不同配置人工湿地处理生活污水的比较

Different Configurations Constructed Wetland Sewage Treatment Comparison

在相同的条件下,开展了对3种不同类型的人工湿地处理生活污水效果的动态比较研究,并对其净化污水的结果进行比较分析。结果表明,人工湿地运行7 d时,优化组、对照组、传统组3种人工湿地对TN的平均去除率分别为68.79%,13.06%,46.82%;对TP的平均去除率分别为88.99%,74.98%,28.68%;对COD的平均去除率分别为76.03%,33.34%,38.22%。可知优化组对污水中TN,TP,COD的去除效果最好。通过分析证明了在不发生拮抗作用的前提下,优化配置后的人工湿地系统优于传统类型,由于在优化系统中各湿地组成单元之间的协同作用强弱关系,因此能够进一步的提升处理污水能力,这也揭示了人工湿地系统新的研究方向和广阔的应用前景。

Under the same conditions, a comparative research of the dynamics of three different artificial wetland sewage treatment effects was carried out, and comparative analysis of the results of its sewage purification. The results showed that when the artificial wetland ran 7 d, the optimization group, the control group and the traditional group of three artificial wetlands on average removal rates of total nitrogen were 68.79%, 13.06%, 46.82%, respectively;the average removal rates of total phosphorus were 88.99%,74.98%,28.68%, respectively; the average removal rates of COD were 76.03%, 33.34%, 38.22%, respectively. It was indicated that the optimal group was most effective on the removal of TN,TP and COD. It was proved that without antagonism,the optimized configuration the wetland system was superior to the traditional type. By optimizing the system each wetland unit consisting of synergies strength,it could further enhance the treatment capacity, which also revealed new research directions and broad application prospects of artificial wetland system.
