[Effect of organic solvent on production of organic acids from municipal sludge].
Organic acids are important chemicals. Municipal sludge can be reused by anaerobic fermentation, from which organic acids could be obtained with liquid-liquid extraction and useful substances be produced. Based on the determination of optimum organic solvent and extractant, it effect on production of volatile fatty acid (VFA) from municipal sludge was investigated in this research. The results showed that the proper organic solvent and extractant were sulfonated kerosene and trialkyl phosphine oxide. And, the VFA production was improved by a slight amount of sulfonated kerosene.
