【摘要】 采用序半连续反应器就新鲜废水中COD/N比对COD、氮化合物去除效率和微生物生长的影响进行了研究。结果表明,新鲜废水中的COD/N比对COD和总氮去除率有明显的影响。当COD/N比由2.5增至12.5时,COD去除率由44.0%增至75.8%,总氮去除率从63.4%增至99.8%,然而,加料废水中COD/N比对微生物生长没有明显的影响。用一组涉及多个微生物反应的动力学模型,分析了COD/N比对同时去除碳、氮化合物效率和微生物生长的影响。

【Abstract】 Impact of COD/N values of feed wastewater on COD, nitrogen removal and biomass growth in a sequencing fed batch reactor (SFBR) operation was investigated. Results indicated that COD/N ratios strongly influenced the later COD and total nitrogen removal efficiency. COD removal efficiency changed from 44.0% to 75.8% and total nitrogen removal efficiency increased from 63.4% to 99.8% at COD/N from 2.5 to 12.5. However variable COD/N ratios of feed wastewater are not marked for biomass growth. Multiple microbial reactions involved in the simultaneous removal process of carbonaceous and nitrogenous components in SFBR system were analysed using a set of kinetics mathematical model.
