Embodiment 1

[0041] Example 1 (M2)

[0042] After adding 900ml of glucose simulated waste water and strain mixed solution in the anode chamber 14, add 900ml of phosphate buffer (pH=6.8) into the cathode chamber 13 earlier and expose to oxygen, after running for 24 hours, the buffer solution is replaced with 0.1mol / L copper sulfate solution. Then, operate according to the above steps S03-S04. During operation, the MFC output voltage is measured as a function of time, obtained as image 3 The circular icon curve shown in , the arrow indicates the time point of adding copper sulfate solution to the cathode chamber.

Embodiment 2

[0043] Example 2 (M3)

[0044] After adding 900ml of glucose simulated wastewater and strain mixture to the anode chamber 14, first add 900ml of phosphate buffer (pH=6.8) to the cathode chamber 13 without aeration, and then change the buffer solution to 0.1 after 48 hours of operation. mol / L copper sulfate solution. Then, operate according to the above steps S03-S04. During operation, the MFC output voltage is measured as a function of time, obtained as image 3 The square icon curve shown in , the arrow indicates the time point of adding copper sulfate solution to the cathode chamber.

Abstract

The invention provides a fuel cell system and a method of generating electricity and reducing heavy metal through sewage treatment. The system comprises a bioreactor, wherein the bioreactor comprises a negative chamber and a positive chamber, a negative electrode and a positive electrode are separately arranged in the negative chamber and the positive chamber, the two chambers are provided with microbial active material and are separated by a proton exchange membrane, the sewage is introduced to the positive chamber of which microbial active material is used to treat the sewage, the negative chamber contains heavy metal ion solution and reduces heavy metal ions, the inside of the positive chamber generates electrons and electrons, and the electrons migrate to the negative chamber through the proton exchange membrane so that current is generated between the two chambers in the reactor and the bioreactor can treat the sewage while generating electrical energy. In the system and method, the heavy metal ion solution is used as electron acceptor so that oxygen is not needed to be filled; and the whole system has simple structure, low cost and easy operation and heavy metal can be recycled from the negative solution.

Description

technical field [0001] The invention relates to a water treatment process, in particular to a fuel cell system using microbial reaction to treat sewage and generate electric energy, and a method for sewage treatment to produce electricity and reduce heavy metals. Background technique [0002] With the needs of the country or enterprises for green environmental protection and resource conservation, sewage (or waste) water treatment has become more and more popular. At present, the more effective and feasible sewage treatment usually adopts biological treatment methods. For example, traditional biological treatment processes use secondary sedimentation tanks to treat sewage. However, in the process of sewage treatment, after undergoing biochemical reactions, the sewage needs to pass through the secondary sedimentation tank before being discharged, resulting in a long sewage treatment process. In addition, the treatment process using the secondary sedimentation tank occupies ...
