Document Type and Number:

WIPO Patent Application WO/2011/010587

Kind Code:

A1

Abstract:

Disclosed is a novel method for treating a liquid waste of a coating agent, which is simple in constitution, is easy to handle, can operate easily, and is highly efficient. Specifically disclosed is a method for treating a liquid waste containing a coating agent, which is characterized in that the liquid waste containing the coating solution is treated by supplying at least one of a treatment solution and the liquid waste into a treatment vessel in the form of finely divided liquid droplets and mixing the treatment solution phase with the liquid waste phase to form a flow of the mixture in an emulsified form (i.e., an emulsion flow). The method enables the treatment of a liquid waste of a coating agent in a simpler and easier manner compared to biological liquid waste treatment methods, and also enables the treatment of the liquid waste in a place where the liquid waste is produced.
