Problems solved by technology

However, when light hits the surface of the water, reflection or refraction usually occurs, which greatly reduces the utilization rate of solar energy.
[0005] In addition, the water quality of condensed water collected after traditional seawater desalination has problems such as small molecule volatile organic compounds and boron exceeding the standard, which urgently need to be solved by technical optimization

Embodiment Construction

[0029] like figure 1 and 2 As shown, the dual-function device for solar seawater desalination and pollutant removal includes a water sample bottle 1 , a peristaltic pump 2 , a water recovery mechanism 3 , a balance scale 5 and a xenon lamp light source device 4 .

[0030] Wherein, the water sample bottle 1, the peristaltic pump 2 and the water recovery mechanism 3 are sequentially connected by a hose. The top of the water sample bottle 1 is provided with a dosing port, the outlet of the water sample bottle 1 connected with the peristaltic pump 2 is provided at the bottom side, and the inlet connected with the circulation tank 304 is provided at the upper side. The water sample bottle 1 can be used to contain water samples such as seawater, industrial waste water or domestic sewage. Oxides such as persulfate can be added to the dosing port to use the heat of water evaporation for thermal activation to achieve simultaneous optimal removal of various pollutants, and samples can...

Abstract

The invention relates to a dual-function device for solar seawater desalination and pollutant removal, which includes a water sample bottle, a peristaltic pump, and a water recovery mechanism that are sequentially connected through pipelines; the water recovery mechanism includes a water storage chamber and a The upper light-transmitting condensation plate, the water storage chamber and the light-transmitting condensation plate form a closed space; the water storage chamber is divided into a circulation tank and a collection tank by a partition, and there is a gap between the partition and the light-transmitting condensation plate. The light-transmitting condensation plate is located at one end of the circulation tank higher than one end of the collection tank; the pipeline of the peristaltic pump is connected to the water inlet on the side wall of the circulation tank. Based on gas-liquid interface heating, the device simultaneously realizes seawater desalination and desalinated water quality control, ensuring the water quality and quantity of desalinated water.

Description

technical field [0001] The invention relates to the field of seawater desalination, in particular to a dual-function device for solar seawater desalination and pollutant removal. Background technique [0002] With the rapid development of industry and agriculture in society, the population has increased rapidly, and the demand for water resources has increased day by day. At the same time, the problem of water pollution has become more serious, resulting in a serious shortage of clean and safe fresh water resources. At present, effective methods to solve the shortage of fresh water resources are desalination of seawater / brackish water and recycling of water resources (sewage and wastewater). [0003] Traditional desalination of seawater and brackish water is mainly divided into two categories: phase change method and non-phase change method, mainly including multi-stage flash evaporation method, reverse osmosis method, electrodialysis method, etc., all of which have the comm...
