Resumo:
This vvork had, as objective the disinfection of the anaerobic mud originating frora of
Anaerobic Digestores of Ascending Flow (DAFA), installed in PROSAB / Campina
Grande-Pb, through the vermicompostagem with red earthworms of Califórnia. The
experiment was accomplished during the period of June to October of 2002. The
delineamento was in blocks entirely causalizados, in factorial outline [(3 x 2) + 1], acted by
three humidities (60, 70 and 80%) and two composed of mud (anaerobic mud and mud
sugarcane anaeróbio+bagaço), one more witness: absolute (anaerobic mud to 85%), with
four repetitions. After the dehydration of the anaerobic mud. The vermicompostagem
promoted the removal of the fecal coliformes in ali of the applied treatments. For the
helmintos, the largest reduction was obtained when of the use of the subsrratum without
sugarcane pulp, already in relation to the humidity tenor, the largest helmintos reduction
was gotten her/it a humidity of 70%. as for the tenor certain metais in the samples of the
vermicomposto, they were a lot below the permissible maximum for agricultural use of the
mud (USEPA, 1992). it was also Observed that, at the end of the experiment the
productivity of fetid Eisenia (red earthworm of Califónia) it was quite satisfactory in some
treatments.
