| 摘 要： | 设计一种自动增氧型垂直下行流生活污水处理器,采用间歇运行的启动方式,对比研究1号系统(完全空白系统)、2号系统(垂直下行流生活污水处理器系统)和3号系统(自动增氧型垂直下行流生活污水处理器系统)对SS、COD、TP、TN的去除效果。结果表明,经过45d的启动时间后,3号系统对SS、COD、TN、TP的4d去除率分别达到91.8%、82.4%、93.4%和91.6%,去除效果优于2号系统;3号系统在较短停留时间内就可以获得理想的去除效果。

| Abstract: | A self-aeration vertical upward-flow sewage processor was designed, starting with intermittent operation. Removal efficiency of SS, COD, TP and TN of the System No. 1 (a blank system), System No.2 (a system of vertical upward-flow sewage processor) and system No.3 (a System of self-aeration vertical upward-flow sanitary sewage processor) were studied. Results showed that as to System No.3, removal efficiency of SS, COD, TP and TN could separately reach 91.8%, 82.4%, 93.4% and 91.6% after 45d start-up period... |
