METHOD FOR PREPARING ANAEROBIC FERMENTATION LIQUOR FROM ORGANIC WASTES FOR USE IN NUTRIENT REMOVAL |
摘要 |
<p>PURPOSE: A method for preparing an anaerobic fermentation liquor from organic wastes for use in nutrient removal as carbon source is provided. CONSTITUTION: The preparation method is characterized in that organic wastes are converted into an anaerobic fermentation liquor that includes organic acids having 2 to 6 of carbon numbers through semi continuous anaerobic fermentation, wherein pH is kept within 5.3 to 6.5; reaction temperature is held within 30 to 45 deg.C; hydraulic retention time is within 6 to 12 days; feed rate of organic wastes is 7 to 13 g/L·day. The anaerobic fermentation liquor is characterized in that organic acid concentration thereof is 20 to 35 g/L; dissolved COD concentration is 30,000 to 50,000; the portion of organic acid in dissolved COD is 70 to 95 %; the portion of acetic acid in organic acid is 20 to 55 %; and the portion of butyric acid in organic acid 10 to 25 %.</p> |
