Abstract

The invention provides a microbial fuel cell. The microbial fuel cell comprises a first positive electrode chamber, a negative electrode chamber and a second positive electrode chamber which are sequentially arranged and are respectively separated by a positive ion exchange membrane and a negative ion exchange membrane, wherein the first positive electrode chamber communicates with the second positive electrode chamber, the first positive electrode, a negative electrode and a second positive electrode are respectively connected, microorganism or active sludge having power generation activity is grafted onto the first positive electrode, a non-biological catalyst is arranged on the negative electrode, microorganism or activated sludge having nitration activity is grafted into a negative electrode liquid in the negative electrode chamber, and microorganism or activated sludge simultaneously having power generation and denitrification activity is grafted onto a second positive electrode.By the microbial fuel cell, the most appropriate environment of power generation efficiency, nitration efficiency and denitrification efficiency is ensured, and effective removal of nitrogen in wastewater is also ensured on the basis that an organic matter in the waste water is effectively removed.

Description

technical field [0001] The invention relates to the technical field of microbial electrochemistry, in particular to a microbial fuel cell. Background technique [0002] At present, with the rapid development of my country's economy, increasingly frequent industrial production activities and human activities have caused serious water pollution and consumed a lot of energy; today's water pollution and energy shortage have become the key issues restricting my country's sustainable development . [0003] Microbial Fuel Cell (MFC) is a new type of clean energy technology that utilizes electrogenic microorganisms to degrade organic pollutants in water and convert their chemical energy into electrical energy in situ. The use of microbial fuel cells to treat wastewater not only achieves the effective removal of organic matter, but also directly converts chemical energy into electrical energy, which not only solves the shortcomings of high energy consumption and large sludge producti...
