Abstract
The invention relates to the field of photothermal power generation, and particularly discloses a water treatment process special for a photothermal power generator. The water treatment process comprises primarily filtering tap water with gravel and carbon dust, and performing backwashing operations for a plurality of times; adding limewater into filtered water, and separating out after standing for a period of time; adding diluted alkali into treated water, flowing by a first magnetic field zone by a pipeline for magnetic treatment, causing the magnetically treated water to flow by an ultrasonic wave zone, filtering the treated water with a dialysis membrane, atomizing the filtered water by an atomizing pipe zone, and causing the atomized water to flow by a second magnetic field zone by a pipeline for magnetic treatment to obtain the required water. The water treated by the process is not scaled at high temperature and does not influence the normal operation of a photothermal power generator.
