摘要
试验分别利用三种生物处理方法：好氧、厌氧及酵母菌处理方法对稠油废水进行了处理。COD去除率在30%以下。在处理过程中，好氧污泥生物量表现出明显的增长。厌氧污泥及酵母菌在处理前后生物量几乎无变化。处理效果不明显与稠油废水可生化性差的性质有关，也与试验条件及选择菌种有关。
Three biological treatment methods have been investigated, including aerobic treatment, anaerobic treatment and yeasts treatment. The removal rate of COD is below 30%. The biomass of aerobic sludge obviously increased during the process of treatment. But those of anaerobic sludge and yeasts almost keep unchanged before or after the treatment. The unsatisfactory result related to the inferior biochemical property of viscous crude wastewater, as well as the test conditions and type of microbe selected during the test.
