摘要
凹凸棒土经预处理后在不同温度下进行煅烧改性,研究其对自制含磷废水中磷去除率的影响。结果发现,凹凸棒土对含磷废水的脱除以吸附为主,与其比表面积存在相关性,随比表面积增大其对磷的去除率增强。
Modified Attapulgite was obtained by calcining at different temperatures.The removal rate of phosphorus in wastewater was investigated.The result showed that the removal rate of phosphorus was determined by adsorbability of the modified attapulgite.And attapulgite with larger specific surface area has a stronger adsorbability to phosphorus in wastewater.
