摘要
溶解氧水平是影响人工湿地处理效果的主要因素之一,对有机物、N和P等污染物的去除起着重要的作用。为此,综述国内外学者对人工湿地植物氧传输的研究发现,它能够改善湿地系统内的氧环境,从而推动硝化反应的进行,但是同种植物的氧传输量差异较大以及其变化趋势尚没有明确的结论。湿地植物氧传输受多种因素共同制约,其中温度、基质和光照等是主要因素。
The level of resolve oxygen is one of factors to treatment wastewater in constructed wetland.It is important to removal the organics,N and P.After literature review,release oxygen by plant can improve the oxygen environment in constructed wetland and beneficial to nitration reaction.But the quantity is different in the same kind of plant and the trend is not clearly.There are many factors which control the oxygen transport including temperature,substrate and illumination.
