Description
Technical field
The utility model is related to fwaater resources protection and water environment treatment field, specifically a kind of river based on pore water guide
Lake polluted bed mud sludge reduction onsite decontamination apparatus.
Background technology
Bed mud is the important component in important the accumulation library and aquatic ecosystem of dystrophication object, is recycled in regulation and control substance
With ecological process most important effect is played with service.In the case where external source pollution input gradually obtains control, how to have
Effect, which controls endogenous pollution of substrate sludge release, becomes Water Environment In Lakes improvement, and aquatic ecosystem restores basic with bio-diversity conservation
Premise, and current Ecological Civilization Construction and river length of carrying out in an all-round way make the realistic problem that must be faced.
River and lake sediments quality is loose, and muddy water reciprocation is strong, is the active region of pollution release and endogenous control
Key area.Dystopy dredging and covering in situ is mainly taken to solve the problems, such as that endogenous pollution of substrate sludge discharges both at home and abroad, wherein to dredge
Dredge quick, can substantially cut down pollution release iron, but of high cost, the mud amount after dredging is big, moisture content it is high (>90%), dirty
Complicated component is contaminated, subsequent processing is difficult.Covering in situ quickly can inhibit sediment pollution to discharge, and improve water transparency, but take stopgap measures
It does not effect a permanent cure, it is more difficult to cut down bed mud endogenous polyamine total amount, increase lake surface sediments volume instead, reduce the water body depth of water, influence bottom and dwell life
State environment.Therefore, such as how low cost detaches and removes the pollutant in bed mud with the mode of few disturbance ecology environment, is river and lake
Internal loading control obtains long-acting and actual effect key problem in technology.
Pore water is that the important preservation medium of pollutants in sediments and core discharge source.By the high bed mud hole of pollutant concentration
Gap water is detached and is removed, and the total amount and release iron of endogenous pollution of substrate sludge can be effectively cut down.Currently, open both at home and abroad
Some bed muds or the in situ sampling of soil pore water and the technique device of removing.The patent of Publication No. CN 103323290A
A kind of sampler for sediment pore water sampling in rivers or lakes is disclosed, is received by the stainless steel mesh of sampling pipe lower part
Collect pore water, is stored at the conical head of sampling bottom of the tube.The patent of Publication No. CN 105547757A discloses a kind of original
Position Sediment Pore Water is classified active sampler, collects pore water by the ceramic head mounted on different height plastic tube, realizes
Classification actively samples.Application No. is the patent of CN201710096949.X disclose pin-connected panel in situ elution with EKG is electronic cooperates with
The device and method of heavy metal-polluted soil is removed, device includes ekg electrode fixed plate, ekg electrode protection board, ekg electrode, leacheate
The compositions such as permeable tank, heavy metal-polluted soil solution collecting tank, under electric field or so, the pore water after being eluted to farmland soil heavy metals
Carry out collection and discharge in situ.
The utility model people has found by research in the process of implementing the utility model:It is existing based on pore water guide
There are larger deficiencies for riverbed sludge in-situ repairing device or technology:(1) stress to inhibit pore water by dredging or covering in situ
Pollution release, and it is indirect detach from bed mud medium and removes using pore water as pollution sources, therefore, the total amount of endogenous pollution
It cuts down few;(2) pore water sampler with sieve and ceramic head is developed, although pore water can be detached, amount is few, and efficiency is low, and
It is not related to the separation and removal of pollutants in sediments;(3) ekg electrode can take off the agricultural land soil pore water of no overlying water
It removes, but ekg electrode is in direct contact soil, electrode guiding gutter is easy to be blocked by soil particle, and EKG protection boards plug cumbersome, shadow
The sealing performance for ringing device, in addition, the device does not account for the intrusion of bed mud overlying water, and its avoids overlying water and hole
The problems such as exchange of water.
To sum up, fast and effeciently separation and removal internal contamination are the technical bottlenecks of dystrophication remedying sludge.How
Main preservation medium and the release source for catching this endogenous pollution of substrate sludge object of pore water, in electric field migration and gravitational field migration
Under effect, pollutants in sediments is quickly subjected to migration in situ, collection, storage with pore water and concentrates discharge, is cut from source
Subtract sediment pollution total amount and release iron, shorten repairing efficiency, will be the new approaches for solving sediment pollution internal loading, there is pole
Big environment, economical, societal benefits and application prospect.
