增刊 2004年12月 生物修复技术在湖泊富营养治理中应用 刘军 1 李开明 2 刘斌 1 (1广州市恒兆环境生物工程有限公司 2国家环保总局华南环境科学研究所) 摘要：利用生物修复技术原理，通过藻类营养阻隔、促进富营养化湖泊藻类死亡；通过湖泊人工增氧造流，底泥生 物氧化技术，藻类微营养调节，强化水体和底泥好氧微生物生长，促进死亡藻类分解，降低水体藻类数量，提高水 体藻类多样性指数，恢复水体生态平衡。利用该技术，成功治理了上海静安公园、南京总统府公园等城市富营养化 湖泊。实践证明，藻类营养阻隔技术和其它生物修复技术，操作简单，效果显著，既可作为独立的技术单元，用于 城市水景的应急处理，也可和生物操纵技术、人工湿地、水生植被恢复等结合起来，应用于湖泊富营养化治理，达 到治标和治本的目的。 关建词：藻类营养阻隔 生物修复 湖泊富营养化 藻类微营养调节 1 2 1 The Application of Bioremediation in control of eutrophic lakes / Liu Jun , Li Kaiming , liu bin 1 2 (Guangzhou HengZhao Environmental Biological Engineering CO.,LTD ,Guangzhou 510300 Southchina Institute for Environmental Sciences, SEPA, Guangzhou 510655 ) Abstract： Using the principle of bioremediation , to control excess algae blooms by algae nutrition blocking in eutrophic lakes, to enhance the development of the aerobic microorganism which lived in water and sediment , speed the decomposition of the dead algae , decline the amount of the algae in the water , increase the diversity of the algae and resume the ecological balance of the water by increasing oxygen, artificial making fluidity of water、 and biologic oxidation of sediment. By using this technology we had renovated the lakes successfully in the JingAn park in Shanghai and Zongtongfu park in Nanjing and the other urban eutrophic lakes. It has been proved that algae nutrition blocking and other bioremediation are efficient and simple to operate. not only can be use as a lone technical unit in emergency treatment i
