At the 35th d, the removal of NH4+-N, COD, Ca2+, and PO43--P were 94.71, 50.55, 80.68, and 76.67%, respectively. The SEM results showed that the LS/PEI@biochar biocarrier had rough surface and superior biofilm suspension performance. Furthermore, SEM, FTIR, and XRD analysis confirmed that PO43--P was removed by adsorption and co-precipitation. The establishment of LS/PEI@biochar biofilm reactor provided a new solution for the treatment of oligotrophic water complex pollution.

在第35天时，氨氮（NH4+-N）、化学需氧量（COD）、钙离子（Ca2+）与正磷酸盐磷（PO43--P）的去除率分别为94.71%、50.55%、80.68%及76.67%。扫描电子显微镜（Scanning Electron Microscopy，SEM）结果表明，LS/PEI@biochar生物载体表面粗糙，且具备优异的生物膜悬浮性能。进一步通过扫描电子显微镜（SEM）、傅里叶变换红外光谱（Fourier Transform Infrared Spectroscopy，FTIR）与X射线衍射（X-ray Diffraction，XRD）分析证实，正磷酸盐磷（PO43--P）可通过吸附与共沉淀作用被去除。LS/PEI@biochar生物膜反应器的构建，为贫营养水体复合污染治理提供了全新的解决方案。
