摘　　要：采用序半连续式反应器在不同的加料流率下,对人工合成废水营养物的去除进行了研究.氮化合物的去除是在一个操作循环中采用顺序进行硝化和反硝化反应,加料流率分别为0.05,0.10,0.15 L/h 3个不同的水平,不同的加料流率对COD,氮化合物(NH4-N和NO3-N)去除和微生物生长的影响进行了研究.结果表明,加料流率对COD、氮化合物(NH4-N和NO3-N)去除和微生物生长的都有一定的影响.当加料流率为0.05 L/h时,COD有最高去除率(84%)、最高的总氮去除率(64%),微生物的生长速率没有明显的影响.并利用一组涉及到多个微生物反应的动力学数学模型,分析了加料流率对同时去除碳、氮化合物率和微生物生长的影响.Nutrient removal from synthetic wastewater by sequencing fed-batch reactor （SFBR） was studied at different feeding rates. Nitrogenous substrate was removed by sequencing nitrification and denitrification in a cycle of SFBR operation. The feeding rates were kept at 0.05 L/h, 0. 1 L/h and 0.15 L/h, respectively. Effects of feeding rates on COD, nitrogenous compounds （NH4-N and NO3-N） removal efficiency were investigated. The results indicated that feeding rate effects on COD, total nitrogen removal and microbe＇s growth. The highest of COD （84%） ,total nitrogen （64%） removal efficiency were obtained at the feeding rate F = 0. 05 L/h. The multiple microbial reactions involved in the simultaneous removal process of carbonaceous and nitrogenous components in SFBR system were analyzed using a set of kinetic mathematical model.
