Small-fall type low-energy-consumption jet flow oxygenation aeration device

Abstract

The invention belongs to the technical field of water treatment devices, and particularly relates to a small-fall type low-energy-consumption jet flow oxygenation aeration device which comprises an aeration tank, a water pump, a first pipe, an aeration pipe, an air blower, a lifting rod and a second pipe. The aeration pipe is mounted at the top of the aeration tank, and the bottom of the aeration pipe is higher than the water surface in the aeration tank. Sewage at the bottom of the aeration tank is lifted into the aeration pipe above the water surface through the water pump, so that the sewage flowing into the aeration pipe is fully combined with air sucked under the action of the air blower, and the sewage mixed with the air is accelerated to flow downwards to impact the inside of a polluted water body; and therefore, sewage mixed with air is quickly diffused in the polluted water body, further, oxygen in the polluted water body is distributed more uniformly, and the purification efficiency of the polluted water body is improved.

Description

technical field [0001] The invention belongs to the technical field of water treatment devices, in particular to a small-drop low-energy jet aeration device for increasing oxygen. Background technique [0002] In recent years, with the rapid development of modern economy and the rapid expansion of population, the problem of environmental pollution has become increasingly serious. Among them, the problem of water pollution is particularly prominent, and in water pollution, the most serious problem is the eutrophication of water bodies. The eutrophication of the water body leads to the abnormal proliferation of algae, forming what people often call "water bloom" and "red tide", which makes the water body smelly and unpleasant, and the transparency decreases, and the lack of oxygen will also lead to the death of a large number of aquatic organisms, resulting in The vicious circle of environmental ecology leads to the collapse of the ecosystem. At present, engineering measures...

Problems solved by technology

[0005] In order to make up for the deficiencies of the existing technology, when the existing aeration and oxygenation device is applied to the aeration and purification of polluted water treatment, due to the small kinetic energy of the outflowing sewage mixed with air, the diffusion range of the sewage mixed with air is relatively small. Smaller, so the oxygen distribution inside the polluted water body is uneven, which affects the purification of the polluted water body; a small drop type low-energy jet aeration aeration device proposed by the present invention
