<p><P>PROBLEM TO BE SOLVED: To provide an anaerobic wastewater treatment apparatus capable of an effective and stable treatment suppressing the outflow of granules of anaerobic microorganisms. <P>SOLUTION: The wastewater is introduced into a reactor from beneath for a reducing and decomposing treatment of the organic matters contained by the wastewater by making the wastewater flow through an anaerobic microorganism layer. After the treatment, treated gas is discharged via an exhaust port while treated water, interrupted by an outflow preventing plate allowing the granule of the anaerobic microorganisms suspended in it to precipitate, flows out over a flooding weir, thus preventing the outflow of the granule of the anaerobic microorganisms. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
