负荷及温度对人工湿地去除有机物的影响

利用海泡石这一江西特有的矿物质为基质,辅以香根草等适应环境能力强、去污效果好的植物,构成海泡石人工湿地系统。通过试验发现,湿地系统进水CODC r的变化范围为57.4~366.7 mg/L时,出水浓度基本维持在6.7~69.3 mg/L之间;试验阶段冬季平均温度达到5℃以上,湿地处理有机物能力随温度变化不大。该人工湿地具有很好的稳定性及抗冲击负荷能力,并且温度在湿地系统对有机污染物的去除中所起的作用不显著,两者并不存在明显的相关性。

Influence of Load and Temperature on Contamination Removal in Constructed Wetland

This paper studies the constructed wetlands that consist of the sepilite and the fragrant root grass.Sepilite,as a matrix,is an unique mineral substance from Jiangxi province.The fragrant root grass is a kinds of plants with strong ability to adapt the environment and high efficiency to remove the pollutants.The results show that the effluent concentrations of CODCr remain between 6.7 mg/L and 69.3 mg/L when influent concentrations ranged from 57.4 mg/L to 366.7 mg/L.In winter,the average temperature is abo...
