WATER TREATMENT DEVICE

摘要

A water treatment device (1) is provided with: a biological treatment tank (2) for storing a stored liquid (5); a pump (7) for generating a circulating liquid flow formed of the stored liquid (5); a gas-liquid two-phase flow generation device (8) for using the circulating liquid flow to suction a gas containing oxygen, whereby a gas-liquid two-phase flow in which the gas is dispersed in the circulating liquid flow is generated; and a nozzle (12) for injecting the gas-liquid two-phase flow into the biological treatment tank (2). Such a water treatment device (1) is capable of adequately circulating the stored liquid (5) in the biological treatment tank (2), adequately aerating the stored liquid (5), and adequately treating the stored liquid (5).

主权项

1. A water treatment device, comprising:
a biological treatment tank configured to store a stored liquid containing organisms that decompose contaminants; a pump configured to generate a circulating liquid flow formed of a circulating liquid extracted from the stored liquid; a gas-liquid two-phase flow generation device configured to use the circulating liquid flow to suction a gas containing oxygen and thus generate a gas-liquid two-phase flow of the circulating liquid having the gas dispersed therein; and a nozzle for injecting the gas-liquid two-phase flow into a region that stores the stored liquid.
