| 摘 要： | 为了考察奶牛场粪污制备卧床垫料过程中的牛粪性质及相关污染物含量的周年变化规律,选择天津市一家规模化奶牛养殖场作为研究对象,进行不同阶段、不同季节的连续采样,并对样品中的TN、TP、pH、含水率、有机质、粪大肠菌群和Cu、Zn等重金属进行了系统检测分析。检测数据分析显示:泌乳牛牛粪中的TN、TP、VS、Cu、Zn的排放量存在显著性季节差异(P0.05),且TN、TP、Cu、Zn、Cd的排放量均以冬季最高;经过BRU(Bedding Recovery Unit)好氧发酵处理后,再生牛粪固体中的含水率、重金属Zn和粪大肠菌群的含量出现不同程度的降低,而TN、TP和重金属Cu的含量则基本呈现升高趋势。

| Abstract: | In order to investigate the annual variation of the properties of dairy manure and the contents of the related pollutants in the process of preparing recover bedding material with liquid manure, a typical large-scale dairy farm in Tianjin was selected as the research object in this study. Continuous sampling was conducted in different stages and different seasons. TN, TP, pH, water content, organic matter, fecal coliform, Cu, Zn and other heavy metals in the samples were detected and analyzed. The results showed that there was a significant seasonal difference(P<0.05) in TN, TP, VS, Cu and Zn emissions from dairy manure, and the emissions of TN, TP, Cu, Zn and Cd were the highest in winter. After BRU(Bedding Recovery Unit) aerobic fermentation, it was found that the moisture content, Zn -content and fecal coliform had various degrees of decrease, while TN, TP and Cu-content showed an increasing trend in the recycled manure solid. |
