WASTE WATER TREATMENT APPARATUS BY AERATION AND OZONE

摘要

A wastewater necessary a high COD and BOD was treated by an oxidation feeding ozone gas in the wastewater. A heater(2) is installed at an inner bottom part of the body(9), a wastewater feeding inlet(3) and an air inlet(4) are formed. Ejectors (5),(7) having an air valve(V) are installed at an upper and bottom part of the body(9). An ozone generator is installed at outer part of the ejector(5). An air feeding part is linked to a inlet of sludge strainer(8), an outlet of the sludge strainer(8) is linked to a wastewater reservoir in the bottom of a drier(1).
