8. The treatment method of the sewage grid treatment system for both life and industry according to any one of claims 1 to 7, wherein: comprises the following steps of (a) carrying out,
supplying water to a sewage grid treatment system by a fourth conveying pipe (23), wherein sewage flows along the height descending direction of a filtering step (22), impurities with larger particle sizes are intercepted above the filtering step (22), and the rest sewage falls into the bottom of a water tank (21);
step two, sewage at the bottom of the water tank (21) enters the first conveying pipe (14) through the water outlet; the sewage is driven by the pressurizing assembly (3) to fall into the flow divider (15) in an accelerating way;
step three, the sewage in the flow divider (15) continuously falls into the rotating range of the impeller (152), and respectively impacts the first grating plate (12) and the second grating plate (13) from the first liquid outlet (155) and the second liquid outlet (156) under the action of centrifugal force to carry out secondary filtration;
step four, when the sewage water flow on the corresponding side impacts the plate surface of the grid plate structure, the corresponding aeration ring structure continuously aerates, a part of the sewage water flow flows along the plate surface of the grid plate structure in the inclined direction, and the sewage water flow carries bubbles mixed flow to jointly wash the grid plate in the flowing process;
and step five, after the sewage is transferred from the third cavity (103) to the first cavity (101) and the second cavity (102) through the filtering process of the step three and the step four, the sewage is communicated with the second conveying pipe (104) and the third conveying pipe (105) by utilizing pump equipment, and the sewage is pumped to a subsequent process for post-filtering treatment.
