Description
Technical field
The present invention relates to a kind of mud renovation techniques, especially a kind of to contain heavy metal and the biggish riverway sludge of silt content
Renovation technique.
Background technique
With the quickening of Development of China's Urbanization, more and more populations pour in city, and city complete sets of basic equipment renewal of facility expands
Volume flow rate degree does not catch up with the speed of expansion of population size and the rate of expansion in city, and the excessive contaminants that people's life production generates are given
Urban environment brings immense pressure.The untreated sanitary sewage in part and industrial wastewater, the next pollution of area source with precipitation
Object enters river, serious to increase water pollution load, the self-purification capacity beyond river.Meanwhile river's blue lines are occupied in urban construction,
Natural tracer changes its course, and hydraulics are poor, and the human factors such as natural ecological slope protection artificial aging destroy river natural ecology
Environment greatly reduces the environmental carrying capacity in river, causes urban river water quality worsening.Black and odorous water has become China at present
One of common problem in Urban Water Environment.
Common process for treating sludge is minimizing both at home and abroad at present.Dredged bed mud minimizing is exactly to pass through engineering measure,
Composition harmless in bed mud is separated；Or by dewatering means, water in bed mud is separated, bed mud quantity is reduced,
Different by decrement mode, Dredged bed mud decrement can be divided into sub-sieve decrement and dehydration decrement two major classes.From bed mud granularmetric analysis,
Containing the ingredients such as dust, gravel, powder and clay in Dredged bed mud, if by dust, gravel and part powder in bed mud the bottom of from
It is separated in mud, this part Sediment Composition moisture content is down to 30% hereinafter, being not necessarily to dehydration；This constituent part does not adsorb weight
Metal component, the content of organic matter is low, is not necessarily to curing process, is directly used in building sand, can greatly reduce so solid in bed mud
This constituent part is separated the part decrement that Dredged bed mud can be realized by body object ingredient.Remaining dredged mud part powder
With clay component, containing pollutants such as certain organic matter, heavy metals, moisture content may be up to 90% or more, and natural landfill is difficult to take off
How water arranges reasonable process flow, so that mud comes out from channel cleanout, until processing is completed, on the basis of dehydration, more
Good heavy metal by mud and some harmful elements separate or solidification, realizes bed mud minimizing and harmless treatment, always
It is a problem.
Summary of the invention
To solve the above problems existing in the prior art, the present invention, which provides, a kind of contains heavy metal and the biggish river of silt content
Road mud renovation technique guarantees that mud is handled completely by mud-water separation path, and pollutant is all removed.
To achieve the above object, the technical solution of the application are as follows: one kind is containing heavy metal and the biggish river of silt content becomes silted up
Mud renovation technique, the specific steps are as follows:
A, mud transports
The slush pump that ship is inhaled by the strand in river will become silted up by the sludge pumping in river into mud screening transfer car(buggy)
Mud is transported to washing at husky recycling；
B, husky recycling is washed
Mud is pumped to from transfer car(buggy) by slush pump and washes husky recycling all-in-one machine, by washing husky processing, by mud with
Sandstone separation, sandstone is by Belt Conveying to sandstone stockyard, and mud is pumped to settling tank by slush pump；
C, it settles
Mud carries out natural subsidence, mud-water separation in settling tank；
D1, sewage treatment
The sewage isolated is extracted out by water pump, is pumped to vehicle-mounted soil diafiltration desorption system, the water quality monitoring after desorption
It is discharged after reaching qualification；
D2, Treatment of Sludge
Sludge after precipitating is pumped in static mixer by slush pump, meanwhile, by pump flocculant is delivered to it is quiet
In state mixer, mud and flocculant are sufficiently mixed, enter horizontal spiral centrifuge by mixed mud, by from
Heart effect, so that mud carries out mud-water separation again, the sewage separated enters vehicle-mounted soil diafiltration desorption system, point
Separating out the mud come becomes solid-state mud；
E, mud reparation
Solid-state mud is delivered to elution circuit by belt transmission, by the way that curing agent is added in elution circuit, to solid-state
Heavy metal contained in mud carries out curing process, the repair of mud is realized with this, the mud for repairing completion passes through belt
Transmission, is delivered to quick stockyard, so completes the reparation of mud.
Further, mud screening transfer car(buggy) is a kind of vehicle-mounted mud collection stocking system.
Further, the elution circuit is vehicle-mounted integrated form Soil leaching prosthetic device.
Further, the settling tank can excavate according to the actual situation in disposal field.
The present invention due to using the technology described above, can obtain following technical effect:
1, the present invention is vehicle-mounted integrated form device for institute's corollary equipment, mobile fast, and it is small to repair occupied area.
2, all devices are that mud is dedicated, can modularization assembling, integrate convenient and efficient.
3, the present invention guarantees that mud is handled completely by mud-water separation path, and pollutant is all removed.
