Synchronous anti-corrosion and dephosphorization device and method used in integrated sewage treatment equipment

Abstract

The invention discloses a synchronous anti-corrosion and dephosphorization device used in integrated sewage treatment equipment, the synchronous anti-corrosion and dephosphorization device comprises an insulating shell and electrode plates, the insulating shell is provided with a water passing hole, the electrode plates comprise a cathode electrode plate and an anode electrode plate, and the anode electrode plate and the cathode electrode plate are externally connected with a power supply module through wires; the anode electrode plate is arranged in the insulating shell and is mounted on the inner wall of one side of the insulating shell; the cathode electrode plate penetrates through the side face, opposite to or adjacent to the side where the anode electrode plate is installed, of the insulating shell to be installed, one part of the cathode electrode plate is located in the insulating shell and corresponds to the anode electrode plate, and the other part of the cathode electrode plate is located outside the insulating shell and used for being connected with the conductive inner wall of the integrated sewage treatment equipment. The synchronous anti-corrosion and dephosphorization device for the integrated sewage treatment equipment can be inserted into the integrated equipment at will for use, it can be guaranteed that the material of a shell of the integrated equipment is not corroded forever in the use process, and total phosphorus in wastewater can also be efficiently removed.

Description

technical field [0001] The application relates to the field of water treatment, in particular to a device and method for synchronous anti-corrosion and phosphorus removal of integrated sewage treatment equipment. Background technique [0002] Integrated sewage treatment equipment is a common equipment for decentralized sewage treatment at present. Generally, the materials of integrated equipment include carbon steel, stainless steel, galvanized sheet and other materials. The protective layer of these materials is easy to break and fall off, so that the main material is still prone to corrosion in the water environment, and the service life is often not more than 5 years. [0003] In addition, the process adopted by the integrated sewage treatment equipment is mainly biochemical process, such as AO process, MBR process, A 2 O process, SBR process, etc. These processes have good removal performance for conventional pollutants such as COD, ammonia nitrogen, and total nitrogen....

AI Technical Summary

Problems solved by technology

However, with the extensive use of electrolytic phosphorus removal devices, the electrode sheets are easily passivated, and problems such as scum generation during the electrolysis process have gradually emerged.
