Study on Adsorption of Cu~(2+)in WasteWater by Residual Sludge as Adsorbent

摘要

Utilizing residual sludge as adsorbent to treat Cu~(2+)in wastewater,The effects of pH,concentration,sludge dosage,temperature and adsorption time on Cu~(2+)adsorption were studied.The results was showed that removal rate of Cu~(2+)was better using residual sludge adsorbent to adsorb wastewater containing 20 mg/L Cu~(2+)when adsorption tune was 3h,pH was 6~7,temperature was 20 °C and sludge dosage was 2.0 g/L..
