虽然氧化塘工艺处理废水已被广泛研究和商业应用已经认识到，植物绿系统的集成还有待研究。本工作的重点是研究集成植物绿系统对传统氧化塘工艺处理废水的改进。在传统的处理系统中，植绿一体化氧化塘工艺似乎是一个有效的系统，影响重金属的生物去除。研究了包括两种不同水生植物（香蒲和黄水鳖）的综合植物绿系统对湿地生态系统的影响。在常规氧化池工艺中，研究了13天的保留时间。结果表明，当两种植物组合在一起时，在13 d的停留时间内，系统对铜、镁、镉、铬、镍、铁、铅和锌的去除率分别达到最大值79.07%、68%、61.07%、69.17%、74.87%、81.17%、62.07%和63%。研究了停留时间与重金属去除率之间的正相关关系，并通过相应重金属与停留时间的负相关和显著相关系数证实了这一点。结果表明，由两种不同的水生植物组成的复合植物绿系统（T。arzgustifolia sp.和黄泽苣苔（Limnocharis flava sp.）在传统的氧化池工艺中，是一种可靠的和生态上有吸引力的选择。最后，植物绿的整合，以减少废水中的重金属污染。(C)2015爱思唯尔有限公司版权所有。
Although the oxidation pond process for the treatment of wastewater has been widely studied and commercial application has already been recognized, the integration of the phytogreen system has yet to be studied. This work was focused on investigating the improvement in the conventional oxidation pond process produced by the integrated phytogreen system for the treatment of wastewater. Among the conventional treatment systems, the phytogreen integrated oxidation pond process appears to be an efficient system, affecting the bio-removal of heavy metals. The influence of the integrated phytogreen system, including two different aquatic plants (Typha angustifolia sp. and Limnocharis flava sp.) in the conventional oxidation pond process, was investigated for a retention time of 13 days. The results revealed that the integrated phytogreen system realized the maximum removal of copper to 79.07%, magnesium to 68%, cadmium to 61.07%, chromium to 69.17%, nickel to 74.87%, iron to 81.17%, lead to 62.07% and zinc to 63% at a retention time of 13 days when the two plant species were combined together. A positive relation between retention time and heavy metal removal was studied, and it was confirmed by the negative and significant correlation coefficients of the corresponding heavy metals with retention period. The results revealed that the integrated phytogreen system consisting of two different aquatic plants (T. arzgustifolia sp. and Limnocharis flava sp.) in the conventional oxidation pond process is a reliable and ecologically attractive option. Finally, integration of phytogreen is proposed to minimize heavy metal contamination in wastewater. (C) 2015 Elsevier Ltd. All rights reserved.
