| 摘 要： | 针对腈纶废水生化出水用传统脱氮工艺深度脱氮时碳源不足的问题,采用三级生物膜反应器作为深度处理装置,研究了反应器的启动及进水pH、水力停留时间(HRT)、进水氨氮(NH4+-N)浓度对NH4+-N去除率的影响并确定其最佳运行条件及最佳条件下总氮(TN)的去除效果.结果表明,在HRT为24 h,进水pH为7.8～8.0条件下反应器对NH4+-N和TN的去除效果最佳,平均去除率分别为94.6%和53%;且进水NH4+-N浓度对其去除效果没有明显影响;反应器在不投加有机碳源情况下,对TN有明显去除效果,平均去除率53%,最高去除率达66%,表明三级生物膜反应器深度处理腈纶废水时脱氮效果明显.

| Abstract: | To resolve the shortage of carbon source during traditional denitrification used to treat secondary effluent of acrylic fiber wastewater,tri-stage biofilm reactor was used,the influence of pH of influent, HRT, and NH4+-N concentration in raw water on NH4+-N removal was investigated. Efficiency of TN removal was also investigated. It demonstrated that the optimal HRT and pH were 24 hours and 7.8-8.0 respectively. Under these conditions the removal efficiencies of NH4+-N and TN were 94.6% and 53% respectively. And the removal efficiency of NH4+-N had no relationship with the concentration of the inflow water. With absence of organic carbon source in the reactor, efficiency of TN removal was obvious, the average and the highest removal efficiencies of TN were 53% and 66% respectively, efficiency of secondary effluent of acrylic fiber wastewater nitrogen removal was obvious when treated with Tri-stage biofilm reactor. |
