Abstract: The present invention discloses a small integrated greening device and method for recycling wastewater, including a wastewater collection system, a microorganism and plant purification system, and a reclaimed water collection and distribution system. The method includes the following process: greywater or wastewater is collected through a pipeline and enters a water collection tank of a wastewater collection part. Lifting is performed by submersible sewage pumps, such that the lifted water enters a microorganism and plant synergistic purification and greening part. Each submersible pump is controlled by one corresponding automatic water level controller to transport the treated water to the reclaimed water-use sites. The device and method provided by the present invention utilize the physical and chemical action of a filler and the synergistic purification effect of microorganisms and plants to purify the greywater, and the purified reclaimed water is used for flushing toilets, watering trees or other purposes.
