| 摘 要： | 采用内循环生物流化床系统,进行N、P废水的试验研究,通过控制曝气时间和溶解氧浓度,能同时达到脱氮除磷的效果.对于N、P废水,COD在352～1048 mg/L,TN在46.9～76.4 mg/L,TP在5.8～14.4 mg/L时,COD、TN、TP去除率分别为92%、80%、93%,处理后的水可达到国家二级排放标准.

| Abstract: | In the paper the study on nitrogen and phosphor wastewater treatment using inner loop three phase fluidized bed reactor is introduced. Performance of removal N and wiping off P is attained by controlling volumetric gas time and dissolve oxygen chrome. The best removal efficiencies of COD,TN and TP can reach 92% ,80% and 93% respectively,when the influent of COD,TN and TP reaches 352-1048 mg/L,46.9-76.4 mg/L,5.8-14.4 mg/L.The treated wastewater can reach two grade state standard. |
