Magnetic seed type sewage treatment method and device

Abstract

The invention relates to a magnetic seed type sewage treatment method and a device. The device is characterized by comprising a sewage interfusion flocculant, a coagulant aid, a magnetic seed part, a sewage treatment part and a magnetic seed / pollutant separation part, wherein the sewage treatment part is connected with the sewage delivery ports of the sewage interfusion flocculant, the coagulant aid and the magnetic seed part, the magnetic seed / pollutant separation part is connected with an outlet of a colloid shape flocculating pollutant discharged and separated by the sewage treatment part,the sewage treatment part comprises a sewage containing cavity, a permanent magnet plate, a power device, dynamic scraping plates and a pollutant scraping propulsion device, the permanent magnet plate is arranged in the sewage containing cavity and is provided with a non-magnetic plate, the power device drives the permanent magnet plate with the non-magnetic plate to move up and down, the dynamicscraping plates are positioned above the sewage containing cavity and are arranged at the two side faces of the permanent magnet plate with the non-magnetic plate, and the pollutant scraping propulsion device is positioned above the dynamic scraping plates. Compared with the prior art, the invention has the advantages of separating clear water and dirt effectively and quickly, recovering magneticseeds and adding the recovered magnetic seeds into a sewage treatment system newly.

Description

Technical field: [0001] The invention relates to a water treatment method and device. Background technique: [0002] Pollutants in sewage generally exist in the form of colloids. The latest and more effective way to remove the above-mentioned colloidal flocculation pollutants in sewage is to add flocculants, coagulants and magnetic species (iron compounds, such as ferromagnetic powder such as ferromagnetic powder), flocculants and coagulants are pollutants in sewage in the form of flocculated pollutants, and then the flocculated pollutants mixed with magnetic species are magnetically sucked The pollutants are adsorbed, so that these flocculent pollutants are separated from the water, and the sewage becomes clean water again. The problem to be solved by adopting the above method is how to recover the magnetic seeds effectively and quickly and put the recovered magnetic seeds back into the sewage treatment system. The existing technology has not yet solved the above problems....
