摘　　要： 应用经复合微生物技术处理的制糖和酒精发酵混合废水进行灌溉实验,探讨实现工业废水无害化及资源化的可行性。为期2a的实验结果表明,灌溉废水对土壤的肥力没有不良的影响,不会造成土壤肥力的下降或土壤酸化,也不存在增加土壤重金属质量分数的危险。 The sugar-refinery and alcohol making wastewater were treated by compound microorganisms technique, and the changes of soil properties of sugarcane farm after being irrigated with the wastewateer were investigated in Liuzhou, Guangxi, in 1999 and 2000. As the treatments, the wastewater with different concentration were irrigated into the plots of newly grown sugarcane (Saccharum officinarum L.), and without irrigation and irrigating clear water were conducted as controls (CK1 and CK2). The results showed that the wastewater irrigation did not decrease the soil fertility, and did not cause soil acidifying or heavy metal contamination.
