The environmental-friendly micro domestic sewage treatment method according to claim 1, characterized in that: firstly, when domestic sewage is treated and chemical reagents need to be added for reaction, the cover plate (9) is lifted upwards, the cover plates (9) on the two sides are combined behind the cover plates, the sliding rod (11) penetrates through the insides of the slots (2) on the two sides to fix the cover plate (9), and the sealing strip (12) and the sealing ring (10) on one side of the cover plate (9) prevent gas generated by sewage reaction in the tank body (5) from being discharged outside to cause pollution; later, when domestic sewage is treated, the first motor (102) is started to drive the rotating shaft (108) to rotate and simultaneously drive the fan blades (106) to rotate, the fan blades (106) rotate to generate vortex inside the tank body (5), the vortex is influenced by the vortex, impurity particles can be concentrated at the center of the vortex, the vertical rods (103) are pushed to drive the filter screen frame (104) to descend, dust and impurities are covered inside the screen mesh (105), the cover plate (9) is covered at the moment, the cover plate (9) can press the vertical rods (103) to fix the filter screen frame (104), and then reaction is carried out, so that the impurities inside the sewage can be concentrated together to be conveniently cleaned, and the sewage reaction treatment is not influenced;

then, when a chemical reagent is introduced to react with sewage, after the cover plate (9) is covered, the sealing plate (302) can be pulled in the reaction, the sealing plate (302) is pulled away from the bottom end inside the placing box (304), and gas generated in the reaction passes through the grating (303) and enters the top end inside the placing box (304) to be quickly absorbed by the activated carbon particles (305) inside, so that harmful gas, smell and the like generated in the reaction can be absorbed in the reaction.
