Abstract

PURPOSE: To carry out the biological treatment and separation of suspension in a single vessel at the same time, by flowing downward the waste water in treating vessel floated small solid particles having lower specific gravity than the waste water, at the time of carrying out biological treatment of the waste water.
CONSTITUTION: Waste water is sent by the pump 1 from the bottom of treating vessel equipped with the waste water jetting tube 2 at the central part and the flowing direction shifting mechanism of jetting waste water 3 and the waste water is jetted from the tip end of the tube 2. The waste water is turned around by the flowing direction switching mechanism 3 and is flowed downward and then, is entered the treating zone 4. Here, the waste water is contacted with floating suspended particle group of many molten alumina hollow globe etc. having lower specific gravity than the waster water, carrying microorganism on the surface and biological treatment is carried out. The waste water is entered the separation zone 6 and is discharged from the suction opening 7 by the purified water discharge opening 8. The microorganism block stuck on the surface of the solid particles, is scraped off by the rotation of the blades 9 and is precipitated and then, is discharged from the sludge discharge opening 10.
