Abstract
The invention belongs to the field of seawater and brackish water desalination, microbial electrochemistry and microbial desalination fuel cells, and relates to a device and method for desalination of a cylindrical bio-cathode microbial desalination fuel cell. The device is composed of a resistor, an external circuit, an anolyte water outlet, a cathode and cathode bio-membrane, a catholyte, a cation exchange membrane, a desalination chamber, a catholyte inlet, a catholyte outlet, a cathode chamber top cover, an anion exchange membrane, an anode and anode bio-membrane, an anolyte, a cylindrical reactor shell, an anolyte inlet, an aeration head and a support. The method includes the first step of anaerobic acclimation of anode microorganisms, the second step of start of an MDC reactor, the third step of desalination operation of the MDC, and the fourth step of setting of the continuous flow operation condition. The device and method have the advantages that the device and method are suitable for being applied in practice; the maximum power density can reach 6.21 W/m<3>; in sequencing-batch operation, the desalination speed is 95.5 mg/h; the device is simple in structure, convenient to operate, low in cost and high in speed.
