摘　　要：针对正通煤矿生活污水处理站废水碳源偏低、悬浮物含量不稳定的特点,以及出水水质要求的提高,采用"同步生物氧化池(SBOT)+微絮凝过滤"工艺对原系统进行提标改造。SBOT工艺具有生物量大、处理负荷高、可实现COD和氨氮同步去除等优点。运行结果表明,系统提标改造后出水COD、TN、氨氮、TP、SS的平均浓度为12.3、7.5、1.1、0.29、6.2 mg/L,出水水质稳定达到《陕西省黄河流域污水综合排放标准》(DB 61/224—2018)A要求,可满足绿化、道路冲洗、选煤厂生产补充及汽车冲洗要求。In order to treat the low-COD and unstable-SS wastewater in a domestic sewage treatment station of Zhengtong Coal Mine and meet the improved wastewater discharge standard,a process of "synchronous biological oxidation tank(SBOT) + micro flocculation filtration" was adopted to upgrade the original system.The SBOT process has the advantages of large biomass and high treatment capacity,and can simultaneously remove COD and ammonia nitrogen.The operation results show that the average concentrations of COD,TN,ammonia nitrogen,TP and SS in the effluent of the upgraded system are 12.3,7.5,1.1,0.29 and 6.2 mg/L.The effluent quality stably meets the requirements of integrated wastewater discharge standard of Yellow river basin in Shaanxi Province(DB 61/224—2018),as well as the requirements of greening irrigation,road flushing,water supply of coal preparation plants and vehicle flushing.
