改进型波形潜流人工湿地处理猪场废水
Swine wastewater treatment with improved wavy-subsurface -flow -constructed-wetland
摘要
Abstract
An improved wavy subsurface flow constructed wetland(IW-SFCW) was proposed.The effect of this wetland system on the treatment of swine wastewater in five hydraulic retention time(HRT) was studied.The results showed that: COD,TP,TN and NH+4-N of swine wastewater can be removed well with this system.In the HRT 4 d,influent COD,TN,NH4 +-N,TP concentrations were 511 mg/L,120 mg/L,110 mg/L,10 mg/L or so,the removal efficiencies of COD,NH+4-N,TN and TP were 86.0%,54.4%,70.1% and 91.6%,respectively.Besides,the removal efficiency of COD and TP improved gradually with the HRT extension.In the best adapt HRT 8 d,the removal efficiencies of COD and TP reached 92.7% and 96.8%,respectively.But the removal efficiency of TN and NH+4-N increased firstly and then decreased with the HRT extension.In the best adapt HRT 4 d,the removal efficiencies of TN and NH+4-N in the wetland system were 54.4% and 70.1%,respectively.关键词
