Embodiment 1

[0021] The method for treating chicken farm wastewater by the desulfovibrio microbial fuel cell in this embodiment includes the following steps:

[0022] Step 1: Strain preparation and activation: Activate the preserved Desulfovibrio and inoculate it into the culture solution. After airtight, culture it in a constant temperature incubator at a culture temperature of 25-35°C until the end of the logarithmic phase;

[0023] Step 2: Inoculation of bacteria in the anode chamber of the microbial fuel cell: mix the cultured bacteria liquid with the nutrient solution, buffer and sludge in a volume ratio of 1:2:1:5, and then inoculate the microbial fuel cell anode chamber to make The bacteria liquid is suspended in the anolyte or attached to the anode. The bacteria liquid is used to degrade the chicken farm wastewater and produce electrons and protons. The electrons reach the cathode through the external circuit and form a current loop with the protons that reach the cathode through the int...

[0033] The method for treating chicken farm wastewater by the desulfovibrio microbial fuel cell in this embodiment includes the following steps:

[0034] Step 1: Strain preparation and activation: Activate the preserved Desulfovibrio and inoculate it into the culture solution. After airtight, culture in a constant temperature incubator until the end of the logarithmic phase;

[0035] Step 2: Inoculation of strains in the anode chamber of the microbial fuel cell: mix the cultured bacterial solution with nutrient solution, buffer and sludge in a volume ratio of 2:2:2:6, and then inoculate it into the anode chamber of the microbial fuel cell to make The bacteria liquid is suspended in the anolyte or attached to the anode. The bacteria liquid is used to degrade the chicken farm wastewater and produce electrons and protons. The electrons reach the cathode through the external circuit and form a current loop with the protons that reach the cathode through the intermediate diaphragm to gen...

Abstract

The invention relates to a method for treating chicken farm waste water by a desulfovibrio microbial fuel cell. The method includes the steps: activating and then inoculating desulfovibrio into culture solution, and culturing the closed desulfovibrio in an incubator at constant temperature until a last phase of a logarithmic phase; mixing the cultured bacterial solution, nutrient solution, buffersolution and sludge according to the volume ratio of (1-4):(1-4):(1-2):(4-7), inoculating mixture into an anode chamber of the microbial fuel cell, enabling the bacterial solution to be suspended in anode solution or adhered on an anode, standing to degrade the chicken farm waste water by the aid of the bacterial solution to generate electrons and protons, and enabling the electrons to reach a cathode through an external circuit and penetrate a middle diaphragm to reach protons of the cathode to form a current loop to generate power; updating anode solution once every 2-7 days, and retaining 10% of original mixture in the original anode chamber. The method has the advantages that the desulfovibrio is applied to microbial fuel cells based on treatment of chicken farm waste water, the degradation capability of the chicken farm waste water can be effectively improved, and electric energy is generated.

Description

Technical field [0001] The invention belongs to the field of wastewater treatment, and particularly relates to a method for treating chicken farm wastewater by a desulfovibrio microbial fuel cell. Background technique [0002] The issue of water pollution and energy consumption has always been a hot topic. Traditional water treatment methods include physical, chemical and biological methods. Among them, physical methods include: precipitation, screening, air flotation, centrifugation, etc., chemical methods include: coagulation, neutralization, redox, adsorption, etc., biological methods include activity Sludge, biofilm, and Yangyang biological treatment methods. However, the traditional wastewater treatment technology has great energy consumption when treating wastewater. In addition, traditional wastewater treatment technologies are not effective in treating chicken farm wastewater, and there is no treatment technology that can well solve the problem of chicken farm wastewate...
