| description | The invention discloses a method for reinforcing hydrothermal reaction of residual sludge by zero-valent iron for reducing resistance genes. The method is characterized in that after anaerobic treatment on sewage, the sewage is subjected to aerobic treatment under the action of zero-valent iron, and through the reaction under aeration conditions, the EPS content of sludge is reduced; then secondary sedimentation is carried out, and residual activated sludge containing iron is concentrated by gravity sedimentation; the concentrated iron-containing sludge is preheated, and then heated to undergohydrothermal reaction; after the reaction is finished and the sludge is cooled, centrifugal dehydration is performed to obtain a hydrothermal liquid and sludge carbon; and the hydrothermal liquid issubjected to Fenton oxidation reaction. The method of the invention adds zero-valent iron to an activated sludge system for enhanced biological treatment, and the generated iron-containing residual sludge is subjected to high- |
