  摘要:

  以赣南地域低碳源现实城市污水为研究对象，阐发了UNITANK工艺中边池厌氧时候对系统脱氮除磷机能的影响。成果注解，当内回流比为100%时，跟着边池厌氧时候的增添，TN去除率显现先增添后减小的趋向，而TP去除率则逐步增年夜；边池厌氧时候对COD、NH3-N的去除结果影响较小。当厌氧时候为60 min时，出水COD、NH3-N、TN、TP的平均浓度别离为11.07、0.93、11.78、0.85 mg/L，除TP外其他3项目标均优在《城镇污水处置厂污染物排放尺度》（GB 18918—2002）的一级A尺度要求；经由过程考查实验装配边池半周期内各组分浓度的动态转变，在边池厌氧时候为100 min的前提下，厌氧释磷现象最为较着，边池NO-2-N堆集浓度最高，边池具有反硝化进程和释磷进程对碳源的合作问题。

  Abstract:

  The effect of the anaerobic time in the side tank on the efficiency of nitrogen and phosphorus removal of the UNITANK process was investigated ba���λ�appsed on the actual municipal sewage from the south Jiangxi area. The results showed that when the internal reflux ratio was 100%, with the increase of the anaerobic time in the side tank, the removal rate of TN was firstly increased and then decreased, while the removal rate of TP increased gradually. The anaerobic time in the side tank had negligible effect on the removal efficiency of COD and NH3-N. When the anaerobic time was 60 min, the average concentrations of effluent COD, NH3-N, TN and TP were 11.07 mg/L, 0.93 mg/L, 11.78 mg/L and 0.85 mg/L, respectively. All indicators except TP had satisfied the first level A standard in the Discharge Standards of Pollutants for Municipal Wastewater Treatment Plant (GB 18918-2002). The dynamic changes of the component concentrations in the half cycle of the side tank were investigated. When the anaerobic time in the side tank was 100 min, the anaerobic phosphorus release was obvious, and the concentration of NO-2-N in the side tank was at the highest level. The processes of denitrification and phosphorus release in the side tank competed for the carbon source.
