[0019] Specific implementation mode one: combine figure 1 To illustrate this embodiment, the electricity generation and desalination device based on electronic control in this embodiment includes an anode chamber 1, an anode carbon brush 2, an anion exchange membrane 3, a desalination chamber 4, a cation exchange membrane 5, a cathode carbon brush 6, a cathode chamber 7, Reference electrode 8, external resistance 9 and aeration device 16; the desalination chamber 4 is arranged between the anode chamber 1 and the cathode chamber 7, and the left side of the desalination chamber 4 and the right side of the anode chamber 1 pass through an anion exchange membrane 3, the right side of the desalination chamber 4 is separated from the left side of the cathode chamber 7 by a cation exchange membrane 5; A water outlet 10, a first water inlet 11 is arranged on the lower left side of the anode chamber 1, and the reference electrode 8 penetrates through the upper wall of the anode chamber ...

specific Embodiment approach 2

[0020] Embodiment 2: This embodiment differs from Embodiment 1 in that the volumes of the anode chamber 1 and the cathode chamber 7 are the same. Other steps and parameters are the same as those in the first embodiment.

specific Embodiment approach 3

[0021] Specific Embodiment Three: The method of using the electronic regulation-based power generation desalination device of the present embodiment to treat sulfur-containing ammonium refinery wastewater is specifically carried out according to the following steps:

[0022] 1. Inject activated sludge capable of degrading refining wastewater into the anode chamber 1 and cathode chamber 7, respectively, and then add sulfur-containing ammonium refinery wastewater to the anode chamber 1 and cathode chamber 7 respectively until the anode chamber 1 is sealed. 18h-26h, the cathode chamber 7 is continuously aerated by the aeration device 16 for 18h-26h, and then the sulfur-containing ammonium refining waste water in the anode chamber 1 and cathode chamber 7 is discharged;

[0023] 2. Use an external resistor 9 to connect the anode carbon brush 2 and the cathode carbon brush 6, and then add PBS buffer solution to the anode chamber 1 and the cathode chamber 7 to a concentration of 18ppm...

Abstract

The invention provides an electrogenic desalting device based on electronic regulation and control and a method for treating ammonium sulfate-containing ptetrochemical wastewater by using the device, and relates to the field of wastewater treatment and resource cyclic utilization, in particular to the electrogenic desalting device and the method for treating ammonium sulfate-containing ptetrochemical wastewater by using the device. The device and the method aim at solving the problems that in the prior art, the treatment difficulty of industrial wastewater is high; the biological chemical treatment is difficult; energy sources in the industrial wastewater are wasted. The electrogenic desalting device comprises an anode chamber, an anode carbon brush, a negative ion exchange film, a desalting chamber, a positive ion exchange film, a cathode carbon brush, a cathode chamber, a reference electrode, an outer resistor and an aeration device. The method for treating wastewater by the electrogenic desalting device is concretely performed according to the following steps of firstly performing domestication on active sludge with the ptetrochemical wastewater degradation capability so that all active sludge can become electrogenic bacteria; then, treating the ammonium sulfate-containing ptetrochemical wastewater in the anode chamber; next, treating the ammonium sulfate-containing ptetrochemical wastewater in the cathode chamber; finally, performing desalting through the desalting chamber. The ammonium sulfate-containing ptetrochemical wastewater is subjected to desalting and standard-reaching treatment.

Description

technical field [0001] The invention relates to the fields of wastewater treatment and resource recycling, in particular to an electricity generation desalination device and a method for treating ammonium sulfate refinery wastewater by using the device. Background technique [0002] Environmental issues and energy issues restrict the development of human society. Due to the continuous development of my country's industry, resulting in a sharp rise in industrial water consumption, which undoubtedly aggravated the crisis of water shortages. A large amount of chemical wastewater produced in the production of chemical industry contains hydrocarbons and other refractory substances. If it cannot be disposed of properly, it will inevitably cause pollution to the receiving environment, threaten the safety of the ecological environment, and endanger the health of humans and other organisms. Therefore, chemical industry The treatment of wastewater has always been a problem that plagu...
