Problems solved by technology

[0004] However, single ecological floating islands have different absorption efficiencies for pollutants due to the fact that aquatic plants have certain requirements for their own growth environment, and the composition of black and odorous water bodies is relatively complex.

Embodiment 2

[0038] In this embodiment, take the black and odorous water body of 60L of closed water body as an example, the water quality of the black and odorous water body is 95mg / L of COD, the water surface coverage area of ​​the floating plate is 0.12m2, the water surface coverage is 45.3%, and the ecological floating island is planted with emerging water Plants 1 Cymbidium, Calamus, Iris, the planting density ratio is 1:1:1 and the coverage rate is 20%, select the substrate 2 ceramsite: the ratio of volcanic stone is 1:1.

[0039] In this example, after 5 days, 10 days, 15 days, 20 days, and 30 days, the water quality content of COD was measured, and the results showed that COD dropped to 65mg / L, 42mg / L, 37mg / L, 30mg / L, 23mg / L respectively L.

[0040]To further expand, in this embodiment, the strip plate 10 adopts a structure with an adjustable mutual interval. Through such an arrangement, the strip plate 10 can be adjusted to a suitable distance according to the actual size of the p...

Abstract

The invention discloses an ecological floating island device which comprises a planting basket module, a floating plate module and an adsorption module. The planting basket module is composed of an upper frame and a lower frame which are used for fixing plants, and the upper frame is arranged to be strip-shaped plates which are arranged in a criss-cross mode. The lower frame is used for being filled with a matrix, a plurality of containing grooves are formed in the bottom of the lower frame, and the lower frame achieves the water permeable effect through the containing grooves; the adsorption module comprises modified cocoanut active charcoal and hanging filler. Compared with the prior art, the ecological floating island device provided by the invention has the beneficial effects that the modified cocoanut active charcoal is added, and mesopores and oxygen-containing functional groups on the surface of the modified cocoanut active charcoal are increased, namely, adsorption sites are increased, so that a large number of attachment sites are provided for attachment of microorganisms, and the adsorption of pollutants is facilitated; the coupled matrix and filler are more beneficial to the growth of plants and the action of microorganisms, and the purification effect of the ecological floating island on pollutants is accelerated.

Description

technical field [0001] The invention relates to the technical field of water body treatment, in particular to an ecological floating island device. Background technique [0002] With the rapid development of the urban economy, the scale of the city is growing day by day, while the construction of urban environmental infrastructure is lagging behind, and the amount of sewage discharge has increased significantly, resulting in excessive pollutant loads, resulting in the deterioration of the surface water quality in the area, resulting in seasonal or year-round black water bodies. Smelly. At present, these black and odorous water bodies are considered to be a prominent problem of water environment and urban pollution, because they not only damage the ecosystem, such as causing river pollution, lake pollution, etc., but also bring huge losses to residents' productivity, life and health, etc. . [0003] Ecological floating islands have been proven to be a more efficient and con...
