摘要
Abstract
The pollutants removal effect and microfauna population dynamic change of humus soil SBR process were investigated and compared with traditional SBR process.The results showed that the humus soil SBR process improved TP removal efficiency,the effluent of TP was 0.44mg/L,the removal rate was 97.07％,while that of traditional SBR process was 2.40mg / L and the removal rate was only 84.02％.TN removal efficiency has little difference,the traditional SBR and humus soil SBR processes were 62.97％ and 69.15％,respectively.Because the humic acid precipitate out from the humus soil,the UN254 value was higher than that of the SBR process,resulting in the COD effluent concentration of the humus soil SBR process 10mg/L higher than the traditional SBR process.Microscopic examination of activated sludge indicated that activated sludge microfauna numbers in humus soil SBR process slightly less than in the traditional SBR process,may caused by actinomycetes in humus soil reactor.The correlation analysis between microfauna density and effluent quality and sludge characters showed that the density of microfauna was negatively correlated with SVI,SS,TN and COD removal rates.And the correlation between the metazoan and the SVI was higher than that of the traditional SBR process.关键词
