Abstract
PURPOSE: To remove heavy metal and alkaline earth metal simultaneously without using chemicals inexpensively and efficiently by adding an exhaust liquid of a viscose rayon factory to the waste water containing the heavy metal and the alkaline earth metal.
CONSTITUTION: To the waste water containing the heavy metal and the alkaline earth metal such as the waste water of a garbage incinerator or a plating factory, an exhaust liquid of a viscose rayon factory to make the heavy metal and the alkaline earth metal insoluble. This insoluble heavy metal and alkaline earth metal are separated from the waste water by a precipitating, a floating or a filtering method. As described above, without using commercial chemicals, the waste water treatment is carried out inexpensively and efficiently by a side product.
