Abstract
PURPOSE: To heighten the speed of coagulation and precipitation, improve the nature of the treated water and decrease the amount of produced sludge, by adding polyvalent metal salt such as FeCl3, a cationic and an anionic organic high-molecular coagulants to the organic waste water and stirring the mixture.
CONSTITUTION: 100 to 500 mg/l of the polyvalent metal salt such as FeCl3, Al2(SO4)3, etc., 10 to 500 mg/l of the cationic organic high-molecular coagulant such as water-soluble aniline resinate and 0.5 to 10 mg/l of the anionic organic high-molecular coagulant such as polyacrylamide's partially hydrolyzed substance of about ten million in molecular weight are added to the orgnic waste water discharged from a pulp making process etc. The mixture is stirred to cause coagulation and precipitation.
