摘　　要：[目的]对华润雪花啤酒(武汉)有限公司的污水污泥进行堆肥发酵处理工艺的研究。[方法]利用1 000 ml广口瓶模拟静态堆肥,采用啤酒废水处理剩余污泥为试材,通过正交试验,探讨影响堆肥效果的工艺参数(C/N、含水率、菌液添加量)的变化规律,确定静态堆肥的最佳工艺参数。[结果]堆肥工艺中影响腐殖酸生成率因素的大小顺序是:C/N比>菌液添加量>含水率。堆肥工艺的最佳工艺条件是:C/N比为30∶1、菌液添加量为0.25%、含水率为60%。[结论]该研究可为啤酒厂的污水污泥的堆肥发酵的工业化生产提供理论指导。[Objective] The aim was to study the composting technology of sludge from China Resources Breweries Co.,Ltd（Wuhan）.[Method] The research was carried out by static composting in 1000 ml wide-necked bottle by orthogonal test.The variation law of the composting technical parameters（C/N ratio,water content ratio and addition of bacterial liquid） was investigated for determining the optimum technical parameters of static composting.[Result] The factors influencing the yield ratio of humic acid followed the order： C/N ratioaddition of bacterial liquidwater content ratio.The optimum composting conditions were 30∶ 1 for C/N ratio,0.25 for addition of bacterial liquid,and 60% for water content ratio.[Conclusion] The research provided theoretical guidance for the industrial production of sewage sludge compost from brewery.
