Abstract
A regional water purifier collects blue green algae continuously by using a water flow produced by the operation of a water flow generator, and continuously and efficiently processes the algae to make it inactive by irradiating ultrasonic waves thereon. Thus, regional water purification is performed efficiently at a far lower cost than the conventional method through the blue green algae processing. The purifier includes a blue green algae processing duct , which is disposed under water where blue green algae breed in large quantities, and has an ultrasonic wave transmitter therein for transmitting ultrasonic waves to process the blue green algae with the ultrasonic waves. Both ends of the duct are open, and a water flow generator produces a suction flow for sucking water containing blue green algae into the blue green algae. processing duct from a first end and a discharge flow for discharging the water from the second end
