摘要：

本研究对天津高新区海泰南北大街景观河进行了水质评测，水体呈严重富营养化状态，整体处于地表水劣Ⅴ类水质。系统分析了河道水华现象的成因，水体中氮、磷含量高是引发水华现象的主要原因。针对性地制定了膜曝气生物膜反应器（MABR）生物修复方案，设计研发了适于河道的水草式MABR膜组件及其水体修复系统。通过对海泰南北大街景观河连续5个月的水质监测与观察，结果表明：MABR生物修复系统有效地提高了华苑景观河水体的自净能力，河道水体的氨氮、总磷、COD指标均达到《地表水环境质量标准》（GB3838-2002）III类或Ⅳ类标准，总氮含量达到V类，运行期间未发生藻类水华现象。MABR技术在河道水体修复方面具有广泛应用前景。

In this study, the water quality of Haitai North-South Street Landscape River was evaluated to be eutrophication and the water quality was worse than the surface water environmental quality standard (GB3838-2002) V. The increase of nitrogen and phosphorus content was the main factor that causing the river water blooms. Aiming at the existing problem, membrane aerated biofilm reactor (MABR) bioremediation solution was put forward. Aquatic plants type MABR membrane component and water body bioremediation system were designed. Afterwards, the MABR system was continuously operated and monitored for 5 months. The results indicated that the MABR bioremediation system significantly improved the self-purification capacity of Haitai North-South Street Landscape River. In the treated river water, the NH3-N, COD and TP concentrations met the surface water environmental quality standard (GB3838-2002) III or IV and the TN concentration met the surface water environmental quality standard (GB3838-2002) V. The algal bloom was not observed in the entire operating period. Thus, MABR technology has wide application prospect in river water bioremediation.
