| 摘 要： | 设计并构建天然沸石与泥炭生物滤池装置,实验考察其在微污染水体中脱氮除磷的性能,研究其形成生物膜系统后对污染物去除的机理及其效果。实验结果表明:泥炭吸附水溶液中的磷酸根能力提高,但会释放氨氮,致使天然沸石吸附水溶液中的氨氮能力下降;形成生物膜系统的天然沸石与泥炭可同步去除微污染水体的污染物,装置运行稳定后的CODcr、NH4+-N和TP去除率分别可达80%、95%和41%;通过生物作用可使天然沸石与泥炭再生,实现材料持续使用。

| Abstract: | A biofilm system device with natural zeolite and peat was designed to observe the nitrogen and phosphorus removal efficiency in micro-polluted water.The mechanism and effect of pollutants removal were also investigated after the formation of biological membrane system.The results showed that the ability of phosphate removal in aqueous solution by peat was improved,but peat released ammonium nitrogen,the ability of ammonium nitrogen removal in aqueous solution by natural zeolite was decreased.Ammonium nitrog... |
