Method for promoting anaerobic digestion of excess sludge through pretreatment of ultrasonic waves and hydrogen peroxide
InactiveCN102424506AGood cracking effectHelp brokenWaste based fuelBiological sludge treatmentChemistryAerobic digestion
Belonging to the technical field of solid waste treatment, the invention relates to a method for promoting anaerobic digestion of excess sludge through pretreatment of ultrasonic waves and hydrogen peroxide. The method comprises: subjecting the excess sludge of an urban sewage treatment plant to gravity thickening, then adding a certain amount of hydrogen peroxide, conducting rapid stirring and sending the sludge into an ultrasonic reactor for ultrasonic treatment, in which the combined action of ultrasonic waves and hydrogen peroxide destroys the bacterial cell wall structure of the sludge, thus leading to leakage of the cell contents and content increase of dissolved organic matters in water, then sending the treated sludge into an anaerobic digestion reactor for subsequent mesophilic anaerobic digestion; delivering the biogas generated from anaerobic digestion to a gas collection gas for comprehensive utilization. After treatment, the concentration of SCOD (soluble chemical oxygen demand) in the liquid phase sludge can be increased by 23.83 times to 41.18 times, the biogas output can be increased by 17.40%-55.37%, and the methane content of the biogas can be increased by 10%-20%, thus reducing the energy consumption of ultrasonic treatment. For sewage treatment plants of different scales, only by making corresponding modification on existing facilities can good effects be achieved.
