Ecological sinking bed

Abstract

The invention discloses an ecological sinking bed. The ecological sinking bed comprises a sinking bed body, plant planting gaskets and ecological base fixing frames, wherein the sinking bed body comprises a plurality of sinking bed modules; each sinking bed module is set to be a hollow polygonal columnar structure; the sinking bed modules are detachably connected with each other; the plant planting gaskets and the ecological base fixing frames are arranged in the sinking bed modules; the lower part of each plant planting gasket is of a net-shaped structure; each plant planting gasket is internally provided with an isolation layer and a matrix layer in sequence from top to bottom; each isolation layer is made of river sand and each matrix layer is made of planting soil; plants are planted on the planting soil; each ecological base purification unit comprises the ecological base fixing frame, a first counterweight layer and a second counterweight layer in sequence from top to bottom; each ecological base fixing frame is of a fence-shaped structure and ecological base is arranged on the ecological base fixing frame; and each first counterweight layer is made of coral sand and each second counterweight layer is made of steel slag. By adopting the manner, dual purification of a water body can be realized and the purification effect is improved.

Description

technical field [0001] The invention relates to the technical field of water body purification and restoration, in particular to an ecological sedimentation bed. Background technique [0002] In the urban environment, the environmental capacity and ecological carrying capacity of water bodies are overwhelmed, and the ecological system is greatly damaged. Water bodies such as parks and residential areas have been polluted to varying degrees. According to statistics, the water bodies of more than 90% of the parks in my country have chemical oxygen demand (COD), biochemical oxygen demand (BOD), total nitrogen (TN), total phosphorus (TP) and non-ionic ammonia, etc., which mostly exceed the national ground level. Class IV standard of water environment quality. [0003] In view of the problems of hard protection of urban landscape rivers, low water transparency, large water depth changes, and the difficulty of aquatic plants, especially submerged plants, artificial sinking has a ...

AI Technical Summary

Problems solved by technology

The existing artificial sedimentation beds mainly use phytoremediation to purify the water quality, and the purification effect is not good. To achieve the ideal purification effect, a large area of ​​plants is required, and the construction cost of the artificial sedimentation bed is greatly increased.
