Etiketle | Özet: | In recent years, the pork industry in Ecuador has experienced significant growth, leading to an increase in the generation of solid waste due to production and maintenance systems. Inadequate waste management practices have significantly impacted the soil. Therefore, this study addresses the treatment of sludge from the ESPAM MFL Pig Farm through an anaerobic digestion process known as biological stabilization. The investigated variables included the types of waste used (fruit and vegetable peels) as co-substrates, sucrose (commercial brown sugar) as a biocatalyst, and the incorporation of anaerobic microorganisms BIOMERK ® AR. A 2^3 factorial experimental design was employed, consisting of 8 treatments with 3 replications each. The most effective treatment in biological stabilization was T4, which achieved a reduction in the SV/ST ratio of 40.1% in the fifth week of the process. Additionally, various indicators were monitored every 72 hours. The pH ranged from 5.56 to 7.21, while the temperature in the sludge remained between 26 °C and 28 °C. Quantification of fecal coliforms was also conducted, meeting EPA criteria for classifying the sludge as Class B. The C/N ratio for the initial sludge was 0.528% and 9.297%, whereas for treatment T4, it was 0.244% and 13.772%. Importantly, this research was based on the methodology established by the EPA, known as the "503 Biosolids Rule." According to this regulation, the biological stabilization process is considered effective if the volatile solids/total solids ratio achieves a minimum reduction of 60%. |
