摘要： A clarificant of wastewater comprises an aqueous solution of a polynuclear complex salt comprising sulfates of a plurality of the metals K, Fe, Ca, Na, Mg and Al, e.g. containing per 1000 ml of water 0.78-5.63 g K ions, 6.00-72.60 g Fe , 0.12-1.20 g Ca , 0.10-1.00 g Na , 6.56-19-70 g Mg , 6.21-35.00 g Al and 106.08-463.77 g SO4 ions. It is prepared by heating, e.g. at 100 DEG - 190 DEG C and a pressure of 1 to 10.0 kgf/cm , isochorically an aqueous solution containing the said mixture of sulfates, e.g. containing 0.02-0.08 M K , 0.11-1.31 M Fe , 0.003-0.30 M Ca , 0.004-0.40 M Na , 0.27-0.81 M Mg and 0.370-1.300 Al . The solution is added to and rapidly stirred with wastewater to adjust its pH to 4-5 and an alkali, e.g. Ca(OH)2, is added until the pH is 6-8.5, so as to flocculate nearly all the suspended contaminants and the floc is removed. The wastewater treated can be industrial or domestic effluent water or natural water, and there is thus obtained a reduction in biological and chemical oxygen demands and in suspended solids.

摘要： A clarificant of wastewater comprises an aqueous solution of a polynuclear complex salt comprising sulfates of a plurality of the metals K, Fe, Ca, Na, Mg and Al, e.g. containing per 1000 ml of water 0.78-5.63 g K⁺ ions, 6.00-72.60 g Fe⁺⁺, 0.12-1.20 g Ca⁺⁺, 0.10-1.00 g Na⁺, 6.56-19-70 g Mg⁺⁺, 6.21-35.00 g Al⁺⁺⁺ and 106.08-463.77 g SO₄⁻⁻ ions.
It is prepared by heating, e.g. at 100° - 190°C and a pressure of 1 to 10.0 kgf/cm², isochorically an aqueous solution containing the said mixture of sulfates, e.g. containing 0.02-0.08 M K⁺, 0.11-1.31 M Fe⁺⁺, 0.003-0.30 M Ca⁺⁺, 0.004-0.40 M Na⁺, 0.27-0.81 M Mg⁺⁺ and 0.370-1.300 Al⁺⁺⁺.
The solution is added to and rapidly stirred with wastewater to adjust its pH to 4-5 and an alkali, e.g. Ca(OH)₂, is added until the pH is 6-8.5, so as to flocculate nearly all the suspended contaminants and the floc is removed.
The wastewater treated can be industrial or domestic effluent water or natural water, and there is thus obtained a reduction in biological and chemical oxygen demands and in suspended solids.
