chinois. 通过建立模拟辽宁双台河口湿地的小试模型,并灌以造纸废水,分析模拟装置中水样、土样和植物样中氮的变化。结果表明:高浓度造纸废水的氮去除效果显著,且芦苇在不同生长期对同一浓度废水中N的去除效果为:拔节期抽穗期成熟期展叶期发芽期。NH4+-N主要分布于土壤表层,NO3--N有淋洗的作用,在土壤底层积累;TN随深度增加有所减少。芦苇不同器官的含氮量为:叶片茎秆根须根茎。

The experiment platform by establishing simulation merchant of estuary wetland double bench model,and imbedded in the papermaking wastewater,the changes of the nitrogen were tested in simulator of water soil and plant samples.The results showed that more effectiveness of N removal was in the high concentrations of papermaking wastewater treatment,and the removal efficiency was Jointing stagematurityheading stageexhibition leaf periodsprout period on the same concentration.NH4+-N mainly distributed in soil table.NO3――N had accumulation in depth;TN increased with depth reduced.nitrogen of reed in different organs is the stemleafrootsroot.
