Abstract:
This work proposes to assess the microbiological and physico-chemical characteristics and to quantify the heavy metals of the biosolids produced by the sewage treatment plant - STE, of the city of Toledo - State of Paraná - Brazil. The conclusion of this analysis is that the sewage sludge produced by the city's Sewage Treatment Plant can be categorized as a Type A sludge because it has low rates of total and thermotolerant coliforms. The physico-chemical characteristics of the dry sludge and the levels of heavy metals found proved to be an excellent indicator for the use of this material in agricultural activities.
Keywords: Biosolids, Sewage sludge, Sewage treatment.
