摘要
选取2019年太原市晋阳污水处理厂的出口在线监控数据,分析了全年处理量的变化规律和全年出水水质的变化特点,同时对该厂的两种不同的处理工艺进行了比较。结果表明:该厂的日处理能力相对稳定未超出设计处理能力,处理量的高峰出现在每年的夏季汛期和春节前后。AAO和MBR两种工艺对于生活污水的处理都相对稳定,出水中的COD、氨氮、总磷和总氮均能达到《城镇污水处理厂污染源综合排放标准》中一级A排放。但MBR要优于AAO在污染物的去除率上。
Based on the 2019 export monitoring data of sewage treatment in Jinyang,Taiyuan,the variation law of annual treatment capacity and the variation characteristics of annual effluent quality were analyzed.At the same time,two different treatment processes of the plant were compared.And it turns out that the plants relatively stable daily capacity does not exceed its designed capacity.The peak of processing volume appears in summer flood season and around spring every year.AAO and MBR process for domestic sewage treatment are relatively stable.The COD,ammonia nitrogen,total phosphorus and total nitrogen in the effluent can reach Comprehensive Emission Standards for Urban Sewage Treatment Plant 1A emissions.But MBR is better than AAO in the removal rate of pollutants.
