An Exploration on the Technology of Waste Treatment and Comprehensive Utilization in Stock Farm

摘要

In this paper the author analyzed the technological characteristics of livestock excrement treatment employed in three projects undertaken by them. They put forward a comprehensive technology system about livestock excrement treatment and the complex fertilizer producing technology by residue and rest liquid from methane generating pit. Comparing the technology of solid-liquid separation, anaerobic fermentation and aerobic aeration, in China it is necessary combine excrement treatment with agriculture sustaining development and agricultural ecological benign circulation, form a comprehensive systemic engineering of excrement treatment and utilization, reach a high unity of economic, social and ecological benefits.
