摘　　要：玉米淀粉工业废水是高浓度有机废水.利用其培养白地霉不仅可以净化玉米淀粉废水,还可以收获有用的菌体蛋白.研究表明当白地霉净化和资源化玉米淀粉废水的最佳条件为:不经灭菌处理的废水中添加0.1%KH2PO4、24 h振荡培养白地霉时,玉米淀粉废水的COD去除率为90%以上,每吨玉米淀粉废水可收获干燥SCP 1.6 kg以上,净化后废水的pH值为7左右.The wastewater of maize starch processing is an organic wastewater with high concentration. Culturing Geotrichum candidum from it, can not only purify the wastewater, but also get protein of organism. In this study, the best condition of purifying and being resources the wastewater is： putting 0.1% KH2PO4 into the unsterilization wastewater and culturing Geotrichum candidum by shaking table 24 h. Under the experimental condition, the rate of removal COD is more than 90%, dry SCP got from wastewater of maize starch is more than 1.5 kg per ton and the pH of purified wastewater is about 7.
