Method for Biological Nutrient Removal in Effluent from Waste Water Treatment Plant Using Anaerobic Fermentation Broth from Organic Wastes and High Density Microbial Cell Reactor

摘要

The invention relates to a method for removing nitrogen and phosphorus in utilizing the produced organic acid as a carbon source through anaerobic fermentation waste water, sewage and waste water (hereinafter referred to as "sire number") from the organic waste effectively.; The present invention for solving the country Majesty carbon (C) / nitrogen (N) ratio is low, NO x removal, problems dephosphorization is not smooth. A high concentration in a manner that commonly adopted in our country, and the effluent water of the sire can be treated with activated sludge process is now improving the water quality by not more than 1 ppm of nitrogen 10 ppm, developed based on that the maximum nitrogen 50 ppm, of 5 ppm in the use of microbial method. Use a low acid without the use of methanol as a carbon source and a costly process that minimizes the number of large tank to another to save the facility fee. Concrete, for example, high-concentration microbe entity if the packed column the water quality of the sewage was added to the organic acids produced by anaerobic fermentation from organic waste in the effluent of nitrogen 28.6 ppm, of 0.12 ppm water in the packed tower inlet water was nitrogen 28.7 ppm, of 0.33 this is ppm. Packed column water quality of effluent after passing through the nitrogen and the nitrogen as 7.9 ppm, 0.20 ppm which is the removed, respectively 72.5%, 39.4%. At this time, depending on the carbon / nitrogen ratio it was denitration rate can be adjusted up to 66.7% -100% NO x removal capability of the packed column was a nitrogen (N) based on the 1.01 kg / (㎥ · day). The present invention with the applicable as well as the cost savings and convenience to the advanced treatment of the sire can be possible applied to a water quality improvement of effluent Majesty water treatment plant using the activated sludge method which is operated in an existing in Majesty water treatment plant to be built as a new claim It will be a ball.
