奶牛场粪污制备卧床垫料过程中物料性质及污染物含量的周年变化规律
Annual variation of material properties and pollutant content in the process of dairy manure making bedding in dairy farm
摘要
Abstract
In order to investigate the annual variation of the properties of dairy manure and the contents of the related pollutants in the pro-cess 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.关键词
