Embodiment 1

[0055] A three-dimensional electrode photoelectric microbial fuel cell reactor, comprising an anode chamber 2 and a cathode chamber 14 separated by a proton exchange membrane 17, an anode 8 is arranged in the anode chamber, a cathode 11 is arranged in the cathode chamber, and the anode and the cathode are externally connected to variable resistors by wires 22 connected, the anode chamber is divided into upper and lower parts by the photocatalytic plate 4, the upper part is the photocatalytic area, the lower part is the microbial anaerobic digestion area, the cathode chamber is divided into left and right parts by the partition 15, and the bottom of the partition is opened Vent 16;

[0056] The ultraviolet light sources 9 and 19 are controlled by a switch, and there are two places respectively located above the anode chamber and on the side of the cathode chamber. As a preference, the top of the anode chamber and the side of the cathode chamber irradiated by the ultraviolet ligh...

Embodiment 2

[0072] A biogas quality-enhancing and efficiency-enhancing method using three-dimensional electrode photoelectric microbial fuel cell technology (using straw and poultry manure as raw materials):

[0073] First, biofilm formation is carried out without ultraviolet light irradiation: turn off the ultraviolet light sources 9 and 19, add the domesticated activated sludge solution or the special microbial bacterial solution cultivated for refractory organic matter into the microbial anode chamber 2, and make it Immerse the biofilm carrier (granular biochar with a particle size of 3 to 5 mm), and circulate in the microbial anode chamber 2 through the circulation pump 5. After inoculation by adsorption, a mature biofilm will be formed after 5 to 10 days, and excess active pollution will be discharged. Mud or liquid.

[0074] After the biofilm is formed, take the air-dried agricultural and forestry waste straw and chop it to about 3cm, and at the same time take fresh livestock and po...

Abstract

The invention relates to a three-dimensional electrode photoelectric microbial fuel cell reactor, and a marsh gas quality and effectiveness improving method. The three-dimensional electrode photoelectric microbial fuel cell reactor mainly comprises an anode chamber and a cathode chamber separated by a proton exchange membrane, wherein the anode chamber is divided into an upper part and a lower part by a photocatalytic plate; the upper part is a photocatalytic region while the lower part is a fluidized bed biological membrane microbial anaerobic digestion region; due to the function of the photocatalytic plate, the biological membrane at the lower part is prevented from being hurt by ultraviolet lights, and coupling of the photocatalysis and microbial anaerobic digestion is realized in the same reactor; the cathode chamber is divided into a left region and a right region by a partition plate with vent holes at the bottom; the left region is a photocatalytic CO2 methanation region; granular charcoal filled in the cathode chamber has a certain purification function, and the marsh gas generated by the reactor finally is output from the right region. According to the marsh gas quality and effectiveness improving method, efficient and rapid disposal of degradation-resistant organic materials, improvement of the microbial fuel cell electricity production efficient, and efficient and high-quality production of the marsh gas are realized.

Description

technical field [0001] The invention relates to microbial fuel cell technology, photocatalysis technology, three-dimensional electrode technology, biofilm reactor technology with biochar as a carrier, fluidized bed anaerobic digestion technology and biogas production and utilization technology, and specifically relates to a three-dimensional electrode photoelectric microbial fuel A battery reactor and a method for improving the quality and efficiency of biogas. Background technique [0002] Biogas fermentation technology, through anaerobic fermentation of organic waste such as crop stalks, livestock and poultry manure, the biogas produced is used in farmers' daily life and production to replace rural living energy, and can be used for heating and power generation to reduce the consumption of fossil energy. In today's energy shortage and environmental pollution, it has unique significance. However, traditional anaerobic fermentation reactors have problems such as low degrada...
