The invention relates to a domestic sewage treatment method, which comprises the following steps: firstly, the device is buried underground, the upper part of the main body 1 is exposed out of the ground, so that the observation of the warning post 36 and the plugging of the sealing plug 39 are convenient, then the first water inlet pipe 2 is used for discharging washing wastewater, the second water inlet pipe 3 is used for discharging kitchen waste water and bathing wastewater, the sewage discharge pipe 51 is used for discharging toilet wastewater or excrement, the third toggle paddle 45 can continuously rotate anticlockwise under the action of the repulsive force of the second eccentric magnet 49 on the first eccentric magnet 47, the third toggle paddle 45 can shift the bottom of the light push rod 44 upwards in the anticlockwise rotating process, and the distance between each first eccentric magnet 47 and the light push rod 44 is fixed, so that the light push rod 44 can return to the original position under the action of gravity after moving upwards for a certain distance, the vertical reciprocating movement of the light push rod 44 is realized, and the vertical reciprocating swing of the light filter plate 24 can be continuously performed, when the laundry sewage flows into the first water inlet pipe 2, the first dial shaft 5 can rotate anticlockwise due to the impact of flowing water, then the rack scraping frame 7 can move rightwards by overcoming the elastic force of the first spring 8 through meshing transmission, and meanwhile, the first rack transmission frame 12 drives the dredging frame 10 to move downwards, so that the filter hole 9 is smooth, the laundry wastewater flows into the first water storage tank 6 through the filter hole 9, the laundry wastewater flowing into the first water storage tank 6 can flow out through the first limiting pipe 13 after accumulating to a certain volume, so that the laundry wastewater is prevented from overflowing from the filter hole 9, when the laundry sewage stops flowing into the first water inlet pipe 2, the rack scraping frame 7 moves leftwards under the elastic force of the first spring 8, and meanwhile, the dredging frame 10 is driven to move upwards through the first rack transmission frame 12, so that the upper end faces of the filter hole 9 and the first water storage tank 6 can be

chamber 50 sewage again, thereby be favorable to the fermentation of wastes material more, and the light filter plate 24 that can continuously tremble can the very big jam of avoiding light filter plate 24 under the washing away of cooperation sewage, and can reduce the adhesion of greasy dirt after the mixed sewage that enters into in last water storage chamber 31 mixes, then carry out secondary filter through the filter media in filtering hollow plate 30, and the sewage that has carried out secondary filter can be discharged through No. three spacing pipe 43, and mixed sewage can lead to hollow floating frame 35 to receive the buoyancy of water to rise along slide rail 33 in the process that last water storage chamber 31 filters, then scrape the cleanness to last water storage chamber 31 inner wall under the effect of scraper blade 34, and simultaneously can make warning post 36 rise along main part 1, when the filtering material in the filtering hollow plate 30 is blocked after being used for a long time, more and more mixed sewage in the upper water storage cavity 31 is generated, so that the hollow floating frame 35 continuously rises and is discharged through the second limiting pipe 42, the mixed sewage is prevented from overflowing from the left part of the second water storage tank 25, and the function of limiting the water level in the upper water storage cavity 31 is achieved, the warning column 36 at the same height for a long time can remind people of dredging the filtering hollow plate 30, when the filtering hollow plate 30 needs to be dredged, the filtering hollow plate 30 is shaken by pushing and pulling the adjusting rod 27, so that the temporary dredging effect is achieved, after the mixed sewage is secondarily treated and discharged, the left end or the right end of the adjusting supporting plate 29 is in contact with the top end of the main body 1, so that the inner cavity of the filtering hollow plate 30 is communicated with the discharging cavity 38, and the filtering material is convenient to be discharged into the storage tank 40, then empty the filter media in the storage case 40 through carrying and lifting hoist and mount ear 41, the top that will adjust backup pad 29 contacts with 1 top of main part to make the hollow slab 30 inner chamber of filtering put through mutually with unloading chamber 37, then conveniently pack the filter media to the hollow slab 30 of filtering through unloading chamber 37, will adjust the bottom and the 1 top contact of main part of backup pad 29, thereby make the hollow slab 30 of filtering be the horizontality, thereby realized the change work of filter media.

The foregoing is a preferred embodiment of the present invention, and it will be apparent to those skilled in the art that variations, modifications, substitutions and alterations can be made in the embodiment without departing from the principles and spirit of the invention.
