摘　　要：玉米淀粉工业废水中含有多种有机和无机物质,可作为微生物生长繁殖所需要的优良营养物质.其中自然生长着多种细菌和酵母菌,这些微生物在以玉米淀粉废水为营养的生长繁殖过程中净化了淀粉废水.废水中的微生物与白地霉共同作用可比单独使用白地霉净化废水时的COD去除率提高28.83%,净化后的废水pH值平均为7.08.The wastewater from maize starch processing contains varied organic and inorganic materials. It can be the fine nutrient for many microorganism to grow and breed. In the wastewater many bacteria and yeasts grow naturally. In the course, the wastewater is purified. When using Geotrichum candidum and the microorganism of the wastewater to purify the wastewater together, the rate of removal COD can be raised 28.83 % than only Geotrichum candidum. After purifying , the pH of the wastewater averages 7.08.
