- 摘要:
- 针对上海市嘉定区某农村生活污水处理站的出水水质由《城镇污水处理厂污染物排放标准》（GB 18918—2002）的二级标准提升至上海市《农村生活污水处理设施水污染物排放标准》（DB31/T 1163—2019）的一级B标准的需求，通过工艺重构实施提标改造：保留原有生物滤池及人工湿地主体结构，新增调节/缺氧池、接触氧化池与高效澄清池，构建“调节/缺氧池+生物滤池+接触氧化池+高效澄清池+人工湿地”处理工艺。改造后系统出水COD、SS、NH3-N、TN及TP分别为19.0~26.0、5.0~9.0、1.9~3.6、9.6~14.3、0.4~0.7 mg/L，平均去除率分别达到72%、90%、85%、64%和78%，出水水质满足上海市一级B标准。该污水处理站改造后运行稳定高效，脱氮除磷能力增强，对低浓度农村生活污水具有良好的适应能力，且运行费用仅约0.60元/m3。
- Abstract:
- To meet the requirement of upgrading the effluent quality of a rural domestic sewage treatment station in Jiading District of Shanghai, from second level standard of Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant(GB 18918-2002) to first level B standard of Discharge Standard of Water Pollutants for Rural Sewage Treatment Facilities (DB31/T 1163-2019) in Shanghai, this study implemented a retrofitting process through technological reconfiguration. While retaining the main structures of the original biological filter and constructed wetland, new units, including equalization/anoxic tank, contact oxidation tank, and high-efficiency clarifier, were constructed, forming a treatment process as equalization/anoxic tank, biological filter, contact oxidation tank, high-efficiency clarifier, and constructed wetland. After retrofitting, the effluent concentrations of COD, SS, NH3-N, TN, and TP were measured as 19.0-26.0 mg/L, 5.0-9.0 mg/L, 1.9-3.6 mg/L, 9.6-14.3 mg/L, and 0.4-0.7 mg/L, respectively. The corresponding average removal rates reached 72%, 90%, 85%, 64%, and 78%, respectively. The effluent quality complied with the first level B standard in Shanghai. The upgrading system demonstrated stable and efficient operation, with enhanced nitrogen and phosphorus removal capabilities. It exhibited strong adaptability to low-concentration rural domestic sewage and maintained low operational costs of about 0.60 yuan/m3.
