System and method for efficiently improving coastal saline-alkali soil with recycled water resources
The invention discloses a system and method for efficiently improving coastal saline-alkali soil with recycled water resources. The system comprises a soil body and a water storage well. The soil bodycomprises saline-alkali soil to be improved, a water permeable membrane layer, a water storage layer, a waterproof layer and undisturbed soil sequentially arranged from top to bottom. A water intakepipe is arranged in the water storage well. A water suction pump is arranged at the water inlet of the water intake pipe that extends to the bottom of a water intake well, and the outlet end of the water intake pipe is horizontally arranged above the surface of the saline-alkali soil to be improved. A tee junction and a valve are arranged on the water intake pipe, with one end being connected to an irrigation apparatus and another end being connected to a removal pipeline. Water is poured onto the saline-alkali soil to be improved and flows into the water storage well after washing, and then water is pumped to wash the saline-alkali soil. Such a process is repeated to wash the saline-alkali soil to be improved for the purpose of desalinization. The system and method disclosed in the invention have the advantages of simple and convenient operations, realized recycling of water resources, efficient saline-alkali soil washing with various water resources in short cycle, achieved improvement of saline-alkali soil without accumulation of salt in the surface soil, saving of fresh water resources, and low improvement cost.
本发明公开了一种水资源循环高效改良滨海滨海盐碱土的系统和方法，系统包括土壤本体和蓄水井；所述土壤本体包括从上到下依次设置的待改良盐碱土、透水膜层、蓄水层、防水层、原状土；所述蓄水井内设有取水管，该取水管进水口设有抽水泵并一直延伸到取水井底部，取水管出口端水平设置在待改良盐碱土表面上方，所述取水管上设三通和阀门，一端连接浇灌装置，一端接弃流管线。水浇灌至待改良盐碱土上，淋洗后进入蓄水井，抽水对待改良盐碱土淋洗，如此循环往复浇洒淋洗待改良盐碱土达到脱盐目的。本发明系统和方法操作简便，实现了水资源的循环利用，可高效利用各种水资源对盐碱土淋洗，周期短，达到盐碱土改良的效果，且不会返盐，节约了淡水资源，改良成本较低。
