区域畜禽废弃物全量化处理利用的模式探索

Mode Exploration for Total Disposal and Utilization of All Regional Livestock Wastes

随着我国畜牧业的快速发展和规模化养殖的不断提升,种养衔接失衡脱节的问题日益严峻,"养猪不种地、种地不养猪"的现象在客观上容易产生畜禽粪污无处"还"的现象,给生态环境和社会环境带来了十分严重的影响。为解决畜禽废弃物面临的污染问题,文章提出了"区域畜禽废弃物全量化利用"的理念。基本设计思路是估算粪污产生量和可收集量、分析利用现状、确定有机肥量、规划产业发展布局、健全保障体系。在此基础上归纳总结了"有机肥料还田型、多元循环利用型、产业利用主导型"等畜禽废弃物全量化利用模式的特点并分析典型案例的使用效果,为实现区域畜禽废弃物全量化处理利用提供理念引导和技术支撑,推动畜禽废弃物实现其应有的资源价值。

With the rapid development of animal husbandry and the continuous improvement of large-scale farms in China,the unbalance and disconnection between planting and breeding is increasingly serious. The phenomenon of breeding without planting and planting without breeding leads to nowhere to use of livestock waste,and it has brought serious impacts on the ecological environment and social environment. In order to solve the pollution caused by livestock waste,this paper puts forward the idea of total utilization of regional waste. The basic design idea is to estimate the output of waste and the amount possible collected,analyze the current situation of utilization,ascertain the amount of organic fertilizer,plan the layout of biogas industrial development,and improve the guarantee system. On this basis,the paper summarized the characteristics of different kind of total utilization models for livestock and poultry wastes,including organic fertilizer returning to the field,multiple recycling,and industry-led utilization. And the application effect of typical cases were analyzed.
