摘　　要：针对小规模畜禽养殖废水存在的污染重、治理难等问题,采用SBR+人工湿地组合工艺,处理低浓度的小规模畜禽养殖废水。通过调整水力停留时间(HRT)、有机负荷,研究同步脱氮除磷效果。结果显示,出水COD、NH_(4)^(+)-N、TP的去除率稳定在90%、95%、95%左右,TN去除率较低;最佳HRT为12h;反应器具有一定的抗冲击能力,但高有机负荷时TN去除率下降;反应器出水接入人工湿地后,出水COD降至12mg/L,TN降至2.5 mg/L,满足《城镇污水处理厂污染物排放标准》(GB 18918-2002)一级A排放标准。研究表明,该组合工艺高效节能、占地小、投资和运行费用低,可为小规模畜禽废水处理提供参考。The pollution and difficulty in treatment of small-scale livestock and poultry wastewater pose significant challenges.In this study,an SBR artificial wetland combination process was employed to treat low-concentration small-scale livestock and poultry wastewater.The simultaneous denitrification and phosphorus removal effect were investigated by adjusting the hydraulic retention time(HRT),organic load,and carbon-nitrogen ratio.The results showed that the removal rates of COD,NH_(4)^(+)-N,and TP in the effluent remained stable at around 90%,95%,and 95%,respectively,while the TN removal rate was relatively low.The optimal HRT was found to be 12 hours.The reactor exhibited a certain shock resistance,but the TN removal rate decreased under high organic loads.After the effluent from the reactor was discharged into the artificial wetland,the effluent COD decreased to 12 mg/L and TN decreased to 2.5 mg/L,meeting the first-grade A discharge standard of the“Pollutant Discharge Standard for Urban Wastewater Treatment Plants”(GB 18918-2002).This combined process is efficient,energy-saving,occupies a small footprint,and has low investment and operating costs,providing a reference for the treatment of small-scale livestock and poultry wastewater.
