Underwater purifying device

Abstract

The invention discloses an underwater purifying device, and belongs to the field of water treatment. The underwater purifying device comprises a water surface aeration device and a microbial carrier device, wherein the water surface aeration device comprises an air compressor located on the surface of a water body, a magnetic-boosted rotational flow gas diffusion pipe located under the water, a filler barrel unit and a gas inlet pipe, wherein the magnetic-boosted rotational flow gas diffusion pipe comprises a gas inlet, a through hole, a cross-shaped impeller hydrocyclone and mushroom-shaped cutters; the filler barrel unit comprises a barrel body, a filler layer, a porous baffle plate, a buoyancy layer, a porous metal pipe and an aeration pipe; the filler barrel unit is also connected witha double-layer material filter structure; the microbial carrier device is located under water and comprises floating barrels, basalt fiber carriers and concrete precast blocks. According to the underwater purifying device provided by the invention, the concentration of dissolved oxygen in the water body and the indigenous microorganism amount in the water body are increased; meanwhile, heavy metal pollutants in the water body can be effectively removed; efficient and quick purification on underwater pollutants is realized.

Description

technical field [0001] The invention discloses an underwater purification device, which belongs to the field of water treatment. Background technique [0002] For a long time, due to the lack of systematic, collaborative and innovative scientific research on water pollution problems, water pollution prevention and control technology is relatively weak, and most of the closed water bodies are slow-flowing waters, with small environmental capacity and low self-purification ability. Poor, highly susceptible to pollution, resulting in the increasingly serious situation of this type of water pollution has not been fundamentally reversed. [0003] The sources of water pollution mainly come from industrial wastewater, domestic sewage, and wind and sand dust. When the total amount of pollutants entering the water body exceeds the self-purification capacity of the dissolved oxygen content in the water body, the total dissolved oxygen in the water body is quickly consumed, making the...

Problems solved by technology

[0004] The existing urban river treatment technologies in my country mainly include: water exchange and diversion, artificial aeration technology, wetland ecological technology and ecological floating bed technology, etc. Frequent water exchange and water diversion are difficult, and the existing ecological wetland and ecological floating bed technologies are both It needs to occupy a certain amount of shoreline space and water surface space, which brings certain difficulties to urban river water cleaning, river dredging and river management. The above factors have become the bottleneck problems encountered in the river management in our country
