新型填料生物膜法处理城市污水的试验研究

利用新型天然生物质植物中空纤维填料生物膜反应器对城市生活污水处理进行了小试研究。在同等条件下，与传统球形聚乙烯填料生物膜反应器相比，新型填料生物膜反应器挂膜效率提高了78.57%。进入稳定运行期间，新型生物质填料生物膜反应器对COD、NH3-N、TN、TP的平均去除效率分别达到了77.75%、94.78%、71.01%和79.91%，明显高于传统填料生物膜反应器的处理效果。

Experiment on Wastewater Treatment by a New Sequencing Biomass Biofilm Reactor

A new kind of biomass media was utilized in a biofilm reactor for the wastewater treatment. Under similar experimental conditions, the biofilm formation efficiency of the new biomass reactor had improved by 78,57 % compared to the traditional spherical polythene filter biofilm reactor. During the steady operation period, average removals of COD,NH3-N,TN and TP in the new biomass biofilm reactor were 89.32%, 94.71%, 65.56% and 81.74%, respectively, which were obviously better than those of the traditional filter biofilm reator.
