摘要：

组建了两个平行的生态滤池用于净化校园生活污水，对比研究了滤料差异而产生的不同净化特性和机理。实验结果表明：竹丝/陶粒复合滤料生态滤池对氨氮、总氮、总磷的平均去除率分别达到了89.5%、90.5%、93.7%。相比于单一滤料生态滤池而言，复合滤料生态滤池内具有更复杂的生态系统、更丰富的根系和更多的生物种群量以及良好的耦合效应，导致复合滤料生态滤池具有比单一滤料滤池更好的除磷脱氮效果。

Abstract:

Two parallel eco-filters have been set up for the purification of domestic sewage in the campus. Different purification characteristics and mechanisms resulted from filter difference are contrasted and studied. The experimental results show that the average removing rates of NH₄⁺-N,TN and TP by the eco-filter consisting of bamboo filament/porcelain granule composite filter can reach 89.5%,90.5% and 93.7%,respectively. Compared with the ecofilter consisting of single filter,the eco-filter consisting of hybrid filters has more complex ecological system,richer roots,more biological population quantity,and good coupling effect. It leads to the result that the eco-filter consisting of hydrid filters has better dephosphorization and denitrification effects,than the eco-filter consisting of single filter.

Key words: eco-filter, dephosphorization &, denitrification, hybrid filters, domestic sewage
