Problems solved by technology

Currently commonly used peroxides, such as magnesium peroxide (MgO 2 ), calcium peroxide (CaO 2 ) reacts with water to release oxygen (O 2 ) as an oxygen source in water purification, but its reaction product is often a strong alkaline substance, which will affect the pH of the water body, endanger the growth and development of plants and cause secondary pollution

Embodiment 1

[0029] The invention provides an oxygen slow-release generating device for the construction of aquatic plant mycorrhizae, such as figure 1 , figure 2 As shown, a preferred embodiment of the present invention is shown therein. Specifically, the oxygen slow-release generating device includes a floating ball 1 arranged on the water surface and an oxygen slow-release unit arranged on the bottom of the water, and the oxygen slow-release unit is connected with the floating ball 1 through a connecting rope 13, the The oxygen sustained-release unit comprises a base support 10 arranged at the bottom of the water, a lower hemispherical body 8 arranged on the base support 10 and an upper reticular hemispherical body 6 connected with the lower hemispherical body 8 through a sealing thread 7, the upper part The mesh hemispheroid 6 includes an outer metal mesh layer 3, a polytetrafluoroethylene film 4, and an inner metal mesh layer 5 arranged sequentially from the outside to the inside, a...

Embodiment 2

[0044] The present invention also provides a method for constructing aquatic plant mycorrhizae, which mainly uses an oxygen slow-release generating device to provide an aerobic and low-phosphorus environment during the process of constructing and growing aquatic plant mycorrhizae. When the oxygen slow-release generating device is placed in the water body, it can provide an aerobic and low-phosphorus environment for the construction and growth of aquatic plant mycorrhiza. The general principle is: after the lower spherical structure with a base is placed around the root system, the Oxygen slow-release materials react with water to slowly release O 2 , the released O 2 The waterproof and breathable membrane located on the spherical surface is further released to the root system to provide an aerobic environment. The increase in oxygen content in the sediment will inhibit the release of phosphorus in the sediment, thus creating an aerobic and low-phosphorus environment for mycorr...

Abstract

The invention relates to an oxygen slow-release generation device and method for constructing aquatic plant mycorrhizae. The device comprises a floating ball and an oxygen slow-release unit, wherein the floating ball is arranged on the water surface, the oxygen slow-release unit is arranged at the water bottom, is connected with the floating ball through a connecting rope and comprises a base bracket, a lower-part semi-spherical body and an upper-part net-shaped semi-spherical body, the base bracket is arranged at the water bottom, the lower-part semi-spherical body is arranged on the base bracket, the upper-part net-shaped semi-spherical body is in sealed threaded connection with the lower-part semi-spherical body, a water injection hole is formed in the side surface of the lower-part semi-spherical body, the lower-part semi-spherical body is filled with oxygen slow-release bodies, and oxygen saturated water is injected into the lower-part semi-spherical body through the water injection hole. According to the oxygen slow-release generation device, oxygen is slowly released for a long time by virtue of the oxygen slow-release bodies and can be released to the periphery of plant roots without influencing the pH of the environment, and meanwhile, the release of phosphorus in bottom mud is effectively inhibited by virtue of an aerobic environment, so that an aerobic low-phosphorusenvironment is provided for the construction and growth of the aquatic plant mycorrhizae.

Description

technical field [0001] The invention relates to the field of water body restoration, in particular to an oxygen slow-release generating device and method for the construction of aquatic plant mycorrhizae, which are suitable for biological restoration of polluted water bodies. Background technique [0002] my country's water pollution is deteriorating day by day, and the environmental problems of water pollution are particularly prominent, showing a trend of rapid deterioration, such as: eutrophication of surface water bodies, deterioration of groundwater quality, etc. Traditional physical and chemical water body restoration methods are mature in theory and solid in technology, but there are many problems in practical application, such as high cost, technical difficulty, difficult operation, and secondary pollution. In order to avoid these problems, bioremediation technology, which uses plants and microorganisms to purify water bodies, has become a hot spot of water purificat...
