A bubble plume oxygenation water quality restoration device and method

Abstract

The invention discloses a bubble plume oxygenation water quality restoration device and method. The bubble plume oxygenation water quality restoration device is provided with a switchable gas source and an oxygen conveying pipe and comprises a supporting rod, a gas distribution tray, an annular hole, an oxygen inlet, a gas distribution pipe, a tee pipe, micropore aeration pipes on six corners of the device, micropore aeration pipe orifices, a nano rubber macropore aeration pipe, a macropore aeration pipe orifice, a suspender upper welding tray, a suspender lower welding tray, a firm metal suspender, a fixed bolt and a supporting base. The bubble plume oxygenation water quality restoration device is applicable to typical shallow and deep lakes, and according to different structural characteristics of the shallow and deep lakes, the air source is reasonably used; by reasonably switching a water mixed oxygenation function and a hypolimnion direct injection oxygenation function, the treatment is carried out according to the circumstance, and the water quality in the lakes can be efficiently and economically restored; the bubble plume oxygenation water quality restoration device does not need a power supply at the bottom of the lake and is not required to be electrified in the water, so that the operation and construction difficulty can be greatly alleviated, and the generalization performance is high.

Description

technical field [0001] The invention belongs to the technical field of water quality restoration, and relates to a treatment device for water quality deterioration of lakes and rivers, in particular to a device for repairing water quality of shallow lakes and deep lakes, enhancing the pollution load capacity of shallow lakes and rivers, and improving deep water lakes and reservoirs. Oxygen environment, water quality remediation method of air bubble plume oxygenation to control phosphorus release from lake sediment. Background technique [0002] At present, shallow lakes are a kind of relatively fragile ecosystem. The material exchange between the lake water and the sediment is strong, the deposition is relatively slow, and it has a low pollution load capacity and is sensitive to pollution responses. It is one of the water bodies that are prone to eutrophication. one. However, deep-water lakes are stratified in summer and mixed in winter, have complex structures, slow pollut...

Problems solved by technology

[0005] In order to solve the shortcomings of the traditional method for increasing oxygen in deep-water lakes and the method for increasing oxygen in traditional shallow-water lakes, the present invention invents a method that is suitable for both deep-water lakes and shallow-water lakes. At the same time, it has high feasibility, low implementation risk, flexible maneuverability, and improved lake water quality restoration. A kind of bubble plume oxygenation water quality restoration device and method is provided to solve the technical problems with good effect
