specific Embodiment approach 1

[0013] Specific embodiment one: (see Fig. 1) the microbial fuel cell in the present embodiment is made up of simplified body 1, cathode 2, anode 3, first apron 4, anode cover plate 5, cathode cover plate 6, second apron 7, The anode wire 8 and the cathode wire 9 are composed. One end of the microbial fuel cell is open and the other end is closed; a fuel chamber 12 is formed between the cathode 2, the anode 3 and the cylinder 1, and the distance between the anode 3 and the cathode 2 is not less than 1 cm. There are grooves inside the two ends of the cylinder body 1. The anode 3 and the second rubber ring 7 are installed in the groove at the closed end of the simplified body 1. The port at the closed end of the cylinder body 1 is closed with the anode cover plate 5. The second rubber ring 7 is located between the anode 3 and the The anode cover plate 5 acts as a seal, the groove at the opening end of the cylinder 1 is equipped with the cathode 2 and the first apron 4, the port a...

Abstract

The invention provides a microbiological fuel cell and a method for treating beer waste water using the same, which belongs to the technical field of sewage treatment. The invention solves the problems of the prior beer waste water method, such as large influence of temperature on treatment efficiency, high cost and high COD of discharged water. The inventive microbiological fuel cell has an opened end and a sealed end, comprises a cathode fixed at the opened end, an anode fixed at the sealed end, and a fuel chamber formed between the cathode / anode and a barrel shell (1), without any cation exchange membrane being added between the cathode and the anode. The invention utilizes the indigenous microorganisms in the beer waste water as a bacterial source, after starting a reactor, to degrade organic substances and simultaneously generate power energy by using microbial decomposition. In the invention, the COD removal rate of the beer waste water is above 85 percent (up to 98 percent), the COD content in the discharge water is less than 450mg / L (minimum 20mg / L). The invention has the advantages of simple process and equipment structure, low cost, high efficiency, and less influence of temperature on the treatment effect and power yield; and is suitable for the large-scale promotion and application.

Description

technical field [0001] The invention belongs to the field of sewage treatment, and in particular relates to a microbial fuel cell and a method for treating beer wastewater, which can obtain electric energy while treating organic matter in the beer wastewater. Background technique [0002] Beer is a major discharge of wastewater and pollutants in the brewing industry. According to the statistical survey results of the State Environmental Protection Administration, the discharge of beer wastewater in 2002 was about 270 million cubic meters, and the annual discharge of COD was about 29,000 tons. Beer wastewater accounted for the largest share of industrial wastewater discharge in the country. 1.3% of the total, and the discharged COD accounts for 0.5% of the total COD discharge in the national industrial wastewater. Although the beer industry has made great progress in clean production and pollution prevention and control, and the discharge of waste water per ton of product has...
