In-situ ecological running water water-purification device

Abstract

The invention relates to an in-situ ecological running water water-purification device including a circulating running water device, a micro-nano aeration device and a negative ion generator. The micro-nano aeration device includes a shunt, at least one dissolved gas tank and a double-suction pump from up to down successively; the tail end of a water inlet of the double-suction pump is provided with a gas inlet, and the gas inlet of the double-suction pump communicates with the external atmosphere through a gas inlet pipe; a water inlet of the shunt is connected with a water outlet of the double-suction pump; at least two water outlets are arranged at the top of the shunt, at least one water outlet of the shunt is connected with the dissolved gas tank through a water inlet of the dissolvedgas tank; at least one group of turbulent flow blades is arranged at the water inlet of the dissolved gas tank and inside the dissolved gas tank; a venturi tube is arranged at a position of a water outlet at the bottom of the dissolved gas tank, and a liquid in the dissolved gas tank is discharged into a water body through the venturi tube. The device can quickly realize three-dimensional circulation convection of the water body, and uniform high-density micro-nano bubbles are generated to promote oxygen dissolving and purify the water quality.

Description

technical field [0001] The invention relates to an ecological running water device, in particular to a multifunctional fully automatic in-situ ecological running water device. Background technique [0002] In recent years, with the rapid economic growth and the multiple pollution of industrial sewage, agricultural sewage and domestic sewage, the problem of water pollution in our country is also becoming more and more serious. Especially at present, many large cities and industrial areas and cities are built in riverside or lakeside areas, a large amount of untreated wastewater enters the water body, and most of the rivers and lakes are in different degrees of eutrophication. [0003] Eutrophication of water body, the loss of balance in the distribution of species in the water ecosystem, changes in the number and types of biological populations, and the proliferation of aquatic organisms, especially planktonic algae, form algal blooms. The dissolved oxygen content in the wat...

Problems solved by technology

[0005] CN101327988A discloses a method consisting of buoys, inner pipes, outer pipes and water separators, which integrates the functions of aeration, filtration and biochemical treatment, but the filtration function of this method uses materials such as activated carbon and porous glass fiber, and maintenance and maintenance during long-term use The replacement process is cumbersome, and the solar-driven impeller rotates and lifts a small amount of water, and it takes a long time to apply it in a large area of ​​water

CN106365333A discloses a fully automatic solar water treatment system comprising a water sample detection device, an aerator head, an ultrasonic probe and an impeller, which can realize the functions of water body oxygenation and ultrasonic algae killing. The device also has low power and processing time Longer wait is not enough
