| 中文摘要 |
| 工业废水污染日趋严重,水体中重金属钴污染因难处理、高危害等问题成为废水净化的关键.传统治理重金属工业废水的方法难以应用.为寻求处理工业废水"绿色生态"可行性路径,本文以葡萄藻Botryococcus braunii SAG 807-1为研究对象,应用贴壁培养技术对含钴工业废水进行处理研究.结果表明,葡萄藻贴壁培养可处理工业废水,4.5 mg·L-1 Co2+对葡萄藻生长影响不大,却可以促进长链烃类的合成,提高烃产量.葡萄藻贴壁培养去除Co2+的能力为1473.9μmol·g-1,远高于报道的微藻P.littoralis.本研究为绿色高能燃料烃类的生产与工业废水处理耦合提供理论基础. |
| 英文摘要 |
| Industrial wastewater pollution is an increasing problem. The wastewater infiltrated cobalt is a key to purify wastewater because it is seriously hazardous and hard to treat. Traditional management method of heavy metals in industrial wastewater is difficult to apply. To seek for "green ecological" feasible approaches of industrial wastewater treatment, this paper studied the effect of industrial wastewater containing cobalt on the growth and hydrocarbon accumulation of Botryococcus braunii SAG 807-1 with biofilm attached cultivation. The research results obtained were as follows:B.braunii with biofilm attached cultivation could treat industrial wastewater, and 4.5 mg·L-1 cobalt could accelerate the accumulation of hydrocarbon while having little influence on the growth of B.braunii, the ability of B.braunii with biofilm attached cultivation to remove Co2+ from industrial wastewater was 1473.9 μmol·g-1, which was much higher than the report of P. littoralis culture. Through the study in this paper, the theoretical basis for the coupling of production of green high energy fuel hydrocarbon and industrial wastewater treatment was established. |
