Abstract

PURPOSE:To treat the waste water of washing efficiently with a simple device by separating oil contents and solids from the concd. liquid obtd. by distillating and concentrating the waste liquid of washing at pretreatment stages. CONSTITUTION:In the pretreatment stages of transfering worked articles to a finishing stage by subjecting the same to the respective stages of defatting, the 1st washing, the 2nd washing, chemical conversion, the 3rd washing, the 4th washing and the 5th washing, fresh washing water is supplied to the 5th washing stage and is used in washing said articles thereo, after which it is used successively in the 4th, the 3rd, the 2nd, the 1st stage, and from the 1st washing stage, it is discharged as waste water of washing to a distilling and concentrating device. The distilled water obtd. in the distilling and concentrating device is cyclically used as washing water in the 5th washing state, and the concd. liquid obtd. by the distillation and concn. is recovered of useful oil contents in an oil separator. The residues recovered from the remaining liquid are dehydrated. dried and solidified in a drying and solidifying device such as filter press, after which they are discarded.
