Description

technical field

[0001] The invention relates to the technical field of magnetic separation of sewage, in particular to a rapid magnetic separation sewage treatment system. Background technique

[0002] With the development of my country's economy and the accelerated pace of industrialization, my country's industrialization has brought a lot of environmental pollution, especially the pollution of water resources. Originally, my country's water resources were not rich, and a large amount of pollution caused water shortages in some areas of our country, and the conservation of polluted water resources became an imminent problem.

[0003] Existing sewage treatment adopts the method of chemical reaction, but this method takes too long, the effect is too poor, and the occupied area is large, so it cannot really realize rapid sewage treatment.

[0004] Patent application number: 201010251476.4 discloses a new type of magnetic separation sewage treatment device, including a tank, t...

Examples

Embodiment

[0023] Such as figure 1 As shown, a rapid magnetic separation sewage treatment system includes a magnetic coagulation reaction device 1, a dosing device 2, a plate type magnetic separation device 3, a two-stage magnetic separation device 8 and sludge treatment equipment 9, and a magnetic coagulation reaction device 1 A dosing device 2 is provided above, and the magnetic coagulation reaction device 1 is used to form flocs from the pollutants in the sewage with magnetic powder as the core. The sewage outlet of the magnetic coagulation reaction device 1 and the sewage inlet of the plate type magnetic separation device 3 4 connected, the plate type magnetic separation device 3 includes a magnetic separation pool, a magnetic plate group 5, a slag scraper 6 and a mud collection bucket 7, the sewage inlet 4 of the plate type magnetic separation device 3 is located at the bottom of the magnetic separation pool, and the magnetic The plate group 5 is composed of several parallel magneti...
