摘　　要：为北方城市污水处理的CAST工艺在冬季进水温度低和有机负荷低的条件下进行启动调试及活性污泥培养驯化提供经验,促进该工艺在寒冷地区的推广应用.研究结果表明,在冬季进水温度低和有机负荷低的条件下,采用接种法培养驯化活性污泥20天就能完成污泥培养驯化,满足污水处理要求,出水达到设计标准.北方城市污水处理的CAST工艺在冬季低水温、低有机负荷低的条件下应采用接种法培养活性污泥。The purpose of the article is to supply experience of the activated sludge culturing and domesticating and start running for wastewater treatment plant with CAST type of SBR process at the low inlet temperature and the low nutrition in winter of north- ern area, and promotes the application of this craft. The results show that the sludge culturing and domesticating is completed by twenty days using inoculation method in winter, and the outlet quality meets the design standard. Hence, it is an effective way for the plants in northern cities to adopt inoculation to culture activated sludge at the low inlet temperature and the low nutrition in winter.
