Anaerobic waste water treatment device

Abstract

Abstract PURPOSE:To enable the anaerobic treatment of the solid org. matter without previously separating and removing said matter from raw water for treatment and to reduce the size of a treatment device by providing a downward counter current type anaerobic treatment tank having anaerobic filter beds in which the solid org. matter in the supplied raw water for treatment settles. CONSTITUTION:The raw water A for treatment contg. the solid org. matter is supplied to a 1st anaerobic treatment tank 10 of the downward counter current type and the solid org. matter is settled in the anaerobic filter bed 16 of this treatment tank 10 and is separated from the raw water A. Only the separated solid org. matter is anaerobically treated in a restrained state in a sludge tank 28. The primarily treated water B from which the solid org. matter is separated in such a manner is supplied from the lower part of the 1st anaerobic treatment tank 10 via a communicating path 18 positioned above the sludge tank 28 to the lower side of an upward counter current type 2nd anaerobic treatment tank 12. The primarily treated water is anaerobically treated in this anaerobic filter bed 20.
