specific Embodiment approach 1

[0017] Specific implementation mode one: combine figure 1 As shown, this embodiment is used for the continuous flow three-stage bioelectricity desalination device for the treatment of acetonitrile-containing refinery wastewater, which includes an anode chamber 1, an anode carbon brush 2, an anion exchange membrane 3, a desalination chamber 4, a cation exchange membrane 5, Cathode carbon brush 6, cathode chamber 7, reference electrode 8, aeration device 9, facultative chamber 10, resistance 11, water pump 12; A desalination chamber 4 is set between the anode chamber 1 and the cathode chamber 7; the anode chamber Anion exchange membrane 3 is set between 1 and desalination chamber 4, and cation exchange membrane 5 is set between desalination chamber 4 and cathode chamber 7; anode carbon brush 2 and reference electrode 8 are arranged in anode chamber 1, and a bottom of anode chamber 1 is provided with a The water outlet; the upper part of the desalination chamber 4 is provided wit...

specific Embodiment approach 2

[0020] Specific embodiment two: the application method of this embodiment for the continuous flow three-stage bioelectricity desalination device for the treatment of acetonitrile-containing refinery wastewater is carried out according to the following steps:

[0021] 1. Cultivation stage: turn off the water pump 12, inoculate the activated sludge with refining wastewater degradation ability in the anode carbon brush 2, cathode carbon brush 6 and facultative chamber 10 respectively, and then inject the activated sludge into the anode chamber 1, cathode chamber 7 and facultative chamber respectively. The chamber 10 is filled with refining waste water containing acetonitrile, the anode chamber 1 is sealed for 24 hours, the cathode chamber 7 is continuously aerated for 24 hours through the aeration device 9, the facultative chamber 10 stays still for 24 hours, and then drained separately;

[0022] 2. Acclimatization stage: connect the anode carbon brush 2 and cathode carbon brush 6...

specific Embodiment approach 3

[0029] Embodiment 3: This embodiment differs from Embodiment 2 in that the activated sludge capable of degrading refinery wastewater in step 1 comes from the activated sludge in the secondary settling tank of an urban domestic sewage treatment plant. Other steps and parameters are the same as in the second embodiment.

Abstract

The invention relates to a continuous flow three-section biological electrogenesis desalination device for treating acetonitrile-containing refining waste water and an application method thereof, belonging to the field of the refining waste water treatment, and aiming at solving the problem that the resource is wasted in the existing chemical industrial waste water treatment process. The continuous flow three-section biological electrogenesis desalination device comprises an anode chamber, an anode carbon brush, an anion exchange membrane, a desalination chamber, a cation exchange membrane, a cathode carbon brush, a cathode chamber, a reference electrode, an aeration device, a facultative chamber, a resistor and a water pump. The application method comprises the following steps: generating an anaerobic electrogenesis biological membrane, an aerobic electrogenesis biological membrane and facultative anaerobic active sludge by virtue of culturing and acclimatization; and facilitating the flow of the water to be treated in various treatment chambers in a gravity flow manner, thereby obtaining stable electric energy output. A continuous running way is adopted to treat the waste water so as to degrade the organic matters and efficiently remove the salt, so that the treatment to toxic and harmful substances is realized, the stable electric energy output can be obtained, no additional energy input or high penetration pressure is needed in the continuous flow three-section biological electrogenesis running process, and the application prospect is good.

Description

technical field [0001] The invention belongs to the field of refining and chemical wastewater treatment, and in particular relates to an electricity-producing desalination device and an application method thereof. Background technique [0002] Environmental issues and energy issues restrict the development of human society. Due to the continuous development of industry, the consumption of industrial water has increased sharply, which has undoubtedly aggravated the crisis of water shortage. 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 plagues industrial development and human life. At the ...
