摘要
针对农村生活污水的特点,结合厌氧折流板反应器和厌氧生物滤池的优势,开发出一种强化厌氧反应器,并对其结构和参数设计进行优化。在厌氧折流反应区格室数量为4个、上下流格室宽度比为3∶1,厌氧生物滤池反应区滤料为陶粒-砾石、填充率为45%的条件下,强化厌氧反应器达到最佳的处理效果。介绍了复合厌氧技术应用于北京市通州区某村庄生活污水处理的工程案例,处理规模为3 m^(3)/d,出水水质达到北京市《农村生活污水处理设施水污染物排放标准》(DB 111612—2019)的新(改、扩)建三级标准,工程运行成本为0.73元/m3,可为小水量农村生活污水的原位处理提供技术依据。
According to the characteristics of rural domestic sewage,this paper developed an enhanced anaerobic reactor and optimized its structure and design parameters based on the advantages of anaerobic baffled reactor and anaerobic biofilter.The optimal removal performance of the enhanced anaerobic reactor was obtained when the number of chambers in the anaerobic baffled reaction area was 4,the width ratio of upstream to downstream was 3∶1,the packing media in the anaerobic biofilter were ceramsite and gravel,and the filling rate was 45%.The application of the composite anaerobic technology for the treatment of domestic sewage in a village in Tongzhou District,Beijing was introduced.The treatment scale of the project is 3 m^(3)/d.The effluent quality meets the level 3 limit for new construction,reconstruction and extension projects in Beijing specified in Discharge Standard of Water Pollutants for Rural Sewage Treatment Facilities(DB 11/1612-2019).The operational cost of the project is 0.73 yuan/m3.The project can provide technical basis for the in‑situ treatment of small‑scale rural domestic sewage.
