Abstract :
Aiming at handling oily waste water of steel-making enterprise, advective seperation of oil-coagulation-floatation-slag filtration technology routing was designed. Via static test, polyaluminium chloride etc. three kinds of coagulant were primarily selected. Coagulant for treating effect and rational operating conditions were determined. Optimized operating condition was: polyaluminium chloride dropping quantity was 50~70 mg/L, air solubility was about 45 mg/L, gas-oil ratio was 0.53 mL/mg or so, appropriate size floatation tank, slag filter column. Under the medicine dropping quantity and air solubility, wastewater oil removal rate reached more than 90%.
