METHOD AND DEVICES FOR BIOLOGICAL PURIFICATION OF WASTE

摘要

Process and apparatus for biological purification of organic wastes with earthworm compost including composting of solid materials on top of a water permeable layer and inoculation of an earthworm population in the compost material, comprising a sloping surface for removal of leakage water, spaced underneath the layer. In one embodiment of the apparatus according to the invention, the compost material is accommodated in an inner enclosure (7), surrounded and spaced from an outer enclosure (11) through which water from bath, laundery and dishes (BDL-water) is lead for heating of the compost material by engaging the bottom of the inner enclosure, and for humidification of the compost through drawing, by means of capillary action (17), BDL-water from a space (13) between the enclosures and into the inner enclosure.
