中文摘要:
      将筛选所得耐污能力强的栅藻作为研究对象,研究不同光质条件对栅藻处理沼液的影响,并且以实际沼液废水中NH4+-N、Cu2+浓度为参照设置不同浓度,分别考察NH4+-N、Cu2+对栅藻生长的影响。结果表明:在白光、蓝光、红光3种光质下,栅藻生物产率分别是0.21、0.04、0.03 g ·L-1·d-1,白光条件下栅藻生长相对较好。50 mg·L-1低浓度NH4+-N下栅藻生长较好,其生物产率优于BG 11培养基,分别为0.20、0.18 g·L-1·d-1;500、2000 mg·L-1高浓度NH4+-N下,藻细胞生长缓慢,生物产率仅为0.12、0.11 g·L-1·d-1。在Cu2+浓度分别为0.5、1.0、2.0 mg·L-1的培养液中,藻细胞生物产率分别为0.18、0.15、0.13 g·L-1·d-1。一定浓度NH4+-N存在下,栅藻能耐受较高的Cu2+浓度。
英文摘要:
      In this study, a strain of Scendesmus dimorphus with strong anti-fouling property was selected to investigate the effects of light qualities on the growth of Scendesmus dimorphus to treat swine wastewater. The growth of the algae based on standard concentrations of ammonia nitrogen and copper in swine wastewater was studied. The results showed that the growth of algal biomass in white light was better than that in blue and red light, with biomass productivity of 0.21, 0.04 g·L-1·d-1, and 0.03 g·L-1·d-1, respectively. The growth of the algae at low ammonia nitrogen concentration of 50 mg·L-1 was similar to that of the control, with biomass productivity of 0.20 g·L-1·d-1 and 0.18 g·L-1·d-1, respectively. However, the growth of the algae was influenced by high concentrations of ammonia nitrogen(500 mg·L-1 and 2000 mg·L-1) with biomass productivity of 0.12 g·L-1·d-1 and 0.11 g·L-1·d-1, respectively. In addition, the growth of Scendesmus dimorphus was influenced by copper, with biomass productivity of 0.18, 0.15 g·L-1·d-1, and 0.13 g·L-1·d-1 at copper concentrations of 0.5, 1.0 mg·L-1, and 2.0 mg·L-1, respectively. The algal cell can be resistant to high concentrations of copper when ammonia nitrogen co-exists in the medium.
