Description
Technical field
The invention belongs to surface water body bed muds to administer field, in particular to a kind of surface water body bed mud treatment in situ system.
Background technique
Surface water body bed mud Treatment process can be divided into three categories, i.e. peripheral doses, chemical remediation and biological prosthetic.
Peripheral doses technology includes sediment digging, bed mud covering and sediment aeration.Sediment digging is by excavating surface layer
Polluted bed mud containing high concentration N phosphorus recycling, heavy metal and hardly degraded organic substance, to remove the reparation hand of sediment pollution
Section.Being considered it when the concentration of pollutant in bed mud is higher by 3~5 times of background values, there are potential to the mankind and aquatic ecosystem
Harm, it is contemplated that dredged.Sediment digging is most common surface water body bed mud Treatment process.Sediment digging has as follows
Feature: (1) retaining original ecological characteristic as far as possible, creates conditions to dredge the ecological reconstruction in area, adequately protect bio-diversity；
(2) pollutant contained in bottom mud in lake is removed, release of the bed mud middle and high concentration pollutant to water body is reduced；(3) mud layer is dredged
Thickness is generally less than 1m, by the growth for removing contaminating endogenous, control aquatic macrophyte and is conducive to wanting for ecological recovery
It asks determination to dredge depth, and precision controlling will be dredged in 5~10cm；(4) it dredges equipment using professional environmental protection to construct, strictly
Construction progress is monitored, avoids polluting object diffusion and particulate matter settling flux because of dredging disturbance, prevents secondary pollution from occurring；(5)
Specially treated is carried out to bed mud according to bed mud and water pollution property and degree difference, avoids dredging pollutant and other environment is caused
Pollution.Bed mud covering realizes water body and polluted bed mud mainly by constructing one or more layers covering on polluted bed mud
Physical isolation, and using the effects of absorption and degradation between covering material and pollutant to reduce the nitrogen and phosphorus in bed mud
The pollutants such as salt, heavy metal and hardly degraded organic substance are migrated to water body.Common covering material includes that natural material is (such as clean
Deposit, soil, sand, gravel), modified clay (such as organic modified bentonite, organic modified zeolite, organically-modified kaolin)
With active covering material (such as Zero-valent Iron, apatite, calcite).Toppled in common engineering by mechanical equipment surface layer, moved
Covering is placed on bed mud by the modes such as barge surface layer dispenses, water-jet Surface mulch and barge pipeline cover under water to be formed
Coating.In recent years, aeration aerating technology also starts to be used in bed mud improvement.Some researches show that aeration aeratings obviously to control
The release of Nitrogen In Sediment phosphorus processed.In addition, oxygen can improve the anaerobic environment of bed mud, aerobic microbiological quantity and activity are improved,
Accelerate the removal of nitrogen phosphorus and organic matter.
The principle of chemical remediation is that chemical reagent occurs to aoxidize, restore, precipitate, hydrolyze, be complexed, polymerize etc. instead with pollutant
It answers, separates pollutant from bed mud, is converted to low toxicity or nontoxic form.Currently used chemical agent has aluminium salt, molysite, life
Lime, Ca (NO3) 2, CaO2, H2O2 and KMnO4 etc..Although chemical remediation energy consumption is lower, investment is less, there are also problems.
Firstly, there is the possibility for increasing water body toxicity in chemical agent；Secondly, chemical agent may cause pollutant abnormal release and
Stable state changes.In general, chemical remediation may be more suitable for emergency processing.Endogenous pollution is carried out in optional other technologies
When control, chemical remediation is not used as far as possible, in order to avoid causing secondary pollution to water body, increases water body treating cost.
Bioremediation technology may be summarized to be using a kind of or a few class in plant, animal and microorganism to the dirt in water body
Dye object is adsorbed, is degraded, is converted, to realize the technology of water environment purification and restoration of the ecosystem purpose.Bioremediation technology is main
Including phytoremediation, microorganism remediation and animal reparation.Phytoremediation is the one or moreization for being resistant to and being accumulated with plant
Premised on learning element, using plant absorption, degradation, it is fixed the effects of, effectively remove organic in water and inorganic pollution, reach net
Change the recovery technique of bed mud purpose.Microorganism remediation i.e. utilize microbial metabolism, absorption the effects of by the pollutant in bed mud into
Row is cut down or the recovery technique of attenuation.Animal reparation is to go to denitrogenate phosphorus, heavy metal by the feeding behaviour or accumulation ability of animal
And organic pollutant, means are repaired to reach a kind of biology of bed mud purification purpose.Compared with Traditional materialized technology, biology
Recovery technique is built and operating cost is relatively low, and operation and maintenance technology is also relatively easy.But bioremediation technology there is also
Some problems: (1) the biological growth period is longer, and general responding time is longer；(2) system of the biological activity vulnerable to environmental condition
About (such as temperature), repairing effect are likely to occur fluctuation with the variation of environment；(3) biology is limited to pollutant tolerance, is going out
When existing high concentration burst Pollution situation, biology may be dead and lose repair ability, and if dead death fail it is clear in time
Except may cause secondary pollution of water.
In surface water body sludge handling, in earth's surface after needing to dig out bed mud existing physics and chemical treatment method more
Land is handled, and can be occupied large area soil and be may cause secondary pollution！Meanwhile some physics in situ, chemical treatment skill
Also it is slow or easy to surface water body generation secondary pollution problems to there is treatment effeciency more in art and biologic treating technique, and is limited
System！
