<p>PURPOSE:To increase the discharge of a Ca ion and to positively decompose and reduce sludge blocked from water by a lime film, by sprinkling lime, activat ed sludge, anaerobic sludge,. diatomaceous earth or zeolite and a bacteria cell soln. of photosynthetic bacteria over an objective water area. CONSTITUTION:Activated sludge and anaerobic sludge (TB) are sprinkled over an objective water area and lime (UT) is subsequently sprinkled over the water area and, further, TB, diatomaceous earth or zeolite (CG) and a bacterial cell soln., (PB) of photosynthetic bacteria are sprinkled over the water area. By sprinkling UT, TB, CG and PB over a closed water area where sludge is accumulated on the bottom part, the pollutants suspended in the water area are rapidly sedimented and hydrogen sulfide in water and sludge is decomposed as rapid as possible and sludge is decomposed and reduced and the Ca ion in water is effectively discharged to improve a bottom material and water quality.</p> |
