<p><P>PROBLEM TO BE SOLVED: To provide a waste water treatment method which dispenses with a culture tank for germinating and growing Bacillus genus bacteria and can stably provides treated water even when a load more than the capacity of waste water treatment equipment is applied to the waste water treatment equipment and, further, a hardly degradable substance or a toxic substance for microorganism flows into the equipment, by utilizing synergistic effect between saponin and Bacillus genus bacteria even without adding a specific nutrient source for germinating and growing Bacillus genus bacteria. <P>SOLUTION: The waste water treatment method is characterized in that, upon biological treatment of waste water, the saponin and Bacillus genus bacteria are added during the treating process. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
