摘要
寒冷地区冬季漫长，水温过低，致使活性污泥中的微生物代谢能力下降，有机物去除效果差。这是长久以来难以解决的问题。为了提高寒冷地区冬季污水处理效果，筛选、驯化高活性、耐低温的微生物势在必行。本文分离、鉴定了 4种酵母菌，它们均能在 2℃时生长，并能有效地降解有机物。同时还测定了 4℃下单菌对 CODCr的去除率，其中 Y01菌株对 CODCr的去除率达到 82％。 4种酵母菌经大量培养和驯化，有应用于污水处理的可能性。
In cold area the metabolized ability of activated sludge is low because of the low wastewater temperature in the long winter. So it is difficult to improve the effects of bio－ treatment in winter of cold area. To isolate and domesticate active sludge that is high efficiency and low－ temperature－ resistant is a novel way to solve the problem. In this paper, four kinds of yeast which can accrue and degrade organic pollution in 2℃ were isolated and identified. At the same time, the removal rate of CODCr of single yeast in 4℃ was measured. The removal rate of CODCr of yeast Y01 was 82％ , which showed it is possible to apply them to sewage treatment.
