Title: | Efficiency of biological treatment affected by high strength of ammonium-nitrogen in leachate and chemical precipitation of ammonium-nitrogen as pretreatment | Authors: | Li, XZ Zhao, QL |
Issue Date: | Jul-2001 | Source: | Chemosphere, July 2001, v. 44, no. 1, p. 37-43 | Abstract: | Leachate samples with a high strength of ammonium-nitrogen (NH??-N) were collected from a local landfill site in Hong Kong. Two experiments were carried out to study (1) the inhibition of microbial activity of activated sludge by NH??-N and (2) the chemical precipitation of NH??-N from leachate as a preliminary treatment prior to the activated sludge process. The experimental results demonstrated that the efficiency of COD removal decreased from 97. | Keywords: | Ammonium-nitrogen Landfill leachate Chemical precipitation Magnesium ammonium phosphate |
