规模畜禽养殖场的污染防治技术后评价方法研究

对我国畜禽养殖场规模进行初步划分,调查了目前畜禽养殖业普遍使用的处理技术,将后评价技术中层次分析和灰色关联度法相结合,评价出适用于不同规模畜禽养殖场的污染防治技术。结果表明,对于大型畜禽养殖场,最适宜的工程技术是能源型沼气工程,其次是发酵床;中型畜禽养殖场,最适宜的污染防治工程技术是发酵床,其次是能源型沼气工程;小型畜禽养殖场,首先推荐发酵床,其次是好氧堆肥技术。该后评价实现了定性评价与定量评价的结合,保证了评价结果的科学性和公正性,为畜禽养殖场选取适用技术提供了依据。

Study on Post-evaluation Methods of Pollution Control Technology for Livestock and Poultry Farms of Different Scales

Livestock and poultry farms in China were preliminarily divided into different scales.The popular pollution treatment projects were investigated.With the combined methods of Analytic Hierarchy Process and Grey Relational Analysis,pollution control technologies were evaluated to fit for livestock and poultry farms of different scales.The results show that energy type biogas project is the best pollution treatment project for large-sized livestock and poultry farms,and fermentation bed ranks secondly.Deep-litter bed is the best project for medium-sized livestock and poultry farms,and energy type biogas project ranks secondly.Deep-litter bed is the best project for small-sized livestock and poultry farms,and aerobic composting ranks secondly.The evaluation method combines qualitative and quantitative evaluation,ensures that the evaluation results are scientific and impartial,and provides the livestock and poultry farms with the suitable pollution treatment technologies.
