摘　　要：采用臭氧／过滤／活性炭工艺深度处理济南市水质净化二厂的二级出水。结果表明，在臭氧投加量为3mg／L、滤床和炭床的滤速均为6～12m／h、各工艺段的接触时间为13min的条件下，组合工艺对浊度、CODMn、NH4＋-N和NO2^-—N均有一定的去除效果，而对NO3^--N基本无去除作用；当原水的平均浊度、CODMn、NH4^＋-N和NO2--N分别为0．87NTU、1．24mg／L、1．78mg／L、0．13mg／L时，组合工艺出水的平均浊度、CODMn、NH4^＋-N和NO2^--N分别可降至0．25NTU、0．79mg／L、1．29mg／L、0．05mg／L。The ozone/filtration/activated carbon process was used to treat the secondary effluent from the Jinan Second Wastewater Purification Plant. The results show that when the ozone dosage is 3 mg/L, the filtration rates of the filter bed and carbon bed both are 6 to 12 m/h, and the contact time is 13 min, the combined process has certain removal efficiency of turbidity, CODMn, NH4 - N and NO2 - N, but no removal efficiency of NO3^- - N. When the average turbidity, CODMn, NH4 - N and NO2 - N in the raw wastewater are 0.87 NTU, 1. 24 mg/L, 1.78 mg/L and 0.13 mg/L respectively, the average turbidity, CODMn, NH4 - N and NO2 - N in the effluent of the combined process are decreased to 0.25 NTU, 0.79 mg/L, 1.29 mg/L and 0.05 mg/L respectively.
