| 摘 要： | 利用改性凹土与聚氨酯原料混合发泡,制备复合载体,对微污染河水的NH4＋-N和TOC的去除效果进行实验研究,结果表明对NH4＋-N、TOC的去除存在着明显的时段性,随着时间的延长,出水NH4＋-N、TOC的去除效率逐渐降低,最终趋于稳定。改性后凹土制备的复合载体对NH4＋-N、TOC处理能力得到提高,NH4＋-N去除率从37.50%提升到75.10%;TOC去除率从15.34%提高到36.15%。

| Abstract: | A series of composite carriers were synthesized by adding modified attapulgite to polyurethane. This paper studied on the removal efficiency of NH4＋-N and TOC in micro-polluted water. The result showed that with the extension of time,NH4＋-N,TOC removal efficiency decreased and stabilized eventually. NH4＋-N and TOC removal efficiency by modified attapulgite is much higher than that by unmodified attapulgite. The removal rate of NH4＋-N increased from 37. 5% to 75. 1%,while the removal rate of TOC advanced from 15. 34% to 36. 15%. |
