The invention relates to a novel cathode structure aluminum electrolysis bath with longitudinal and transverse wave decreasing functions, which comprises an electrolysis bath shell, an electrolysis bath lining, a fire-resisting material, a cathode carbon block, a lining carbon brick, carbon tamping paste, fire-resisting concrete, and a cathode carbon bar. The cathode structure aluminum electrolysis bath is characterized in that the top surface of the cathode carbon block is provided with more than one raised structures each of which is connected with the cathode carbon block integrally, and the arranging mode of each raised structure is to be parallel to the axial direction of the cathode carbon block, vertical to the axial direction of the cathode block, or adopt a mixed mode of the two. The novel cathode structure aluminum electrolysis bath with the longitudinal and the transverse wave decreasing functions can slow down the flow speed of cathode aluminum fluid in the transverse direction and the longitudinal direction in the electrolysis bath and reduce the fluctuation height of the aluminum fluid surface in the transverse direction and the longitudinal direction, improve the stability of the aluminum fluid surface of aluminum, reduce the solution loss of the aluminum, reduce the electric energy consumption for aluminum electrolysis production, and prolong the service life of the novel cathode structure electrolysis bath.

The invention discloses a cell bottom structure of an electrolytic cell. The cell bottom structure comprises an electrolytic cell (1) and a cathode bus (2), wherein the bottom of the electrolytic cell (1) is provided with columnar cathode carbon blocks (3) which are perpendicular to the bottom of the electrolytic cell (1); and the lower ends of the columnar cathode carbon blocks (3) are connected with the cathode bus (2). In the cell bottom structure, the column cathode carbon blocks are vertically inserted in the bottom of the electrolytic cell, and the lower ends of the columnar cathode carbon blocks are connected with the cathode bus, so that current which is led in from anode carbon blocks is led out downwards from the columnar cathode carbon blocks through molten aluminum to reduce horizontal current in the molten aluminum; and a cathode which extends into the molten aluminum can effectively reduce fluctuation of the molten aluminum, so that a stable molten aluminum surface is achieved to reduce polar distance between the cathode and an anode and reduce the cell voltage to fulfill the aim of reducing power consumption.

The invention relates to an embedded bioelectricity synthesis system, which mainly comprises an anaerobic oxidation reactor, a bioelectric synthesis reactor, a culture solution circulation control system, a power supply and an external circuit; the bioelectric synthesis reactor is composed, from the inside to the outside, of a conductive reactor wall, a diaphragm and an anode, and the conductive reactor wall is also a cathode of the reactor; and the culture solution circulation control system is used for controlling and adjusting pH, temperature, CO2 concentration and the like of the culture solution.
