Embodiment 1

[0043] Example 1: A bioelectrochemical device with a cathode as the main structure for the synthesis of negative oxygen ions, hydrogen and methane

[0044] The cathode is used as the main structure to construct a bioelectrochemical device that can be used to synthesize negative oxygen ions, hydrogen and methane by extracting waste and waste water reduction energy. It includes an anode chamber 1 as a reactor, a conductive wall 2, a diaphragm 3, and an anode set. Drift net 4 and anode 5, external power supply 7 or load 6, and external circuit. The anode chamber 1 is provided with a water inlet 9, a water outlet 10 and a gas storage tank 8 connected to the gas outlet. The anode chamber 1 is sealed and used for anaerobic oxidation of waste and wastewater. The anode chamber is constructed of cylindrical stainless steel. The stainless steel wall serves as the cathode at the same time. The outside of the cathode is in contact with ambient air, and there is no independent cathode chambe...

Embodiment 2

[0045] Example 2: Independent cathode synthesis of negative oxygen ions, hydrogen and methane bioelectrochemical device construction

[0046] An electrochemical device for synthesizing negative oxygen ions, hydrogen and methane is constructed by using independent cathodes, including the anode chamber 1 as the reactor, the conductor wall 2, the diaphragm 3, the anode current collecting net 4 and the anode 5, and the external power source 7 or load 6 And the external circuit. The anode chamber 1 is provided with a water inlet 9, a water outlet 10 and a gas storage tank 8 connected to the gas outlet. (See the instructions attached figure 2 )

[0047] The anode chamber 1 is constructed and sealed with engineering plastics. The conductor wall 2 made of stainless steel tube, namely the cathode, forms an independent cathode chamber 11. The cathode is embedded in the anode chamber as an independent structure, the inside of the cathode is communicated with the circulating ambient air, ...

Embodiment 3

[0048] Example 3: Multiple devices sharing the cathode chamber are connected in series or in parallel to form an integrated device

[0049] As in the device described in Example 1, multiple (at least two) reactors constructed in series or in parallel, with stainless steel conductive walls can be used as independent anode chambers, sharing an open cathode chamber communicating with ambient air. (See the instructions attached image 3 )

Abstract

The invention relates to a bioelectrochemistry device and a bioelectrochemistry method for extracting reducing energy from waste and wastewater. The device comprises a positive electrode chamber serving as a reactor, a conductor wall, a membrane, a positive electrode, an external circuit and a load or an external power supply, wherein the conductor wall is a negative electrode of the reactor; the negative electrode serving as a reactor main body structure or an independent negative electrode is embedded into the positive electrode chamber. A plurality of the devices can be connected in parallel or in series to form an integrated device, so that the treatment capability is improved. The device can work under a biological fuel battery or biological electrolytic tank mode or alternately runs in the two modes; the pH value of the wastewater is controlled to be 4-9 in a working process.
