Description
Technical field
The utility model relates to enhancement of environment technical fields more particularly to a kind of sediment in-situ to solidify prosthetic device.
Background technique
There is black-odor riverway phenomenon in China major part city network of waterways, tracing it to its cause is that long-term pollution input and deposition are led
Cause oxygen balance system in river unbalance.Wherein there is quite a few pollutant final by approach such as absorption, complexing, flocculation, sedimentations
It is deposited in river bottom mud and gradually accumulates.Due to long-term continuous enrichment accumulation, pollutant concentration is usually water body in bed mud
The order of magnitude multiple of middle pollution concentration.When environmental conditions change, the pollutant in bed mud can return to water phase, generate " secondary dirt
Dye " aggravates water pollution.
Currently, mainly having peripheral doses, chemical remediation and biological prosthetic to the processing of mercury both at home and abroad.Physics
Repairing is mainly Sediment Dredging, be transferred to behind land be dehydrated, returning to the field, landfill etc., the technology repair it is quick, but invest at
This height, usual project amount is big, and the settling flux effect in Dredging Process may adversely affect water body environment, or even can
The stabilization of water ecosystem can be influenced.The transfer of Dredged Sludge pollutant and post-processing will bring huge engineering to consume, and
There may be secondary pollutions.Therefore, based technique for in-situ remediation just seems particularly significant.Chemical remediation is added to polluted bed mud surface
For chemical agent with fixed-contamination object, the technological investment is few, quick, but chemical remediation is typically only capable to for specific pollution in bed mud
The release of object, and the technology is usually used in the landscape water bodies such as Urban Parks lake, it is higher using then risk in water source type water body.It is raw
Object recovery technique is with ecological and by favor, the biological prosthetic degradation for depending on plant and microorganism.It is aquatic
The growth of plant is related with season, and the uncertainty of pollutant causes the selection of plant difficult.The growth activity of microorganism
It is influenced by factors such as temperature, PH, dissolved oxygens, repair process is relatively slow, the period is partially long, is not yet received in river reparation and pushes away extensively
Extensively.
Compared to other technologies, bed mud soverlay technique, which refers to, adds covering on bed mud surface, can effectively avoid to water
The interference of body and bed mud environment, and covering generallys use natural minerals cheap and easy to get or using plant as the environmentally friendly of raw material
Material is far below chemical agent to environmental hazard.At present sand and gravel etc. be study more covering material at present, but these
Inert material is poor to the solidification of the pollutant of sediment release, therefore, the bed mud control using active covering material occurs
Technology processed, but disturbance of the existing active coating vulnerable to current scour and air quantity etc..As patent " it is quickly former to launch modified zeolite
The method that the waters river Deng Heichou is administered in position " (201710436154.9), it " covers monolayer-modified biofilm zeolite in-situ persistently to repair
The method of serious pollution bed mud " (201410312760.6), etc. with the form building covering system of single layer covering, implementation process
In inevitably there is the loss of covering material.In addition, as patent " covering material of Nitrogen In Sediment immobilization in-situ immobilization a kind of and
Preparation method " (201210206786.3), " a kind of the bed mud active barrier system and method for the release of control sedimentary phosphate "
It (201210246668.5), is not carried out and is repaired to synchronizing for multiple pollutant for single nitrogen or phosphorus pollution amelioration
It is multiple.
Recovery technique is covered in situ therefore, it is necessary to a kind of efficient stable to solve the above problems.
