Embodiment 1

[0034] The method for the advanced treatment of organic matter in high-salt wastewater by electric cooperation with persulfate described in this embodiment comprises the following steps

[0035] (1) get 2-methoxyphenol concentration and be 300mL waste water (TDS value sees table 1 below) of 50mg / L in the reactor, add 0.3g sodium persulfate, make the sodium persulfate concentration in the solution be 1g / L ( Now the solution is neutral, the pH is about 7), and the initial pH of the waste water is adjusted to be 12 with NaOH;

[0036] (2) Insert a pair of carbon plate electrodes (5×2.5cm) into the reactor, keep the distance between the plates at 3cm, supply power from a constant voltage power supply, set the voltage at 2V, start the sulfate radical oxidation reaction, and the reaction time is 3h .

[0037] After the reaction is over, turn off the power and take out the electrode to terminate the reaction, and the solution in the reactor is the reaction effluent.

Embodiment 2

[0039] The method for the advanced treatment of organic matter in high-salt wastewater by electric cooperation with persulfate described in this embodiment comprises the following steps

[0040] (1) get 2-methoxyphenol concentration and be 300mL waste water (TDS value sees table 1 below) of 100mg / L in reactor, add 0.9g sodium persulfate, make sodium persulfate concentration be 3g / L in the solution, And adjust the initial pH of the wastewater to be 12;

[0041] (2) Insert a pair of carbon plate electrodes (5×2.5cm) into the reactor, keep the distance between the plates at 3cm, supply power from a constant voltage power supply, set the voltage at 2V, start the sulfate radical oxidation reaction, and the reaction time is 3h .

[0042] After the reaction is over, turn off the power and take out the electrode to terminate the reaction, and the solution in the reactor is the reaction effluent.

Embodiment 3

[0044] The method for the advanced treatment of organic matter in high-salt wastewater by electric cooperation with persulfate described in this embodiment comprises the following steps

[0045] (1) get 2-methoxyphenol concentration and be 300mL waste water (TDS value sees table 1 below) of 200mg / L in reactor, add 1.5g sodium persulfate, make sodium persulfate concentration be 5g / L in the solution, And adjust the initial pH of the wastewater to be 12;

[0046] (2) Insert a pair of carbon plate electrodes (5×2.5cm) into the reactor, keep the distance between the plates at 3cm, supply power from a constant voltage power supply, set the voltage at 2V, start the sulfate radical oxidation reaction, and the reaction time is 3h .

[0047] After the reaction is over, turn off the power and take out the electrode to terminate the reaction, and the solution in the reactor is the reaction effluent.

Abstract

The invention belongs to the technical field of advanced treatment of industrial waste water, and in particular relates to a method for advanced treatment of organic matter in high-salt waste water with electric cooperation with persulfate. The method for the advanced treatment of organic matter in high-salt wastewater by electric synergy with persulfate in the present invention combines the convenience of high salt content and low solution resistance of high-salt wastewater, and uses the direct and indirect oxidation of micro-electric field based on the principle of sulfate radical oxidation Function, on the basis of direct oxidation to remove organic matter, make persulfate generate more free radicals to act on the removal of organic matter under the action of micro-electric field, which can effectively remove refractory organic matter, and can achieve a removal rate of more than 90% of organic matter. Solve the problem of difficult deep removal of organic matter in high-salt and high-chlorine wastewater. Compared with the existing conventional persulfate advanced oxidation treatment method, there is no need to add any activator (such as iron), which effectively avoids the secondary pollution caused by the activator, and has the advantages of high efficiency and environmental protection.

Description

technical field [0001] The invention belongs to the technical field of advanced treatment of industrial waste water, and in particular relates to a method for advanced treatment of organic matter in high-salt waste water with electric cooperation with persulfate. Background technique [0002] In recent years, limited by the current level of social and economic development and technological development, many chemical industries have inevitably discharged a large amount of high-concentration saline wastewater containing organic pollutants. Most of these pollutants are harmful to the ecological environment and human body, and have already Water resources and water environment have caused impact and even harm. Due to the high salt content of such wastewater, it is difficult for conventional microorganisms to survive and grow, making it difficult to treat it with traditional biodegradation methods. Coal chemical industry is a process in which coal is used as raw material and con...
