摘　　要：宁波乐金甬兴化工有限公司丙烯腈-丁二烯-苯乙烯三元共聚物（ABS树脂）生产装置的日产污水量为2200t。改造前，装置排水中NH3-N含量为50～120mg／L，CODCr含量为130～150mg／L。通过对气浮系统改造，预处理排水CODCr，由7500mg／L降至4000mg／L；采用A／O工艺及内回流方式对二级生化-吸附再生系统进行改造，生化池处理效率高于98％，排水中CODCr，含量为50～80mg／L，NH3-N含量为0～2mg／L，二者去除率分别为99．6％，99．9％。2 200t/d wastewater from acrylonitrile - butadiene -styrene terpolymer unit was treated with treatment process. Before modification, NH3 - N and CODcr in the treated water were 50 - 120 rag/ L, 130 -150 mg/L respectively. After the air floating system reformed, CODcr in pretreated water was decreased from 7 500 mg/L to 4 000 mg/L. The biochemistry - adsorption regeneration system was revamped with A/O technology and inner reflux mode, and the efficiency of biochemistry treatment pool was more than 98% , the CODcr and NH3 - N in the ultimate drainage were 50 - 80 mg/L, 0 - 2 mg/L respectively.
