【Abstract】 Polyaluminium ferric chloride(PAFC), a newtype of inorganic flocculant, was prepared by utilizing dust collected from exhaust fume with electrostatic precipitator. PAFC structure was analyzed with infrared spectrophotometer and Xray diffractometer. PAFC flocculation property in treatment of leather tanning wastewater has been investigated. The total Cr and COD can be removed by over 99% and 78%, respectively. The results are better than those of AlCl 3.更多还原
