Specifically, former to using hydro powered controlled circulation biology in situ regenerating unit to carry out water environment pollution in conjunction with Fig. 1
The method of position processing illustrates：
The main working region of hydro powered controlled circulation biology in situ regenerating unit, including concatenated interior cycle in two spaces,
Liquid and its exterior space liquid are circulated in wherein the second guide shell 9, generate cycle, the first guide shell 3 in higher level
Interior liquid and its exterior space liquid carry out circulatory flow, generate in subordinate and recycle.
The liquid circulation energy that higher level's internal circulation flow and subordinate's internal circulation flow generate pushes the first driving turbine second
Driving wheel move, realize hydro powered without exogenous power input can starter work, reached energy saving mesh
's.
Simultaneously according to water movement direction, the inner space of the first guide shell 3 and the second guide shell 9 constitutes up-flow area, with
Its corresponding exterior space is the areas Jiang Liu.It is separation with cone cylinder 7, is referred to as upper layer up-flow area I and upper layer drop stream in upper layer
Area II；It is referred to as up-flow area III of lower layer and the areas Jiang Liu of lower layer IV in lower layer；Lower layer's connecting plate and mud face institute clip space are muddy water
Mixed zone V.
According to water environment feature, the guide shell internal environment where upper layer up-flow area I and up-flow area of lower layer III is mainly
Guide shell external environment where aerobic environment, the upper layer areas Jiang Liu II and the areas Jiang Liu of lower layer IV is mainly anoxic and anaerobic environment.
Aeration pump 14 is started, load air-flow enters through lower part annulus aerator 19 dominates flow cartridge 1, and lower layer is caused to flow up area III
Interior liquid gas holdup is higher, and mixed liquor density is small, and liquid gas holdup is small in the areas Jiang Liu of lower layer IV, and mixed liquor density is big.By

Enter in upper layer up-flow area I afterwards, is recycled to set up in higher level.Circulating water flow drives respectively in circulating water flow and subordinate in higher level
It moves this grade of driving wheel and rotates and formed resultant force, and then central shaft 12 is driven to rotate, the rotation of central shaft 12, which drives, is connected to its bottom
Stirring mechanism 20 move, the bed mud on the fully mud face surface layer of agitation water environment of stirring mechanism 20 makes its suspend, and under
In grade under the entrainment effect effect of circulating water flow, the bed mud that suspension is got up is made to be forced to participate in follow in cycle and subordinate in higher level
Ring.
The bed mud that circulating water flow entrainment suspension is got up in the interior cycle of higher level and subordinate constantly circulates, when suspension is got up
Bed mud flow alternately through up-flow area III of lower layer and when the up-flow area I of upper layer by consumingly action of turbulent flow, keep background in bed mud organic
Object generates secondary dissolving and effect of mass transmitting, realizes the exchange of the organic pollution of bed mud.
It, only need to be by stabilizer blade from fixed mud face after carrying out repair process to a certain local area ecological of water environment using the above method
Go out, pontoon is pushed, by hydro powered controlled circulation biology in situ regenerating unit dystopy to new region, hydro powered controlled circulation
Biology in situ regenerating unit carries out water environment restoration of the ecosystem in new region.

Anaerobic environment realizes space superimposed layer A/O and A2/ O gradient series connection acts on, and flows alternately through anaerobism, anoxic and aerobic environment, has
Effect strengthens the biodegradation of indigenous microorganism in bed mud, reaches bed mud life synchronous with nitrogen with background organic matter in water body
Object is degraded and is repaired, and realizes the organic pollution bio-regeneration of bed mud.
In short, the core of water environment pollution in-situ treatment method is to construct cycle in the concatenated two-stage of space superimposed layer,
It is to be recycled in cycle and higher level in subordinate respectively.Air-flow is loaded in subordinate and is recycled first, is sequentially driven under the effect of air lift principle
It is recycled in dynamic subordinate and higher level, realizes the spatially series connection of two stage cycle gradient and level driving effect.At the same time, in waterpower
Cycle generates driving force when flowing through up-flow area's two-stage drive wheel, drives stirring mechanism agitation sediments that it is made to suspend, hangs
Floating sediments participate in recycling in two-stage under the entrainment of circulating water flow in subordinate, flow alternately through anaerobism, anoxic and aerobic environment,
Realize space superimposed layer A/O and A2/ O gradient series connection acts on, and the biodegradation of indigenous microorganism, reaches in efficient hardening bed mud
To the purpose of the in-situ synchronization degradation of background organic matter in bed mud and water body and nitrogen, the biological prosthetic of organic pollution is realized.
Embodiment described above is only to express embodiments of the present invention, the description thereof is more specific and detailed, but can not
Therefore it is interpreted as the limitation to the scope of the claims of the present invention.It should be pointed out that those skilled in the art,
Under the premise of not departing from present inventive concept, several deformations, same replacement can also be made, improved etc., these belong to the present invention
