Description
Technical Field
The invention relates to a salt water desalination and salt fixation system, and belongs to the technical field of saline-alkali soil remediation and salt water desalination.
Background
Salt is an essential element by which humans and plants are dependent for life. However, the salt is not harmful, the saline-alkali soil is damaged by the salt, and the normal growth of crops is influenced to a certain extent by the accumulation of the salt in the soil. According to incomplete statistics of the combined country textbook organization and the grain and agriculture organization, the area of the saline-alkali soil is 9.5438 hundred million hectares in the world, wherein 9913 million hectares in China. Most of the saline-alkali soil in China is related to the accumulation of soluble salts and carbonates in soil, the salinization degree is generally high, and serious saline-alkali soil plants can hardly survive.
Saline-alkali soil is formed and developed under certain environmental conditions, and among numerous environmental factors, climate drought, strong ground evaporation and relatively low and flat topography cause stagnation or collection of surface runoff and groundwater level close to the surface are main reasons for the soil salt accumulation process.
Because the types, causes and climatic characteristics of saline-alkali soil in various regions are different, the technology and the method for improving and utilizing the saline-alkali soil are different. Salt elimination in water conservancy projects is the most common method for improving the saline-alkali soil at present, and by introducing fresh water to irrigate and wash salt, the salt content of the soil is reduced, and the improvement of the saline-alkali soil is accelerated. However, such conventional operations are obviously not feasible in some regions where fresh water resources are very scarce. In addition, fresh water is adopted to irrigate and wash salt, and a large amount of salt water generated after salt washing is discharged into a river, so that the ecological environment of the river and the soil of a downstream river basin are harmed; in areas without drainage conditions, saline water after salt washing can also permeate underground, so that the underground water level rises, and the salinization degree of underground water and soil is increased.
The saline-alkali soil is a chronic disease on the ground and is a precious land resource.

In the 'three north' areas (north China, northeast China and northwest areas) mainly distributed in saline-alkali soil in China, the cold energy resources are abundant in the long winter, and the solar energy resources are abundant in the sufficient illumination. The cold energy resources and the solar energy resources in the regions are comprehensively utilized to carry out natural freezing desalination, salt fixation evaporation and condensation desalination on saline water of the saline-alkali soil, and the saline-alkali soil is irrigated with ice melting and condensed fresh water to wash the salt. Through the development and utilization of unconventional water resources such as underground salt water and the like, the ecological restoration with low investment, low energy consumption and no pollution to saline-alkali soil is realized in the 'three north' area deficient in fresh water resources.
