Abstract

A method for preparing a three-dimensional floating bed used for purifying eutrophic water source is characterized in that the three-dimensional floating bed made of mao bamboo is divided into an upper water surface plant growing area and a lower underwater artificial medium area; in warmer seasons, in the plant growing area, a nylon net is spread on the floating bed for growing water spinach; incolder seasons, in the plant growing area, apart from spreading the nylon net on the floating bed, a piece of non-woven fabrics is also paved for growing ryegrass; the framework of the three-dimensional floating bed consists of mao bamboo pieces with diameters ranging from 6-8 cm, mao bamboo pieces with diameters ranging from 2-3 cm, nylon ropes and elastic fillers; and in the artificial medium area, the elastic fillers are stringed by the nylon ropes and then fixed on the mao bamboo pieces at an upper sash and a lower sash of the three-dimensional floating bed. The method has the advantages that the floating bed has a simple structure, is convenient to prepare, uses easily-accessible raw materials, has low cost, can satisfy the four-season growing requirement, has great buoyancy and achieves good effect in treating eutrophic water body; and the three-dimensional floating bed can lead to the harvest of a certain amount of agricultural byproducts and is favorable for generalization.

Description

technical field

[0001] The invention relates to a treatment method for purifying polluted drinking water sources, in particular to a method for manufacturing a three-dimensional floating bed for purifying eutrophic water sources. Background technique

[0002] Before the present invention, there are many existing methods for purifying eutrophic water bodies by using floating bed plants. According to patent search, there are similar patents at home and abroad, such as the three-dimensional ecological floating bed designed by Li Xianning, which uses biodiversity to purify water quality, but the process is complicated and difficult to operate; another example is an aquatic plant floating island designed by Li Qiang. The carrier bed built by the community realizes the rapid formation of the floating island community of aquatic plants in the water body, but the stability is not enough, and it is only suitable for inland waters with moderate and no waves. In addition, from other p...

Embodiment Construction

[0010] The manufacturing method of the three-dimensional floating bed plant is completed according to the following steps:

[0011] (1) Three-dimensional floating bed frame. The overall frame of the floating bed is formed by nylon ropes 8 fixing moso bamboos of different diameters. The upper part of the floating bed is 1.5m wide and 4.5m long. Two moso bamboos 2 with a diameter of 6 to 8 cm are used as the frame in the length direction of the floating bed in the length direction, and the interval between the two moso bamboos 2 is 1.5 m. Moso bamboos 3 with a length of 1.5 m and a diameter of 2 to 3 cm are arranged every 0.5 m along the length direction. Two moso bamboos 3 with a length of 4.5 m and a diameter of 2 to 3 cm are arranged every 0.5 m along the width direction, thus forming a grid of 0.5×0.5 m. Each moso bamboo is tied up with nylon rope 8 at joint and intersection. The size and structure of the lower part of the floating bed are the same as that of the upper p...
