摘　　要：为进一步提高生物处理工艺脱氮除磷效果,采用连续曝气生物膜反应器对生活污水进行了实验研究,分析了污染物去除效果和主要影响因素。结果表明,在HRT=3 h的条件下,将DO的质量浓度控制在2 mg/L可取得较好的同步脱氮除磷效果,出水NH4+-N、TN、TP的质量浓度和COD分别为2.83、11.9、0.56 mg/L和24.7 mg/L。在HRT=3 h、ρ(DO)=(2±0.2) mg/L的条件下,提高进水碳氮比可进一步优化同步脱氮除磷效果,COD/ρ(TN)=8时,NH4+-N、TN、TP去除率分别为92%、77.6%、85.4%。In order to improve the nitrogen and phosphorus removal effects by biological treatment technology, the continuous aeration biofilm reactor was used to carry out an experiment for domestic sewage treatment. The pollutants removal effects and influencing factors were analyzed. The results indicated that, under the condition of HRT was 3 h and mass concentration of DO was 2 mg/L, the simultaneous nitrogen and phosphorus removal was efficient. The mass concentration of NH4+-N, TN, TP and COD in the effluent were 2.83, 11.9, 0.56 mg/L and 24.7 mg/L respectively. Under the condition of HRT was 3 h and ρ(DO) was(2±0.2) mg/L, the simultaneous nitrogen and phosphorus removal effects were improved by increasing the carbon nitrogen ratio. When COD/ρ(TN) was 8, the removal rates of NH4+-N, TN, TP were 92%, 77.6% and 85.4% respectively.
