Embodiment Construction

[0019] For ease of understanding, combined here figure 1 , the specific embodiments of the present invention are further described as follows:

[0020] As shown in the accompanying drawings, the present invention is a treatment method and device for wastewater containing heavy metal ions. It is characterized in that a laser emitter is used to generate laser light to irradiate the surface of the silver particle array installed in the cylindrical cone-shaped container, so that the silver particle A local electric field is generated near the array, and when wastewater containing heavy metal ions flows through the silver particle array, the heavy metal ions are subjected to the action of the electric field and are adsorbed on the surface of the silver particles, while the silver particles have a strong bactericidal effect.

[0021] Further, the cylindrical-conical container is made of iron metal, the upper part is cylindrical, and the lower part is conical. The waste water inlet i...

Abstract

The invention discloses a method and a device for treating wastewater containing heavy metal ions. The method and the device are characterized in that laser generated by a laser emitter irradiates thesurface of a silver particle array mounted in a cylindrical-conical container, a local electric field is generated near the silver particle array, and the heavy metal ions are adsorbed on surfaces ofsilver particles under the action of the electric field when the wastewater containing the heavy metal ions flows near the silver particle array. In the treatment process of the wastewater containingthe heavy metal ions, other substances are not added, no by-products are generated, the influence of water quality is avoided, various heavy metal ions in the wastewater can be removed, energy consumption is low, and strong bactericidal effects are achieved.

Description

technical field [0001] The invention relates to a treatment method and device for waste water containing heavy metal ions, in particular to a treatment method and device for waste water containing heavy metal ions, and belongs to the technical field of environmental protection. Background technique [0002] With the development of my country's industry, more and more waste water containing heavy metal ions is produced, such as mine smelting, chemical industry, electronics, machinery manufacturing, instrumentation, etc., all of which contain a large amount of heavy metal ions in the waste water, which is harmful to the environment and human beings. have caused great harm. How to effectively process and recover these heavy metal ions has become a hot topic in environmental protection today. [0003] Heavy metals usually refer to density greater than 4.5g / cm 3 metals, including gold, silver, copper, iron, lead, etc. Heavy metals can strongly interact with proteins and enzymes...
