摘要
对A2O工艺和倒置A2O工艺处理珠三角地区生活污水的效果进行对比研究。结果表明,2种工艺出水水质均能稳定达到排放限值要求,适合生活污水的深度处理。倒置A2O工艺的NH3-N去除率显著高于A2O工艺,但TP去除效率显著低于A2O工艺,TN去除效率不存在显著差异,但倒置A2O工艺出水TN质量浓度较A2O工艺稳定,在TN去除方面具有较强的抗冲击能力及稳定性。分析了影响2种工艺脱氮除磷效果的因素,并提出改进建议,为同类型污水处理厂工艺改进提供参考。
Treatment effects of municipal sewage by A2O and reversed A2O process were investigated.Results showed that effluent of both processes met the discharged standards,which could be chosen as advantaged wastewater treatment process.Treatment percentage of NH3-N in reversed A2O process was significantly higher than that in A2O process,but treatment percentage of TP,on the contrary.Treatment percentage of TN had no significant difference in both processes,but TN concentration of the effluent in reversed A2O process was much more stable than that in A2O process,which showed that TN treatment by reversed A2O process was of impact resistance and stability.Influence factors about efficiency of NH3-N,TN and TP removal were analyzed and suggestions were presented,providing reference to the improvement of wastewater treatment plants.
