【摘要】 通过对材料的选择及对湖水水质的分析,优化了材料的组合方法.研究表明,陶粒+pva无纺布+pp棉+活性炭+滤纸.通过湖水的测定出水的氨氮去除率为99. 9%,铵态氮的去除率为85%,COD的去除率为78%.开发便携式饮用水过滤器,通过多种滤料相互组合,经水质检测仪检测各项标准已经达到《生活饮用水卫生标准》(GB 5749-2006)的要求,具有很好的应用前景.更多还原

【Abstract】 The filtration research was to choose the best filter material using in lake for drinking. The results showed that the removal rate of ammonia nitrogen was 99. 9%,the removal rate of ammonium nitrogen was 85%,and the removal rate of COD was 78%,when chosen the composite filter material"ceramsite + pva non-woven cloth + pp cotton + activated carbon+ filter paper". The research could met the standard requirements of GB 5749-2006. At the same time,the appearance of the filter was reasonably designed. In the future,the portable water would have a good market application value.更多还原
