摘　　要：基于正交试验和沿程水质检测,优化倒置A2/O处理低C/N污水工艺参数,分析各单元沿程物质流情况。结果表明,工艺参数优化:水力停留时间10h,回流比200%,污泥龄14d;缺氧池和厌氧池对COD去除量的贡献率为65.0%,好氧池对TP去除量的贡献率为79.3%,缺氧池对TN的去除量的贡献率为12.4%,缺氧池和好氧池对氨氮转化量的贡献率为75.4%。研究结果可为污水处理厂日常参数调控和优化提供实验室依据。Based on Orthogonal test and water quality detection,the process parameters of inverted A2/O for low c/n wastewater treatment were optimized,and the material flow of each unit was analyzed.The results show that the optimal process parameters are:hrt 10h,reflux ratio 200%,SRT 14d.In anoxic and anaerobic the contribution rate of COD removal was 65.0%,that of aerobic ponds to TP removal was 79.3%,that of anoxic ponds to TN removal was12.4%,and that of anaerobic ponds and anoxic ponds to ammonia nitrogen conversion was 75.4%.The results of this study can provide a laboratory basis for the regulation and optimization of daily sewage treatment parameters.
