摘　　要：近年来随着我国合成革产业的飞速发展,合成革废水量也不断增多,利用传统生物脱氮工艺处理存在占地面积大、运行成本较高、总氮去除不彻底等问题,亟需探求经济高效的合成革废水脱氮新技术。本研究采用短程硝化(PNP)联合厌氧氨氧化/反硝化(Anammox/DN)处理实际合成革废水。实验结果表明,联合工艺处理效果较稳定,进水COD为160~580 mg/L,NH_4^+-N质量浓度为260~460 mg/L,出水NH_4^+-N质量浓度约15 mg/L、NO_2^--N质量浓度小于10 mg/L,NO_3^--N约30 mg/L,出水COD小于40 mg/L,总氮去除率稳定在85%左右,总氮容积去除速率约0.41~0.60 kg N/(m^3·d),达到预期处理效果。With the rapid development of synthetic leather industry in China, the generated amount of wastewater is also increasing in recent years. The traditional biological denitrification process has the problems of large area, high operation cost, and difficult to remove total nitrogen. The new process for synthetic leather wastewater treatment with economical and efficient was explored urgently. Partial nitrification （PNP） combined with anammox/denitrification （Anammox/DN） process for synthetic leather wastewater treatment was studied in this paper. The experimental results showed that, the treatment effect of combined process was stable, when influent COD and NH4＋-N mass concentration was 160--580 mg/L and 260-460 mg/L, respectively, the effluent NH4^-N, NOE--N, NO3--N and COD mass concentration was less than 15 mg/L, 10 mg/L, 30 mg/L and 40 mg/L, respectively. The total nitrogen removal rate reached 85% and total nitrogen volumetric removal rate was 0.41-0.60 kgN/（m3. d）, which reached expected treatment effect.
