Problems solved by technology

[0004] In the existing disk-type magnetic separators, the disks always have the following problems in the treatment of wastewater: 1. Some disks are thick discs cast as a whole, which are heavy and affect the stiffness and running stability of the shaft; and in practical applications, the disks The structural parameters are not reasonable enough, which affects the full performance of the disk
3. The structure of the disk group in the prior art does not match the disk and the treated water quality, which cannot give full play to the performance of the disk and cannot fully meet the wastewater treatment requirements

Embodiment 1

[0038] Treat rolling waste water 1500m with the technical scheme described in claim 10 of the present invention 3 / h, the concentration of suspended solids in the inlet is 350mg / L, the oil content is 40mg / L, the suspended solids content in the effluent is less than 20mg / L, and the oil content is less than 5mg / L.

[0039] Show in the experiment by the present invention, after the disk thickness is greater than 30mm, will increase the single weight of disk, thereby increase the winding degree of disk machine shaft, produce peristalsis during operation, affect the quantity of disk installed on the shaft, restrict the amount of wastewater treatment water, can not reach The present invention can treat 1500m of water by single machine 3 / h request. When the disk is assembled on the shaft, if the screw nut is positioned, the disks will stick to each other, and the parallelism of the disk cannot be effectively controlled, which will affect the uniformity of the water flow in the flow ...

Embodiment 2

[0041] The domestic sewage is treated with the technical scheme described in claim 10 of the present invention, adding magnetic seeds, and undergoing magnetic flocculation reaction. Water intake 10000m 3 / d, when the inlet suspended matter concentration is 340mg / L, COD is 235mg / L, and TP is 3.0mg / L; the effluent suspended matter content is less than 20mg / L, COD is less than 120mg / L, and TP content is less than 0.1mg / L.

The invention belongs to the field of sewage treatments, and particularly relates to magnetic disk wastewater purification equipment, which comprises a host machine, a transmission mechanism, a residue scraping mechanism, a residue discharge mechanism and a water inlet and drainage mechanism, wherein the host machine comprises a disk holder, a magnet and an inner radial plate, the disk holder is fixed on a main shaft in the center through the inner radial plate, a magnetic disk is divided into 12-30 sectors through the disk holder, the magnet is distributed in the sectors, and the host machine is an annular magnetic disk adopting an outer ring with a diameter of 500-2000 mm as a basis. The magnetic disk wastewater purification equipment has characteristics of reasonable structure, reliable operation, high efficiency, large wastewater treatment capacity, and good effect.

Description

technical field [0001] The invention belongs to the field of sewage treatment, in particular to a disk wastewater purification device. Background technique [0002] Magnetic separation is a technology that achieves material separation through the magnetic field attraction provided by a magnet. It belongs to the physical separation method and was developed in the United States in the early 1970s. It can quickly separate magnetic impurities in a mixture. Magnetic separation uses the magnetism of impurity particles in wastewater to separate. For non-magnetic or weakly magnetic particles in water, magnetic seeding technology can make them magnetic. With the help of the external magnetic field, the magnetic suspended solids in the wastewater are separated, so as to achieve the purpose of purifying the water. Compared with conventional methods such as sedimentation and filtration, the magnetic separation method has a series of advantages such as large processing capacity, high ef...
