algae in water, the 
irradiation frequency of ultrasonic 
waves is A which equals to 20-50 kHz, the 
irradiation distance is B which equals to 0.5m, and the 
irradiation time is C which equals to 5min. According to the algae removal method and the movable algae removal platform suitable for the river channel type water body, the algae 
body cell air bags and 
cell ectocrine are affected to further affect the agglomeration effect of the algae in water so that the removal of the algae is achieved. Compared with a stationary type ultrasonic algae removal method, rapid and accurate function can be carried out on the entire research 
water area. The movable algae removal platform eliminates the heavy 
workload of algae salvage for workers when a water bloom occurs, causes smaller economic loss compared with that caused by 
eutrophication of the water body, is suitable for 
water quality characteristics of secondary rivers in the 
Three Gorges Reservoir Region, and has a good demonstration effect.
