摘要:
随着对农村污水治理的重视程度越来越高，农村污水处理设施需求量也在不断增加。为此，分析了一体化多级AO生物膜反应器处理分散式农村生活污水的效果，探讨了反应器的可行性及沿程处理效果。结果表明，在平均水温为15~28 ℃、硝化液回流比为100%、水力停留时间为10 h的运行条件下，该反应器出水COD、氨氮、总氮的平均浓度分别为30、5.74、31.55 mg/L，出水COD和氨氮浓度满足河南省《农村生活污水处理设施水污染物排放标准》（DB 41/1820—2019）一级排放标准，反应器抗COD、氨氮冲击负荷性能较好。并且该一体化污水处理装置运行费用低廉，约为0.30 元/m3。
Abstract:
The increasing importance of rural sewage treatment increases the demand for rural sewage treatment facilities. This paper analyzed the performance of integrated multistage AO biofilm reactor for the treatment of decentralized rural domestic sewage, discussed the feasibility of the reactor, and investigated the treatment efficiency along the process. When the average water temperature was 15-28 ℃, the reflux ratio of nitrification liquid was 100% and the hydraulic residence time was 10 h, COD, ammonia nitrogen and total nitrogen concentrations of effluent were 30 mg/L, 5.74 mg/L, 31.55 mg/L, respectively. The effluent COD and ammonia nitrogen met the first level limits specified in the local standard of Henan Province: Discharge Standard of Water Pollutants for Rural Sewage Treatment Facilities (DB 41/1820-2019), and the reactor showed good impact load resistance to COD and ammonia nitrogen. In addition, the integrated sewage treatment device had a low operating cost of approximately 0.30 yuan /m3.
