Definitions

  • the invention relates to a method for processing manure and to a device for performing this method.
  • the invention therefore has for its object to pro ⁇ vide a manure processing system which overcomes the above drawbacks.
  • a manure processing method which is characterized by collec ⁇ ting the manure, separating it into at least one solid and one liquid fraction and making both fractions suitable for use as fertilizer or nutrient.
  • the manure can thus be pro ⁇ Ded in simple manner and at small cost on or in the immediate vicinity of the cattle farm where it is produced.
  • Preferably applied variants of the method accor ⁇ ding to the invention form the subject-matter of the sub dependent claims 2-6.
  • a device for performing the above stated method is provided according to the inven ⁇ tion with means for collecting manure, first separating means placed in series with the collecting means for separa ⁇ ting the manure into at least one solid and one liquid fraction and posttreatment means placed in series with the first separating means for making the separated manure fractions suitable for further use.
  • Such a device can be constructed rapidly and at relatively low cost from simple commercially available components.
  • fig. 1 is a block diagram showing the different steps of the processing method according to the invention
  • fig. 2 is a partly sectional schematic view sho ⁇ wing a layout of the different parts of the processing device in their mutual relation

  • this cleaning station which is further supplied with air A, the liquid fraction is cleaned by bacteriological means.
  • the air herein released is re-routed back into the cleaning process.
  • the cleaned liquid fraction CL is subsequently separated in second separating means 6 into water W and residual materials R.
  • the latter may therein comprise for instance ammonia concentrate.
  • the clean water can be stored in a storage tank 7, for instance a silo, or can be used again directly as irrigation liquid I.
  • the collecting means 1 (fig. 3) comprise in the embodiment shown a gutter 8 which is recessed into the floor 15 in a cattle shed and which is covered by a grid 9.
  • the animals 10 stand with their rear end directed toward gutter 8 so that their excreta forming the M manure all directly therein.
  • a flushing liquid under high pressure is sprayed from a number of nozzles 11 into the gutter 8, whereby the manure is flushed to a collection tank 12. Flushing of the gutter 8 can also take place periodically under the control of a control system, for instance flushing cycles of 2 minutes each with an interval of 10 minutes. It is of course also possible for the farmer to sprayer the gutter 8 empty with a portable high pressure spray when he notes that it is full.
  • the clean water from the storage tank 7 can optionally be used as flushing liquid.

  • the cleaned liquid fraction CL collected in con ⁇ duit 42 is finally separated into water W and residual materials R in the second separating means 6, which can be formed by an ultracentrifuge or a second stripper.

Abstract

Procédé de traitement du lisier, consistant à recueillir le lisier, à le séparer en au moins une fraction solide et au moins une fraction liquide, et à rendre les deux fractions utilisables comme engrais ou comme matière nutritive. On peut rendre la fraction liquide plus largement utilisable par lavage bactériologique et par une nouvelle séparation. On a également prévu un appareil de mise en ÷uvre de ce procédé, comportant un dispositif de collecte du lisier, un premier dispositif de séparation monté en série avec le dispositif de collecte du lisier, et un dispositif de post-traitement monté en série avec le premier dispositif de séparation. Ce procédé et cet appareil permettent un traitement économique du lisier au niveau de l'exploitation agricole où il est produit, ou à proximité de celle-ci.
