Flow condition optimization of Algal Turf Scrubber and cost effectiveness analysis of engineering application

水体富营养化是全球性环境问题之一，我国湖库富营养化问题相当突出，亟需研发经济高效的生态工程技术用于生态修复。本文以福建省九龙江北溪江东库区（厦门、漳州水源地）富营养化水体为研究对象，设计小型藻坪净水系统（ATS），针对运行水流条件（水力负荷、间歇水流频次）开展试验，评估ATS的藻类生产率及氮磷去除速率（ATS效率），进而确定最优的水流条件。基于研究结果，设计规模化ATS（1ha）用于未来对江东库区富营养化水体的处理，评估三种工程方案的成本。 主要研究结果如下： （1）水力负荷影响ATS效率，水力负荷120LPMm-1时ATS藻类生产率和氮磷去除速率达到最高。设置60-180LPMm-1七组...Eutrophication is one of the global environmental problems, and eutrophication of lakes and reservoirs in China are quite prominent. There is an increasing demand for economic and effective ecological engineering to restore aquatic ecosystems. Jiulong River (Jiangdong reservoir) was selected as the study site, Jiulong River is the drinking water source of Xiamen and Zhangzhou. In this study, an ...学位：理学硕士院系专业：环境与生态学院_环境管理学号：3312014115172
