Abstract

PURPOSE:To aerate the liquid deeply with the compressed air from an ejector and improve air dissolution efficiency by supplying the raw water of the specified pressure to the liquid surface through the ejector on the raw water influent port inner side in the upper part of a hermetically closed tank used for the concentration of the activated sludge, etc. CONSTITUTION:Raw water is supplied under the specified pressure through the upper influent port 2 of a hermetically closed tank 1. Then, the air bubbles sucked through the suction and discharging of the compressed air supplied through an air feed port 5 in the ejector part at the time when the raw water passes the ejector 4 are finely broken and atomized and are evenly mixed in the raw water. This mixed matter penetrates down to near the tank bottom and the fine air bubbles diffuse in the entire part of the tank inside. At this time, a baffle plate 6 prevents the penetrating discharge flow of the ejector from going toward the effluent port 3.
