Experimental Research on the Degradation of Organic Compounds in the Coking-Plant Wastewater by Superiority Bacteria

  • 摘要: 从焦化厂曝气池活性污泥和废水处理工艺出水中筛选出6株革兰氏阳性优势菌,根据菌株、菌落形态和大量生化实验将菌株鉴定到属.确定了降解所需的最佳实验条件.分别为温度30 ℃,转速100 r/min,菌株投加量20%(V(菌液)/V(废水)).实验发现,筛选出的6株优势菌对喹啉、吡啶和萘有良好的降解效果,但以喹啉为碳源和氮源筛选出来的H24,H26和H31对喹啉的去除率优于其他3株菌株,而以萘为唯一碳源的H14对萘的去除率优于其他菌种.6株优势菌的驯化活性污泥能进一步提高对喹啉、吡啶和萘的去除能力,去除率在90%以上.
