| 摘 要： | 研究利用砂土与粘土混合制成的生态减污袋对于模拟污水中氨氮及磷的去除效果。研究发现砂土与粘土比例为1∶1的减污袋对于高浓度模拟污水中氨氮和磷的去除率分别达到73%和63%;而砂土与粘土比例为10∶1的减污袋对于低浓度模拟污水中磷的去除率最高达到49%。对于高浓度污水,采用砂土与粘土比例为1∶1的生态减污袋能取得最好的除磷去氮效果;而对于低浓度污水,采用砂土与粘土比例为10∶1的生态减污袋除磷去氮效果较好并且成本相对较低。

| Abstract: | Bags that filled with sand and clay were immersed in the simulated sewage in order to investigate the effect of the bags to remove ammonia nitrogen and phosphorus from the sewage.Sand and clay in different proportions were tested,and given that sand/clay ratio was 1∶1,removals of ammonia nitrogen and phosphorus would be 73% and 63% respectively from high-strength sewage.On the other hand,when sand/clay ratio was 10:1 removal of phosphorus would be 49% from the low-strength sewage. |
