| 摘 要： | 工业废水中往往含有有毒、难降解有机污染物,生物处理很难达到理想的效果,通常需与物化法联用.通过研究高铁酸钾对微生物生长代谢的影响,以期为高铁酸钾氧化法与生物处理法在同一反应器中实现提供有用参数.首先研究了高铁酸钾对微生物生长的影响,结果表明高铁酸钾浓度小于60mg/L时在微生物生长阶段的停滞期初期就分解完全,低浓度高铁酸钾对微生物生长没有不利影响甚至具有促进作用.然后考察了高铁酸钾对CODCr去除率和污泥理化特性的影响,结果表明高铁酸钾浓度为41.5mg/L时,CODCr去除率达到最大值,该浓度下,污泥的沉降性变好,与不加高铁酸钾的情况相比,SV值较低,MLSS和MLVSS明显增加.
