摘要
生物处理方法是水处理中的重要部分。藻类由于其对氮、磷的高利用率以及较快的增殖速度使其在生物处理方面发挥了重要作用。本研究选用了自然界中4种常见的藻种小球衣藻、斜生栅藻和鱼腥藻、绿球藻,通过控制藻类物种数量的不同来探讨生物多样性对于污水中氮、磷元素去除的影响。结果表明,藻类生物多样性可以明显抑制藻类的生长,通过对氮、磷元素的分析显示,其可以明显促进水体中氮、磷元素的去除。
Biological treatment is an important part of wastewater treatment. Due to high availability of nitrogen and phosphorous and fast growth rate, microalgae plays a significant role in biological treatment. In this paper, Chlamydomonas microsphaera,Scenedesmus obliquus ,A nabaena sp. and Chroococcus sp. which distributed widely in natural environment were selected, the effects of biodiversity on removal of nitrogen and phosphorous in wastewater were studied by control the amount of different microalgae species. The results showed that microalgae biodiversity could restrain microalgae growth distinctly. The analysis on the content of nitrogen and phosphorous revealed that biodiversity could promote the removal of nutrients in wastewater.
