摘要
针对日益严重的水体富营养化问题,结合中国南方中小城市污水处理现状,阐述了循环活性污泥法(CAST)的工作原理,并利用它处理城市生活污水.试验表明,其排放废水的各项污染指标均达到国家《污水综合排放标准》(GB8978-1996)一级标准,在城市生活污水处理中,尤其是含氮、磷较高的,有良好的研究开发价值和广阔的推广应用前景.
In view of more and more serious eutrophication of water bodies and combination of municipal wastewaters of treatment in south china, the principle of Cyclic Activated Sludge Technology （CAST） was introduced in this paper. Experimental results indicate that the discharged water meets the National Integrated wastewater Discharge Standards（GB8978--1996） of the first standards. The application prospects of CAST should be widely popularized and given energetic study and development to the municipal wastewaters, especially to the treatment of nitrogen and phosphorus containing highly.
