METHOD FOR TREATMENT OF WASTE WATER

摘要

METHOD FOR TREATMENT OF WASTE WATER In removing color components and COD components from waste water, the waste water is treated with an inorganic adsorbent, the mixture thus obtained is subjected to a sedimentation treatment to separate the adsorbent containing the color and COD components as a slurry layer, and a portion of the adsorbent slurry is returned to the adsorption step and the remainder thereof is subjected to a regenerating treatment to recycle as an adsorbent. Pollution-free water is effectively obtained by the above method.
