Embodiment
[0040] After the wastewater (such as wastewater produced by livestock and poultry breeding) is pretreated and advanced oxidation treatment, 90% of the COD is removed. At this time, the sewage enters the bioreactor from the water inlet pipe 10, and the COD of the water inlet is greater than 1000mg / L; the water inlet pipe 10 The liquid flow sensor 20 is set, the water inlet pump is connected to the PCL control system, the flow rate of the water inlet can be controlled through the PCL control system, and the sewage enters the bioreactor, and the degradation of organic matter and the accumulation of methane are first carried out through the anaerobic reaction zone, and the microorganisms are attached to the graphene to improve the bioreactor. On the biological carrier of the sponge, on the one hand, the biological carrier provides the growth space for the microorganisms, and promotes the maintenance of the shape of the granular anaerobic sludge; on the other hand, it absorbs the org...
