Thermophilic anaerobic digestion of sewage sludge

In view of the problems of poor sludge treatment effect, low cracking rate and poor VSS (volatile solid organic content) removal effect during sewage treatment, this paper optimizes the high-temperature anaerobic digestion method of sludge to effectively solve the above problems. Analyze the characteristics of sludge and stabilize the sludge; optimize the high-temperature anaerobic digestion process of sludge according to the problems of traditional methods. In order to verify the sludge treatment effect of the method in this paper, the control sludge was designed using the secondary sludge return sludge as the test sample. The results show that through the microscopic image of the sludge floc structure and the characteristics of the three-dimensional fluorescence spectrum, the method in this paper can effectively improve the cracking rate, and the VSS removal effect is obvious.
