摘要
Abstract
An experiment was conducted to study optimization of operation conditions for membrane bioreactor at ambient temperatureto treat landfill leachate. The result showed that the membrane intercepted and enriched a lot of nitrobacteria with long generation time to make them as dominate bacteria in short time. So it was able to remove NH3-N from leachate with high rate. The process was operated with parameters as NH3-N load rate of 0. 082 ～ 0. 109 g/g MLSS · d; CODcr load rate of 0.136 ～ 0. 192 g/g MLSS · d and DO of 2.0 ～3.5mg/L The removal rates of NH3-N and CODCr were 95％ ～98％ and 60％ ～70％,respectively, being good effects of denitrification.关键词
