集约养殖粪污能源工程的经济性分析

The Economical Efficiency of Excrement Energy Engineering in Breeding Industry

摘要: 畜牧业集约化发展，随之带来的污染问题越来越严重，对农业生态和食品安全造成威胁，也成为妨碍禽畜养殖产业健康发展的重要因素。本文运用成本效益模型分析德清源沼气发电工程的经济可行性，得出集约养殖企业可以通过沼气发电能源工程串起粪污综合利用的循环农业产业链，实现畜牧业污染物从“治”到“化”的转变。同时，在分析中得出养殖业沼气发电存在的经济效益未凸显、电量收购、补贴及产业链断裂等问题，针对问题对集约养殖沼气发电提出几点建议。

Abstract: With the development of stockbreeding, a lot of problems have been brought. The pollution is more and more serious, which has become a threat to the agricultural ecology and food safety. The pollution seriously affected the healthy development of the breeding industry simultaneously. In this paper, through the empirical analysis of Deqingyuan biogas power electricity generation en-gineering, it resulted that the breeding industry could make up a circulation agriculture industry chain by the project of biogas power electricity generation and change the situation of the livestock pollution from “cure” to “utilization”. At the same time, through the analysis, there are several problems, such as the economic benefits not reflected, the acquisition of power, subsidies and industrial-strand breaks. At last, there will be some suggestions to the biogas power electricity generation in breeding industry.
