摘要
畜禽粪污处理是我国可持续发展进程的重要难题,关系到我国养殖行业的发展和美丽乡村的建设。本文梳理了当下国内畜禽粪污资源化现状、发展趋势和相关政策法规,对好氧堆肥和沼气发酵等畜禽粪污资源化处理方式、应用现状等进行全方位综合对比并明确其优缺点和发展前景,结果发现,利用好氧堆肥技术处理畜禽粪污更符合我国国情。同时分析国内外在堆肥机理、发酵工艺和设备等研究进展,系统整理了堆肥发酵过程中关键因素对其效果的影响,包括含水率、碳氮比、温度、pH值、通气量和微生物菌剂等,最后分析了畜禽粪污资源化过程面临的难题并提出建议。
The impact of dispose of livestock and poultry manure is an important problem in the process of sustainable development in China,which is related to the development of livestock and poultry breeding and Beautiful Rural Construction.The resource utilization of livestock and poultry manure is the inevitable trend of waste treatment.According to the relevant policies and regulations on the resource utilization of livestock and poultry manure,we comprehensively compared the treatment processes,application status and development prospects of livestock and poultry manure resources such as aerobic composting and biogas fermentation to furtherly point out its advantages and disadvantages clearly in this paper.Then we found that the aerobic composting technology to treat livestock and poultry manure is more in line with the current Chinese conditions.Referred to the research progress of composting technology at home and abroad in terms of mechanism,technology and equipment,we summarized the influence of key factors in the process of aerobic composting in the treatment of livestock and poultry manure,including moisture content,carbon-nitrogen ratio,temperature,pH,oxygen concentration and microbial agents.Finally,we analyzed the current technical problems in the resource utilization of livestock and poultry manure and put forward relevant suggestions.
