Disk Sewage Treatment Equipment Is Used for Sewage

The advanced magnetic separator utilizes the potent magnetic energy derived from the neodymium-iron-boron, a rare-earth permanent magnet. This design innovation employs a magnetic assembly of the rare-earth disk, creating a high-intensity magnetic field with a steep gradient in the working area. This design ensures that the ferromagnetic particles present in sewage, wastewater, or water feed, along with non-magnetic particle flocs, can overcome fluid resistance, gravitational pull, and other mechanical forces due to the magnetic field. These particles exhibit rapid directional motion towards the rare-earth magnetic disk and get attached to its surface, thereby facilitating the separation of suspended matter from wastewater. Subsequently, a magnetic separation device removes these adsorbed materials from the disk surface. They are then transferred into a sewage discharge channel and extracted via a pressure water or slag conveying system. This process enables effective purification and recycling of wastewater.

The advanced magnetic disk separation and purification system is comprised of a set of powerful rare-earth magnetic disk machinery designed for separating materials. As illustrated in the figure, wastewater passes through the flow channel between the magnetic disks. Magnetic suspended particles within the water are attracted to the disk surface by the magnetic field force, and subsequently separated from the water as the disks rotate. Once the disks reach the slag scraper, the sludge is discharged from the disk in the magnetic isolation area. The sludge is scraped into a discharge tank by the scraper. The collected sludge is directed into a magnetic separation drum, while clean water is extracted and exits through the designated water outlet, completing the purification process.

• A sewage pump    extracts water from the inlet, transporting it to a coagulation reaction tank. Here, the water is uniformly mixed with a magnetic substance of a specific concentration.

• Once combined with the magnetic substance, the water undergoes a reaction facilitated by a coagulant and a coagulant aid. This reaction causes the magnetic and non-magnetic suspended substances to unite, resulting in the formation of magnetic flocs.

• After the coagulation, the water containing the magnetic flocs flows into a super magnetic separation device. Here, a magnetic disk isolates and purifies the magnetic flocs from the rest of the water. This process enables the purification and separation of the magnetic flocs from the water, which can then be discharged or reused.

• The separated micro-magnetic flocs are further processed by a magnetic powder recovery device. This separates them from the non-magnetic sludge, enabling the magnetic substances to be recovered for reuse. The remaining sludge is moved into a concentration tank, where it undergoes treatment by a sludge dehydrator.
