Research on Pollutant Loading of Biological Aerated Filter

Abstract:

The aim of this study is to investigate the pollutant loading of two-stage biological aerated filter in series. We choose Shenyang Xiannhe wastewater treatment plant as research site. By testing pollutant loading under conditions of the same hydraulic loading and different hydraulic loading respectively, we discovered that there was great difference between the 1^st filter and the 2^nd filter. COD loading of the 1^st filter varied from 2.0 m^-3.d^-1 to 6.0 m^-3.d^-1,however NH₄-H loading was more complex with NH₄-H remove rate being negative in most cases . COD loading of 2^nd filter was from 0.2 m^-3.d^-1to 1.5 m^-3.d^-1,and NH₄-H loading was from 0.4 m^-3.d^-1 to 1.5 m^-3.d^-1. Key words: biological aerated filter;pollutant loading.
