摘要:

对比研究了2个平行的不同滤料生态滤池净化校园生活污水的效果、特性。结果表明:当HRT=8 h时,竹丝+凹土陶粒混合滤料生态滤池对TN、TP的平均去除率分别达到90.5%、93.7%;竹丝滤料生态滤池对TN、TP的平均去除率分别为81.8%和84.4%。对2个生态滤池氮素去除率进行回归分析,建立了相对稳定的NH4+-N、TN去除率回归方程。

Abstract:

This study compared the characteristics and mechanisms of two parallel ecological filters with different filter materials(FMs) for schoolyard domestic sewage purification. The experimental results showed that when HRT equals to 8 h, the TN and TP were effectively removed by using an ecological filter with hybrid FMs(bamboo silk+ attapulgite ceramsite), and the mean removal rates of TN, TP were 90.5%, 93.7%, respectively. While the mean removal rates of TN and TP by using an ecological filter with single FM(bamboo silk) were 81.8% and 84.4%, respectively. The regression analysis by using SPSS was conducted according to the N removal rate of two ecological filters, and the stable regression equations of NH4+-N and TN removal rate was obtained.

Key words: water bioremediation, ecological filter, filter materials(FMs)
