Abstract
PURPOSE: To facilitate the coagulating precipitation of waste liquid containing silicon compounds, fats, oils and sodium sulfate, by adding a compound, which can easily discharge alkaline earth metal ion, to the waste liquid at an ordinary temperature, and coagulating the waste liquid.
CONSTITUTION: A compound, which can easily discharge alkaline earth metal ion, is added to waste liquid containing silicon compounds, fats, oils and sodium sulfate at a rate of 100ppm or more as the alkaline earth metal ion at an ordinary temperature, to purify the waste liquid by coagulating precipitation. In this case, 0.5W1.0pt.wt. of a compound, e.g. aluminum chloride or aluminum sulfate, which can easily discharge aluminum ion, may be conjunctly added with 1pt.wt. of an alkaline earth metal compound. The alkaline earth metal compound may be an inorganic salt of calcium, magnesium, barium or strontium.
