| 摘 要： | 采取室内填料柱级配淋洗试验的方法,选取粉煤灰、煤渣、空心砖填料组合作为人工湿地填料,进行不同填料级配污水净化效果研究。结果表明:在相同进水水质和水力负荷运行条件下,粉煤灰、煤渣、空心砖以体积比3:1:1混合时,COD、TN、NH4+-N去除效果最好,去除率最高分别达到47.83%、81.93%、93.53%;粉煤灰、煤渣、空心砖以体积比1:1:3混合时,TP去除率较高,可达到85.97%。试验所选填料及级配对NO3--N无较好的去除效果。考虑到填料物理特性及长期稳定运行的需要,选择粉煤灰、煤渣、空心砖以体积比3:1:1混合填料作为人工湿地去污填料最为适宜。

| Abstract: | Indoor leaching column experiments were done to investigate the effect of gradation of substrate for constructed wetland used to treat sewage. Brown soil,fly ash,cinder and hollow bricks were used as filtering media with different proportions which resulted in optimized pollutants removal of COD,TN,NH4+-N as well as TP. It was concluded that a volume ratio of 3: 1: 1 of fly ash,cinder,and hollow bricks respectively mixed was suitable for constructed wetland treating domestic wastewater according to the expe... |
