Mycorrhizal ecological floating bed suitable for water purification and landscaping of small lakes

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...

AI Technical Summary

Problems solved by technology

[0006] The present invention aims to solve the problems of poor adaptability and low treatment efficiency of the existing ecological floating bed technology. By adding AMF bacterial agent in the matrix around the root system of the floating bed plants, an AMF-plant symbiosis system is generated to complete the mycorrhization of the floating bed plants. AMF enhances the tolerance of floating bed plants to pollutants, strengthens the sewage purification function of ecological floating beds and the stability of the system
