Abstract
The papermaking wastewater was treated with new inorganic polymeri c flocculant, polymeric aluminum magnesian silicate-sulfate developed by authors, and the factors concerned to influence the flocculent performance were discusse d, and the optimum technical conditions to treat wastewater were determined. Und er the optimum conditions, the removal of CODCr is more than 89%, which excels both polymeric aluminum silicate-sulfate(PASS),aluminum sulfate(AS) and polyac rylamide(PAM) in the flocculent performance.
