<p>[PROBLEMS] To provide a method for completely eliminating sludge accumulated on the bottom of water in a fishery, or the like. [MEANS FOR SOLVING PROBLEMS] (1) A method for eliminating sludge accumulated on the bottom by using a bottom sludge treatment facility comprising a micro air generation system consisting only of a micro air generator or of a micro air generator and a compressor, a means for supplying micro air from the micro air generation system to an aerator, a micro air aerator being installed on the bottom of water, and a bottom sludge cover. (2) A method for eliminating sludge accumulated on the bottom as described in (1) where the micro air aerator is an air diffusing pipe. (3) A method for eliminating sludge accumulated on the bottom as described in (1) where the micro air aerator has a containing frame being installed on the bottom of water and filled with fully ripened compost, and an air lift hood connected with a float floating on the water surface and provided, at the uppermost part thereof, with a back wash lid capable of being opened/closed by remote control. (4) A method for eliminating mud accumulated on the bottom as described in (3) where the micro air generation system, a solar panel for power supply, and a charger/battery are mounted on another float separate from the above float.</p> |
