<p>PURPOSE:To smoothly perform microbiological treatment, by introducing a part of waste water to be treated into a preliminary acclimation device (hereinafter referred to as P.A.D.) system of a bacteria preparation before introducing the same into a waste water treatment apparatus utilizing bacteria. CONSTITUTION:Waste water satisfying conditions of water temp., pH, NH3, PO4 or dissolved oxygen is introduced into P.A.D. system from a conditioning tank and an activating agent such as whey or dog food is charched in the basket provided to the upper part of the P.A.D. system. After bacteria are aged in the P.A.D. system, waste water is sent to a microbiological treatment apparatus from the P.A.D. system while the quantity thereof is adjusted and treated. By this method, microbiological treatment is smoothly performed.</p> |
