摘    要:采用潜流人工湿地对给水厂原水进行预处理,以提高进水水质,减轻水厂常规处理工艺的负荷。以松花江水为研究对象,考察了人工湿地对原水中浊度、CODMn、UV254、TN和NH4^+-N的处理效果。试验结果表明,在进水流量为0.8m^3/d、水力停留时间为1.5d时,该工艺对浊度、CODMn、UV254、TN和NH4^+-N的平均去除率分别为93.71%、43.19%、17.69%、49.15%和48.92%。潜流人工湿地对原水预处理效率较高,运行稳定,可以有效减轻后续工艺的处理负荷。

关 键 词:潜流人工湿地  原水  预处理  效能

Abstract:In order to improve the inflow water quality and mitigate the loads of water treatment processes,a subsurface-flow constructed wetland was used to pretreat the raw water of waterworks.Using the Songhua River as the raw water source,the removal of turbidity,CODMn,UV254,TN and NH+4-N in the subsurface-flow constructed wetland was investigated.The results show that when the inflow rate is 0.8 m3/d and the hydraulic retention time(HRT) is 1.5 d,the average removal rates of turbidity,CODMn,UV254,TN and NH+4-N in...
Keywords:subsurface-flow constructed wetland  raw water  pretreatment  efficiency
