摘　　要：惠阳污水厂二期扩建,把原来的CAST工艺改为倒置A2/O工艺,用二氧化氯代替紫外消毒,排放标准不变,都是国家《城镇污水处理厂污染物排放标准》(GB18918-2002)的一级B标准。文章对该厂扩建前后的工艺设计、建筑投资、占地、运行效果、运行成本等进行了对比,得出CAST工艺比倒置A2/O工艺更节省土地、节省建筑成本和运行成本的结论。Huiyang wastewater plant phase ii expansion is that the inverted A2/O process is used instead of the original CAST process, and disinfection with chlorine dioxide instead of ultraviolet. The effluent from new process can meet the national ＂urban sewage treatment plant pollutant discharge standard＂ （GB18918-2002） standard of level 1 B. In the paper after the comparison with the expansion of the process design, construction investment, area, running effect, operation cost and so on, it is concluded that the CAST process is more than the inverted A2/O process in saving land, saving construction cost and operation cost.
