Title: Comparison with Determing Methods of Organic Matter for Sludge Compost in Different Treatments
Abstract: the organic matter contents in deferent treatments of the sludge compost were determined by using Comparison the potassium dichromate with the burning method ,in order to understand changes of the organic matter contents for the Sewage sludge compost in adding different treatments of Fermentation accelerant and nutrient agents . The results showed as following: 1, the organic matter content for the sludge single composting at the end (53.36%) was lower 8.65% than at the beginning of composting(58.41%), the other corresponding treatment in composting all declined 12.37% -7.98%, indicating that the sludge compost would made The organic matter content are significantly reduced. 2, adding Fermentation accelerant into the sludge from 8% to 40%, the organic matter contents of their composting at the end increased more 2.94% ~ 19.73% than that of the single sludge compost. the highest organic matter content occurred in treatment 6 (sludge +40% Fermentation accelerant, 63.89 %). 3, at adding 24% Fermentation accelerant in the sludge ,as adding 8~32% of nutrient agents, the organic matter contents at the end of composting have been increased more 10.48%, 7.46%, 6.39% and 2.42% than the sludge single treatment , indicating that the sludge Adding 24% Fermentation accelerant and adding more nutrient agents can significantly improved the level of the organic content. 4, the organic matter contents for the sludge adding 30-50% nutrient agents have been declined 4.10% ~ 6.90% than the single-sludge compost treatment. 5, comparison of two measurement results showed that the potassium dichromate method is More advantages in measuring organic matter content of sludge compost than the burning method.
