Abstract:

Constructed Intensified Biological Bed (CIBB) is a new sewage disposal technology based on subsurface flow constructed wetland and biological aerated filter. The CIBB was applied for serious polluted transboundary river water. The removal rates of pilot scale CIBB on simulated Tiaozi River system CODcr、NH₃-N and TN were over 70%, 90%, 60% respectively. The hydraulic loading of CIBB reached 4.8m•d^-1, and CODcr organic loading was 185g•(m³d) ^-1 and the ammonium loading was 19 g•(m³d) ^-1. If the CIBB is used on the Tiaozi River, CODcr and ammonium in outflow of CIBB system will reach class V standards of Environmental quality standard for surface water (GB3838-2002).
