Magnetization sedimentation tank for sewage purification and purification method

Abstract

The invention discloses a magnetization sedimentation tank for sewage purification. The magnetization sedimentation tank comprises a closed box body (1); a dosing mixing bin (2) is arranged at the lower part of the box body (1); the dosing mixing bin (2) is connected with an electromagnetic reaction bin (4); an electromagnetic reaction bin (5) is connected with a chemical reaction bin (7); the lower part of the chemical reaction bin (7) is connected with a sewage distributor (8) and a sewage diverter (9); an inverted conical sludge settling chamber (10) is arranged below the sewage diverter (9); the lower end of a sludge outlet pipe (11) is arranged at the bottom of the sludge settling chamber (10), and the upper end of the sludge outlet pipe (11) is connected with a sludge discharge port(12) in the upper part of the box body (1); the side wall of the box body (1) is connected with a circle of overflow groove (13); the overflow groove (13) is connected with a clear water port (14) onthe side wall of the box body (1). The magnetization sedimentation tank has the advantages of integrating multiple functions, saving land occupied area and investment cost, and being simple, efficient, higher in settling speed, better in treatment effect and smoother in sludge discharge.

Description

technical field [0001] The invention relates to the technical field of sewage purification equipment, in particular to a magnetized sedimentation tank for sewage purification and a purification method thereof. Background technique [0002] At present, sewage purification treatment devices generally include stirring tanks, sedimentation tanks, hydrolytic acidification tanks, aerobic tanks, and air flotation machines, which cover a large area and need to undergo sterilization, oxidation and reduction, decolorization, COD reduction, and air flotation in sequence. Solid-liquid separation and other processes can complete the final purification treatment, which is cumbersome and complicated, which increases investment costs and operating costs. [0003] At the same time, the sewage settling speed in the existing sewage purification device is slow, the treatment effect is relatively poor, the separation of mud and water is not complete, and the water content of the mud is high, whi...
