The invention relates to a multistage oxidation-membrane separation collaborative water treatment system and a process for a light-sound-electricity coupled energy field. The multistage oxidation-membrane separation collaborative water treatment system comprises three parts, namely a light-sound-electricity coupled energy field multistage oxidation unit, a dual-membrane separation unit and a disinfection and sterilization unit, wherein the light-sound-electricity coupled energy field multistage oxidation unit comprises a light-sound-electricity coupled energy field multistage oxidation reactorprovided with a light-sound ozone joint oxidation reaction zone and an electrochemical oxidation adsorption reaction zone; the dual-membrane separation unit consists of a first-stage nano-composite ultrafiltration membrane and a second-stage nano-composite ultrafiltration membrane; the disinfection and sterilization unit adopts an ultraviolet sterilizer. By using a coupling synergistic effect among an ozone oxidation technology, an ultraviolet photoxidation technology, an ultrasonic oxidation technology, an activated carbon adsorption technology, an electrochemical oxidation technology, a membrane separation technology and the like, the multistage oxidation-membrane separation collaborative water treatment system is efficiently integrated to form an integral inseparable reaction system ofwhich all parts are synergized; the multistage oxidation-membrane separation collaborative water treatment system can be used for carrying out multistage oxidation and degradation on organic pollutants in a water body and then separating and removing the organic pollutants, and effectively removing organic salts, in particular to high valence salt ions.

Description

Technical field [0001] The invention belongs to the technical field of water supply treatment, and mainly relates to drinking water treatment, in particular to a multi-stage oxidation-membrane separation collaborative water treatment system and process through a photoacoustic-electric coupling energy field, and is particularly suitable for treating slightly polluted brackish water. Background technique [0002] At present, our country is facing the dual dilemma of water shortage based on water quality and water shortage. The problem of micro-pollution of drinking water sources is becoming more and more serious. The soluble organic pollutants in micro-polluted water sources are difficult to remove under conventional treatment process conditions. Searching for a safe and efficient micro-polluted water treatment technology is an effective way to solve the water shortage. At the same time, the shortage of fresh water resources is also one of the urgent problems to be solved. Therefor...
