| 摘 要： | 本试验研究了3种浮萍(芜萍、少根紫萍、青萍)对3种不同稀释倍数的猪场厌氧废水中的N、P净化效果,结果显示:污水中TN、TP浓度随浮萍处理时间增加而持续降低;少根紫萍对N、P净化率都超过了75%,净化能力优于芜萍和青萍。综合考虑,少根紫萍可作为四川盆地内净化养殖废水中氮、磷的优化品种。

| Abstract: | In the experiment, we studied the three kinds of duckweed＇s purification effect on N, P which from different dilutions anaerobic wastewater. The results showed that the TN, TP concentration decreased continuously with the action time extending by duckweed. The purification rate of Spirodela oligorrhiza was more than 75%, its purification ability was better than that of Wolffia arrhiza and Lemna aequinoctialis. This results indicated that spirodela oligorrhiza was the optimized duckweed which could be used to purify P and N from the breeding wastewater in Sichuan basin. |
