Embodiment 1

[0047] The front sectional view of the mycorrhized ecological floating bed of the present invention is as follows figure 1 As shown, it includes a floating bed floating body 3, five planting holes 31 are arranged on the floating bed floating body 3, a planting basket 4 is placed in each planting hole 31, and a nylon filter membrane with a pore size of 0.45 μm is provided on the lower side and bottom of the planting basket 4 inner wall 43. The nylon filter membrane 43 is installed at a height of 5 cm in the planting basket 4, and the planting basket 4 is filled with a matrix and planted with aquatic plants 5 that have been inoculated with AMF. The bottom of the planting basket 4 is provided with a biochar-vermiculite layer 46 with a thickness of 5 cm. The biochar-vermiculite layer is prepared from biochar and vermiculite at a mass ratio of 1:10. The biochar is made of rice straw in an oxygen-isolated environment. It is obtained by passing through a 2mm sieve after high-temperat...

Abstract

The invention discloses a mycorrhizal ecological floating bed suitable for water purification and landscaping of small lakes. The mycorrhizal ecological floating bed comprises a floating bed floatingbody and a plurality of planting baskets, a plurality of planting holes are formed in the floating bed floating body, the planting baskets are placed in the planting holes in the floating bed floatingbody, nylon filter membranes with the pore diameter of 0.45 micron are arranged on the lower sides and the bottoms of the inner walls of the planting baskets, and the planting baskets are filled witha matrix and planted with aquatic plants inoculated with AMF. According to the mycorrhizal ecological floating bed provided by the invention, the purification capacity of aquatic plants to sewage isenhanced by utilizing AMF, the formation of mycorrhizal symbionts at the roots of the aquatic plants is promoted by utilizing the drop reoxygenation of a fountain and the interception effect of the 0.45-micron nylon filter membrane, and the sewage purification efficiency is effectively improved.

Description

technical field [0001] The invention belongs to the technical field of water, waste water, sewage or sludge treatment, and in particular relates to a mycorrhized ecological floating bed suitable for water purification and landscaping of small lakes. Background technique [0002] Ecological floating bed, also known as artificial floating bed or ecological floating island, uses soilless cultivation technology and uses polymer materials as a carrier to plant higher aquatic plants or improved terrestrial plants on the water surface of eutrophic water bodies, through the absorption of plant roots , enrichment, and the decomposition and mineralization of pollutants by root microorganisms, reduce the nitrogen, phosphorus and other nutrients in eutrophic water bodies, and achieve the effect of inhibiting the growth of algae and purifying water quality. As an in-situ water restoration technology with good treatment effect and low operation and maintenance costs, ecological floating b...
