Disclosed is a method for processing waste water containing a silicon powder wherein waste water containing a silicon powder is made to contain an inorganic flocculating agent, which is composed of a silica sol-water soluble metal salt, so that the concentration of the inorganic flocculating agent is 15-300 (mg/L) in terms of the metal, and then an organic polymer flocculating agent is added thereto. In this connection, the silica sol-water soluble metal salt has a molar ratio of silicon to the meal of 0.05-3Ø With this method, waste water containing a fine silicon powder can be processed by flocculation.

La présente invention concerne un procédé de traitement des eaux résiduaires contenant une poudre de silicium, les eaux résiduaires contenant une poudre de silicium étant faites pour contenir un agent de floculation inorganique, lequel est composé d~un sel hydrosoluble de métal de sol siliceux, de sorte que la concentration en agent de floculation inorganique soit de 15 à 300 (mg/L) en ce qui concerne le métal, et ensuite un agent de floculation polymère organique y est ajouté. À ce sujet, le sel hydrosoluble de métal de sol siliceux a un rapport molaire du silicium par rapport au métal de 0,05 à 3,0. Avec ce procédé, des eaux résiduaires contenant une poudre fine de silicium peuvent être traitées par floculation.
