Problems solved by technology

However, these methods may result in discontinuity of operation or inefficiency in water vapor generation
Additionally, highly concentrated salts diffuse back into solution instead of being harvested, wasting the opportunity to gain access to valuable mineral resources

Abstract

The invention relates to a device and a method for treating a landfill leachate membrane separation concentrated solution through surface photo-thermal evaporation, and belongs to the technical field of landfill leachate membrane concentrated solution treatment. The device comprises a condensing lens, a reaction tank, an evaporation table, a hydrophilic porous material layer, a photo-thermal porous material layer, an inclined transparent condensation top cover, a transparent side wall, a crystal salt collection box, a condensate water collection tank and a condensate water outlet, the condensing lens is embedded into the inclined transparent condensing top cover; the inclined transparent condensation top cover and the transparent side wall are arranged above the crystal salt collecting box in a covering mode; the reaction tank is arranged in the crystal salt collecting box; the evaporation table is located at the edge of the reaction tank, the hydrophilic porous material layer and a photo-thermal porous material layer are sequentially attached to the evaporation table from bottom to top, and the hydrophilic porous material layer extends to the side wall of the reaction tank; the condensate water collection tank is located around the inner wall of the transparent side wall. Air internal circulation exists in the reactor, air convection on the surface of the photo-thermal material is promoted, and the surface evaporation rate of the photo-thermal material is increased.

Description

technical field [0001] The invention belongs to the technical field of treatment of landfill leachate membrane concentrate, and more specifically relates to a device and method for surface photothermal evaporation treatment of landfill leachate membrane separation concentrate. Background technique [0002] With the continuous development of my country's urban economy, the expansion of urban scale, and the substantial improvement of residents' living standards, the total amount of urban garbage generated is increasing at an average annual rate of 8% to 10%. In 2018, the national domestic waste removal volume reached 228 million tons. According to estimates, my country will add about 400 million tons of municipal waste in 2030, and about 500 million tons in 2050. The problem of waste disposal has become increasingly prominent. Sanitary landfill is the most traditional and main way to dispose of garbage in my country and most other countries, and the method is simple. The dis...
