摘　　要：通过对不同上升流速下改进型EGSB和EGSB处理人工配置城市污水效果的比较研究,提出了一种更为有效的处理城市污水的反应器--改进型EGSB反应器,在上升流速为5.41m/h时,其出水的COD值稳定在60mg/L左右,出水SS明显要低于未改进的EGSB。同时还考察了运行期间改进型EGSB反应器内颗粒污泥的胞外多聚物、辅酶变化等,在高的上升流速下,改进型EGSB反应器中颗粒污泥的胞外多聚物含量和辅酶F420含量比未改进EGSB中的要高。Through comparison of treatment efficiency in expanded granular sludge bed(EGSB)and modified EGSB at different upflow velocity,modified EGSB was proposed to treat urban wastewater of low concentration with higher removal efficiency and stability.At upflow velocity of 5.41m/h,COD of effluent in modified EGSB was about 60mg/L and SS was lower than that in EGSB.Biological characteristics variety of granular sludge was also studied,at the higher upflow velocity,the content of ECP and coenzyme F420 in granular sludge in the modified EGSB is more than that in EGSB reactor.
