A multifunctional ecological tree pool

Abstract

The multi-functional ecological tree pool provided by the present invention includes planting area, purification area and pretreatment area arranged sequentially from inside to outside. From top to bottom, the pebble layer, water distribution layer, gravel layer, aluminum sludge filler layer and anaerobic reaction layer are arranged inside the first water outlet in sequence. The planting area is planted soil layer and first-level support device from top to bottom. and a second-level feeding device; wherein, the first-level feeding device includes a first box body, a first water suction and drainage rod and a permeation drainage tube, and the second-level feeding device includes a second box body and a second water outlet on the top. The water absorption and drainage rod and the permeation drainage pipe are connected to the first box from the bottom of the gravel layer, and the side wall of the second box is provided with a permeable groove connected to the anaerobic reaction layer. The invention is easy to maintain, does not need manual irrigation, can realize enhanced denitrification and dephosphorization, and provides nutrients for plants, and can be used in municipal roads, parks and residential areas.

Description

technical field [0001] The invention relates to the technical field of sponge city construction, in particular to a multifunctional ecological tree pond. Background technique [0002] Due to the rapid development of urbanization, the increase of impervious pavements in cities makes urban waterlogging and excessive flood peak runoff easy to occur, which in turn leads to a large amount of pollutants entering the municipal pipe network and increasing the bearing load of the municipal pipe network. Sponge city construction is a complex and long-term process, following the principles of ecological priority, coordinating the systematic nature of natural precipitation, surface water and groundwater, coordinating water supply, drainage and other water recycling links, and maximizing the accumulation of rainwater in urban areas , infiltration and purification, to promote the utilization of rainwater resources and ecological environment protection. [0003] The ecological tree pond i...

Problems solved by technology

[0003] Ecological tree pools are an important part of the construction of sponge cities. In the application of ecological tree pools in the prior art, most of the trees are irrigated manually. On the one hand, the utilization rate of water resources is not high, time-consuming and laborious, and it is easy to generate water accumulation Causes plant rotten roots, breeds mosquitoes, and reduces the user experience of the public; trees grow without sources of nutrients, and trees need to be "infused" manually to increase the probability of plant survival

In addition, the main function of the existing ecological tree pool technology is still to regulate and store rainwater, and cannot strengthen the removal of nitrogen, phosphorus and organic pollutants in rainwater
