| Descripción : | The purpose of the treatment of domestic sewage water, is to remove all harmful pollutants that are contained in an effluent, causing formation of raw sludge which has characteristics of hazardous waste. Taking into account that if the domestic residual sludge is subjected to a stabilization process, it is possible to reuse it for agricultural purposes, retrieval of eroded soil, fertilizers, among others. The present titration work was carried out in the months of October and December 2017, in which the biological sludge from the treatment plant of domestic sewage water, Vacuumtruck Services S.A., was used. Located in the province of Francisco de Orellana. The biological sludge was subjected to a thickening process, bio accelerator addition (black earth), nutrient dosage (NPK) and finally to a mesophilic anaerobic digestion, to which a study was carried out by means of a completely randomized design (DCA). The analysis of results is divided into three components: (1) temperature and pH follow ups, as guidelines for the mesophilic anaerobic digestion process; (2) the SV / ST ratio criteria that determine the biosolid stabilization and (3) the study of coliforms and heavy metals that resolve a potential reuse of biosolids. In which was concluded that the addition of a bio accelerator optimizes the mesophilic anaerobic digestion process since it reduced 33.5 percent humidity, and with a nutrient dosage (NPK), accelerates the stabilization time. Obtaining a biosolid class A, which was stabilized in 7 days and reduced 99.3 percent of total coliforms. |
