Treatment method of wastewater containing high-concentration polyethylene glycol PEG-10000

The invention discloses a treatment method of wastewater containing high-concentration polyethylene glycol PEG-10000, and belongs to the technical field of polyethylene glycol PEG-10000 wastewater treatment method.The treatment method comprises the following steps that S1, anaerobic sludge is cultured and domesticated; step S2, preparation of an anaerobic degradation test of polyethylene glycol PEG-10000 wastewater is carried out; s3, carrying out anaerobic degradation on the polyethylene glycol PEG-10000 wastewater with the same pH value and different concentrations; and step S4, anaerobic degradation of the polyethylene glycol PEG-10000 wastewater with the same concentration and different pH values. According to the method, the reinforced anaerobic granular sludge is adopted to degrade the polyethylene glycol PEG-10000 wastewater under the alkaline condition, the COD degradation rate of the polyethylene glycol PEG-10000 wastewater is increased, the gas production rate is increased, and the treatment time is
