Abstract:

This paper discussed animal manure management strategies and technologies in Europe. The strategies were determined mainly by the development of local animal husbandry and environmental and economic factors. Two situations were discussed: one was that the manure generated by local breeding farms could be applied locally when the scale of animal husbandry was moderate; the other was that the manure produced by local breeding farms exceeded local land carrying capacity. Under the second situation, how to deal with the exceeded manure and remove the nutrients should be considered. Main manure treatment technologies applied in Europe included acidification, solid-liquid separation, composting, anaerobic digestion, aerobic biological treatment, concentration by vacuum evaporation, thermal drying, ammonia stripping and absorption, filtration and reverse osmosis, plant purification, etc.

Key words: animal husbandry, animal manure, land spreading, animal manure treatment technology, animal manure management strategy
