Purification and spray irrigation system for polluted irrigating water

Abstract

The invention provides a purification and spray irrigation system for polluted irrigating water. The system includes a water pool, a water supply pump, a first high voltage electrostatic generator, a solar battery pack, a second high voltage electrostatic generator, a cation reverse osmosis membrane purifier, a spray irrigation nozzle, an electrostatic purification module and an anion reverse osmosis membrane purifier. The electrostatic purification module comprises a rod-type positive electrode, a tubular negative electrode, a cation / water separator, and an anion / water separator. The system achieves synchronous deionization and sterilization of polluted irrigating water, and prevents soil, surface water and ground water from being polluted to keep the water environment security. The system has the advantages of being stable and safe in operation, simple in device structure and high in efficiency, and meets the requirements of agricultural irrigation.

Description

technical field [0001] The invention relates to the field of spray irrigation for purifying polluted irrigation water, in particular to an irrigation water purification spray irrigation system that utilizes a high-voltage electrostatic field to cooperate with a reverse osmosis membrane to purify water bodies and form a space electric field during the spray irrigation process to promote plant growth. Background technique [0002] With the rapid development of the national economy and the improvement of people's living standards, the amount of sewage discharge has intensified, and the water quality of major waters in the country has been polluted. The irrigation water contains toxic and harmful substances, causing land organic pollution, heavy metal pollution, and acid-base salt pollution. Surface water And groundwater eutrophication, the water environment is polluted, which poses a huge challenge to the food safety of agricultural products. [0003] At present, rural irrigati...
