REMOVING METHOD OF GLYCOL POLYMER

摘要

PURPOSE: To efficiently remove a glycol polymer from a water soluble waste liquid containing this polymer to enable to discharge the treated waste liquid as it is. CONSTITUTION: This removing method is composed of a 1st process for executing wet oxidation reaction by allowing the glycol polymer containing liquid to be treated to contact with an oxidizing agent and heating the material to be treated at 50-370 deg.C while keeping liquid state and a 2nd process for activated sludge treating the material to be treated, which is oxidation treated in the 1st process. By the method, the waste liquid of a water soluble oil is easily treated.
