摘　　要：应用好氧微生物白地霉和拟内孢霉净化玉米淀粉生产废水,并生产出有用的SCP.玉米淀粉废水中溶氧量的多少直接影响着玉米淀粉废水的资源化与净化效率.在相对充足氧气的试验条件下,废水COD去除率12h内即可达83.7%,同时每吨废水生产SCP1.652kg.The study applied the aerobes(Geotrichum candidum and Endomycopsis) to purify maize starch's wastewater and produce useful SCP. The quantity of dissoluble oxygen can affect the efficiency directly of the purification and being sources the wastewater of maize starch. Under the experiment conditions of relative ample oxygen, COD of the wastewater can be removed 83.7% within 12 hours. And at the same time, every ton of wastewater can produce 1.652kg SCP.
