Ecological floating island device for purifying micro-polluted water bodies

Abstract

The invention discloses an ecological floating island device for purifying micro-polluted water bodies. The ecological floating island device is suitable for improvement of the water quality of urban rivers, ecological construction of the artificial lakes in the residential communities, purification of the water of the artificial wetlands and purification and improvement of various micro-pollutedwater bodies and has the functions of adsorption and interception, microbial degradation, aquatic plant absorption and the like towards the pollutants. The ecological floating island device comprisesan upper ecological floating bed, middle connecting devices and a lower China fir crib water treatment reactor. The ecological floating island device is characterized in that the ecological floating island device integrates the advantages of the adsorption filler water purifier and the traditional ecological floating bed on the basis of having the characteristics of the adsorption filler water purifier and the traditional ecological floating bed to form a more systematic structure form; the structure form more effectively utilizes the water body space while enhancing the capability of purifying the pollutants in the water bodies, reduces the construction difficulty and ensures the plant floating bed to be more flexibly applied in the engineering.

Description

technical field [0001] The invention belongs to the technical field of water quality purification, and specifically relates to an integrated ecological floating island device which is applied to urban inland rivers, artificial lakes in residential quarters, artificial wetlands and other slightly polluted waters, and has the functions of adsorption, interception and biological ecological purification of pollutants. Background technique [0002] At present, water quality improvement technologies for urban inland rivers, artificial lakes and other waters can be roughly divided into physical methods, chemical methods, and bioaugmentation methods. The bioaugmentation method mainly adopts aquatic plant technology, aquatic animal technology, and biofilm-based microbial technology. Artificially improve and optimize the water body ecosystem, improve the self-purification ability of the water body, and achieve the purpose of purifying water quality. At this stage, there are many resea...

Problems solved by technology

The single use of the two water treatment facilities failed to make full use of the limited available water body space in the project in some cases

On the one hand, the adsorption packing reactor can be flexibly placed in the water and at the bottom, but the upper water surface has not been fully utilized. Although the water purification effect is guaranteed, it cannot meet the needs of the landscape effect in the project; on the other hand, the ecological floating bed is installed on the water surface. Above, the space below it has not been fully utilized, and it needs to be fixed by piling on the bottom of the river or connected to the shore through a chain. Although the requirements of the engineering landscape are guaranteed, the purification effect on the water quality is not good, and some construction points are High construction requirements

Therefore, the single use of adsorption packing reactor or ecological floating bed to purify water quality in engineering seems to be a fly in the ointment, and it is necessary to invent a water treatment device that combines the advantages of both.
