Abstract

PURPOSE: To even the deposition distrubition of microbes by arranging in parallel plural rotary bodies of increasing specific area in the direction from the waste water inflow side to the outflow side.
CONSTITUTION: Rotary discs 4 fixed coaxially and in parallel with each other on a horizontal rotary shaft 3, to form disc groups a-d. The gap between the discs 4 in the disc groups a-d is reduced in the direction from the waste water inflow portion to the outflow portion. Baffle plates 2 are not necessarily required, according to the inflow speed, outflow speed, and amount of the waste water. This constitution evens the distribution of microbes deposited on the discs 4, stabilizes the treatment performance, and provides treat water of high reliability.
