Title
(EN) METHOD FOR TREATMENT OF LIQUID WASTE OF COATING AGENT

(JA) 塗料廃液処理方法
Abstract
(EN)
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.

La présente invention a pour objet un nouveau procédé de traitement de déchets liquides d'un agent de revêtement, qui est de constitution simple, qui est facile à mettre en œuvre, qui peut fonctionner facilement, et qui est hautement efficace. La présente invention concerne spécifiquement un procédé de traitement de déchets liquides contenant un agent de revêtement, qui est caractérisé en ce que les déchets liquides contenant la solution de revêtement sont traités par l'introduction d'au moins une solution de traitement et des déchets liquides dans un récipient de traitement sous la forme de gouttelettes liquides finement divisées et le mélange de la phase de solution de traitement avec la phase de déchets liquides pour former un écoulement du mélange sous une forme émulsifiée (c'est-à-dire un courant d'émulsion). Le procédé permet le traitement de déchets liquides d'un agent de revêtement d'une manière plus simple et plus facile par rapport aux procédés de traitement des déchets liquides biologiques, et permet aussi le traitement des déchets liquides dans un endroit où les déchets liquides sont produits.
