PROCESS FOR RECOVERING SEWAGE-SLUDGES CONTAINING COMMUNAL AND/OR HARMFUL MATERIALS-WITH EISENIA FOETIDA

摘要

The present invention relates to a method for extracting sewage sludge containing communal and / or harmful substances. The process is characterized by the fact that 50-60, preferably 50 cm thick, 185-200, preferably 190 cm, arbitrary lengths of concrete having a thickness of 1400-1600, preferably 1550 pieces, are formed on a concrete foundation found 50 cm above the ground level of the sewage sludge. fertilizer (Eisenia foetida) as a propagating material and a carrier material of 1.15 to 1.3, preferably 1.2 kg; the bedding thus formed is left to stand for six months, and the worms are removed from the remaining nutrient-rich compost. The fertilizer material is planted with 38-42, preferably 42% of adult breeders, with the same amount of adult agglomerates, and finally 18-22, preferably 20% of the cocconium. The carrier material is a cultivation product of the manure agglomerated with bacteria remaining at the end of the digestion process. EN 199098 B t Description: 3 pages without drawing -1-
