Internal variable pressure autorotation type water body bioremediation device

Abstract

The invention discloses an internal variable pressure autorotation type water body bioremediation device. The invention belongs to the technical field of water body remediation. The internal variablepressure autorotation type water body bioremediation device comprises a column body; the outer end of the column body is fixedly connected with a floating airbag; an inner cavity and an outer ring cavity are formed in the column body; the outer ring cavity is positioned on the outer side of the inner cavity; an inner air vent communicated with the outer ring cavity is formed in the inner wall of the inner cavity; an inner ring plate is rotationally connected into the outer ring cavity; the outer end of the inner ring plate is in contact with the inner wall of the outer ring cavity. According to the invention, the expansion variable-pressure column absorbs moisture automatically to expand, then gradually loses water and shrinks; under the volume change of continuous circulation of expansionand shrinkage, the air pressure in the column body is continuously changed, and under the control of the air pressure, the inner ring plate and a repairing rod continuously rotate in the water body along with the change of the air pressure, so that on one hand, the flowing of a static water body can be accelerated, and on the other hand, the uniform repairing of the water body is realized in a certain area range.

Description

technical field [0001] The invention relates to the technical field of water body restoration, in particular to an internal pressure-variable self-rotating water body bioremediation device. Background technique [0002] Rehabilitation of polluted rivers, lakes and reservoirs is an urgent need for social and economic development and ecological environment construction, especially the pollution control projects along the east route of the South-to-North Water Diversion Project, which have a large volume and a wide area, and it is imminent to find advanced, practical and low-cost technologies. Water pollution in rivers, lakes and reservoirs in my country mainly includes two aspects: nitrogen, phosphorus and other nutrients and organic matter pollution. [0003] Water body restoration refers to the process of restoring the water body to its original ecological function by adopting artificial physical, chemical and biological methods in addition to relying on the self-adaptation,...

Problems solved by technology

[0004] However, water bodies such as rivers, lakes and reservoirs belong to static water ecosystems with extremely small water fluidity. When in-situ restoration methods are used, due to the low fluidity of the water body, it is difficult to restore the water area evenly and fully, so that the entire water area can be repaired. Less efficient and less effective repair
