the fourth step: because the interior of the planting pool 14 can be equally divided into three groups of purification cavities through the action of the first partition plate 13 and the second partition plate 15, in rainy season, sewage can flow into the interior of the second component purification cavity from the water distribution hole 34 formed in one side of the first partition plate 13 after being purified by the first group of purification cavities, and in the process that the sewage flows into the second component purification cavity through the water distribution hole 34, the contact time between the sewage and air can be increased, so that the sewage can carry more oxygen, the biochemical degradation effect of microorganisms in the planting pool on pollutants is improved, because the horizontal height of the second partition plate 15 is higher than that of the first partition plate 13, the sewage can be discharged from the drain pipe 18 after being purified by the three purification cavities connected in series, the sewage treatment effect of the device is ensured, and meanwhile, the sewage directly flows into the drain pipe 18 from the tops of the three groups of purification cavities to be discharged in rainy season, at the moment, the purification cavities in the planting pond 14 run in parallel, so that the impact force of the sewage on the artificial wetland in the rainstorm period is greatly reduced, the capability of resisting the sudden high-water-load impact of the artificial wetland system is improved, and the stable operation of the artificial wetland system in different seasons is ensured.

In summary, according to the above technical solution of the present invention, when sewage is fed into the tank 1 through the liquid inlet pipe 2, the internal water pressure is gradually increased with the increase of the sewage in the tank 1, so that the siphon 9 rapidly absorbs the sewage in the tank 1 and guides the sewage into the planting pond 14 for purification, the whole process automatically operates by the gravity generated by the liquid level difference, when the sewage level in the tank 1 drops to be at the same level as the drainage pipe 23, air enters into the siphon 9 and automatically stops drainage, so that the intermittent sewage outflow can be realized, the fixed pipe 41 is in a full state when distributing water, the purpose of uniform water distribution is achieved, meanwhile, air can be brought in when distributing water, so as to meet the requirement of biological metabolism, when the siphon 9 performs siphon work, the mesh cylinder 22 sleeved outside the siphon can prevent the sewage from being blocked by impurities, the normal operation of the device is influenced, because one end of the water conduit 23 is close to one side of the net cylinder 22, when the water conduit 23 is used for pumping liquid, impurities in the sewage are uniformly gathered at one side close to the water conduit 23, in the process of adding the sewage into the box body 1, the sewage firstly falls on the upper surface of the guide plate 3 and falls through the diversion trench 5 on the upper surface of the guide plate 3, the falling sewage impacts the water collecting hopper 6, when the water collecting hopper 6 is impacted, the rotating column 7 can drive the brush roller 24 to rotate, because the brush roller 24 is contacted with one side of the net cylinder 22, one end of the drainage tube 23 far away from the siphon 9 and the brush roller 24 are positioned on the same horizontal plane, the outer wall of the net cylinder 22 can be cleaned through the brush roller 24, the condition that the net cylinder 22 is blocked due to the gathering of the impurities in the sewage is avoided, and the excessive sewage can be collected through the water collecting tank 20 arranged in the box body 1, when the siphon 9 for reducing sewage in the box 1 is not siphoned for a long time, the air pressure in the overflow pipe 33 is reduced, the piston 38 can move downwards to pull the traction rope 19 and the cover plate along with the gradual reduction of the air pressure in the overflow pipe 33, when the cover plate is pulled, the sewage in the water collecting tank 20 can flow into the overflow pipe 33 and the siphon 9 through the liquid guide pipe 11 to wet the siphon 9, so as to avoid the drying of sludge in the siphon 9, the sewage can be equally divided into three groups of purification chambers under the action of the first partition plate 13 and the second partition plate 15 in the planting pond 14, and in the rainy season, the sewage can flow into the second component purification chamber from the water distribution hole 34 formed in one side of the first partition plate 13 after being purified by the first group of purification chambers, so that the contact time between the sewage and the air can be increased in the process of flowing into the second component purification chamber through the water distribution hole 34, make sewage can carry more oxygen, improve the biochemical degradation of the inside microorganism of planting pond to the pollutant, because the level of second baffle 15 is higher than first baffle 13, consequently can make sewage discharge by drain pipe 18 after the series connection purification of three purification chamber, the treatment effect of device to sewage has been guaranteed, simultaneously in rainy season, sewage directly flows into drain pipe 18 from the top of three groups purification chamber and discharges, the purification chamber of planting pond 14 inside at this moment is parallel operation, greatly reduced the stormy season sewage to constructed wetland's impact force, improve the ability that constructed wetland system resisted unexpected high water load impact, it can the steady operation in different seasons to have guaranteed constructed wetland system.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
