Arsenic-containing wastewater treatment device

Abstract

The invention discloses an arsenic-containing wastewater treatment device which comprises an electrolytic bath, an electrolysis device is arranged in the middle of the electrolytic bath, an insulating base is arranged between the electrolysis device and the electrolytic bath, the electrolysis device comprises an electrolysis cathode, an electrolysis anode is arranged in the electrolysis cathode, and an air phase is arranged between the electrolysis cathode and the electrolysis anode. An air diffusion cathode is arranged on the side, close to the electrolytic anode, of the electrolytic cathode, a plurality of diffusion channels are formed in the two sides of the electrolytic cathode, the electrolytic anode is connected with the solar storage battery through an electrified arm, ultrasonic probes are arranged between the electrolytic cathode and the electrolytic anode and in the electrolytic bath, and a water inlet and a water outlet are formed in the two sides of the electrolytic bath respectively. A settling pond is arranged at the bottom of the electrolytic bath; and an aerator is also arranged in the electrolytic bath. The arsenic-containing wastewater is treated in a ferroelectric coagulation arsenic precipitation mode, and the problems that in the prior art, arsenic-containing substances cannot be effectively removed, a flocculating agent needs to be added, the treatment cost is high and the like are effectively solved.

Description

technical field [0001] The invention belongs to the technical field of arsenic-containing wastewater treatment equipment, and in particular relates to an arsenic-containing wastewater treatment device. Background technique [0002] With the growing industrial production, the discharge of industrial arsenic-containing wastewater is increasing. If the wastewater is discharged directly without treatment, it will reduce the biochemical oxygen demand and cause serious pollution of the surrounding soil. Arsenic is a toxic Substances that enter the human body through food and water can cause harm to humans. Through the treatment of arsenic in industrial wastewater, the water pollution in our country can be alleviated and the economic losses caused by water pollution can be reduced. Therefore, the treatment of arsenic-containing wastewater has broad development prospects in the future development of our country. However, the existing arsenic-containing wastewater treatment device h...
