Abstract

The invention discloses a wastewater treating device based on internal circulation and repeated use of a nanometer material. The wastewater treating device comprises a nanometer material and oxidant releasing system, a stirring reaction system, a precipitation separation drainage system and a permanent magnetic adsorption system. According to the wastewater treating device disclosed by the invention, based on extremely strong polymerization of the nanometer material, reducing substances such as organic compounds in wastewater are integrated with continuously added oxidant to carry out reaction, and harmful impurities such as the organic compounds in the wastewater are eliminated. According to the wastewater treating device, in the initial stage that the wastewater treating device is put into use, the enough quantity of the nanometer material is injected into the wastewater treating device along with the oxidant, the oxidant and the organic compounds are polymerized together by virtue of the nanometer material to form a large proportion of particles, the organic compounds are decomposed into CO2 and water under the action of the oxidant, and the wastewater is purified; after a round of work, nano-particles continuously search a new target and are repeatedly used. As the environment of repeated use of the nanometer material is created, the wastewater treating device has the characteristics of low cost, high efficiency, reliability in running, capability of realizing unmanned on duty for a long time and the like.

Description

technical field [0001] The invention relates to a sewage treatment device which utilizes the internal circulation and repeated use of nanometer materials, in particular to a sewage treatment device used for COD treatment in industrial waste water. Background technique [0002] The adsorption and desorption of COD in sewage using nano-magnetic particles is a new sewage treatment technology. Due to the high specific surface area of ​​nano-materials, it has a strong adsorption capacity for COD substances, and the magnetic properties of nanoparticles can make it It is adsorbed and separated in an external magnetic field and regenerated. Therefore, the use of this technology for COD treatment avoids many shortcomings of traditional biological methods, and has attracted widespread attention in the water treatment industry in recent years. Japanese patent PCT / JP2004 / 0115862004.8.5 Chinese application number CN1697784A discloses a device using magnetic separation technology to proce...
