摘要:
以长沙市某小区17户居民灰水处理项目为例，采用水解酸化+A2O+MBR复合工艺技术构建分散式一体化污水处理系统，并分析了该系统2024年的运行效果、建设及运维成本。结果表明，系统对COD、BOD?、SS、氨氮、总氮和总磷的平均去除率分别为94.02%、97.71%、96.06%、94.97%、79.49%和96.29%，出水水质可稳定达到《城镇污水处理厂污染物排放标准》（GB 18918—2002）的一级A标准，直接回用于小区园林绿化，总固碳量为2.85 tCO2/a。与传统处理模式相比，该项目建设成本降低约30%，运维成本降低约15.6%。
Abstract:
This study presents a decentralized integrated greywater treatment system constructed for 17 households in a residential community of Changsha. The system employs a hydrolysis acidification+A 2O+MBR hybrid process and evaluates its operational performance in 2024 along with the associated construction and maintenance costs. Results demonstrate stable treatment effects and significant economic advantages, providing practical insights for urban residential greywater recycling. Results showed that the system achieved annual average removal rates of 94.02% for COD, 97.71% for BOD5, 96.06% for SS, 94.97% for ammonia nitrogen, 79.49% for total nitrogen, and 96.29% for total phosphorus, consistently meeting the first level A standards of Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant(GB 18918-2002). The treated effluent was directly reused for landscape irrigation within the community, contributing to a total carbon sequestration of 2.85 tCO2/a. Compared with conventional approaches, this project reduced construction costs by approximately 30% and operation and maintenance expenses by around 15.6%.
