The invention relates to a continuous
wastewater treatment device utilizing membrane
capacitive deionization. An upper cover plate and a lower cover plate are coaxially installed at the upper end and the lower end of a cylindrical shell, a water inlet
nozzle and a water outlet
nozzle which are communicated with the interior of the shell are respectively formed in the axis part of the upper cover plate and the axis part of the lower cover plate, a water collecting plate is coaxially installed on the upper cover plate in the shell, conducting rods are uniformly and axially distributed on the periphery of the shell at intervals, a lower
distribution board and an upper
distribution board are coaxially installed in the shell between the water collecting plate and a water distributing plate and are of a pair of
metal boards, and a plurality of groups of
processing module components are coaxially installed between the two distribution boards, wherein each group of
processing module component comprises an upper current collecting plate, a membrane carbon positive
electrode, a diaphragm, a membrane carbon negative
electrode and a lower current collecting plate. According to the continuous
wastewater treatment device, the membrane
electrode is integral and is prepared by a carbon electrode and an
ion membrane through spraying a cation exchange
coating on a
cathode and spraying an anion exchange
coating on an
anode, the thickness of the
ion exchange layer is less than 10mu, and the membrane electrode has small resistance and large
capacitance compared with those of a membrane electrode on which an
ion membrane is directly added.
