摘　　要：为研究香蒲在夏季环境下对不同负荷污水净化的作用,本文采用无土培养挺水植物香蒲,进行不同浓度梯度处理下净化水体的静态试验。试验结果表明:试验水体的浓度与叶绿素a、蓝绿藻数的最大值呈正相关,香蒲对低浓度水体的氨氮、TP、TN净化效果影响最好,去除率分别为98.01%,92.35%,96.64%。In order to research the purification effect on different nutrient sewage in summer environment, the paper used emergent aquatic plant Typha orientalis to purify the different concentration sewage water in outdoor. The static experiment result shows that concentration of test water is a positive correlativity with chlorophyll a and blue - green algae numbers. Meanwhile, removal efficiency of low concentration is the best, and the influent removal rates in ammonia nitrogen, TP and TN are 98.01% , 92.35% and 96.64% respectively.
