Embodiment 1

[0021] The method for the treatment of poultry wastewater by the novel mixed bacteria microbial fuel cell of the present embodiment, the mixed flora is Comamonas testosteroni and Desulfovibrio desulfurum mixed bacteria, and the specific treatment includes the following steps:

[0022] Step 1: Strain preparation and activation: activate Comamonas testosteroni and Desulfovibrio desulfuritis respectively and inoculate them into the culture medium, seal Comamonas testosteroni and culture on a shaker, and seal Desulfovibrio desulfuritis After cultivating in a constant temperature incubator until the end of the logarithmic phase;

[0023] Step 2: Inoculation of strains in the anode compartment of the microbial fuel cell: mix the cultured Comamonas testosteroni and Desulfovibrio desulfurum at a volume ratio of 1:1, and mix them with nutrient solution, buffer and sludge at a volume ratio of 1 :2:1:5 mixed, and then inoculated into the anode chamber of the microbial fuel cell, so that ...

Embodiment 2

[0033] The method for the treatment of poultry wastewater by the novel mixed bacteria microbial fuel cell of the present embodiment, the mixed flora is Comamonas testosteroni and Desulfovibrio desulfurum mixed bacteria, and the specific treatment includes the following steps:

[0034] Step 1: Strain preparation and activation: activate Comamonas testosteroni and Desulfovibrio desulfuritis respectively and inoculate them into the culture medium, seal Comamonas testosteroni and culture on a shaker, and seal Desulfovibrio desulfuritis After cultivating in a constant temperature incubator until the end of the logarithmic phase;

Abstract

The invention relates to a method for treating bird waste water by a novel mixed bacterium microbial fuel cell. The method includes the steps: activating and then inoculating comamonas testosteroni and desulfovibrio into culture solution; culturing the closed comamonas testosteroni in a shaker, culturing the closed desulfovibrio in an incubator at constant temperature until a last phase of a logarithmic phase; uniformly mixing the cultured comamonas testosteroni and the cultured desulfovibrio, mixing mixture, nutrient solution, buffer solution and sludge according to the volume ratio of (1-3):(2-5):(1-3):(3-7), inoculating mixture into an anode chamber of the microbial fuel cell, enabling floras to be suspended in anode solution or adhered on an anode, and standing to degrade the bird waste water and 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 mixed bacteria of the comamonas testosteroni and the desulfovibrio are applied to microbial fuel cells based on treatment of bird waste water, the degradation capability of the bird waste water can be effectively improved,and electric energy is generated.

Description

technical field [0001] The invention belongs to the field of waste water treatment, in particular to a method for treating bird waste water with a novel mixed bacteria microbial fuel cell. Background technique [0002] Water pollution and energy consumption have always been hotly debated topics. Traditional water treatment methods include physical, chemical and biological methods, among which physical methods include: sedimentation, screening, air flotation, centrifugation, etc., chemical methods include: coagulation, neutralization, redox, adsorption, etc., biological methods include active Sludge, biofilm, yang-yang biological treatment and other methods. However, traditional wastewater treatment technologies consume a lot of energy when treating wastewater. In addition, the traditional wastewater treatment technology is not effective in treating poultry wastewater. At present, there is no treatment technology that can well solve the problem of poultry wastewater polluti...
