<p>A seawater desalination device and method thereof, relating to a seawater device and method thereof that use a combination of an electrolysis technique, a capacitive adsorption de-ionization technique, and a low-pressure reverse osmosis technique. The device is disposed with an electrolytic purification system, a capacitive adsorption de-ionization system, and a low-pressure reverse osmosis system. The electrolytic purification system has a stop valve, a water supply pump, an electrolysis machine, a sedimentation tank, and a micro-filtration device; the capacitive adsorption de-ionization system has a stop valve, a lifting pump, a safety filter, a water supply pump, a capacitive adsorption de-ionization device, a preliminary freshwater storage tank, and a concentrated water booster pump; the low pressure reverse osmosis system has a stop valve, a water supply pump, a safety filter, a high pressure pump, a low pressure reverse osmosis membrane assembly, and a freshwater storage tank. First, performing electrolysis, then performing capacitive adsorption de-ionization to preliminarily remove salt, and finally performing low pressure reverse osmosis to remove salt. The process is short, requires small investments, and has little environmental pollution. The reverse osmosis system has low requirements for material, is cheap, and addresses the domestic production problem. The invention is easy to operate, uses little energy, and has high desalination efficiency, low manufacturing costs, a high concentration of apparatuses, and a small volume.</p> |
