摘要
随着我国大力实施乡村振兴战略,农村生活污水治理不断推进.本研究基于A2/O一体化设备处理农村生活污水的调试数据,考察DO浓度、硝化液回流比、污泥回流比等参数对工艺的影响,分析各参数相互影响规律,探究最佳运行参数.研究结果表明:A2/O工艺处理农村生活污水最佳运行参数应控制DO浓度区间2～3 mg/L,硝化液回流比200％,污泥回流比100％.调控最佳工艺参数后,经处理后,出水满足《农村生活污水集中处理设施水污染物排放标准》(DB33/973-2021)表 1中的一级标准,对A2O一体化设备在农村生活污水治理中的应用提供案例支撑和经验借鉴.
Abstract
With the vigorous implementation of the rural revitalization strategy in China,the treatment technology of rural domestic sewage has been continuously developing.Accroding to the experimental data of integrated A2/O equipment for rural domestic sewage treatment,this study investigated the impact of DO concentration,nitrifying liquid reflux ratio,sludge reflux ratio and other parameters on the sewage treatment process,analyzed the mutual effects of different parameters on the treatment,and explored the best operating parameters.The results showed that the optimal operation parameters of A2/O process for rural domestic sewage treatment should control DO concentration in the range of2～3 mg/L,nitrifying liquid reflux ratio of 200％,and sludge reflux ratio of 100％.After adjusting and controlling the optimal process parameters for sewage treatment,the effluent meets the Class I standard in Table 1 of the Discharge standard of water pollutants for centralized rural sewage treatment facilities(DB33/973-2021),providing case support and reference for the application of A2O integrated equipment in rural domestic sewage treatment.
