Analysis on Large-scale Pig Farm and the Development of Biogas Engineering-Taking Qionglai City as an Example

摘要

As an effective method of disposal for animal manure, Scientific and economical biogas engineering plays an important role in accelerating construction of eco-agriculture, and also protecting eco-agriculture environment. Meanwhile, there are some problems related to technic and policy with large-scale biogas engineering, which seriously influence its development. So, this paper took Qionglai city as an example, summed up the present status, existent problems of intensive culture and biogas engineering, which based on analyzing the inherent relations between the scale of pig farming and disposal capacity of biogas engineering. It also expected the developing potential of large-scale biogas engineering.
