| titleOfInvention | Method for recovering hydrogen from high ammonia nitrogen waste liquid at normal temperature without external voltage |
| abstract | The invention discloses a method for recovering hydrogen from high ammonia nitrogen waste liquid at normal temperature without external voltage, which comprises the following steps: 1) weighing sodium nitrite, sodium carbonate and glucose, adding the sodium nitrite, sodium carbonate and glucose into the high ammonia nitrogen waste liquid, and stirring the mixture under a sealed condition until the mixture is completely dissolved to obtain an anaerobic ammonium oxidation bacterium domestication liquid; 2) mixing the anaerobic ammonium oxidation bacterium domestication liquid with anaerobic sludge to obtain starting mixed slurry; 3) adding the starting mixed slurry into an anode chamber of a hydrogen recovery reaction device, and continuously and slowly stirring; 4) and irradiating the anode electrode with visible light for 2-4 hours every 6-10 hours, and finishing the reaction process when the volume concentration detection value of hydrogen at the air guide hole of the cathode chamber is lower than 1%. According to the invention, three technologies of photocatalysis, anaerobic ammonia oxidation and microbial fuel cell are coupled, so that the ammonia nitrogen dehydrogenation effect is improved, the hydrogen conversion efficiency is improved, the hydrogen energy recovery of the high ammonia nitrogen waste liquid is realized under the condition of no external voltage loading or temperature rise, and the ammonia nitrogen is converted into nitrogen and safely discharged to the air. |
