Abstract

The invention discloses an anaerobic digestion-biological electrolysis coupling reactor residual sludge treatment device, and belongs to the technical field of sludge hydrolysis carbonization. The anaerobic digestion-biological electrolysis coupling reactor residual sludge treatment device is characterized in that a motor and a gas collecting bag are arranged on the top of a tube body, a sludge outlet is formed in the bottom of the tube body, an anaerobic digestion area A is provided with a sludge inlet, a sludge inlet pump is arranged at the sludge inlet, the anaerobic digestion area is internally provided with a stirring device, the stirring device is connected with an output end of the motor, an ozone generator is arranged on the inner wall of the anaerobic digestion area, and the anaerobic digestion area is communicated with the sludge outlet. The anaerobic digestion-biological electrolysis coupling reactor residual sludge treatment device has the advantages that the problems of constraint, the failure of being rationalized and secondary pollution when sludge is traditionally treated are solved, and a novel renewable energy is generated.

Description

technical field [0001] The invention relates to the technical field of sludge hydrolysis and carbonization treatment, in particular to an anaerobic digestion-bioelectrolysis coupled reactor residual sludge treatment device. Background technique [0002] With the improvement of living standards, the treatment of domestic sewage has become more and more important, and the output of urban sewage has also increased significantly. Since urban sewage treatment plants generally use the activated sludge method for biological treatment of domestic sewage, so With the improvement of organic matter in influent sewage and the increase of sewage treatment volume, the treatment and disposal of sludge has received more and more attention and has become more and more important. In municipal sewage treatment plants, sludge is a by-product of the biochemical treatment of sewage. The nature of sludge is complex, and it contains heavy metal ions and some pathogenic bacteria, so the treatment a...
