Abstract

PURPOSE: To separate organics and phosphorus from water at a high efficiency, by charging an activated sludge to water containing organics and phosphours, and subjecting the water to an aerobic treatment followed by an anaerobic treatment to separate phosphorus as a culcium compound.
CONSTITUTION: Raw water 6 is introduced with a returned sludge 7 to an aeration vessel 1, and subhected there to an aeration treatment, by which organics are decomposed by bacteria and phosphorus is absorbed by the bacteria. The treated solution is separated to a solid part and a liquid part in a precipitation vessel 2. An extracted sludge 9 is carried to a phosphorus discharging vessel 3, where a solution is kept at pH about 6W9 and agitated slowly in an anaerobic atmosphere. The bacteria consume phosphorus contained therein and discharge phosphate ions. The phosphate ions are separated as precipitations by the addition of a calcium compound 11. The treated solution is separated to a solid part and a liquid part in a separation vessel 4. The sludge 7 is returned to the aeration vessel 1. The liquid part 13 is carried into a precipitation vessel 5 where the liquid part comes in to contact with crystal seeds containing calcium phosphate in the presence of calcium ions to separate the phosphate ions.
