Composition and application method of aeration device

Abstract

The invention relates to a composition and an application method of an aeration device, in particular to an inflatable aeration machine which mainly consists of a mechanical device for producing compressed air, a floating supporting structure, an aeration cushion and a box-type structure being partially opened; the box-type structure is provided with a machine for producing the compressed air and is supported by the floating supporting structure to be floated on the water surface; a plurality of aeration cushions stay on the same plane to be installed inside the box-type structure, the aeration cushions are connected with each other and are connected with a main air pipe and the mechanical device for producing the compressed air through a secondary air pipe; a branch air pipe and an aeration pipe, which stay on the same plane, form an aeration cushion which is fixed by a bracket, and each surface of the box-type structure is separated by a plate being partially opened; the bracket which is connected with the floating supporting structure is adjusted so as to control the depth and the horizontal degree of the plurality of aeration cushions in the water; and the compressed air forms bubbles when passing through the plane of the aeration cushions, a vapor-liquid mixture moves upwards inside the box-type structure so as to aerate the water on the bottom layer. The device is widely used for the fields such as the water aeration, the aquatic culture aeration and the like.

Description

Technical field: [0001] The invention relates to the composition and use method of an aeration and reoxygenation equipment for mixed treatment of gas and liquid, in particular to the equipment and method for raising the lower layer of liquid upwards, entraining and dissolving, and mixing and stirring. Background technique: [0002] At present, the problem of black and odor in urban rivers across the country has become a top priority in urban environmental work. Among the urban river sections, 38% of the water bodies are lower than the V category in the national "Surface Water Environmental Quality Standards". The research on artificial aeration and reoxygenation of river water has been carried out for more than 20 years abroad, and it occupies an important position in water purification. The successful experience of some European and American countries and some test results in our country show that artificial aeration and reoxygenation is an effective engineering measure to ...
