| 摘 要： | 论述了三槽式氧化沟处理石化废水的试验研究，试验结果表明：在系统开始时水力停留时间过短不利于硝化，当运行稳定后．在10h左右的水力停留时间时，三槽式氧化沟出水NH3-N浓度为2．7mg/L，NO3^--N浓度为5．2mg/L，可以达到较好的硝化效果．并将小试研究结果与污水处理厂的实际运行作了比较．

| Abstract: | A bench scale tri-trough oxidation ditch was used to treat petrochemical wastewa ter. The results shown that: if the hydraulic retention time was too short in th e beginning stage, the nitrification effect was not good. After the system ran s table and the hydraulic retention time was changed to 10hr, the effluent NH2-N ammonia nitrogen concentration from tri-trough oxidation ditch was 2.7mg/L and NO-3N (nitrate-nitro-gen) concentration in effluent reached 5.2mg/L.The nitrification effect was good. The results of the bench-scale test were compared with those of the full-scale wastewater treatment plant. |
