Exploration on Technology of Waste Treatment and Comprehensive Utilization on Liveslock Farm

In this paper, the technological characteristics of livestock excrement treatment systems employed in three projects developed by them are analyzed. They put forward a comprehensive technology system about livestock excrement treatment and the complex fertilizer producing technology by residue and effluent from the anaerobic digester. Compared with the technologies of solid-liquid separation, anaerobic digestion and aeration, it is necessary to combine excrement treatment with sustainable agricultural development and agricultural ecological circulation as to form a comprehensive systematical engineering of excrement treatment and utilization, and to reach a high unity of economic, social and ecological benefits.
