摘要
采用多孔高分子材料作为生物膜载体,探讨了生物膜SBR(BSBR)工艺的性能,并将其与传统活性污泥SBR进行了比较研究.BSBR工艺COD平均去除率为91.8%,SBR工艺COD平均去除率为89.6%.BSBR工艺系统对较低进水NH4+-N浓度有良好的适应性,且沉降性能优于SBR工艺,处理效果好.这些优势对提高间歇式操作模式的处理效率具有重要意义.
Taking porous multimolecular material as the carrier of bio-film, the performances of bio-film SBR （BSBR） and traditional activated sludge SBR were discussed and investigated by means of comparison between them. Mean removal rates of COD by using BSBR and SBR processing were 91.8% and 89. 6%, respectively. The BSBR processing system possessed fine adaptability to lower concentration of NH4^＋-N of the influent, superior sediment ability to that of SBR processing, and good processing effect. These superiorities are significant for improvement of processing efficiency with intermittent operation mode.
