试验结果表明，好氧/厌氧交替活性污泥法(AAA-CMAS)系统在满负荷和低负荷条件下都能产生高质量的出水。AAA-CMAS系统的曝气节能和污泥减量分别达到30%和15%量级。由于反硝化过程是在可控条件下在反应器内进行的，而不是在反硝化度无法控制的沉淀池中进行的，因此AAA-CMAS系统的出水中含有的悬浮物和大肠杆菌数量比传统系统少得多，从而进一步节省了滤池的氯化和反冲洗成本。
Results of our trials demonstrate that the alternating aerobic/anaerobic activated sludge (AAA-CMAS) system is capable of producing effluent of high quality in either fully-loaded or under-loaded conditions. The aeration energy saving and the sludge reduction of the AAA-CMAS system was shown to be of the order of 30% and 15% respectively. Because denitrification process is taking place within the reactor under controlled conditions and not in the sedimentation tank where degree of denitrification cannot be controlled, effluent of the AAA-CMAS system was found to contain much less suspended solids and E. coli counts than that of the conventional system, resulting in further cost saving in chlorination and in back-washing of the filter.
