芦苇与香蒲对富营养化水体中 氮磷去除效果的比较

对总氮和总磷分别超过30 mg/L 和8 mg/L 的富营养化水体，用芦苇和香蒲进行了3 个月的试验净化。 结果表明，两种植物对氮和磷具有很好的去除作用，芦苇的去除率均高于香蒲。通过控制水生植物的水体覆盖率和 定期收割植株的方式能有效降低水体中氮磷含量。

Removal effect comparison of reed and cattail on nitrogen and phosphorus in eutrophic water

In the eutrophic water, three month trial purification was conducted by reeds and cattails to remove the total nitrogen and total phosphorus exceeded 30 mg/L and 8 mg/L respectively. The results showed that the two plants had high removal effect on nitrogen and phosphorus, while the removal rate of reed was higher than that of cattail. Through controlling water coverage of aquatic plants and harvesting plants, we can effectively reduce nitrogen and phosphorus content in water.
