<p>PURPOSE:To accelerate the granulation of methane fermentation bacteria and to shorten the rising period of a reaction tank operated only by load lower than planned load in an anaerobic water treatment apparatus biochemically treating waste water using anaerobic bacteria. CONSTITUTION:A flocculant adding apparatus 10 adding a flocculant for flocculating the seed sludge charged in a treated water tank 5 at the rising time of an apparatus and a static mixer 12 mixing seed sludge and the flocculant are provided to the circulating pipeline from the treated water tank 5 to a reaction tank 3.</p> |
