Method for preparing three-dimensional floating bed used for purifying eutrophic water source

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...

Problems solved by technology

However, the existing method of purifying eutrophic water by floating bed plants has the problem of purifying effect in the low water temperature season in winter, that is, the seasonality of plant growth is not considered
