摘要：
针对腈纶废水的难降解问题，实验以一级A/O 的出水为研究对象，选用改进型组合式A/O 作为二级强化处理工艺。考察了水力停留时间、葡萄糖及碳酸氢钠的投加量等因素对二级A/O 工艺处理效果的影响。研究结果表明，当二级O 池的停留时间为24 h 时，对COD 的去除率可达16%，对氨氮的去除率可达36%；以葡萄糖为药剂，当葡萄糖的投加量为0.25 g/L 时，出水COD 可降至204 mg/L；以碳酸氢钠为药剂，当碳酸氢钠的投加量为0.25 g/L时，出水氨氮可降至20 mg/L。说明处理腈纶废水有必要增加强化处理工艺。

Abstract:
For the difficult degradation problem from acrylic fiber wastewater,taking the effluent of the one grade A/O as the study object,the improved and combined A/O is used as the two grades strengthened treatment process.The effects of HRT,glucose and sodium bicarbonate dosages on the two grades A/O process are investigated.According to the experiment results,when the HRT of two grades A/O is 24 h,the COD removing rate can reach 16%,and NH4+-N removal rate can reach 36%.When glucose is used as the chemical,whose dosage is 0.25 g/L,the effluent COD goes down to 204 mg/L.When sodium bicarbonate is used as the chemical,whose dosage is 0.25 g/L,the effluent NH4+-N is below 20 mg/L.
