水库水源水生物陶粒滤池预处理中试研究

Pilot-Scale Bio-ceramic Filter for Reservoir Source Water Pretreatment in Southern China

    摘要
  • 摘要: 针对受污染的某水库水源水进行中试规模的生物陶粒滤池试验研究。试验结果表明，生物陶粒滤池预处理能全面净化水源水的水质。在气水比为0.75～1∶1，水力负荷为4～6 m3／(m2·h)条件下，对NH+4－N，NO-2－N和CODMn的去除率分别为89%～97.5%，97.5%～99％,20%～35%；对藻类的去除率为60.1%～84.3%。

     

    Abstract: A pilot－scale bio－ceramic filter (BF) for polluted source water from a reservoir in southern China is conducted. It is shown that the source water quality can be greatly improved by BF pretreatment. The removal rate of NH+4－N,NO-2－N and CODMn is 89%～97.5%,97.5%～99%,20% ～ 35% respectively. Moreover, the removal rate of algae is from 60.1% to 84.3% when the range of gas/water ratio is 0.75～1 to 1 and the hydraulic loading is 4～6 m3／(m2·h).
