【摘要】：以产油藻类栅藻、小球藻为研究对象,通过贴壁方式考查微藻处理养猪沼液废水的效果。结果表明,栅藻、小球藻均能在沼液中较好生长,其生物产率分别是6.26、6.08 g·m~(-2)·d~(-1),与在正常培养基上(BG11)相当。栅藻、小球藻在沼液中培养,藻细胞油脂积累分别占细胞干重的34.6%和31.4%,与正常培养基相差不大。栅藻、小球藻均能较好净化废水中主要污染指标氨氮(NH_3-N)、总磷(TP)及化学需氧量(COD),栅藻的去除率分别是96.59%、74.52%和72.47%,小球藻去除率分别是94.90%、73.55%和71.40%。本研究将产油微藻培养和养猪沼液废水处理相结合,研究结果可为藻类生物燃料生产及沼液废水资源化利用等提供理论基础。
[Abstract]:The effect of microalgae on the treatment of pig biogas wastewater was investigated by means of adhering to the oil algae and Chlorella vulgaris. The results showed that both Chlorella spp and Chlorella spp could grow well in biogas liquid, and their biological yields were 6.26o6.08g m-2 d-1, which were similar to those on normal medium (BG11). When chlorella and chlorella were cultured in biogas, the accumulation of oil accounted for 34.6% and 31.440% of the dry weight of the cells, respectively, which was not different from the normal medium. The removal rates of ammonia nitrogen (NH_3-N), total phosphorus (TP) and chemical oxygen demand (COD),) were 96.594.52% and 72.47%, respectively. The removal rates of Chlorella vulgaris were 94.90% and 71.40%, respectively. In this study, oil microalgae culture was combined with pig biogas wastewater treatment. The results provided a theoretical basis for algae biofuel production and utilization of biogas wastewater.
