规模养猪场粪污综合治理和利用技术研究

Study on the comprehensive treatment and utilization to livestock waste of large-scale pig farm

近年来,养猪业的规模化发展与伴随而来的环境污染矛盾日益加剧,如何综合处理规模养猪场的粪污,实现污染物资源化利用,成为当前一项十分重要而紧迫的科研任务。文章以防城港市5个具有代表性的规模猪场为例,在考虑容量化控制和科学合理布局粪污处理设施的基础上,通过对各猪场排泄粪污采用雨污分流、干湿分离、污水处理等技术综合治理,并对经处理粪污进行资源化利用效益分析,探讨规模化猪场粪污综合治理的有效技术措施。

With the contradictions between the scale development of pig industry and the accompanied environmental pollution increasingly in recent years, it has become an important and urgent scientific task that how to deal with the livestock waste of large-scale pig farms to realize the pollutant resource utilization. This study uses five representative large-scale pig farms as examples in Fangchenggang City. Considered on the basis of capacity control and scientific rational distribution of waste treatment facilities, the comprehensive treatment technology of rainwater and sewage separation, dry-wet separation and sewage treatment were used to analyze the resource utilization efficiency of manure treatment, and discuss the effective technical measures of manure comprehensive treatment in large-scale pig farms.
