Embodiment 1

[0054] This example is intended to illustrate a reactor configuration for a packing reaction system for enhanced anaerobic digestion and its operating method.

[0055] In this embodiment, it is sufficient to select a space that meets the domestication requirements for the biofiller acclimation area. The anaerobic digestion reactor is composed of a biofiller arrangement area and an anaerobic digestion reaction area, both of which are integrated in such as figure 2 In the reaction device shown, the biological filler arrangement area is arranged in three layers, and the enhanced methanogenic biological filler, the enhanced acidification biological filler, and the enhanced hydrolysis biological filler are arranged in the first layer, the second layer, and the third layer in sequence. Among them, 1# filler is magnetite biological filler, 2# filler is hematite biological filler, and 3# filler is iron-carbon micro-electrolysis biological filler. The detailed schematic diagram of the...

Abstract

The invention relates to a filler reaction system for strengthening anaerobic digestion. The filler reaction system comprises a biological filler domestication area, a biological filler arrangement area and an anaerobic digestion reaction area which are connected in sequence; in the biological filler domestication area, biofilm formation domestication and adaptability verification of various fillers are completed, and reinforced biological fillers passing verification are obtained; in the biological filler arrangement area, reinforced biological fillers passing verification are specifically selected and combined, and layered arrangement is carried out, so that a layered arrangement reinforced anaerobic digestion filler combination is obtained; and in the anaerobic digestion reaction area, anaerobic digestion reaction under biological filler reinforcement is carried out based on a hierarchically arranged reinforced anaerobic digestion filler combination. Compared with the prior art, the requirements of precision, high efficiency, integration and sustainability of the novel packed reactor are met, the anaerobic digestion strengthening capacity and efficiency of the packed reactor can be effectively improved, and good engineering application prospects are achieved.

Description

technical field [0001] The invention relates to the field of environmental protection and resource recovery, in particular to a packing reaction system for strengthening anaerobic digestion. Background technique [0002] In the field of sewage and organic waste treatment, the synergistic effect of pollution reduction and carbon reduction, and the strengthening of resource and energy recovery are the key links to achieve carbon emission reduction and even negative carbon emission. Anaerobic digestion technology is a widely used biological treatment green technology in the treatment of sewage, sludge and various organic wastes. It can realize the recovery of biomass resources and energy while completing the harmless treatment of pollutants, and the generated biogas can be used as a renewable energy source. Energy can effectively replace fossil energy such as petroleum, and is an important technical guarantee to support the construction of ecological civilization and sustainabl...
