摘要
以四尾栅藻(Scenedesmus quadricauda)为材料、酿酒废水底锅水为培养基,探究栅藻对底锅水总磷、总氮、COD的去除情况,并对栅藻的成分进行分析。结果表明,在底锅水pH为6.0、质量分数为5%、四尾栅藻接种量为10%、光照强度为8 000 Lux时,培养6 d后COD降解率达到96.21%,总氮降低率为71.6%,总磷降低率为94.11%,培养液中藻生物量、油脂、碳水化合物含量均高于BG11标准培养基。该研究可为酿酒废水处理和微藻养殖的耦联提供实验基础。
Abstract
Using Scenedesmus quadricauda as the material and pot bottom wastewater from liquor-making as the culture medium to investigate the removal of total phosphorus, total nitrogen, and COD, and analyze the composition of S.quadricauda.The results show that the degradation rate of COD reaches 96.21%, total nitrogen decreases by 71.6%, and total phosphorus declines by 94.11% after 6 days of cultivation when pH is 6.0, pot bottom wastewater concentration is 5%, inoculation amount of S.quadricauda is 10%, and light intensity is 8 000 Lux.The contents of algal biomass, oil grease, and carbohydrates in the cultivation solution are all higher than those in the BG11 standard medium.This study can provide an experimental basis for the coupling of liquor-making wastewater treatment and microalgae cultivation.
