Abstract

This invention relates to a method of aggregation by adding inorganic aggregating agent after a biological treatment of organic efflux by aerobic process to remove soluble substances and suspension of biometabolites in biological treated water; wherein the amount of inorganic aggregating agent is decreased and an excellent treatment of aggregation water is obtained. The method for treating organic efflux comprises introducing the organic efflux into reaction tank (1) of biological treatment to carrier out aerobically biological treatment, and adding inorganic aggregating agent to the biologically treated water from the outlet of reaction tank (1) of biological treatment; wherein the pH value of biologically treated water at the outlet area in the reaction tank (1) of biological treatment is less than 7.3.
