Description
Technical field
The present invention relates to the desilting of the water bottom deposition such as natural water, municipal sewage system and refuse landfill
Field, more particularly to a kind of mud desilting bag and mud dredging method.
Background technology
Water is resource for the survival of mankind, and on the earth, 2/3rds area is awash.In these water resources
Among river only account for 0.006%, but the mankind but make use of the 54% of river waterr resources, it can be seen that the importance in river.It is existing
All contaminated in most of river of China, fast-developing economy but brings the destruction to environment, central to be provided with water
The pollution in source is particularly acute, and the particularly pollution of river waterr resources is even more and is particularly acute.Its river bed of the river that water body is contaminated
Contain substantial amounts of heavy metal substance among mud, these heavy metal substances can be released and enter into water under certain conditions
Among body, cause water quality to degenerate, become the source of water pollution.Substantial amounts of polluter can be deposited on water bottom mud
In layer, water quality is not only affected, and is highly detrimental to natural water self-cleaning, reduce its self-purification capacity, cause water quality to continue to bad
Direction develop, so natural water desilting is most immediately possible method for natural water water quality is improved, but the bottom of due to
The thickness of mud, the different dredgings still to mud of vertical distribution of pollutant concentration cause great difficulty, so that river
Road is administered difficult.The method for being usually used in natural water desilting at present has：Physical, chemical method.
Physical mainly includes Sediment Dredging and diversion erosion and deposition, and both approaches simply shift or dilute pollutant, can be right
Lower reaches are polluted, and are cured the symptoms, not the disease, can only be as the emergency measure for tackling sudden water pollution or as cities and towns river
The supplementary meanss of stream pollution control.
Chemical method mainly increases the settling property of non-dissolved contaminants in river by adding chemical agent, and by de-
Water mode, removes mud, but as natural water water capacity is big, this kind of method cost is very huge.And dehydration equipment long-time
Easily there is equipment fault in heavy-duty service, causes process cycle to increase.
Municipal systems mainly include urban wastewater treatment firm collecting-tank and other water treatment buildings, and townm refuse is filled out
Bury a collecting-tank.Contain a certain amount of insoluble pollutant in municipal wastewater and percolate, in usual technique, adopt grid
Pond removes this partial contamination thing, but disposal ability is affected by grid gap length, and the less pollutant of particle diameter can exist through grid
Collecting-tank gathers；There is certain hydraulic detention time additionally, due to water treatment building, especially refuse landfill collecting-tank
（The time of staying is typically more than 3 months）, prolonged to stop, microorganism amount reproduction in sewage, along with the new of microorganism
Old metabolism, generates substantial amounts of biological sludge, and this partial sludge short-term will not be impacted to processing structures, but long-play
The effective water capacity of collecting-tank can be caused to reduce, affect regulating reservoir Regulation capacity, meanwhile, contain a large amount of pollutant in the sludge for gathering
Matter, along with water inlet agitation, can cause influent load fluctuation change, affect wastewater treatment efficiency；In addition, with urban development,
The municipal sewage plant that most early stages build, is to meet due to explosive population growth, the requirement of displacement increase, need to carry out expansion and change
Build, need to clear up existing cell body during reconstruction, it is to be difficult to be collected at each mud for processing structures bottom in a large number
It is very reluctant.
Traditional method is typically adopted and takes out mud filter-pressing method, but operating cost is high；For refuse landfill collecting-tank, by
Long in landfill yard collecting-tank hydraulic detention time, cell body floor space is big, and bottom of pond is coated with the antiseepage film of cracky, takes out mud pressure
Filter technical difficulty is high, and equipment cost, total investment of engineering are huge.
The content of the invention
For the shortcoming and defect of traditional desilting technique, it is an object of the invention to develop a kind of low energy consumption, low input, clear
Become silted up reliable and stable desilting bag and the mud dredging method using the desilting bag.
To reach above-mentioned purpose, technical scheme proposed by the invention is：A kind of mud desilting bag, including bag, are located at
