| 英文摘要 |
| A comparative performance between porous polymer carriers (HP) and granular activated carbon carriers (GAC) in anaerobic fluidied bed reactors was undertaken to evaluate their characters.The results showed that the COD removal and the biogas volume yield rate were 84% and 16.5 m3/(m3·d) respectively when HP was used as carrier to treat synthetic wastewater,at the top COD organic load rate of 65.5 kg/(m3·d),however those were 74.2% and 14 5% respectively for GAC carrier at the top load rate of 63.25 kg/(m3·d).The COD removal and biogas volume yield rate were 64.7%～54.5% and 1.89～2.7 m3/(m3·d) respectively when HP was used as carriers to treat straw pulping wastewater,at the load rate of 14.5～36.15kg/(m3·d),and those were 61.0%～52.1% and 0.73～2.0m3/(m3·d) respectively for GAC carriers at the load rate 9.16～19.06kg/(m3·d).The study revealed that the HP carriers reactor is more efficient than the GAC carriers reactor in microbial immobilization and the wastewater treatment. |
