High salinity wastewater electrolytic oxidation treatment device

Abstract

The invention discloses a high salinity wastewater electrolytic oxidation treatment device which is a radial electrode electrolysis reactor. The device consists of a water inlet pipe, an electrolysis column, electrode plates, a center support and a top cover; and the electrolysis device is cylindrical; the electrode plates are arranged radially; and the device is provided with a water charging and distributing device, a water discharging device and a sludge discharging device. All the parts of the device are movable, thus the parts can be assembled, disassembled, cleaned, maintained and changed conveniently; the technical problem that the device is easy to scale and corrode in the high salinity wastewater treatment can be solved; and the area of each electrode plate is large, the decolorization effect is good, the molecular structures of micromolecular organic materials in wastewater can be damaged and the biodegradability of wastewater can be increased. The device disclosed by the invention can well separate the three phases, namely water, gas and bubbles, and sludge; and the water-discharging effect can be ensured. In both continuous flow treatment and batch treatment, the inside of the device disclosed by the invention provides good hydrodynamic conditions, thus the reaction can be performed completely, the treatment efficiency is high, the electricity can be saved and the treatment cost can be reduced.

Description

technical field [0001] The invention belongs to a two-dimensional electrolytic oxidation reactor in the technical field of sewage treatment. Background technique [0002] Fermentation wastewater has high organic content, complex structure, and poor biodegradability. Electrolytic treatment can open the macromolecular structure of organic matter and improve biodegradability. Fermentation wastewater has high salinity and good conductivity, which is suitable for electrolytic treatment, but it is also easy to scale in the device and corrode the electrodes, which affects the use effect and service life of the electrolysis device. Therefore, the electrolysis device is required to be easy to disassemble, easy to clean and maintain, and easy to replace the electrodes. [0003] Commonly used concentric circle electrode reactors have small electrode area and poor electrolysis effect. The pole plates of the parallel-plate wastewater electrolysis device are often fixed with upper scre...

[0003] Commonly used concentric circle electrode reactors have small electrode area and poor electrolysis effect

The pole plates of the parallel plate wastewater electrolysis device are often fixed by upper screws, which are easy to rust and difficult to replace; the suspension type can be easily taken out, but the suspension parts affect the water intake and operation, and the treatment effect of the parallel plate type is relatively low

Electrolysis patent 200420045119.2 proposes a radiant electrolytic cell, the electrode plates are arranged radially, which can increase the electrode area and improve the treatment effect, but it can only be used for static treatment, and a pusher mixer is set in the middle, which greatly reduces the size of the electrolytic cell. The effective volume of electrolysis, the electrode plate is fixed by bolts, which is not convenient for the replacement of the electrode plate. It is mainly used to recover metals in wastewater, and is not suitable for the treatment of high-salt wastewater.
