摘要
采用内循环生物流化床系统，通过控制曝气时间和溶解氧浓度，能同时脱氮除磷。含氤、磷进水COD为352～1048mg／L，总氮（TN）为46．9—76．4mg／L，总磷（TP）在5．8—14．4mg／L时，COD、总氮（TN）、总磷（TP）去除率分别为92％、80％、93％，出水可达到国家二级排放标准。
The treatment of nitrogen and phosphor waste water by using inner loop fluidized bed reactor are studied. Performances of removal N and wiping off P are attained by controlling volumetric gas time and concentration of dissolved oxygen. The removal efficiencies of COD, TN and TPcan reach up to 92%, 80% and 93% when the influent of COD ,TN and TP reached 352 - 1 048 mg/L,46.9 - 76.4 mg/L,5.8 - 14.4 mg/L respectively. The targets of the treated waste water can achieve to the waste water discharge standard Ⅱ in China.
