Abstract

The invention relates to the technical field of solar light-heat conversion evaporation sewage purification and treatment, in particular to a portable solar light-heat conversion water treatment and purification device. By means of a solar collecting lens, the utilization rate of incident sunlight is effectively increased, and the heat evaporation speed of water is improved; by means of a porous filter membrane, large-particle pollutants are primarily filtered out from to-be-processed water; by means of a semiconductor nanometer material as the light-heat conversion carrier, on one hand, the light-heat conversion efficiency is improved and water evaporation is accelerated, and on the other hand, organic pollutants in water can be effectively removed due to the photocatalytic effect of thesemiconductor material. In addition, considering the application in weak-light areas and at nights, the electric heating auxiliary evaporation technology is adopted. Through the treatment of the device, most of impurities in original water can be removed, and the finally-obtained water quality can reach the level of deionized water. The survival water utilization problem in water source pollutionlands, sea island army service stations and other freshwater shortage environments is effectively solved.

Description

technical field [0001] The invention relates to the technical field of solar photothermal conversion evaporation sewage purification treatment, in particular to a portable solar photothermal conversion water treatment and purification device. Background technique [0002] Population, resources and environment are three major development issues facing the world today. Among resource issues, water resources are one of the most indispensable and irreplaceable resources for human beings. Water resources issues have become Today, it is one of the most important problems that the whole world pays close attention to and urgently needs to find a way to solve. The fresh water resources that humans can really use are part of rivers, lakes and groundwater, which only account for 0.26% of the total water on the earth. At present, more than 1 billion people in the world are facing the problem of water shortage. According to relevant experts' estimates, by 2025, nearly half of the world'...
