CAST工艺在寒冷地区城市污水处理厂中的应用

摘要

A CAST process was used to treat municipal wastewater in cold regions. The Suihua wastewater treatment plant is presented to show the parameter design and equipment selection from the design view. In addition, the pollutant removal efficiency is analyzed in cold winter. The results show that, as a favorable performance wastewater treatment process, the CAST process can be used in extremely cold regions totally. System effluent can satisfied the national standard class II for the municipal wastewater treatment steadily.%采用CAST工艺处理寒冷地区城市污水,以绥化市城市污水处理工程为背景,详细介绍了CAST工艺设计参数、设备选型等设计问题,并介绍了CAST工艺在冬季运行期间对污染物的去除性能.结果表明,作为一种高效的污水生物处理工艺,CAST完全可以用于高寒地区城市污水的处理,并可以稳定满足国家《城镇污水处理厂污染物排放标准》(GB18919-2002)一级B排放标准.
