摘要
中试研究表明 ,大型源水生物处理工程采用生物接触氧化技术除污染是完全可行的 ,主要污染物的去除效率高 ,而且启动迅速、填料容易挂膜 .生物膜成熟时每克填料上的细菌数量达 10 6～ 10 7个 ,膜上的动物种类繁多 ,数量大 .影响生物处理池稳定运行的主要因素有泥沙在填料上的过度积累和某些后生动物的大量生长 .通过试验提出了工程控制的措施 .
According to pilot-scale experiment result and practical run,it is feasible to imperial bio-treatment project with biological contact oxidation technique (BCOT) treating polluted raw water,its start-up period is quick and biofilm formation is easy,and the major pollutants can be removed efficiently.In mature biofilm,the amount of bacteria get to 10 6～10 7 per gram packings;the variety and quantities of protozoan and metazoan is plentiful.Several factors influencing bio-treatment project run result were studied and their controlling methods were suggested in the article.
