啤酒厂污泥与棉籽饼袋式堆肥及效果

为快速高效无害化处理啤酒厂污泥，对啤酒厂的污水污泥进行微好氧堆肥发酵处理工艺进行了研究，重点研究了啤酒厂污水污泥袋式堆肥过程中温度、含水率、pH值、腐殖酸、有机碳、全氮、水溶性有机碳、发芽指数等参数的变化规律。结果表明：采用棉籽饼作为啤酒厂污水污泥的调理剂，将啤酒厂污水污泥与棉籽饼按照质量比4︰1的比例（添加质量分数为0.5%的尿素，调节C/N为30︰1，含水率为60%）进行混合后，每袋50 kg进行打包后封口发酵，21 d后出料松散且无臭味，堆肥产品腐熟，卫生学指标达到了国标要求。该研究为建立快速高效处理啤酒厂污泥新工艺提供了技术依据。

Rapid and high-efficient composting process by bag-type of brewery sludge and cottonseed cake

Based on the dynamic composting process of wastewater sludge from China Resources (Wuhan) Breweries Co., Ltd., the dynamics of different operational and evaluating indices, such as temperature, moisture content, pH, humic acid, total organic carbon, total nitrogen, water-soluble organic carbon and germination index (GI) and so on, during the treatment process were discussed. The results indicated that cottonseed cake used as compost amendment of brewery sludge. Brewery sludge and cottonseed cake mixed in accordance with the ratio of 4:1 (add a small amount of urea, adjust C/N ratio of 30:1, 60% moisture content). 50 kg was a unit which was packed into a bag for sealing and micro-aerobic composting fermentation. The product of composting was mature after 20 days, which was loose and odorless. Almost mature output could meet the land application control standard of MSS and the class A standard of US EPA. The study provides the technical basis for new process of establishing rapid and high-efficient processing Brewery sludge.
