Method for processing semi-liquid manure and the device to be used

摘要

A method for processing semi-liquid manure wherein this semi-liquid manure is separated by sieving into a liquid and a solid fraction, the liquid fraction is subjected to a biochemical decomposition process and to a flotation/sedimentation step. The thus obtained aqueous phase is in particular subsequently subjected to an ultrafiltration step, an ion exchange step and to a reverse osmosis in order to produce purified water and a concentrate. The ion exchanger is cleaned by means of lime milk, which thus also produces a usable fertilizer. The invention also relates to a device for applying this method.
