Rainwater collection and purification tree pool in arid and semi-arid regions

Abstract

The invention relates to a rainwater collection and purification tree pool in arid and semi-arid regions. The rainwater collection and purification tree pool comprises an inner wall and an outer wall,the inner wall and the outer wall form a water storage zone, first water outlets are formed between the bottom of the inner wall and the water storage zone, and overflow ports are formed in the top of the inner wall; a water purification zone is disposed in the inner wall, a water filtering zone is disposed on the top of the water purification zone, and the outer surface of the water filtering zone fits the inner wall; a water distribution plate is disposed in the middle of the water filtering zone, and the bottom of the water distribution plate extends to the water purification zone; a darkgroove is formed in the water filtering zone, and a height difference is formed between the dark groove and the water distribution plate; water catchment channels are formed in the top of the water storage zone, and grilles are arranged on the tops of the water catchment channels. The combination of the water purification zone and the water storage zone can achieve automatic water replenishment ofgreen plants during an intermittent period of rainwater; through arrangement of multi-stage water filtering facilities, sufficient filtering and storage of the rainwater are achieved. At the same time, multiple water storage units are designed to achieve graded storage of the rainwater, and water supply to the plants is optimized.

Description

technical field [0001] The invention belongs to the technical field of municipal engineering facilities, in particular to a tree pond for collecting and purifying rainwater in arid and semi-arid areas. Background technique [0002] Most areas in northern my country are arid and semi-arid areas. Due to the drought, the water evaporation is relatively large, the rainfall is relatively concentrated, and the amount of road particle pollutants is large. Therefore, a tree pond that can collect and utilize rainwater is particularly important in the construction. With the construction of a beautiful hometown in the country, rural road landscapes are becoming more and more popular. Due to the imperfect municipal drainage facilities in rural construction, the rainwater runoff in rural areas has not been fully utilized. At present, road tree ponds only store water by setting foundation pits, and the evaporation of rainwater in arid and semi-arid areas is large, which fails to fully rea...

Problems solved by technology

With the construction of a beautiful hometown in the country, rural road landscapes are becoming more and more popular. Due to the imperfect municipal drainage facilities in rural construction, the rainwater runoff in rural areas has not been fully utilized.

At present, road tree ponds only store water by setting foundation pits, and the evaporation of rainwater in arid and semi-arid areas is large, which fails to fully realize the maximum utilization of rainwater. The water permeability and water storage capacity of such foundation pit water storage tree ponds are poor. The ability to lack water during intermittent rainfall is not perfect; at the same time, research on the comprehensive utilization of rainwater in tree ponds has also been carried out in China, but the purification and recycling of rainwater has not been realized, and the automatic water replenishment function for green plants cannot be guaranteed during intermittent rainwater, resulting in rainwater utilization. lower
