Riverway channel water quality biologically-intensifying device and application thereof

Abstract

The invention provides a riverway channel water quality biologically-intensifying device and application thereof, belonging to the field of water treatment. The riverway channel water quality biologically-intensifying device comprises a transferring shaft and a filler area, wherein with the transferring shaft is positioned in the center of the riverway channel water quality biologically-intensifying device; the filler area encloses the transferring shaft. The riverway channel water quality biologically-intensifying device is characterized in that an upper fixed plate (3), a lower fixed plate and the transferring shaft (1) are integrated into a whole by taking the transferring shaft (1) as a center; an impeller (5) is fixed on the lower fixed plate; the filler area (4) is divided into fourregions through a grating sieve mesh (6), and biological fillers are filled in the regions. The integral riverway channel water quality biologically-intensifying device is driven to move by taking water flows as a driving force when being applied to the treatment of riverway channel water bodies, prevents the fillers from washing away by combining the fixed biological fillers with suspension fillers, can achieve the effective elimination and the synchrous denitrification of COD (Chemical Oxygen Demand), achieves the moving bed effect and also greatly enhances the mass transfer rate of nutrient substances and dissolved oxygen; and in addition, the riverway channel water quality biologically-intensifying device can carry out the treatment aiming at the pollution conditions of different water layers of riverway channels and also has the advantages of energy saving, environmental protection, low acquisition cost and operation cost, and the like.

Description

technical field

[0001] The invention relates to a bio-augmentation device, more specifically to a bio-augmentation device for water quality in a river channel and ditch and its application. Background technique

[0002] The river ecosystem is a complex system, which is composed of subsystems such as riparian ecosystem, water ecosystem, wetland and swamp ecosystem. The discharge of sewage into the river, excessive water use, crowding of river beaches, deforestation, introduction of alien species, and large-scale damming, reservoir construction, channelization and other water conservancy engineering measures will all damage the health of the river ecosystem. Excessive water use and sewage discharge lead to serious shortage of water or deterioration of water quality, making it difficult for most aquatic organisms to survive, which will lead to the collapse of the river ecosystem. Various water conservancy projects will change the natural landform characteristics, hydrology and ...
