Abstract
According to a waste water treatment method and apparatus of the present invention, a permeable sheet,is fed into a treatment tank,in which a stream is formed. The waste water, which flows downstream, is caused to pass through the permeable sheet,, while the permeable sheet,travels in the treatment tank,so as to traverse the surface of the waste water on a downstream side in the flowing direction of the waste water. Therefore, not only the sludge in the waste water but also the oily substances floating in the waste water can be collected and removed because they cling to the permeable sheet,and are gathered by it. As a result, a waste water treatment tank,and the like can be maintained in a usable state for a long time. In addition, there can be obtained a treated water to which microbial treatment can be applied.
