【 摘 要 】

This research aims to monitor the humification process of domestic sewage sludge resulted from the vermicomposting, evaluating, also, the possibility of using the final product (vermicompost) in agricultural soils. The monitored chemical variables during the 90 days of vermicomposting were: humidity rate, organic matter content, nitrogen and phosphorus content, pathogenic organisms concentration, total organic carbon, acidity, CEC, C/N ratio, CEC/TOC ratio, and humic and fulvic acids content. The change in these variables during the vermicomposting process showed that this technique is effective for use in the maturation of the residue.
