Water body purification device based on ecological pervious concrete

Abstract

The invention discloses a water body purification device based on ecological pervious concrete. The water body purification device comprises a solar power generation system, a metal cylinder, a plurality of groups of ecological purification components, a water filtering frame and a scattering spray head; the solar power generation system comprises a solar panel and an energy storage assembly; a trash holding net and a submersible pump are installed in a cavity of the metal cylinder, and the trash holding net is detachably connected with a water inlet of the metal cylinder. The submersible pump is positioned at the bottom of the metal cylinder cavity; the water filtering frames uniformly surround the metal cylinder, and the outer edge of the top end of the metal cylinder is connected with the outer parts of the water filtering frames; the water filtering frame comprises a frame body and a buoyancy sponge supporting plate, and a water outlet is formed in the buoyancy sponge supporting plate and extends to the bottom of the frame body; and the ecological purification assembly comprises aquatic plants, two layers of ecological pervious concrete and a mineral material filtering layer. According to the invention, COD, TP and TN are effectively degraded, and integration of multiple functions of water surface garbage cleaning, water quality purification, lake surface landscape and increase of dissolved oxygen in water can be realized.

Description

technical field [0001] The invention belongs to the technical field of water body purification, and in particular relates to a water body purification device based on ecological permeable concrete. Background technique [0002] In recent years, while my country's social economy is developing rapidly, it has neglected the coordinated development of the ecological environment. Due to the lag in the planning of the urban drainage network in the early stage, most of the urban drainage system has stayed in the combined system of rain and sewage. system, causing a large amount of sewage to flow into the river, resulting in a decline in the quality of the urban ecological environment. Nearly 80% of the lake water in our country has eutrophication, the dissolved oxygen in the water has dropped sharply, and the lake ecosystem has been severely damaged. More than 40% of river water bodies have been polluted and cannot provide people with domestic water directly. The amount of organic...

Problems solved by technology

More than 40% of river water bodies have been polluted and cannot directly provide people with domestic water

The amount of organic pollutants that are difficult to degrade, such as white foam, has increased, and the water surface has been seriously polluted by garbage

At present, most of the cleaning methods for floating garbage on the water surface are cleaning boats or manual cleaning, which is time-consuming and labor-intensive, and is not suitable for narrow waters, and it is difficult to achieve long-term regular cleaning.

At the same time, at this stage, my country's water purification technology in lakes is still immature, and it is urgent to make more use of the self-purification ability of lakes to improve water quality, and to deal with the problem of polluted water bodies.
