Abstract

The invention relates to a water treatment method and system, and belongs to the technical field of environmental friendliness, and particularly relates to a sewage treatment method and system. The function of a high-gradient high-intensity magnetic field is utilized, a chain net structure is knitted from paramagnetic metal wires and placed in a specific position of the high-gradient high-intensity magnetic field, magnetic matter can be fast captured into three-dimensional meshes, and a magnetic adsorbing material can be returned to be reused through an injection system, a vacuum suction system and a cyclone solid-gas separation system of air compressing equipment. Meanwhile, an efficient adsorbing quantum carbon magnetic medium and a photoreaction medium with a catalytic reaction under the action of a wider-spectral-domain light source are provided, the photoreaction medium is in a particle form of a specific dimension, free settling separation is achieved through gravity, and a continuous high-speed work system is achieved.

Description

technical field [0001] The invention relates to a water treatment method and system, which belongs to the technical field of environmental protection, and in particular to a sewage treatment method and system. Background technique [0002] Heavy metals contained in wastewater are harmful to the environment and human health and last for a long time. A large amount of untreated waste is transferred to the soil system, and is collected and left in the soil environment under the action of natural factors. Soil pollution is mainly heavy metal pollution, among which cadmium, mercury, lead, and arsenic pollution are the most prominent. Chromium (Cr), arsenic (As), cadmium (Cd), zinc (Zn), nickel (Ni), etc. Heavy metal ions have the characteristics of refractory, irreversible, highly toxic, and easy to be enriched by organisms. A small amount can produce toxic effects and cause great harm. [0003] Traditional treatment methods for polluted water include: chemical precipitation, i...
