摘要： A process for purifying water that contains organic matter which comprises mixing a coagulant consisting of either a ferric salt alone or a ferrous salt and an oxidant into sewage that contains organic matter in a high concentration, causing the coagulantcontaining sewage to flow into a flocculating region, agitating the sewage for floc formation and growth, separating the floc in a sedimentation region into effluent and sludge, thus obtaining as the supernatant a sewage that contains organic matter in a low concentration, introducing said sewage into an aeration tank in which iron floc is formed, allowing microorganisms to be adsorbed on the iron floc while the sewage is being aerated in said tank, thereby to obtain highly pure treated water.
