Magnetic photocatalysis resource recycling type artificial adsorption floating bed

Abstract

The invention provides a magnetic photocatalysis resource recycling type artificial adsorption floating bed which is formed by stacking a photocatalysis layer, a magnetic nitrogen removal adsorption layer and a magnetic phosphorus removal adsorption layer sequentially from top to bottom, wherein the photocatalysis layer suspends over the water surface; and the magnetic nitrogen removal adsorption layer and the magnetic phosphorus removal adsorption layer are immerged in the water surface. The magnetic photocatalysis resource recycling type artificial adsorption floating bed provided by the invention can be thrown for use simply and does not need artificial maintenance at ordinary times; the secondary function recovery can be realized through simple water flushing and sunlight exposure and secondary spraying; and the waste matrix material such as sludge and straw is prepared by the technical means such as exposure and ultrasonic dispersion without addition of any chemical raw materials which can cause secondary pollution, and new environmental pollution is avoided. The magnetic photocatalysis resource recycling type artificial adsorption floating bed has the advantages that the investment cost is low, secondary pollution is avoided, the resource utilization and green recycling of the industrial and agricultural wastes are realized by consuming the sludge of river channels.

Description

technical field [0001] The invention relates to the field of environmental engineering sewage treatment, in particular to a magnetic photocatalytic resource recycling type artificial adsorption floating bed for micro-polluted water treatment and river water treatment, which is suitable for treating micro-polluted water, micro-polluted lake (river) water, and the like. Background technique [0002] In the past ten years, with the rapid development of my country's industrialization and urbanization, people's living standards have been improving day by day, but people's pollution of water environment in production and life is also increasing day by day. Pollutants in lakes, rivers and various water bodies continue to increase, especially in urban rivers and lakes, where nitrogen, phosphide and COD (chemical oxygen demand) exceed the standard. These pollutants are widely distributed in the water body, are difficult to degrade, lead to eutrophication of the water body, have a lon...

AI Technical Summary

Problems solved by technology

[0003] In water bodies such as river water, river course water, and lake water, the native nitrogen, phosphorus, and COD are different from general wastewater, and there are problems such as low content and refractory degradation. Moreover, there are differences between various treatment processes for conventional nitrogen and phosphorus removal. Mutual influence and restrictive factors, easy to form secondary pollution
