Abstract

PURPOSE: To obtain high-quality drinking water with good taste and free from odors or the like by a method wherein BOD and the like in raw water are removed through a contact oxidation treatment by a biological slime formed on a packing material incorporated in a contact oxidation device, and then it is subjected to a slow filtration.
CONSTITUTION: Raw water is introduced into the first settling basin (a), where inorganic suspended solids (SS) and other coarse solids contained in the raw water are removed through natural sedimentation. The treated water discharged from the first settling basin (a) is transferred to the second step (2) comprised of the contact oxidation device (b) having the packing material incorporated in a water passage and the second settling basin (c), and the contaminants such as BOD, COD, SS, algae and the like contained in the treated water are removed through contact oxidation by the biological slime on the packing material. The water treated in the second process (2) is further treated by slow filtration in a slow filtration tank (d) to obtain good water quality with a turbidity of 2 or below and a potassium poermanganate consumption value of 10ppm or below, followed finally by sterilization (e) with chlorine to obtain high-quality drinking water (f).
