DEVICE FOR CIRCULATED WATER'S PUMPING AND AERATION

摘要

The device is suitable for the efficient airing of sewage water and even distribution of activated bilge in the required circulation of water in the circulating activated sludge tanks. It consists of a sucking chamber (3) with sucking holes. The chamber is placed in the circulating activated sludge tank (1). In the sucking chamber (3) above the bottom of the tank (1) body there is a circulation pump (5) with an air inlet and with a lifting piping (7). The lifting piping (7) opens into a de-aeration tank (8). The de-aeration tank (8) is equipped with a discharge tubing (9) linked to a separator (10) and then to outlet nozzles (11) of the aired water. The device ensures the efficient transfer of oxygen into the water. The content of the circulating activated sludge tank is evenly aired and its operation is cost-effective and reliable.
