Water treatment device combining microbial fuel cells with membrane technology

Abstract

The invention discloses a water treatment device combining microbial fuel cells with a membrane technology. A cathode and a membrane module are arranged in a cathode chamber, and the membrane module enters into a water tank through a pipeline. An aeration pump is connected with an aeration head arranged at the bottom in the cathode chamber, and an anode is arranged in an anode chamber. After a voltage meter is connected with load in parallel, one end of the voltage meter is connected with the anode, and the other end of the voltage meter is connected with the cathode. A channel is arranged between the anode chamber and the cathode chamber, and a partitive membrane is arranged on the channel. An exhaust vent is formed in the top of the anode chamber. The bottom of the cathode chamber is connected with a regulating chamber through a pipeline, and the regulating chamber is connected with the bottom of the anode chamber through a pipeline. The water treatment device not only can carry outwastewater treatment for reuse but also can use the wastewater as an energy source to generate electricity, strong water is not generated, and the environment is not polluted. The membrane treatment efficiency is high, and the quality of effluent water is good and stable. A method has the advantages of simpleness, easiness in operation, less occupied area and low investment and maintenance cost. According to different requirements, the treatment capability is designed. The water treatment device can adapt to sequencing batch processing and continuous flow processing.

Description

technical field [0001] The invention relates to water treatment technology, material separation technology, energy utilization and environmental protection, and in particular to a water treatment device combining microbial fuel cell and membrane technology. Background technique [0002] Microbial fuel cell (MFC) is a new technology that uses the catalytic action of microorganisms to convert chemical energy in organic matter into electrical energy. The basic principle is: in the anaerobic environment of the anode chamber, organic matter decomposes under the action of microorganisms and releases electrons and protons. A current is formed at the cathode, and protons are transferred to the cathode through the proton exchange membrane, and the oxidant (usually oxygen) obtains electrons at the cathode and is reduced and combined with protons to form water. The reaction chamber of traditional MFCs is usually divided into an anode chamber and a cathode chamber by a separation membr...

Problems solved by technology

[0007] At present, the research on MFC is still mainly at the laboratory level. The currently reported forms of MFC are not suitable for separate and efficient wastewater treatment in terms of structure and operation characteristics, which limits the application of MFC in wastewater treatment.

The combination of MFC and membrane separation technology has not been reported
