<p>PROBLEM TO BE SOLVED: To provide a microorganism material having high the biological decomposition capacity of org. matter in org. waste and capable of reducing or removing a malodor generated from org. matter. SOLUTION: An inorg. soln. prepared by dissolving 42g of managnese chloride hydrate, 455g of iron chloride hydrate, 393g of magnesium sulfate hydrate and 434g of calcium chloride hydrade in 2 m<3> of tap water, 5 l of a humic soln. prepared by dissolving 1.5 kg of humic acid and 100 g of sodium hydroxide in 100 of tap water and 200 l of leaf mould are introduced into an aeration tank 13 and aerated for about 20 hr by 200 l/min of air while the humic soln. is added little by little and, thereafter, excretion of a milk cow is intermittently added to the aerated soln. by about 1 m<3> /day in a steady state to repeat aeration operation until org. matter is decomposed or stabilized. By this method, a soil microorganism culture soln., the supernatant soln. or a precipitate is formed as a microorganism material.</p> |
