Mixed oxygenate-microorganism immobilization biological enhanced artificial floating island

Abstract

The invention discloses a mixed oxygenate-microorganism immobilization biological enhanced artificial floating island which comprises a photovoltaic water pump system, a water flow raising system, a Venturi gas inlet system, an upper floating body and a lower floating body, wherein the upper floating body floats on water; the Venturi gas inlet system comprises a longitudinally arranged Venturi pipe with openings formed in the two ends and a plurality of gas inlet pipes which is communicated with the throat of the Venturi pipe; an gas inlet hole of each gas inlet pipe is above the water level;the water flow raising system longitudinally penetrates through a floating body; the bottom of the water flow raising system is connected with an upper part straight cylinder of the Venturi pipe; thebottom of a lower part straight cylinder of the Venturi pipe is communicated with a water inlet hole of the photovoltaic water pump system; plants in the upper floating body and the lower floating body have the purification effect on the water quality; pollutants such as nitrogen, phosphorus and organic matters in water can be effectively degraded through biological membranes; and spherical fillers in the floating body greatly strengthen the adsorption and degradation effect on the pollutants. The mixed oxygenate-microorganism immobilization biological enhanced artificial floating island provided by the invention can greenly run with low carbon, can economically and efficiently improve the water quality of water bodies in shallow river lake and reservoirs in situ without power consumptionand controls eutrophication of the water body.

Description

technical field [0001] The invention relates to a mixed oxygenation-microbial immobilization bio-enhanced artificial floating island, which is suitable for various lakes, reservoirs, landscape water and other water bodies. Background technique [0002] In recent years, various ponds, artificial lakes, artificial rivers and other landscape water bodies have been widely used in parks, residential quarters, hotels and other places. Landscape water is mostly static or closed slow-flowing water bodies with poor fluidity, and the general water area is relatively small, so the water environment capacity is small and the self-purification ability of water bodies is low. Some of the water sources of landscape water use tap water, which makes the water body lack a whole biological chain, so the self-purification ability is extremely low. Although some landscape water is diverted from natural rivers or lakes, due to the serious pollution of urban water sources and the high content of ...

Problems solved by technology

But the shortcoming of this invention is that most of the time, the upper layer floating island covers the sunlight of the lower layer plants, and the space between the upper layer and the lower layer is all wasted.

[0005] Ordinary biological carrier adsorption and purification of artificial floating islands requires sufficient oxygen, while the dissolved oxygen content in polluted water is low, and the existing artificial floating island technology can only purify the affected area around it, while the waters near the shore are difficult to clean. be purified
