<p>PURPOSE: A microorganism stabilizer for biological sewage/wastewater treatment is provided to prevent bulking in activated sludge process and improve metabolism of microorganism. CONSTITUTION: Magnetite is crushed to 40-60 micrometer. And phyllite is crushed to 40-60 micrometer. Magnetized magnetite and phyllite are mixed such that the mixture contains Fe3O4 5-15 wt.%. Peat contained fulvic acid is mixed with HCl or H2SO4, for separating fulvic acid from peat. The mixture of magnetite, phyllite and separated fulvic acid are mixed in a ratio of 0.8-1.3 (ratio of organic/inorganic materials). And above mixture is aged for 30 days or more.</p> |
