Greening device for on-site treatment and recycling of rainwater and domestic sewage

Abstract

The invention relates to a greening device for on-site treatment and reuse of rainwater and domestic sewage. The greening device comprises a water storage barrel, a water distribution system, a power supply system, a greening wall and a water sterilizer, a water inlet is formed in the top of the water storage barrel, a filter screen is arranged in the water storage barrel, the water storage barrel is divided into a sewage storage chamber and a water storage chamber through the filter screen, the sewage storage chamber is connected with a sewage discharging pipe, and the water storage chamber is connected with a water discharging pipe which is provided with a control valve. The water distribution system comprises a liquid level instrument, an automatic control device, a water pump and a water distribution pipeline, the automatic control device is used for controlling operation of the liquid level instrument and the water pump, the drainage pipe is connected with the automatic control device, and an inlet of the water distribution pipeline is connected with the water pump; the greening wall comprises a first water column, a second water column and a plurality of planting groove sets, the planting groove sets are sequentially arranged from top to bottom, each planting groove set comprises a first planting groove and a second planting groove which are inclined and crossed, and plants are planted in the planting grooves. Rainwater and sewage can be resourcefully treated and recycled on site, the air quality is improved, and the urban greening rate is increased.

Description

technical field [0001] The invention relates to the technical field of water pollution treatment, in particular to a greening device for on-site treatment and reuse of rainwater and domestic sewage. Background technique [0002] At present, the utilization of rainwater resources is of core significance in the construction of sponge cities. It can not only reduce the peak of rainfall during the rainstorm period, so as to prevent and control waterlogging and realize the temporal and spatial adjustment of water resources; The non-point source pollution of water body caused by runoff can reduce the environmental pressure of water body, which is beneficial to the treatment of black and odorous water body and the ecological environment of water body. In addition, the demand for green infrastructure is increasing today. As an innovative space-saving system, the three-dimensional green wall can improve air quality, strengthen the hydrological cycle, and improve the urban greening ra...
