The invention belongs to the technical field of water ecological restoration, and particularly relates to a
photocatalysis-
biological membrane synergistic type ecological floating
bed system based on
solar energy driving and application of the
photocatalysis-
biological membrane synergistic type ecological floating
bed system. The ecological floating
bed system comprises a floating bed module, a
biofilm carrier module, a
photocatalysis module, an
aeration module and a power supply module. The carbon
fiber substrate, the photocatalyst and the UV-
LED lamp irradiation structure are adopted, all-day work is achieved through
sunlight in the
daytime and UV-LED lamps at night, the photocatalyst loaded on the carbon
fiber substrate is activated, oxidation groups are generated, degradation of organic pollutants is promoted,
algae are efficiently controlled, and pollutants such as algal
toxin are degraded.
Oxygen supply of the
aeration module is enhanced, and the
biological membrane nitration reaction is promoted. The composite filler in the planting basket adopts the
layout of ceramsite-
volcanic rock-
manganese ore, so that the functions of physical adsorption,
ion exchange and
electron transfer are synchronously realized; after the composite filler adsorbs pollutants, in-situ regeneration can be realized through
aeration disturbance and
microbial metabolism; all the modules cooperate to improve the
pollutant removal efficiency.
