WIPO Patent Application WO/2011/024905

Kind Code:

A1

Abstract:

Provided is a biotreatment method for biotreatment of water that contains phenol, thiocyanogen, or the like. The provided method improves the quality of treated water while minimizing losses in treatment efficiency. The provided method, which treats water containing COD components including phenol and/or thiocyanogen, introduces said water into a biotreatment tank containing a sludge that contains bacteria capable of breaking down the aforementioned COD components, thus biologically treating said COD components by means of said bacteria. The provided method is characterized by a step that measures the total number of bacteria in the aforementioned sludge before the water to be treated is introduced into the biotreatment tank, thereby making it possible to keep the COD component load on each bacterium per unit time within a prescribed range.
