<p>PURPOSE: A method for biological nutrient removal in effluent from wastewater treatment plant using anaerobic fermentation broth from organic wastes and high density microbial cell reactor is provided, which use organic acid, the anaerobic ferment liquid of organic waste, as carbon source, so that it can improve the final water quality to lower than 10 ppm of nitrogen, 1 ppm of phosphorus. CONSTITUTION: The method is characterized in that the final water quality is improved to lower than 10 ppm of nitrogen, 1 ppm of phosphorus by adding anaerobic fermentation broth of organic waste, the main product, by using high density microbial reactor of packing tower or modified reactor, and membrane type, wherein organic acid produced by anaerobic fermentation is mainly used but organic waste of low nitrogen and phosphorus content may also be used for treating wastewater of low C/N ratio with nitrogen being nitrite (NO2), nitrate (NO3), and phosphorus content being very low compared with nitrogen content.</p> |
