7. The excrement treatment device for treating domestic sewage according to claim 6, wherein: the supporting springs (1302) are arranged at equal intervals on the inner side of the cavity (1301).

8. The excrement treatment device for treating domestic sewage according to claim 1, wherein: the blanking structure (17) comprises a discharge chute (1701), a bottom plate (1702), an opposite screw rod (1703), a thread block (1704), a movable chamber (1705) and a brush barrel (1706), wherein the discharge chute (1701) is fixedly connected to the middle position of the bottom end of the second shell (14), the movable chamber (1705) is respectively arranged on two sides of the interior of the discharge chute (1701), the opposite screw rod (1703) is movably connected to the interior of the movable chamber (1705), the thread block (1704) is respectively movably connected to two ends of the middle position of the opposite screw rod (1703), the bottom plate (1702) is fixedly connected to one side of the thread block (1704), and the brush barrel (1706) is movably connected to the interiors of two ends of the discharge chute (1701).

9. The method for treating excrements for treating domestic sewage according to claim 8, wherein the method comprises the following steps: firstly, starting the variable frequency motor 2, carrying out primary solid-liquid separation on the excrement mixture standing still at the top end in the first shell 3 by using the rotary scraper 7, enabling solid excrement to enter the second shell 14 through the connecting pipe 11 for secondary processing, enabling the rest liquid mixture to fall into the bottom end of the screen frame 20, then spirally lifting the outer side of the transmission shaft 9 by using the rotary block 21 movably connected with the middle position of the bottom end of the rotary block, keeping fine residues in the screen frame 20 under the limit of the corrugated sleeve 18, and completely throwing out the liquid; then, the top end of the unidirectional screw 605 is held and lifted upwards, and then the sliding block 607 is pressed down to reset in the limiting groove 604 under the elastic force of the extension spring 606, at this time, the sliding block 607 rotates due to the engagement of the internal thread thereof with the unidirectional screw 605, so that the medicament in the storage box 601 is quantitatively added into the sewage at the bottom of the first housing 3 in batches through the leakage groove 608 by the rotating sweeping plate 603; next, a cavity 1301 is arranged in the inner wall of the second shell 14, a winding heating pipe 1303 is uniformly laid in the cavity, and the heat loss in the cavity can be effectively prevented by matching with the heat insulation cotton 1304 on the outer layer, so that the excrement fermentation time is shortened, and methane can be generated more quickly, and the purpose of recycling is achieved; then, the transverse plates 1204 at the two sides are held and pressed, so that the press plugs 1207 are inserted into the air inlet grooves 1205, and the blocking pieces 1206 at the two sides fixed by the spring shafts are pushed open, at the moment, the excrement solid in the second shell 14 enters the box body 1202 through the air inlet grooves 1205 under the attraction of external force, and is subjected to double filtration and adsorption by the filter frame 1203 and the activated carbon particles 1209, so that pungent odor in the gas is removed; finally, the opposite screw rods 1703 on the two sides of the discharging groove 1701 rotate in the same direction, so that the bottom plate 1702 is driven by the thread block 1704 to slide at a constant speed between one side inside the movable chamber 1705, the adjustability of the area of the outlet is realized, the residual waste residues on the top end of the bottom plate 1702 can be effectively removed by the brush barrel 1706 which is matched with the movable connection of the two ends inside the discharging groove 1701, the bearing objects with multiple specifications and sizes can be adapted, and the pollution and waste caused by the leakage of the waste residues are avoided.
