Abstract

The invention discloses a seawater treatment method with synergistic effect of electrostatic adsorption and ultrasonic wave, which comprises the following steps: 1) enabling seawater to pass through a sealed container filled with a macromolecular resin adsorption material, and attracting, retarding and capturing anions and cations in the seawater by utilizing resin particles with positive and negative electrostatic charges of the macromolecular resin adsorption material, separating the wastewater from the seawater to obtain pretreated water; (2) under the synergistic effect of ultrasonic waves, regenerating the resin particles which are subjected to saturated adsorption in the step (1) by using desalted water, so that the resin particles desorb ions which are adsorbed and captured by the resin particles; and (3) treating the pretreated water obtained in the step (1) through reverse osmosis equipment to obtain desalted water. And (4) carrying out vibration desorption on the original seawater and the macromolecular resin adsorption material in the catcher by acoustic cavitation, and collecting and utilizing the obtained high-concentration saline water.

Description

【Technical field】 [0001] The invention relates to the technical field of seawater desalination treatment, in particular to a seawater treatment method with the synergistic effect of electrostatic adsorption and ultrasonic waves. 【Background technique】 [0002] The ratio of salt water to fresh water on Earth is about 97.47 to 2.53. The composition of seawater is very complex. It is roughly divided into water and salt. Sea salt contains more than 80 elements, mainly including cation Na. + , K + , Ca 2+ , Mg 2+ , Sr 2+ ; anion Cl - , Br - , SO4 2- , CO 3 2- , F - etc., accounting for 99.9% of the total salt composition. How to separate salt from seawater and achieve the purpose of desalination is a worldwide problem. [0003] At present, there are related studies. For example, Chinese Patent Application No. 201710598513.0 discloses a seawater desalination polymer flocculant, which is composed of 20%-40% acrylamide aqueous solution, 10%-20% MPS, 10%-25% AANa, 20% -2...
