| Abstract: | In this paper, the treatment of tannery sludge by sodium hypochlorite has been researched. The results showed that 100% of Cr （ Ⅲ ） in the tannery sludge was removed by treating with 6% concentration of sodium hypochlorite, the liquid-solid ratio 22 g/g soil, temperature 60 ℃, reaction time 80min. |
