Problems solved by technology

[0004] The purpose of the present invention is to provide a stable and more effective composite three-dimensional biological floating bed for removing nutrients such as N and P, which is composed of cheap and easily available materials and plants, and solves the problem that polystyrene foam is mostly used in current floating beds. Plates bring secondary pollution to water

Embodiment 1

[0015] Embodiment 1: select bamboos 1 longer than 2 meters to be connected into a quadrilateral, as a floating bed for planting on water, fixed with bamboos around, each size 2m × 2m, by 2 to 4 such bamboo beds to form a grid-like three-dimensional frame , and set two floating buckets 2 on both sides. Float the floating bed in the center of the water. Plant canna 3 and fix it on the uppermost floating bed, with 5×5 plants; the spacing is usually about 50cm and use thin bamboo in the middle to fix the plants on it, and keep the spacing between the plants. The lower hanging elastic material 4 is about 1m long; the bottom is fixed with stones 5 to prevent the floating bed from drifting. The floating bed is placed in the center of the pond or reservoir area, and is applied to a water depth of more than 2.5m: the dead branches are removed according to the season, and the floating bed is replaced regularly (about 1-2 years).

Embodiment 2

[0016] Example 2: Select 1.6-meter-long bamboos 1 to be connected into a quadrangle, as a floating bed for planting on water, fixed with bamboos around them, each size is 1.5m × 1.5m, and a grid-shaped three-dimensional frame is formed by 2 such bamboo beds , and set two floating buckets 2 on both sides. Float the floating bed in the center of the water. The water spinach 3 plants are fixed on the top floating bed, 6×6; the spacing is usually about 30cm, and the plants are fixed on it with thin bamboos in the middle, and the plants keep the spacing. The lower hanging elastic material polyethylene 4 is about 1m long; the bottom is fixed with iron blocks 5 to prevent the floating bed from drifting. The floating bed is placed in the center of the pond or reservoir area, and is applied to a water depth of 2.5m to 5m; the plants are harvested regularly according to the season, and the floating bed is replaced regularly (about 1-2 years).

Embodiment 3

[0017] Embodiment 3: select 1 meter long bamboo 1 to be connected into a quadrangle, as a floating bed for planting on the water, fixed with bamboo around, each size 1m × 1m, constitute a grid-like three-dimensional frame by 4 such bamboo beds, both sides. Set up two floating buckets 2. Float the floating bed in the center of the water. The cress 3 plants are fixed on the top floating bed, 4×4; the spacing is usually about 20cm, and thin bamboo is used in the middle to fix the plants on it, and the plants keep the spacing. The lower hanging elastic material polypropylene 4 is about 2m long; the bottom is fixed with iron blocks 5 to prevent the floating bed from drifting. The floating bed is placed in the center of the pond or reservoir area, and is applied to a water depth of 2.5m to 5m; the plants are harvested regularly according to the season, and the floating bed is replaced every year.

Abstract

The composite stereo biological hover bed has stereo frame of bamboo with upper layer of nodes for setting plant, floated barrels on two side, suspended elastic string material and fixers in the lower layer. In the hover bed, aquatic vegetable and ornamental plant, such as water celery, canna, etc., with fast growth and developed root system are planted. The present invention is suitable for pond and reservoir with deeply polluted water, and has high N and P eliminating effect, and no secondary pollution.

Description

1. Technical field [0001] The present invention relates to a biological floating bed. 2. Background technology [0002] The application of floating bed technology began in the 1970s, and there are many studies in Japan and other countries. It has been reported that the water surface floating bed is soilless to grow rice, flowers and other crops to treat wastewater (Wu Weiming, Song Liangfu, Jin Ganyu, et al. Research on soilless cultivation of canna in fish ponds [ J].Journal of Applied and Environmental Biology, 2000, 6(3): 206-210; Ma Lishan, Luo Yongming, Wu Longhua, et al.
