Abstract:

Composting is a low-cost option and a relatively simple process for organic solid wastes stabilization. In this sense, the aim of this study was to evaluate the textile sludge bioestabilization process disposed with napier grass (Pennisetum purpureum Schum.) using swine wastewater (SW) as a microorganisms inoculation source and to correct moisture. The treatments with SW used were: 60% textile sludge + 40% napier grass (T1); 50% textile sludge + 50% + napier grass (T2); 40% textile sludge + 60% napier grass (T3); 100% textile sludge (T4); with four replicates in a completely randomized design. The parameters that characterize the compost quality obtained in each plot (pH, U, OM, C, N, P, K, Ca⁺², Na⁺, C/N) after the biostabilization process, were submitted to normality test and after, to analysis of variance and mean comparison test, using the Scott-Knott test at 5% significance level. From the CO₂ emission results and the Mineralized Carbon Percentage obtained, regression curves were adjusted and comparison curves tests were made in order to compare the bioestabilization dynamics between treatments. From the results and the experimental conditions was possible to conclude that the treatments with 60% textile sludge + 40% napier grass, 50% textile sludge + 50% napier grass and 40% textile sludge + 60% napier grass presented similar biostabilization final rates and different from treatment 100% textile sludge; the degradation percentages found for treatments 60% textile sludge + 40% napier grass + SW, 50% textile sludge + 50% + napier grass + SW, 40% textile sludge + 60% napier grass + SW and 100% textile sludge + SW were 16.28%, 15.93%, 14.85% and 11.53%, respectively.
