<p><P>PROBLEM TO BE SOLVED: To provide a waste water treatment method which improves waste water treatment capability since activated sludge microbial cells are stabilized even when a concentrated waste water and dilute drain are treated and which makes the microbial cells easily acclimatizable even for the concentrated waste liquid containing much hardly decomposable pollutant. <P>SOLUTION: The waste water treatment method for treating the concentrated waste liquid and the dilute drain is provided with an activated sludge treatment apparatus (AR) for treating the concentrated waste liquid (A) and an activated sludge treatment apparatus (BR) for treating the dilute drain (B). The drain treatment method comprises a step of subjecting the concentrated waste liquid to an anaerobic/aerobic treatment in the apparatus (AR) and a step of subjecting the concentrated waste liquid after the anaerobic/aerobic treatment to the anaerobic/aerobic treatment together with the dilute drain in the apparatus (BR) without subjecting the concentrated waste liquid to solid-liquid separation treatment. <P>COPYRIGHT: (C)2004,JPO</p> |
