摘要
采用生物接触氧化法处理螺旋藻养殖废水的试验结果表明,在pH为6—9,水力停留时间为8h,曝气气水比为5:1的条件下,处理效果较好,废水中CODCr、SS、浊度、藻量的去除率分别达到69%、75%、76%、96%,且在处理过程中不添加对螺旋藻养殖有害的物质,经处理后出水可回用于养殖螺旋藻。
The results that excellent efficiency of treating wastewater from spiral algae culture by biological contact oxidation process show happens while pH is 6 to 9, dydraulic detention period is 8hr, and the rate of air and water during aeration period is 5 to 1. At this time, the removal rate of CODCr, SS, degree of turbidity, and the volume of algae can reach 69 %, 75 %, 76 % and 96 % respectively. Any harmful materials will not be added to the water of spiral algae culture, and the water outflow after treatment can be recycled.
