Draining pipe network salt-discharging apparatus for saline-alkali land

Abstract

The invention relates to the technical field of saline-alkali treatment and discloses a draining pipe network salt-discharging apparatus for a saline-alkali land. The apparatus comprises a soil filtering layer. A water collection pipe is arranged on the bottom of the soil filtering layer; a water conduit is arranged on the bottom of the water collection pipe; the right side of the water conduit is provided with a salt discharging device; a filtering cavity is arranged on the left side of a cavity of the salt discharging device; the right side of the filtering cavity is equipped with a filtering structure; a salt discharging pipe is mounted on the bottom of a crystal piling port; and a water collection pond is mounted on the bottom of the salt collection pipe. Saline-alkali water in the soil can be effectively filter via the soil filtering layer; solvent salt in the water can be effectively eliminated via the filtering layer, so saline-alkali in the water can be filter and water quality can be improved; the filtered water is discharged via the water discharging pipe; filtered and separated saline-alkali accumulates and stacks on the crystal piling port; saline-alkali crystals can be brought into the salt discharging pipe when a salt discharging valve is opened; and then the crystals is discharged into the water collection pond on the bottom of the salt discharging pipe.

Description

technical field [0001] The invention relates to the technical field of saline-alkali treatment, in particular to a salt-discharging device for a saline-alkali land filtration pipe network. Background technique [0002] The salt drainage device of the water filter pipe network is a device used to control the salinization of the land. The saline-alkali land refers to the salinization of the land, and the soil has a high salt content. The salt contained in it affects the normal growth of the crops. Influenced by the salt content, the survival rate is relatively low, especially in landscaping projects, once the geology is saline-alkali land, the plant survival rate is low, and greening is very difficult. It rises to the surface through the interstitial action of the soil, forming soil salinization. The key to greening saline-alkali land is to control the salinity of the soil. The greening of traditional saline-alkali land only needs to be carried out by backfilling with foreign ...
