<p><P>PROBLEM TO BE SOLVED: To provide a method for solving the problem that running cost is high, maintenance is difficult, or the like, in the treatment of organic waste water. <P>SOLUTION: In this treating method, bacilli belonging to the family Bacillaceae are made to be dominant in a biological treatment tank 2 and thereby there is no need to continue the purchase of nutrients for activating the bacilli. Further, microorganismic groups except for the Bacillaceae bacilli in sludge are selectively sterilized and by utilizing them as nutrients in the biological treatment tank 2, the Bacillaceae bacilli can be propagated/be made to be dominant without newly establishing a culture tank to culture the bacilli. Thus, the quality of treated water is improved, an amount of excess sludge 6 is decreased, malodors are suppressed and further maintenance can be facilitated and cost reduction can be attained. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
