摘要
采用曝气生物滤池 生物活性炭工艺对炼油厂二级处理出水的深度处理进行中试研究 ,拟探索炼油厂废水深度处理用于循环冷却水补水新工艺 .结果表明 ,当进水COD浓度小于 1 30mg/L ,BAF滤速低于 4 2 4m/h条件下运行时 ,该工艺平均出水COD浓度小于 5 0mg/L ,平均出水浊度为 4 4 6NTU ,同时对NH+4 N也有一定的去除作用 .
To find a new advanced technology for wastewater reuse in refinery processing factory, a pilot test using BAF-BAC process was carried out. The results revealed that when the COD concentration of the influent was less than 130mg/L and BAF filtration rate was lower than 4.24m/h, the average effluent COD concentration of BAF-BAC process was less than 50mg/L, average turbidity was 4.46 NTU. At the same time this process has some effective removal rate on ammonia-nitrogen.
