Abstract:
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 m3/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.
