Activated carbon and aeration coupled algal inhibition type biological floating bed

Abstract

The invention discloses an activated carbon and aeration coupled algal inhibition type biological floating bed. According to the technical scheme, the floating bed is characterized in that the floating bed comprises a floating bed module and an aeration pipe; an air conveying pipe is connected between a control box and the aeration pipe, the lower end of the floating bed module is connected with a combined filler through a rope, and submerged plants are planted at the upper end of the floating bed module; the left side and the right side of the aeration pipe are connected with side air supply pipes respectively, the side air supply pipes are vertically arranged, the upper ends of the side air supply pipes are connected with small floating balls through pull ropes, the outer sides of the side air supply pipes are connected with a plurality of branch air pipes, a nutrient soil layer is arranged in the plant planting bed, and an isolation layer is arranged at the upper end of the nutrient soil layer. The roots of the submerged plants are arranged in the nutrient soil layer, and the activated carbon adsorption layer is arranged at the lower end of the nutrient soil layer. According to the invention, the problems that an existing biological floating bed is poor in aeration effect, and organic matters such as nitrogen, nitrogen and phosphorus are difficult to effectively clean are solved.

Description

technical field [0001] The invention relates to the technical field of biological floating beds, in particular to an algae-inhibiting biological floating bed coupled with activated carbon and aeration. Background technique [0002] With the rapid development of my country's economy and the vigorous advancement of urbanization, the problem of eutrophication of water bodies is becoming more and more serious. After a large amount of wastewater rich in organic matter is discharged into the water body, the number of microorganisms in the water body increases sharply, and the dissolved oxygen in the water body drops sharply under the action of aerobic bacteria, resulting in an anaerobic environment in the water body, which eventually makes the water body black and smelly. Ecological floating beds are currently the solution to this problem. The more effective method for the problem; the ecological floating bed takes aquatic plants as the main body, uses soilless cultivation technol...
