Abstract
According to this wastewater treatment apparatus, wastewater can be treated by novel action by a foaming tank in comparison with a treatment method solely using a biological treatment tank constituting an aeration tank. That is, wastewater can be treated by action achieved by combining (1) action solely of a biological treatment tank and (2) action of a foaming tank . Specific action in this foaming tank includes supply of dissolved oxygen to wastewater and oxidation by bubbled air (micro air) under a favorable condition with a shallow water depth. According to this wastewater treatment apparatus, energy to be consumed can be saved and toxic chemical substances such as dimethylformamide as a toxic chemical substance can be completely decomposed by unlimited microorganisms.
