Ecological filter bed for river regulation

Abstract

The invention discloses an ecological filter bed for river regulation. The ecological filter bed comprises a slope body, the slope body comprises a filter chamber (5) and an aeration chamber (8) arranged below the filter chamber, the filter chamber and the aeration chamber are separated through a first partition plate (13), a first filter layer (1), a second filter layer (2), a third filter layer (3) and a fourth filter layer (4) are arranged in the filter chamber, the first filter layer and the second filter layer are connected through a second partition plate (10), the second filter layer and the third filter layer are connected through a third partition plate (11), and the third filter layer and the fourth filter layer are connected through a fourth partition plate (12).

Description

technical field [0001] The invention relates to the technical field, in particular to an ecological filter bed used for river channel management. Background technique [0002] Urban black and smelly water is a water environment problem that people strongly report, which not only damages the urban living environment, but also seriously affects the image of the city. [0003] With the rapid development of my country's urban economy, the scale of the city is expanding day by day, and the urban environmental infrastructure is increasingly insufficient. After a large amount of organic pollutants, organic reduced nitrogen, phosphorus and other exogenous pollutants enter the water body, the aerobic rate is greater than the oxygen-enriched rate during the oxidation and decomposition process, and the DO in the water body is generally reduced, which means that the water body is transformed into an anoxic or anaerobic state. As a result, a large number of anaerobic bacteria multiply, ...
