ABSTRACT:
To allow compact and simple design of a water treatment system capable of denitrification, an anaerobic treatment vessel 3 is provided downstream of an aerobic treatment vessel 2, and a filter layer 5 having a large number of carriers for microbes filled therein is formed in the anaerobic treatment vessel so that sulfur contents may be reduced by sulfate reducing microbes bred in the filter layer and the nitrate nitrogen is gasified by sulfur denitrification microbes with the aid of the sulfides thus obtained. In particular, the carriers preferably comprise a floating filter material in the form of plastic foam blocks that can float in the water.
