| titleOfInvention | Method for improving anaerobic methane production of propionic acid |
| abstract | The invention discloses a method for improving anaerobic methanogenesis of propionic acid, and belongs to the technical field of environmental protection. The method comprises the following steps: firstly, adding a propionic acid anaerobic reaction culture medium containing ultrapure water, sodium propionate, inorganic salt and trace elements into a reactor, and then adding inoculated sludge and a composite material Met @ Fe 3 O 4 And then adjusting the pH value of the system in the reactor to 7.0 +/-0.2, blowing off oxygen in the reactor by using nitrogen to enable microorganisms in the reactor to be in an anaerobic environment, and then carrying out propionic acid anaerobic methanogenesis reaction at the temperature of 30 +/-2 ℃ for 31 d. The method is simple and convenient to operate, and the composite material Met @ Fe which is easier to contact with microorganisms is added into the propionic acid anaerobic methanogenesis system 3 O 4 The method can strengthen the direct electron transfer process, further promote the generation of methane and the degradation of propionic acid, improve the generation amount of methane and the degradation rate of propionic acid, and reduce the accumulation of propionic acid in an anaerobic digestion system. |
