不同季节及厌氧发酵对奶牛场污水及沼液各污染指标的影响

摘要

随着奶牛养殖业的迅猛发展，奶牛场排放的废弃物越来越集中，产生的环境问题也日益受到人们的关注。其中奶牛场排出的废水严重污染着水体和土壤，因此对其进行排污分析尤为重要。本试验对规模化奶牛场产生污水的主要污染指标及沼液的特性进行了测定分析，以期为规模化奶牛场污水的处理和利用提供依据。%With the rapid development of the dairy industry, pollutants discharged by the dairy farm become increasingly serious, and the consequent environmental problems receive more and more attention from society. Among all the pollutants, wastewater discharged by the dairy farm heavily damages the water body and the earth. Therefore, it is of particular importance to analyze the wastewater discharge. This research tested and analyzed the major pollution indicators and the features of liquid biogas of the wastewater discharged by large-scale dairy farms, so as to provide reference fieures to the treatment .ncl ,,,;1;~.~-;^- ^c
