介绍了微生物电解池与厌氧膜生物（MEC-An MBR）反应器处理废水的作用机理.在尽量利用原有水处理设施前提下,以衡阳市某污水处理水厂的生活污水为处理对象,运用微生物电解池—厌氧膜生物（MEC-An MBR）反应器组合工艺对其进行中试试验,规模为1 m3/h.结果表明,该组合工艺能够明显提高生活污水的处理效率,减少膜污染,经处理后化学需氧量（COD）平均去除率可达88.8%,NH4+-N去除率为88.3%,TN去除率为72.1%,出水水质可达到《城镇污水污染物排放标准》一级标准,并能实现处理过程中稳定回收甲烷,减少能耗的目的.

The construction of the counterfort retaining wall is simple and economical,and widely used.However,under the complicated conditions of special topography and geomorphology,also by the influence of geology and surrounding environment,it is necessary to construct the composite retaining wall with pile anchor to meet the design requirements.Based on the actual situation of slope support design project of a certain district,a kind of pile-supported composite counterfort retaining wall is proposed,which use piles as carrying medium to improve the bearing capacity of foundation,anti-sliding and ant...
