摘要: A water treating method is disclosed. Water stored in a container circulated through an external passageway and subjected to ultraviolet radiation biological oxidation treatment, whereupon the growth of undesired aquatic chlorophyceae microorganisms inhibited at same time, organic matter decomposed removed, thereby maintaining low COD level clarifying container. This particularly useful for keeping clean.
