Method for treatment of high nitrogen-organic waste for improving efficiency of bio-gas generation under anaerobic digestion

摘要

The present invention relates to a treatment method for enhancing anaerobic biogas production efficiency of a high concentration nitrogen-containing organic waste, comprising: hydrothermally decomposing an organic waste to obtain a hydrolysis product (step 1); Compressing the hydrolyzate to obtain a desorption solution (step 2); Removing the ammonia nitrogen from the desalination solution by using an electro-adsorption device (step 3); And anaerobically digesting the desorbed liquid from which the ammonia nitrogen has been removed (Step 4); And the ammonia nitrogen component contained in the desalination solution is effectively removed by flowing the desorbed solution through hydrothermal decomposition and compression of the organic waste into the electroabsorbing apparatus at a temperature of 40 to 80 ° C to remove the ammonia nitrogen component from the anaerobic microorganism It is possible to prevent anaerobic digestibility and to increase the amount of biogas generated since it can prevent the activity from being inhibited in advance.
