| 摘 要： | 针对人工湿地中溶解氧浓度不足的问题,采用自动增氧型垂直流人工湿地处理系统进行了农村生活污水脱氮除磷对比试验研究。结果表明,自动增氧型湿地内的DO浓度比非增氧型人工湿地高0.3 mg.L-1左右,TN、NH4＋-N去除率分别达到了67.41%、69.04%,比非增氧型湿地高14.57%、19.79%,但TP去除率与非增氧型湿地差异不显著。说明自动增氧措施对于增加人工湿地中的DO浓度,提高脱氮效率是有效的,但对于除磷效率无显著影响。

| Abstract: | According to the problem of low dissolved oxygen（DO）content and nitrogen removal rate in the constructed wetland system,a self-aeration vertical flow constructed wetland was designed to treat the rural domestic wastewater by comparing with the non-aeration vertical flow constructed wetland.The results showed DO content of the self-aeration vertical flow constructed wetland was about 0.3 mg.L-1 higher than that of the non-aeration constructed wetland.Its removal rates of TN and NH 4＋-N were 67.41%,69.04%,respectively,and 14.57%,19.79% higher than those of the non-aeration constructed wetland,respectively,suggesting that it was a effective method to improve the nitro-gen-removal rate of the constructed wetland by the self-aeration measures.No difference was found for the phosphorus-removal rate between the two vertical flow constructed wetlands,which suggested that the self-aeration showed no significant influence on phosphorus-removal rate. |
