CONTAMINANT DECOMPOSING APPARATUS OF LAKES AND MARSHES USING FEEBLE ULTRASONIC WAVES

摘要

PROBLEM TO BE SOLVED: To decompose a contaminant of lakes and marshes by accelerating the propagation of microorganisms by feeble ultrasonic waves. SOLUTION: A solar cell 3 is mounted on the frame member 2 assembled on a raft 1 and ultrasonic oscillators 4 are arranged within the frame member 2 to receive the supply of power from the solar cell 3 and a large number of large metal plates 5 are suspended from the frame member 2 and ultrasonic vibrators 6 are respectively mounted on the metal plates 5 to be connected to one terminals of the ultrasonic oscillators 4 and the other terminals of the ultrasonic oscillators are connected to the large metal plates as common terminals. Power is always applied to the ultrasonic vibrators from the solar cell and ultrasonic oscillator applies the oscillation output so that feeble ultrasonic waves of one watt or less per radiation area of 1cm<2> are generated from the ultrasonic vibrators.
