摘　　要：利用潜水导流式氧化沟污水处理试验装置处理生活污水,研究了HRT,DO以及气水比对潜水导流式氧化沟污水处理工艺的影响。结果表明,HRT为14 h时,出水TN浓度最低,为8.57 mg/L,系统处理效果最好;氧化沟内DO浓度平均值为2.0mg/L时,出水TN浓度达到最低,DO浓度平均值高于2.0 mg/L时,出水NH4+-N浓度变化较小;气水比为7时,系统出水TN浓度最低,为8.84 mg/L,此时去除率为80.73%。Use of experimental apparatus of diving and diversion Oxidation Ditch for domestic wastewater treatment, the paper researches the influence of HRT, DO and gas-water ratio on diving and diversion Oxidation Ditch technology. The results show that the lowest effluent cofi＇centration of TN was 8.57 mg/L when the HRT was 14 hours, the treatment effect is best; the effluent concentration of TN was lowest when the DO means was 2.0 mg/L, the effluent concentration of NH4^＋-N had less change when the DO means was more than 2.0 mg/L in diving and diversion Oxidation Ditch; the lowest effluent concentration of TN was 8.84 mg/L when the gas-water ratio was 7, meanwhile, removal efficiency of TN was 80.73% in the system.
