the method comprises the following steps: when sewage is treated, heat generated by solar energy is utilized for primary treatment, most of precipitable particles and non-precipitable particles in the treated sewage are precipitated and collected, and then the sewage is conveyed to a second membrane reaction box (2) for treatment;

step two: solar heat collected in the solar device (3) is transferred to the heat concentration box (12) through the heat transfer pipeline (8) and then is dispersedly transferred to the heat conduction pipe (18), and when the heat concentration box (12) is pushed to move along with the pushing unit (14), the heat conduction pipe (18) enters and exits the sewage treatment cavity (19);

step three: the filtering layer structure (20) moves synchronously with the heat concentration box (12), when the filtering layer structure (20) moves towards the partition plate (17), precipitated impurities are scraped into the sewage discharge port (26) through the bottom of the sewage treatment cavity (19) and then discharged into the dust collection box (4) for collection, and when the heat conduction pipe (18) moves, the partition plate (17) can scrape and drop the impurities attached to the heat conduction pipe (18) into the sewage treatment cavity (19), so that the heat in the heat conduction pipe (18) can be normally transferred to one side of the first membrane reaction box (1) in the sewage treatment cavity (19) to form a sewage inlet pipeline (34), and the sewage inlet pipeline (34) can discharge the sewage into the sewage treatment cavity (19).
