| Abstract: |
| The semi-industrial experiment for acid waste water treatment in nonferrous smelter was conducted via High Density Slurry (HDS)-ferrous salt process. The results indicate that, both Pb and Zn could meet the requirement of the national emission standards through the HDS-ferrous salt process at pH10 as concentration in HDS system effluent could be controlled to less than 10 mg/L. The solid content in HDS sludge is up to 27%, which significantly is higher than that in LDS sludge(<2%). |
