针对亲水性或水溶性染料废水脱色降解难的问题，课题组应用高效菌生物强化、固定化技术处理印染废水。解决了单独高效菌接种处理废水时高效菌易流失、不易挂膜的难题，同时把高效菌和活性污泥接种各自的优点结合起来。该研究成果“Investigation of isolation and immobilization of a microbial consortium for decoloring of azo dye 4BS”和“Biodegradation mechanisms and kinetics of azo dye 4BS by a microbial consortium”在国外著名刊物《Water Research》, 《Chemosphere》上发表。
