Title:
【発明の名称】コロイド状ラッカ汚泥液の処理方法
Document Type and Number:
Japanese Patent JPH03502070
Kind Code:
A
Abstract:
A waste product of the treatment of scrap metal and similar and steelmaking consists of a metal dust containing oxides of various metals, in particular iron, aluminium and zinc, in differing proportions by weight depending on the type, which must be disposed of. Until now, this type of metal oxide dust, which is produced for example in foundries, has been discharged onto refuse dumps. This practice is obviously environmentally unsafe as well as uneconomical. The solution proposed by the invention is to use the metal oxide dust to coagulate and strip colloidal solutions of lacquer sludge or lacquer overspray produced during lacquering of motor vehicles.
