砚山县养殖场联户沼气工程现状及发展建议
|
摘要
砚山县是云南省重要的养殖大县,畜禽养殖业发达,但畜禽粪污问题也日益严重。沼气工程是处理畜禽粪污污染的重要手段。为了解砚山县养殖场沼气工程运行情况,对砚山县养殖场21处联户沼气工程进行调研。发现砚山县养殖场联户沼气工程存在不能满负荷运行、业主管理维护技能弱、沼肥经济效益差等问题,提出沼气建后服务体系、开展沼气综合利用和管理维护方面的培训、推动沼肥市场化的建议,提升沼气工程盈利能力,为砚山县养殖场沼气工程发展提供参考。
Yanshan County is an important breeding county in Yunnan Province. The livestock and poultry breeding industry is developed and the problem of livestock and poultry manure is also becoming more and more serious. Biogas project is an important means to deal with livestock and poultry manure pollution. In order to understand the operation of the biogas project in the farms, a survey was conducted in 21 biogas projects of the breeding farms in Yanshan County. The investigation found that the biogas project of the breeding farms had problems such as incapable of full-load operation, weak management and maintenance skills of the owner, and poor economic benefits of the biogas. Therefore, the biogas post-construction service system, the comprehensive utilization of biogas, and the management and maintenance of the biogas were proposed to promote the marketization of biogas fertilizers, improve the profitability of biogas projects.It can provide reference for the progress of biogas projects in the breeding farms of Yanshan County.
