<p><P>PROBLEM TO BE SOLVED: To reduce a cost of a water cleaning structure and to provide the inexpensive water cleaning structure by simplification of a system and use of net-like body members, such as overused fishing nets. <P>SOLUTION: The water cleaning structure 12 has an upper frame 14, a lower frame 16 and a plurality of water cleaning implements 18 spanned between the upper frame 14 and the lower frame 16. The implements 18 comprise rod-like supports 20, a plurality of locking implements 22 projected on the outer peripheral surfaces of the supports 20 and members for microorganism propagation wound around the supports 20. The members for microorganism propagation comprise the net-like body members 24, such as the overused fishing nets, to be transported to an incineration plant and to be disposed by incineration. The net-like body members 24, such as the fishing nets are easily depositable with the microorganisms and are adequate as the members for microorganism propagation. <P>COPYRIGHT: (C)2003,JPO</p> |
