ABSTRACT:
A waste water treatment apparatus is provided which can treat a high-concentration waste water containing persistent chemical substances including nitrogen and surfactant simultaneously with small amount of exhaust gases and is yet simple in construction. The apparatus has a first bioreactor having a lower portion including an inflow pipe for admission of waste water to be treated and aeration means, and an upper portion packed with vinylidene chloride fillers; a second bioreactor including a filler-packed portion packed with charcoal and calcium carbonate fillers; and an exhaust gas introduction diffuser for directing exhaust gases generated in an uppermost portion of the first bioreactor into the filler-packed portion. The water under treatment is anaerobically treated in the lower portion and is subjected to aerobic treatment and also to anaerobic treatment in the upper portion. Further, in the second bioreactor, the water under treatment is again aerobically treated and, at the same time, the exhaust gases from the first bioreactor are also aerobically treated.
