| 摘 要： | 为了研究合成氨废水的有效处理工艺,以改进后的SBR工艺建立中试系统处理合成氨废水,系统考察了SBR工艺运行的最优参数以及工艺在稳定运行时COD,NH4^＋和TN的去除效果.结果表明：SBR工艺的最佳运行工况为进水（1.5h）→好氧曝气（运行时间9 h、曝气量80m～3/h）→缺氧搅拌（3h）→沉淀（50min）→出水（1.5h）,SBR工艺对COD,NH4^＋-N和TN的平均去除率分别为91%,87%和83%,去除效果显著,出水COD,NH4^＋-N和TN均达到GB 13458—2001《合成氨工业水污染物排放标准》的一级标准.

| Abstract: | Based on the traditional SBR,a new pilot SBR system was established for the treatment of a high-strength ammonia nitrogen wastewater in order to research the effective treatment process.The effects of the nitrogen removal were emphatically studied.The results show that the optimum operating parameters gained is as follow;the inflow time is 1.5 h,the aeration time is 9 h,the aeration rate is80 m^3 /h,the anaerobic stir time is 3 h,sedimentation time is 50 min,and the effluent time is 1.5 h.The SBR effluent meets the demands of the first class standard for synthetic ammonia industry wastewater of GB 13458—2001 ＂Integrated Wastewater Discharge Standard＂ when the removal rates of COD,NH4^＋-N and TN were equal to 91%,87%and 83%,respectively. |
