摘要
本试验采用混凝 -A/O系统组合工艺处理二步法腈纶废水 ,该系统处理效果良好 ,出水水质符合排放标准 ,可直接排入水体。A/O系统试验装置总容积 80L ,水力停留时间 5 8— 70h ,缺氧池与好氧池的容积比为 1∶3 ,回流比 ( 2—3 )∶1,COD和BOD总去除率分别约为 84%和 98%。
This experiments dispose of the wasterwater from acrylic fibres production with two steps in coagulation-A/O combined technics, this system works efficiently, the effluent water fits for discharge standard, and can be discharged into water system directly Equipment of A/O experiment is about 80 litre, hydrodynamic retention times vary from 58 to 70 hours, the rate of anoxia unit volume and oxidation unit volumn is 1∶3, circumfluence rate vary from 2 to 3,and the removal rates of COD and BOD are about 84% and 98% respectively
