酿酒废水培养钝顶螺旋藻(S.platensis)与营养物质去除的研究

Simultaneous Single-cell Production and Nutrient Removal Using Spirulina platensis in Brewing Process Wastewater

经前处理后的酿酒厂废水用清水稀释用来培养钝顶螺旋藻 ,可以获得高生物量的钝顶螺旋藻。同时 ,废水中的营养物质也可以被去除。在连续培养条件下 ,使用改进的开放式通道装置培养获得螺旋藻的蛋白质、水分、灰化成份分别为 6 2 .7%、6 .2 1 %和 5 .2 6 % ,重金属含量也符合标准 (GB 1 991 9-1 997)。T -N ,NH4 + -N ,T -P和PO4 3 --P的去除效率分别可达到 72 %、97.9%、4 1 .3%、4 3.1 %。

High biomass was produced and nutrient was removed when Spirulina platensis grew in pretreated brewhouse wastewater diluted by freshwater. Under continuous culture conditions using modified open raceway device, contents of protein,moisture and ash were 62.7%,6.21% and 5.26% for the algal powder respectively. Contents of some heavy metals accorded with the standard(GB 19919-1997). Removal efficiencies of T-N, NH 4 +-N, T-P and PO 4 3--P were 72%, 97.9%, 41.3% and 43.1%, respectively.
