摘要
以西安市兴庆湖为研究对象,研究了季节变化对人工湿地净化城市湖泊水体效果的影响。结果表明:人工湿地对污染物的去除效果受季节变化的影响较大,秋季湿地对CODCr的去除率比冬季高19.58%,对TN的去除率比冬季高33.79%,而对TP去除率的影响不明显,对NH3-N的去除率比冬季低20.03%。
The paper studies the seasonal variation effect of constructed wetland for urban lake water purification by taking the Xing-qing Lake in Xi＇an as the research object.The experimental results show that： constructed wetlands for removal efficiencies of pollutants greatly influenced by seasonal variation.For example,the removal rate of CODCr is 19.58% higher in autumn than that of in winter,the removal rate of TN is 33.79% higher in autumn than in winter.However,the seasonal changes had no obvious effect on the removal rate of TP.
