Modular aerating/oxygenating device

Abstract

The invention discloses a modular aerating/oxygenating device, and belongs to the field of environment protection equipment. The device comprises aerators, a square frame, a gas distribution pipe, gas distribution adapters, counterweights, buoys, an end fixing member, and riggings; multiple aerators are parallelly arranged in the square frame, one end of each aerator is connected to a gas distribution adapter, the gas adapters are connected to the gas distribution pipe, the other end of each aerator is sealed and fixed on the square frame; the counterweights are fixed under the four corners of the square frame through the riggings, and the other end of each rigging is provided with a buoy. The provided device can be used to treat polluted water body in the nature by oxygenating the water body, and is capable of being applied to the aeration system in the industries such as aquaculture, sewage treatment, and the like. The device can be installed in the water, which needs to be oxygenated, or the device can be installed on the bottom of a container containing water to be processed. The installation is simple, and the maintenance and exchanging are both very convenient. The device is composed of a plurality of modules, the combination is flexible, so the device can be used under different occasions, moreover, the production process is simplified due to the modular design, and the cost is very low.

Description

technical field [0001] The invention relates to an aeration device used for sewage treatment, water restoration and aquaculture aeration, in particular to a modular aeration device, which belongs to the field of environmental protection equipment. Background technique [0002] Sewage treatment is an environmental problem that spreads all over the world. Whether in developing countries or developed countries, huge manpower and material resources are invested in the treatment of various types of sewage. Sewage biochemical treatment methods, such as activated sludge method, contact oxidation method, biofilm method, etc., rely on microorganisms in activated sludge to remove pollutants in sewage. These processes need to ensure dissolved oxygen. [0003] Since the 1960s, more and more attention has been paid to the treatment and recovery of polluted water bodies in the natural environment. Countries all over the world have successively researched and developed various new technolo...

Problems solved by technology

Mechanical aeration is generally surface aeration, which is easy to install but has poor aeration performance, such as water wheel aeration, brush aeration, etc.

Blast aeration is composed of fan, gas pipeline and aerator. The aerator has various types such as disc type, tube type and plate type. The aeration performance is higher than that of mechanical aeration. It is generally installed at the bottom of the water or at the bottom of the biochemical tank. , but the construction volume of the gas supply pipeline is large, and it is difficult to install, maintain and replace
