印染废水的排放量逐年增加，对水环境污染威胁日益加剧。微生物絮凝剂作为当前一种具有发展潜力的新型环保型絮凝剂，在印染废水的处理方面具有广泛的应用前景。本实验从校外濂溪河的污泥中分离出28种微生物，然后对印染废水进行处理，筛选出了3种处理效果比较好的微生物X4、X5、X6，接着对X4、X5、X6进行优化实验。结果表明：X4、X5、X6的最佳碳源分别是蔗糖、葡萄糖、蔗糖；最佳氮源分别是硫酸胺、蛋白胨、硫酸胺；最佳无机盐都是KCl；最佳培养温度分别是37℃、34℃、370C；最佳培养pH分别是7、自然、自然；最佳培养天数都是5d。在最佳培养条件下，X4、X5、X6能达到的脱色率分别是52．2％、51．4％、57．1％。

As printing and dyeing wastewater discharge is increasing year by year, threat to water environment is being intensified. As a kind of potential new environmental flocculant, microbial flocculants has a widespread prospect in treatment of printing and dyeing wastewater. In this experi- ment, printing and dyeing wastewater treatment was conducted by using 28 kinds of microorganisms extracted from the Lianxi River near Jiujiang University and three microorganisms X4, X5, X6 which have better effect were screened out and optimized. The result shows： the best carbon sources of X4, X5, X6are respectively sucrose, glucose and sucrose. The optimum nitrogen sources are Ammonium Sulfate, Peptone and Ammonium Sulfate. the best inorganic salts are the same as called KC1. Most proper incubation temperatures are respectively 37℃, 34℃, 37℃. The best incubation pH is 7, nat- ural and natural. The best incubation period are all 5 days. Under the optimal condition, the decolori- zation rate of X4, X5, X6 can separately reach 52. 2 %, 51.4% and 57. 1%.
