Star-shaped water filter well and its high-efficiency water purification system

Abstract

The invention discloses a star-shaped filer well and a high-efficiency water purification system thereof. One end of an inner ring cutoff wall of the high-efficiency water purification system is positioned at a centroid close to a boundary cutoff wall of the high-efficiency water purification system; the other end of the inner ring cutoff wall intersects with the boundary cutoff wall of the high-efficiency water purification system at a position with a distance of L to one corner of the boundary cutoff wall of the high-efficiency water purification system; a middle part of the inner ring cutoff wall is wound in a continuous broken line or curve shape; a same width L is increased for each circle; the inner ring cutoff wall of the high-efficiency water purification system forms an annular band-shaped space for continuously purifying water; a star-shaped filter-well water outlet well group is arranged at one end of the band-shaped space; a star-shaped filter-well water inlet well group is arranged at the other end of the band-shaped space; the band-shaped space is filled with purification permutite. The star-shaped filer well and the high-efficiency water purification system thereof which are disclosed by the invention have the beneficial effects that the required space is small; a construction speed is high; a water permeation velocity is high; a filtering speed is high; water quality is obviously improved; moreover, the filter well is convenient to process, saving in material and high in strength.

Description

technical field [0001] The invention belongs to the technical field of sponge city and water treatment, in particular to a star-shaped water filter well and its high-efficiency water purification system. Background technique [0002] Sponge city is a new generation of urban stormwater management concept. It refers to the city's good "elasticity" in adapting to environmental changes and responding to natural disasters caused by rainwater. It can also be called "water elastic city". The international general term is "low-impact development rainwater system construction", which absorbs, stores, infiltrates, and purifies water when it rains, and "releases" the stored water and utilizes it when needed. [0003] At present, when the heavy rain comes, the permeable pavement cannot quickly absorb and store water, resulting in a large amount of rainwater loss, thus failing to achieve the purpose of water seepage and water purification, and may cause huge disasters; however, it cannot...
