规模化养猪场粪污治理模式构建探讨
|
摘要
针对规模化养猪场,根据可持续发展的理念,以实现粪污达标排放为目标,辅以资源化利用最大化为原则,笔者通过工艺技术集成创新,提出了"固液分离-厌氧发酵-好氧曝气-达标排放"粪污治理工艺,结合沼气、沼液温室大棚应用以及粪渣、沼渣厌氧干发酵堆肥等资源化利用,形成规模化猪场粪污治理模式。实践结果表明:该模式能够实现粪污治理达标排放,避免粪污排放造成环境污染,同时实现有效资源再利用,有望为规模化猪场建立一种实用污水达标排放生态型技术模式。
According to sustainable development,based on the goal of reaching drainage standard and the principle of maximizing the utilization of resources,through technology integration and innovation,a comprehensive pig waste disposal model,in cluding solid-liquid separation,anaerobic fermentation,aerobic aeration,standard discharge combining with the utilization of biogas and application of biogas slurry in greenhouse,as well as the resource utilization of biogas residue,was put forward in this paper,so as to form a pig manure disposal model for large-scale pig farms. The model was applied to Youkang Pig Breeding Co.,Ltd. of Fujian Province,and the results showed that the model could achieve standard discharge of sewage treatment,so avoided environmental pollution caused by sewage discharge and realized effective resource reuse.
