The working principle is as follows: after rainfall begins, rainwater reaches the ground vegetation layer, is absorbed and trapped by plants and soil to reach saturation, and redundant rainwater reaches the porous space of the lower supporting component 12 through the primary filtering layer 18, so that larger impurities are intercepted and filtered in the process. When the water level in the porous space of the supporting component 12 is higher than the water level of the water collecting tank 6, pressure difference is generated on two sides, rainwater enters the water collecting tank 13, enters the interior of the water collecting tank through the grid 112 of the horizontal gravity filtering unit 11, is filtered through the fine sand layer 114 and the coarse medium sand layer 115, enters the water collecting tank 6 through the rainwater collecting pipeline 10 and is stored, impurities in the rainwater are further filtered and intercepted in the process, and the rainwater can be filtered and treated. Because the grid 112 of the horizontal gravity filter unit 11 is arranged at the upper part of the horizontal gravity filter unit, larger and heavier impurities in rainwater are deposited below the grid, and the sediment at the bottom of the water collecting tank 13 flows out of the sewage draining tank 14 by starting the sewage draining pump 8 and is finally discharged through the sewage draining pump 8 and the sewage draining pipeline 9, so that the sewage removing operation is completed.

When the water level in the water collection tank 6 approaches the water level in the porous space of the support member 12, the filtration process will stop by itself due to the loss of the water level difference. When the water collection tank 6 is pumped out by the reuse water pump for use, the water level in the water collection tank 6 drops, and forms a water level difference with the water level of the porous space of the support component 12 again, and the filtration process starts automatically. After a period of filtering operation, the reuse water pump is started through the combined action of the electric valves 17, water in the water collection tank 6 is back filled into the porous space of the support component 12, the data of the liquid level difference between the porous space of the support component 12 and the water collection tank 6 are recorded, the rising speed of the water level in the water collection tank 6 is recorded, and when the rising speed of the water level in the water collection tank 6 is reduced to a set value, the situation that the impurities in the horizontal gravity filtering unit 11 are too much and the filtering capacity is greatly reduced is shown, and the back flushing process is started.
