为了研究人工湿地系统对含油废水的净化效果,组建了4组人工湿地系统在野外环境中进行含油废水的处理实验,4组系统均选用沸石、蛭石、生物陶粒、果壳作为填料,其中3组系统分别种植芦苇、香蒲和海寿花,1组为对照组(未种植植物).实验结果表明:人工湿地系统对含油废水具有较好的净化效果,对石油类污染物去除率(平均值)分别为菖蒲组(98.08％)＞芦苇组(97.29％)＞海寿花组(97.01％)＞对照组(96.16％),且菖蒲组中石油类污染物去除率与水温、pH(6.48～7.72)和DO(0.87～2.94 mg/L)均具有显著统计学意义(p＜0.01);菖蒲组对COD、TN和TP去除率(最高值)分别为80.49％、67.18％和47.81％.“,”Four constructed wetlands systems were built in order to figure out the purification effect on petroleum-containing wastewater in the field environment,the zeolite,vermiculite,biological ceramsite and nut shell were selected as fillers.The three systems planted acoruscalamus,phragmitesaustralis and pontederiacordata separately,one system as the control group without wetland plants.The result shows that the constructed wetland systems display a good effect on purifying petrochemical wastewater.The order of petroleum pollutant(PP) removal rate(average value) is as follows:Acorus calamus(98.08％)＞ Phragmites australis (97.29％)＞ Pontederia cordata(97.01％)＞ control group(96.16％),and PP removal rate by Acorus calamus group has a significant statistical significance with water temperature,pH (6.48 ～7.72) and DO (0.87～2.94 mg/L)(Pearson correlation coefficient,p＜0.01);the removal rate of COD,TN and TP (maximum value) are 80.49％,67.18％ and 47.81％ respectively.
