  • 摘要: 为探讨污水深度处理和同步获取产油微藻的可行性,建立光生物反应器,应用微拟球藻去除污水和中水中的氮磷,并分析不同浓度的Fe3+和Zn2+离子对微藻的生长和油脂积累的影响,从而在净化污水的同时培养微藻获得富油生物质。结果表明,该藻对污水氮磷具有较强的去除能力,可在13 d内,去除水体中96%的氨氮和94%的磷,同时化学需要氧量(COD)的去除率可达72.9%。在生活污水中培养至第16天,微藻的细胞密度可达4.55×106 cell/mL。Fe3+浓度对微拟球藻的生长具有显著影响(P6 cell/mL。该研究以中水和生活污水为基质培养微拟球藻,同时获取微藻油脂,为污水中氮磷的去除和能源的同步获取提供了新途径。
