| titleOfInvention | A system and process for simultaneous denitrification and decarbonization of swine wastewater |
| abstract | The invention provides a method for simultaneous denitrification and carbon removal of pig-raising wastewater, which organically combines denitrification, methanation, short-path nitrification and anaerobic ammonia oxidation through a two-stage reactor of EGSB-SMD and EGSB-PNA. The SMD-PNA system maximizes the advantages of functional bacteria in the reactor, realizes the almost complete removal of ammonia nitrogen and organic carbon, and is easy to cultivate, and the whole process has strong stability and controllability. In EGSB-SMD, the anoxic-anaerobic structure of granular sludge is conducive to the synergistic symbiosis of methanogens and denitrifying bacteria, while taking into account the removal of NO 2 ‑ ‑N and NO 3 ‑ ‑N in raw water and return sewage It has a higher COD removal load, and the SMD internal reflux device and PNA external reflux device dilute the influent concentration and reduce substrate inhibition. In EGSB‑PNA, the internal recirculation device increases the upward flow rate, which promotes the formation of larger granular sludge, and the combined soft and semi-soft packing inside the reactor promotes the formation of biofilm and adheres tightly, thus maintaining the interior of the reactor. The biomass maintained the stable operation of the CANON process. |
