Embodiment Construction

[0024] The present invention will be further described below in conjunction with examples, but the present invention is not limited to these examples.

[0025] Floating bed settings are attached image 3 As shown, in the fish pond, an ecological floating bed is arranged along the fish pond. The short side of the ecological floating bed is close to the pond bank, and is fixed along the shore by four sets of nylon ropes on land-based stakes. The short side of the ecological floating bed is designed to be close to the shore, which can expand the area of ​​the floating bed area and increase the planting area.

[0026] as attached figure 1 As shown, the ecological floating bed includes a rectangular main frame 1 surrounded by PVC water supply pipes and PVC elbows, the size of the inner frame is 180cm×120cm, and the pipe body diameter of the PVC pipe is 4cm. Two PS extruded boards 2 arranged side by side are fixed in the main frame 1 by nylon cable ties 3 . The size of a single P...

Abstract

The invention provides a method for purifying water quality by using pennisetum purpureum and an ecological floating bed applying the method. The pennisetum purpureum is planted on the ecological floating bed, and is used for absorbing, adsorbing, retaining and degrading contaminant through growth, so as to realize the purification of water quality. The method specifically comprises the steps of winding the stem base of a pennisetum purpureum cutting with a sponge bar absorbing enough water, fixing in a flower pot, placing the flower pot with plants in planting holes distributed along the water level of an water edge through a pot transferring device, when the pennisetum purpureum grows to 1 to 1.3m in height, reserving stubble with the length of 5 to 6cm and cradling. The ecological floating bed designed for the method consists of PVC (polyvinyl chloride) pipes and PS extruded sheets, and has the advantages of being wind and wave-resistant, antioxidant, extrusion resistant, long in service life, low-cost and the like. According to the method provided by the invention, the characteristics of large biomass, quick growth, developed root systems, cradle resistance and the like, and feeding and electricity generation functions of the pennisetum purpureum are utilized, and by applying the pennisetum purpureum into an ecological floating bed system, not only can water quality be effectively purified, but also economic output can be realized, so that the method is worthy of large-scale promotion.

Description

technical field [0001] The invention relates to the technical field of water purification, in particular to a method for purifying water by using elephant grass and an ecological floating bed using the method. Background technique [0002] The ecological floating bed uses a floating board that can float on the water surface and can bear a large weight as a carrier, and transplants aquatic plants or wet plants with water purification effect onto the water surface. During the growth process, plants can degrade or remove N, P, organic pollutants and other pollutants in the water body by absorbing, adsorbing, intercepting and affecting microorganisms, which can not only purify water quality, but also create a benign water environment. Ecological environment, such as habitats and breeding and spawning areas for fish, plankton, insects, etc. At the same time, through the water planting of economic plants or landscape plants, water purification, economic utilization and landscapin...
