Abstract

The invention relates to the field of wastewater treatment and resource cyclic utilization, in particular to a device for treating acrylonitrile-containing oil refinery wastewater through power generation desalination based on electronic regulation and control and an application method of the device. The device and the application method aim at solving the problems that in the prior art, the difficulty of industrial wastewater treatment is large, biochemical treatment is difficult, and energy in industrial wastewater is wasted. The 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 external resistor and an aeration device. The method includes the steps that firstly, activated sludge is acclimatized; secondly, the wastewater is treated in the anode chamber; thirdly, the wastewater is treated in the cathode chamber; fourthly, desalination treatment is carried out. The device and the application method are used for treating the acrylonitrile-containing oil refinery wastewater and desalinating the wastewater.

Description

technical field [0001] The invention relates to the fields of waste water treatment and resource recycling, in particular to an electronic control-based device for generating electricity and desalting treatment of refinery waste water containing acrylonitrile and an application method of 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 ...
