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。
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 re-moval rates of TN and TP by using an ecological filter with single FM(bamboo silk)were 81.8%and 84.4%,respec-tively.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.
