Low emission waste free treatment of agricultural by prods. - by continuous prodn. including solids sepn. filtration and reverse osmosis, with recycling of water

摘要

Low-emission waste-free treatment of agricultural by-prods. by using known arrangements for solids sepn. for filtration and for reverse osmosis. After normal sepn. of solids, the thin liq. manure is subjected to partial enzymatic-microbiological prepn. to increase and accelerate the biogas prodn. in an "activator" contg. acid- and growth-material produced in UF (ultra filtration) impulse reactor. USE/ADVANTAGE - An ecologically, ecnomically and technologically effective method is offered for the continuous treatment of agricultural by-prods. such as liquid manure from cattle, pigs, and poultry, with prodn. of biogas, compost and other bio-manures together with complete recycling of the water which is fit for drinking by animals or for re-use in the treatment.
