Abstract

AMD pollution was considered as the world wide problem, Nowadays many technology (especially biotechnology) was researched to purified the waste water. However, the solid waste produced by the procedure was seldom payed attention to. In this research, 4 flocculants were applied to recycle the Cu in the form of CuS to selected the most suitable flocculent and characters for recycling. Besides, solid waste mixture produced by bio-treatment of real AMD was treated to test the performance of the flocculants. The results shows that NPAM takes on a most suitable performance for recycling CuS. The initial pH should be adjusted lower than 2.5, and dosage of NPAM (1% m/m) was 3mL per 500 mL mixture, which contains about 180 mg/L Cu. If the content of Cu was more or less than it in the untreated mixture, the dosage should be adjusted based on the ratio compare with the original Cu content (180 m/L). The recycle ratio of solid waste produced by bio-treatment of real AMD was 78.47%, but the content of CuS was more than 80%, which could be the raw material for smelting Cu. The results could supply a theoretic bases for recycling Cu in the form of CuS.
