Abstract :
The paper studied the effect of different solid-liquid ratio, pH, temperature, stirring time and the size of light-burned magnesium on copper effluent concentration, when light-burned magnesium treats simulated copper wastewater 50mg/L combined with chitosan. The results show that: considering economic costs and the actual operability, when the experiment conditions with light burned magnesium-chitosan ratio 2:0.08, solid-liquid ratio 2g:250mL, reaction temperature, stirring time 30min, the effluent copper iron concentrations are less than 1mg/L, the range of PH is from 7 to 9.They meet the national secondary standard(1mg/L) (GB8978 1996).
