Removal method of marine sediments using micro-air bubbles
The invention relates to a removal method of marine sediments using micro-air bubbles. An area in need of operation is provided with a slit curtain so that sediments and tiny clay particles are prevented from flowing to the outside, ultrasonic waves are employed to break tiny clay particles generated during the dredging of the sediments to equal tiny particles, natural coagulant is put into the particles, floc is formed, micro-air bubbles are injected so that condensed floc floats on the surface of seawater, and the sediments are eliminated. According to the removal method, turbidity inducing substances can be permanently and rapidly eliminated, compared with the conventional dredging method, the time can be obviously shortened, the surrounding eco-environment is almost not influenced, the problem of pollution sediments can be dealt with, and the quality of continuous production of aquatic products is excellent.
