A method for repairing aquaculture water body with deformed floating bed for solidifying bacteria and deformed floating bed

Abstract

The invention discloses an aquatic culture water body restoration method using bacteria fixing of a deformation floating bed and the deformation floating bed. The aquatic culture water body restoration method comprises the following steps of using a hard water impermeable separating plate to circle and separate an independent water surface at the water surface, wherein the separating plate is of a structure capable of adjusting the circling and separating area; then, feeding a light-weight biological ceramsite filter material into the circling and separating space of the separating plate to form a self-floating type floating bed; spraying a water purifying microbial preparation to the surface of the floating bed, and fixing microorganisms to form a biological membrane; after the membrane is successfully hanged, adjusting the separating plate to increase the circling and separating area, and continuously restoring a water body. The aquatic culture water body restoration method has the beneficial effects that the advantages of high targeting property, high efficiency and high speed in a microbial restoration technique are maintained, and the problem of poor stability and sustainability in the water purifying process by the bactericide is effectively solved; for the bacteria fixing of the deformation floating bed, the floating bed has small area and large thickness in the early period of membrane hanging, and the biological membrane hanging is convenient; after the membrane is successfully hanged, the floating bed has large water contact area and small thickness, the transfer drag of pollutants in the floating bed is reduced, and the water purifying effect is obviously improved; the influence on the movement space of fishes is avoided.

Description

technical field [0001] The invention relates to the technical field of water body purification in aquaculture, in particular to an aquaculture water body restoration method for bacteria-solidifying aquaculture in a deformed floating bed. Background technique [0002] The massive discharge of aquaculture wastewater can easily lead to aggravated eutrophication of the receiving water body, and its treatment technologies mainly include circulating water industrial treatment and bioremediation technology. [0003] At present, most foreign aquaculture uses the industrialized farming method of circulating water. For example, in some developed countries such as the United States, Germany, Denmark and Japan, in the 1960s, industrialized aquaculture with circulating water was carried out. Wastewater can basically meet the reuse standard after treatment. Due to the high one-time investment and operating costs of this model, there is great resistance to popularization in my country. ...

Problems solved by technology

[0005] The technical problem to be solved by the present invention is to provide a method for repairing aquaculture water body using a deformed floating bed to solidify bacteria, which not only retains the advantages of high targeting, high efficiency and quickness of microbial repair technology, but also effectively solves the problem of poor stability and persistence of bacterial agent purified water. Difficult problem, and deformation of the floating bed solid bacteria, small area and large thickness of the floating bed in the early stage of film formation, which is conducive to biological film formation. After successful film formation, the floating bed has a large area of ​​contact with the water surface and small thickness, and the mass transfer resistance of pollutants in the floating bed is reduced. Purified water The effect is significantly improved
