Problems solved by technology

[0005] Existing water purification devices have relatively simple functions, some floating islands have simple structures, and the absorption and purification effect of plants is limited, and the underwater part of floating islands will enter hypoxia after long-term operation state, the purification speed is slow, which affects the water purification effect
As a result, the water quality is getting worse and worse, and the maintenance management is difficult and the cost is high

Embodiment Construction

[0031] In order to further reveal the technical solutions of the present invention, the following describes the implementation of the present invention in detail in conjunction with the accompanying drawings: figure 1 As shown, a stepped water body ecological purification system includes a concrete bed body, and the concrete bed body includes three zones from top to bottom, which are respectively a floating bed zone 1, a microbial zone 2 and a sunken bed zone 3, and the microbial zone A concrete partition 4 is provided between 2 and the sunken bed area 3 . The concrete bed body is a lightweight concrete bed body, and is fixed in the water body by using concrete anchors. The bed is constructed of concrete and fixed with concrete anchors to prevent the bed from being washed away by wind and waves.

[0032] The floating bed area 1 includes a matrix layer and the emergent plants 11 planted on the matrix layer, the matrix layer includes a suspension material 13 with a density les...

Abstract

The invention discloses a multi-step water body ecological purification system. The system comprises a concrete bed body, wherein the concrete bed body comprises three regions from top to bottom, respectively a floating bed region, a microorganism region and a sedimentation bed region; a ventilating pipe is arranged in the floating bed region; a vent and a windmill are arranged at the upper end of the ventilating pipe; the windmill is fixedly arranged below and close to the vent; an aeration opening and a stirrer are arranged at the lower end of the ventilating pipe; the stirrer is fixedly arranged above the aeration opening; the lower end of the ventilating pipe deeply extends into the microorganism region; a water inlet and a water outlet are respectively formed in the left and right sides of the concrete bed body; and detachable filter screens are respectively arranged at the water inlet and the water outlet. The invention also discloses a construction method of the multi-step water body ecological purification system. The multi-step water body ecological purification system disclosed by the invention is rapid in purification speed, good in purification effect, easy to maintain and manage and low in cost.

Description

technical field [0001] The invention relates to a stepped water body ecological purification system and a construction method thereof, which belongs to the technical field of water body restoration and is applied to water areas such as river courses, lakes and small-scale domestic sewage. Background technique [0002] At present, the eutrophication of water bodies in my country is showing a trend of accelerated deterioration, and the ecosystems such as rivers and lakes have been seriously degraded, leading to a series of environmental problems. In the prior art, the methods of aquatic vegetation, biological floating island and biological sedimentation bed are generally used to restore the water body. The restoration of aquatic vegetation is conducive to the formation of an "aquatic plant-microbe-micro-animal" system, and its purification mechanism for pollutants mainly includes: 1) the absorption of nitrogen and phosphorus nutrients by aquatic plants; 2) the absorption of ...
