jaue20130018: Concentrate Recharge Removal of NH3-N and Heavy Metal Ions

Abstract

This paper studied by experiments landfill leachate and concentrate recharge NH3-N and heavy metals removal efficiency. The experimental results show that under the experimental conditions, the leachate recirculation and concentrate recharge NH3-N removal rate of about 60% to 70%, there is a certain removal. Concentrate recharge to the aerobic landfill body NH3-N removal rate is high, up to about 96%. Concentrate recharge before the pH adjusted to 11, the stable effluent NH3-N removal rate can be as high as 90% to 95%.
