Problems solved by technology

[0003] On the one hand, high-salt organic wastewater will not only cause corrosion of buildings and equipment, but also cause anoxic and anaerobic water bodies due to biodegradation, resulting in the death of aquatic organisms, thus causing water quality problems and environmental pollution
On the other hand, in the process of wastewater treatment, higher salinity can inhibit the growth of microorganisms, which is not conducive to the treatment of wastewater by biological methods, and increases the difficulty of wastewater treatment.

Embodiment 1

[0028] The specific preparation process of the porous carbon material electrode is as follows: first prepare RF sol (resorcinol-formaldehyde sol), dissolve 1g resorcinol and 0.018g sodium hydroxide in 20-30ml ethanol, then slowly add 2ml formaldehyde solution , magnetically stirred at room temperature for 50 min to obtain a light yellow sol. Then dissolve 0.50g of F127 in 20ml of ethanol solution, slowly add the above solution dropwise, and keep stirring for 50min, then introduce the solution into a watch glass at a temperature of 30°C for self-assembly, and then place it in an oven at 100°C to solidify the structure .

[0029] Mix the ordered mesoporous carbon material prepared above with the conductive agent and the adhesive in a mass ratio of 8:1:1, roll it into a thin sheet with a double-roller machine, and use a mold to press it to about 100×20×1 mm. The above film was shredded and heated in a tube furnace. The atmosphere was nitrogen during high-temperature carbonizatio...

Abstract

The invention discloses a preparation method of a mesoporous carbon electrode. RF sol is used as a carbon source, a triblock copolymer F127 is used as a template agent, an F127-RF composite material is prepared through a solvent evaporation induced self-assembly soft template method under an alkaline condition, a highly ordered mesoporous carbon material with a high specific surface area is directly obtained through high-temperature carbonization treatment in an inert atmosphere, the mesoporous carbon material is uniformly mixed with a conductive agent and an adhesive according to a mass ratioof 8:1:1, a double-roller machine is utilized for rolling into a sheet, and high-temperature carbonization treatment is performed to directly obtain the highly ordered mesoporous carbon material with the high specific surface area. The mesoporous carbon material electrode synthesized according to the preparation method has a very remarkable electro-adsorption desalting effect on inorganic salt ions in high-salt-content wastewater, and mesoporous carbon has a relatively large specific surface area and pore volume, so that the adsorption capacity and the desalting rate of the ions are increased; the high-salt-content organic wastewater treatment equipment based on the mesoporous carbon electrode can realize electro-adsorption desalting of high-salt-content organic wastewater.

Description

technical field [0001] The invention belongs to the technical field of wastewater treatment, and in particular relates to a mesoporous carbon electrode used for treating high-salt organic wastewater and organic wastewater treatment equipment based on the electrode. Background technique [0002] High-salt organic wastewater refers to wastewater containing high concentrations of soluble inorganic salts and toxic and refractory organic matter. The main sources are domestic sewage, industrial sewage produced by industrial activities such as printing, papermaking, and electroplating, and sewage produced by large marine ships. . [0003] On the one hand, high-salt organic wastewater will not only cause corrosion of buildings and equipment, but also cause anoxic and anaerobic water bodies due to biodegradation, resulting in the death of aquatic organisms, thereby causing water quality problems and environmental pollution. On the other hand, in the wastewater treatment process, hig...
