改性粉煤灰处理校园生活污水试验研究

摘要

In this study, fly ash from thermal power plant was used as adsorbent to study the adsorption of campus domestic sewage.Through various types of modification of fly ash, the influence of modified fly ash on the adsorption performance of sewage was analyzed.The results show that the modified fly ash has obvious adsorption and removal effect on the total nitrogen, total phosphorus and COD of domestic sewage, which provides apreliminary theoretical basis for the utilization of fly ash in domestic sewage treatment.%本研究以火电厂粉煤灰为吸附剂对校园生活污水进行吸附试验研究.通过对粉煤灰进行各种类型的改性, 分析改性后粉煤灰对污水吸附性能的影响.结果表明经改性后的粉煤灰对生活污水的总氮、总磷和COD等指标都有明显的吸附去除效果, 为探讨粉煤灰资源化利用于生活污水处理提供初步理论依据.
