Abstract

The invention discloses a system and method for discharging alkali and washing salt in saline-alkali soil by utilizing a solar heat collection drying pipe. Condensed water resources are obtained from saline-alkali water by utilizing a solar photo-thermal method, evaporation of the saline-alkali water can be accelerated, separation of salt and alkali from fresh water is promoted, finally a large amount of condensed fresh water is obtained, and water resource shortage can be relieved, and the alkali removal and salt leaching efficiency of saline-alkali soil can be improved.

Description

technical field [0001] The invention relates to the technical field of saline-alkali water purification, in particular to a system and a method for discharging alkali and washing salt on saline-alkali land by utilizing solar heat collection drying tubes. Background technique [0002] The salinity of saline-alkali water in saline-alkali land in southern Xinjiang is usually in the range of 1-3g / L, which is much lower than that of seawater (30g / L), but the content of saline-alkali is relatively high. In order to reduce the saline-alkali content of the soil in southern Xinjiang to meet the planting requirements, the local area adopts the traditional method of flooding the ground with salt. Waste a lot of water resources. Therefore, there is a need for a method to alleviate the shortage of water resources and effectively improve the discharge of alkali and salt in saline-alkali land, so as to provide irrigation water to the planting areas in southern Xinjiang. Contents of the ...
