摘要:
开发了一种将物理过滤和生物处理相结合的水生植物滤床(APFB)技术.在太湖陈东港入湖口处进行APFB处理河水的试验结果表明,APFB的最佳水力负荷为4.0 m3/(m2·d),此时总氮、总磷和叶绿素a的去除负荷分别为1.3,0.25 g/(m2·d)和170 μg/(m2·d),相应的去除率分别为28%,50%和73%; 总氮、总磷和叶绿素a的去除负荷随原水质量浓度的增加而增大; APFB的硝化作用高于反硝化作用.研究证明APFB技术净化富营养化地表水具有高效、低成体的特点.
Abstract:
Aquatic plant filter bed(APFB)is developed that combines physical filter and biological treatment. A pilot scale APFB established at the entrance of Chendonggang River into Taihu Lake was tested to treat polluted river water. Results show that the removal loading rates of total nitrogen(TN), total phosphorus(TP)and chlorophyll-a(Chl-a)are 1. 3,0. 25 g/(m2·d)and 170 μg/(m2·d), respectively, under the optimal hydraulic loading rate of 4. 0 m3/(m2·d), the removal efficiencies are accordingly 28%,50% and 73%. The removal loading rates of TN, TP and Chl-a all increase with inflow concentrations. The effect of nitrification is better than that of denitrification in APFB. This study indicates that APFB is a low cost technique with high removal rate for hyper-eutrophic surface water purifying.
