摘要
将所筛选的高效脱色菌群，采用聚集－交联法固定在活性污泥上，形成絮状立体网状微观结构。固定化脱色菌－活性污泥的脱色酶活力较未经固定的活性污泥提高７０％左右。经厌氧条件下处理针织厂印染废水，色度平均去除率为７７．３％，ＣＯＤＣｒ平均去除率为６５．１％．
The highly efficient decolourization bacteria wereselected and immobilized on an activated sludgeby using an aggregated/cross-linked immob ilisation method to form a microstructure of crosslinked floccule-granule. The activity of decolourization enzyme increased by about 70% as compared with a non immobilized activited sludge.The results of textile dyeing wastewater treatment under anaerobic condition show that therewas an average colour removal 77. 3% with anaverage CODCr, removal of 65. 1 %.
