Preparation and Application of Slag Compound Flocculant

Abstract:

A new kind of composite flocculant, polyaluminum ferric chloride (PAFC), was prepared using blast furnace dust and scrap material of aluminum. Tests about its application on the treatment of brewing wastewater were carried out and the flocculation mechanism was discussed. Results showed that the best condition for foluccation was: doses of PAFC was 40 mg/L, pH of wastewater was about 7.0, sedimentation time was 30 min, removal rate of turbidity, CODcr, decolorization and ammonia were 96.8%、64.7%、87.5% and 41.0% respectively.
