| 摘 要： | 采用淹没式膜法水解-交替脉冲曝气系统对城市污水的处理效能进行研究,讨论了装置进水COD浓度变化对生活污水处理效果的影响、处理工艺沿程COD、NH3-N浓度变化状况、NH3-N的去除、水解对COD去除效果的影响以及进水COD/N比与反硝化的关系。研究表明,该系统能有效地去除COD和NH3-N。进水COD在450mg/L以下时,出水COD基本维持在60mg/L以下;进水NH3-N<50mg/L时,出水NH3-N<10mg/L。

| Abstract: | The treatment efficiency of municipal wastewater was studied by hydrolytic-alternate pulse aeration process of submerged membrane method. Some influence factors were discussed, including influent COD concentration, concentration distribution of COD and NH3-N along the treatment process, removal of NH3-N, influence of hydrolysis on the removal of COD as well as relations between COD/N ratio and denitrogenation. Results showed that the treatment process was efficient to remove COD and NH3-N in the municipal wastewater. When the influent COD was not below 450mg·L-1, the effluent CODr kept no more than 60mg·L-1. The effluent NH3-N was below 10mg·L-1 when the influent NH3-N was less than 50mg·L-1. |
