【摘要】 通过实验研究芦苇湿地对垃圾渗滤液中含氮污染物的去除,并探讨芦苇湿地各部分氮含量分布及变化规律.实验结果表明:垃圾渗滤液处理过的芦苇湿地土壤及芦苇根茎含氮量增加;茎叶含氮量明显高于芦苇根及土壤;芦苇生长过程能够固定环境土壤中的氮,芦苇能去除垃圾渗滤液中的部分含氮污染物.芦苇土壤含氮量未超出芦苇忍耐限度(177.67×103~255.67×103mg/kg),还可以进一步增加垃圾渗滤液的处理量.芦苇湿地可能是处理垃圾渗滤液的一条有效途径.更多还原

【Abstract】 The removal of nitrogen pollutants in landfill leachate was estimated,and the reed nitrogen distribution and variation were explored. The results show that the nitrogen concentration was decreased in the soil and rhizome,the nitrogen concentration in stem and leaf was higher than it in the root and soil,and the reed can fix nitrogen in the soil and wipe of some nitrogen pollutants in landfill leachate. The nitrogen concentration in the soil does not reach the limit(177. 67 × 103- 255. 67 × 103 mg /kg),and the capacity can be further increasing. The reed wetland may be an effective way to treatment of landfill leachate.更多还原
