Study on Leachate Adsorption by Activated Carbon Made from Sewage Sludge and Straw

You Lan Chen, Shan Wu

Abstract

Activated carbon of activated sludge and straw with pyrolysis was used as adsorbent, and its adsorption of organic matter in the leachate and influence facts were studied. The results showed that the economic and reasonable addition of straw in the raw of activated sludge was 45% and the optimum adsorption conditions were 40 min, duration of pH 4.0 and resin dosage 2%,the removal rate of COD reach 69.63%. Langmuir isotherm equation could better describe the adsorption behavior of COD on the activated carbon and it was a monolayer adsorption reaction.
