<p>PURPOSE:To effectively prevent a degradation in the efficiency of a waste water treatment by an activated sludge method by using a bulking inhibitor consisting of water soluble sorbate and water soluble alkali metal salt. CONSTITUTION:The bulking inhibitor consisting of the water soluble sorbate such as alkali metal salt, ammonium salt or amine salt of sorbic acid and the water soluble alkali metal salt such as NaCl or KCl is added to any of a control chamber, aeration chamber, settling chamber or the routes thereof to prevent the abnormal generation and propagation of filamentous bacteria and to prevent bulking. the degradation in the efficiency of the waste water treatment is thus prevented.</p> |
