<p><P>PROBLEM TO BE SOLVED: To provide a method for treating waste water, by which a filthy component can satisfactorily be removed easily from the waste water to be discharged when laver is manufactured. <P>SOLUTION: This method for treating waste water comprises a precipitation step to remove suspended matter in the waste water discharged from a laver manufacturing step, a step to add an aspergillus to the waste water from which the suspended matter is removed to some degree and an aeration step to supply oxygen to the aspergillus-added waste water. At the aeration step, the aspergillus is propagated actively by taking a large quantity of air in the waste water by using an ejector so that the filthy component contained in the waste water is removed. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
