Multiple-effect photosynthetic microorganism fuel battery and implementation method thereof

Abstract

The invention relates to a multiple-effect photosynthetic microorganism fuel battery and an implementation method thereof. A cathode chamber, a desalting chamber and an anode chamber are sequentially arranged in a case body and are separated by anode films; extracellular electrogenesis bacteria are added in the anode chamber, and an anode electrode is inserted therein; microalgae are added in the cathode chamber, and a cathode electrode coated with a catalyst coating is inserted therein; a set of capacitor pole plates is arranged in the desalting chamber, the capacitor pole plates are divided into positive capacitor pole plates and negative capacitor pole plates, the positive capacitor pole plates and the negative capacitor pole plates are arranged alternately, an insulation layer is arranged between every two adjacent capacitor pole plates, the negative capacitor pole plates are connected with the anode electrode, and the positive capacitor pole plates are connected with the cathode electrode; and O2 is produced in the cathode chamber, CO2, electrons and protons are produced in the anode chamber, and the protons pass through the anode films to reach the cathode chamber and be subjected to electrochemical action with the O2 in the presence of a catalyst so as to form a stable oxide. According to the invention, the desalting rate can be increased; and meanwhile, nitrogen and phosphorus can be effectively removed.

Description

technical field [0001] The invention relates to the technical field of microbial desalination fuel cells, in particular to a multi-effect photosynthetic microbial fuel cell and its realization method. Background technique [0002] Microbial fuel cell (MFC) is a device that oxidizes organic matter by microorganisms and generates electricity. Its biggest advantage is that it can simultaneously obtain electrical energy while treating wastewater, thereby reducing the operating cost of wastewater treatment. For example, the patented high-efficiency microbial fuel cell (application number: 201180024710.2) uses extracellular electricity-producing bacteria (bacteria) as the anode, and the cathode is in contact with air. [0003] Although in the past few years, the power density of MFC has changed from the original 11Wm -3 increased to 4000Wm -3 , but because of its low output power, it is difficult to recycle the recovered electric energy, which limits its practical application. ...

AI Technical Summary

Problems solved by technology

Although this method can overcome the shortcomings of MDC such as pH imbalance and in-situ continuous treatment, but due to the limitation of the distance between the two capacitor plates, the volume of the desalination chamber is limited, which reduces the treatment capacity of the salt solution and the desalination rate. Low, poor salt removal rate
