Embodiment 1

[0079] Sewage purification process:

[0080] The sewage entering the sump enters the strong magnetic catalysis process after pressurization, the sewage from the strong magnetic catalysis process enters the micron aeration and dissolved oxygen process, and the sewage from the micron aeration and dissolved oxygen process enters the second sewage strong magnetic catalysis process, the sewage from the second sewage strong magnetic catalysis process enters the metal recovery process in the magnetoelectrolysis sewage, and the sewage from the metal recovery process in the magnetoelectrolysis sewage enters the magnetoelectric primary filtration process; the sewage from the magnetoelectric primary filtration process Water enters the magnetoelectric PH adjustment process, the water from the magnetoelectric PH adjustment process enters the strong magnetic reduction process, the water from the strong magnetic reduction process enters the micro-electrolytic fine filtration process, and the ...

Embodiment 2

[0096] In this embodiment, since the water body does not contain metal components that need to be recovered, it does not pass through the magnetoelectrolytic metal recovery device, but directly enters the magnetoelectric primary filtration system. All the other are the same as embodiment 1

Embodiment 3

[0098] In this embodiment, because the acidity and alkalinity are normal, the magnetoelectric pH adjustment device is not carried out and directly enters the strong magnetic reduction device. All the other are the same as embodiment 1

Abstract

The invention relates to a magnetoelectric nanofiltration sewage purification system and a magnetoelectric nanofiltration sewage purification process. In the invention, various advanced magnetic techniques are adopted, advanced physical filtration techniques such as a steel fiber microfiltration technique, a carbon fiber nanofiltration technique, a membrane filtration technique and the like are combined, and parts such as a micron dissolved oxygen tower, a ferromagnetic catalysis device, a ferromagnetic reduction device, a magnetoelectric primary filtration device, a pressurizing device, a microelectrolysis fine filtration device, a mineralization device, a sewage treatment device, a magnetoelectric metal recovery device, a pipeline, a valve control device, a magnetoelectric PH regulation device, a circuit system, an automatic programmed control system, an automatic backwashing device and the like are adopted. Consumable materials such as chemical or biological preparations and the like are not required to be added, secondary pollution is avoided, the system is operated in a totally closed mode, has low energy consumption, is basically not required to be maintained and can be operated for a long time, and the system and the process are ideal updated products of the conventional sewage purification and drinking water optimization equipment and the conventional sewage purification and drinking water optimization technology.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a magnetoelectric nanofiltration sewage treatment process and device. Background technique [0002] Water is the source of life. At present, water resources are frequently in emergency around the world. my country is one of the countries where water resources are scarce. It is the responsibility of Chinese people to make full use of existing water resources and do a good job in the recycling and utilization of water resources. However, the current sewage purification equipment and processes in operation generally have the disadvantages of large energy consumption, large investment, large floor area, high operating cost, difficult maintenance, low work efficiency, poor treatment effect, and small treatment range. It does not have wide applicability, does not have the advantages of rapid promotion, and does not have the advantages of low consumption and high production p...
