Seawater purifying and desalting treatment device and application

Abstract

The invention discloses a seawater purifying and desalting treatment device and application, and provides application of a MoO3-x nano material to seawater purifying and desalting treatment, wherein xis greater than zero and less than 1; and the invention further provides a seawater purifying and desalting treatment device which is made of the MoO3-x nano material. The invention aims to provide amaterial which can simultaneously achieve seawater purifying and desalting and design an apparatus capable of effectively collecting fresh water. By conditioning the concentration of oxygen vacancy in MoO3-x and analyzing the influence of the concentration of oxygen vacancy on the SPR (surface plasma resonance) effect, and utilizing the SPR effect to improve the photocatalysis and optical heat efficiency, the purposes of efficient achievement of purifying and desalting are realized simultaneously. The seawater purifying and desalting device provided by the invention is easy and practical, thetwo-step operation is completed by utilizing one material, the cost is lowered, the treatment procedure is simplified, and meanwhile, the photocatalytic degradation rate is high, and the optical heatperformance is good.

Description

technical field [0001] The invention relates to the technical field of seawater treatment, in particular to a seawater purification and desalination treatment device and its application. Background technique [0002] With the continuous development of society, the environmental pollution problem has become an important factor restricting development. Among them, the shortage of water resources caused by water pollution has made people pay more attention to the control of water pollution. Seawater purification and desalination, as an efficient method for obtaining freshwater resources, has attracted widespread attention. [0003] However, the current traditional seawater desalination methods, such as multi-effect distillation, osmotic membrane, and multi-stage flash evaporation, all have problems such as bulky, high energy consumption, large carbon emissions, and low desalination efficiency. Seawater desalination technology using solar photodistillation is low-carbon and en...
