| Özet |
| The aim of this study was to evaluate the enzyme activities such as urease, phosphatase and arylsulphatase during vermicomposting of sewage sludge (SS) with hazelnut husk (HH) and cow manure (CM) by earthworm Eisenia fetida. The growth and reproduction of E. fetida were monitored in a range of different feed mixtures for 90 days in the laboratory under controlled experimental conditions at 25±0.5 0C. In the study two investigated approaches were:(1) growth and reproduction of E. fetida up to 90 days in different feed mixtures and;(2) evaluation of vermicomposting of SS, HH and CM mixtures after 90 days in terms of enzyme activities of the products. The maximum earthworm biomass was recorded in 20% SS+ 40% HH+ 40% CM feed mixtures. The results indicated that extracelular enzyme activities significantly increased with increasing vermicomposting time. Our trials demonstrated vermicomposting as an alternative technology for the recycling and environmentally safe disposal/management of SS using an epigeic earthworm E. fetida if mixed with HH and CM. |
