The invention relates to an artificial wetland for treating rural domestic sewage, which is characterized in that when in operation, domestic sewage is firstly conveyed to a filtering mechanism, increased solid impurities in the domestic sewage are filtered through the filtering mechanism, then the filtered sewage is discharged into a sewage collecting tank, at the moment, the sewage collecting tank plays a role in controlling and adjusting the water level of the sewage, meanwhile, an induced draft fan is started to generate strong suction force in a gas collecting hood, then the unpleasant odor in the sewage collecting tank is absorbed into the induced draft fan by the gas collecting hood, then the induced draft fan conveys the unpleasant odor into an active carbon adsorption tank, the active carbon adsorption plate absorbs the unpleasant odor through the adsorption effect of the active carbon adsorption plate in the active carbon adsorption tank, then the active carbon adsorption tank discharges the treated unpleasant odor out of the active carbon adsorption tank, then the sewage is conveyed into a plant tank through a sewage pump of the sewage collecting tank, the sewage is purified through the physical, chemical and biological synergism of a biological sewage collecting hood, then the plant tank discharges the sewage into the sewage tank, and finally the sewage is discharged into the sewage tank through the sewage collecting tank, and finally the liquid level of the sewage is changed through a piston when the liquid level is controlled by a piston in a control piston, and the piston is directly moved in a longitudinal direction when the water level is changed, and the water level is changed, so that the piston is changed, and the pressure is directly stressed by a piston is moved in a vertical direction when the piston is changed through the control of the piston when the piston in the water level of the water tank, at this moment, the control piston drives the liquid level telescopic rod to move longitudinally in the mounting plate by a large margin, when the sewage liquid level in the sewage water collecting tank is too high, at this moment, the control piston pushes the liquid level telescopic rod to extrude the control spring to move upwards, when the sewage liquid level exceeds the warning height, at this moment, the sliding block at the upper side is separated from the sliding cavity of the liquid level telescopic rod through the jump-out hole, then the pushing spring at the upper side pushes the baffle at the upper side to move left, and simultaneously the upper baffle drives the upper indicating plate to be taken out of the upper clamping block through the mounting block at the left side of the power rod at the upper side, at this moment, the upper indicating plate rotates to a vertical state under the driving of the upper coil spring, at this moment, workers can know that the liquid level of the sewage water collecting tank exceeds the standard, at this moment, the sliding block at the lower side is separated from the sliding cavity of the liquid level telescopic rod through the jump-out hole, then the pushing spring at this moment, the baffle at the lower side is pushed left, at this moment, the lower indicating plate is taken out from the lower clamping block through the mounting block at this moment, the lower indicating plate is rotated to a vertical state under the driving of the coil spring, at this moment, workers can immediately take remedial measures after the liquid level is low.
The terms "front", "back", "left", "right" and the like are used herein for illustrative purposes only.
The foregoing is merely a preferred embodiment of the present invention, and it should be noted that it will be apparent to those skilled in the art that modifications and variations can be made without departing from the technical principles of the present invention, and these modifications and variations should also be regarded as the scope of the invention.
