Abstract
A first treatment tank () to a fourth treatment tank are installed prior to ultrapure water production apparatus (), dilute wastewater recovering apparatus (), general service water recovering apparatus and wastewater treatment apparatus. The treatment tanks (, . . . ) each have a micro-nano bubble generation tank (, . . . ) and an anaerobic measuring tank (, . . . ). Accordingly, microbes within the respective anaerobic measuring tanks (, . . . ) are activated by micro-nano bubbles generated in each micro-nano bubble generation tank (, . . . ) to thereby enhance the treatment efficiency of low-concentration organic matter. Further, when the value measured by dissolved oxygen meter (, . . . ) or oxidation-reduction potentiometer (, . . . ) of each anaerobic measuring tank (, . . . ) exceeds an individually determined given range, the rotational speed of a circulating pump (, . . . ) is controlled to thereby decrease the generation of micro-nano bubbles. Thus, the micro-nano bubble content in water undergoing treatment is held appropriate.
