利用沼气废液培养螺旋藻
Cultivation of Spirulina in Biogas Wastewater
摘要
Abstract
[Objective] The aim was to obtain the way to cultivate Spirulina in biogas wastewater. [ Method] The cultivating technology of Spiruli-na in the biogas wastewater was obtained by adding certain proportion of Zarrouk culture to the wastewater, and the cultivating condition was optimized by the orthogonal experiment. The purification of the biogas wastewater by Spirulina was also studied by testing the changes of the concentrations of nitrogen and phosphorus in the wastewater during the cultivation of Spirulina. [Result] Spirulina could not grow directly in the biogas wastewater,but also could grow very well after adding 10% of Zarrouk culture to the wastewater. The orthogonal experiment showed that the best growing condition for Spirulina in the wastewater was pH 8,initial optical density 0.3 at 560 nm,illumination 5000 lx. The study also showed that Spirulina had good removal of the nitrogen and phosphorus in the wastewater. The elimination rates of active phosphorus,nitrate nitrogen and nitrite nitrogen by Spiruiina reached to 97.1% ,61.2% ,and 53.6% respectively. [Conclusion] It can be feasible to cultivate Spirulina in the biogas wastewater. The cultivation can not only purify environment,but also greatly cut the production cost of Spirulina,which would be an effective and economical way to the resource utilization of the biogas wastewater.关键词
