FAMS对水体的净化率研究

Study on Water Purification by FAMS

对FAMS系统的不同种类组合进行试验,探求不同种类配置的FAMS净化率。结果表明,FAMS能提高水体对COD的净化率,COD去除率提高最大为28 4%,平均为11 9%。FAMS对总氮(TN)和总磷(TP)的去除效果更明显,TN的去除率提高最大为58 8%,平均为22 98%;TP的去除率提高最大为68 1%,平均为46 1%。试验结果还表明,具有两层次群落结构的FAMS系统能改善植物在污水中对环境的适应,使原来无法存活的一些敏感种类能在污水中存活,且发挥FAMS的正常净化功能。

Different combination of FAMS(Floating Aquatic Macrophyte-based Treatment System)types are embraced to pursue higher water purification rate.As a result,FAMS is able to improve the purification rate of water on COD with 284% as the maximum removal rate,119% as average,58.8% as the maximum removal rate on TN,22.98% as average,68.1% as the maximum removal rate on TP and 46.1% as average.Also shown by the experiment is the fact that the two layer structured FAMS system is able to improve the environmental adaptability of plants in the sewage water and some sensitive species that once could not survive can make a living and play a normal role FAMS purification.
