ABSTRACT:
A method for improving the quality of bottom and water in water areas where sludge is deposited on the bottom. In a sample water area, lime, activated sludge and anaerobic sludge, diatomaceous earth or zeolite, and photosynthesis bacteria solution are spread. Before spreading, the photosynthesis bacteria solution is infiltrated into at least either one of the activated sludge and anaerobic sludge, and the diatomaceous earth or zeolite. For the above method, four kinds of the above agents are prepared in a predetermined proportion, and they are separately packed.
