摘要
考察了基质类型及季节变化对人工湿地氮去除效果的影响,结果显示:基质类型对水平潜流人工湿地氮的去除效果有显著影响,煤渣基质比组合基质更利于提高人工湿地对氮的去除效果;季节不同,人工湿地氮的去除效果存在差异,平均去除率由高到低的顺序为:夏季〉秋季〉春季〉冬季。
Substrate types and season changes were employed to study the effects on nitrogen removal efficiency of the constructed wetlands. The following conclusions are concerned by the study. Nitrogen removal efficiency can be affected by substrate types, compared with the combined substrate, cinder substrate is more fit for the removal of nitrogen. Season changes has a significant impact to nitrogen removal efficiency, the sequence of average nitrogen removal efficiency is summer 〉 autumn〉 spring 〉 winter.
