【摘要】 阐述了物理化学法和生物法在印染废水处理中的应用。通过实例介绍了厌氧水解+射流曝气+气浮回流+混凝气浮工艺,运行结果表明:在平均进水水质CODCr560mg/L,BOD5216mg/L,SS178mg/L,色度200倍的条件下,其去除率分别为86.5%、93.0%、81.0%和90.0%,出水水质可达到《广东省地方标准水污染物排放限值》(DB44/26—2001)中的一级标准。更多还原

【Abstract】 Application of physical and chemical process and biological process on treating dyeing wastewater is presented.A case adopting a composite process involving anaerobic hydrolysis and jet aeration and air flotation reflux and coagulant air flotation is taken.The running result shows that the removal rates of COD_Cr,BOD₅,SS and degree of turbidity are 86.5%,93.0%,81.0% and 90.0% respectively when the concentrations of them are 560mg/l,216mg/l, 178mg/l and 200 times respectively.The outflow water quality can reach the first class standard of Guangdong local standard（DB44/26-2001）.更多还原
