Description
Technical field
The invention belongs to architectural engineering, municipal works and field of environment engineering technology, are related to a kind of mud continuous with mud
Dehydrating and curing integral process.
Background technology
Especially the southeastern coastal areas are due to level of ground water height for the Changjiang river areas to the south of China, and geologic structure is complicated, public,
Industry, civil buildings, as building foundation, during pile foundation construction, have a large amount of construction slurries to produce typically all using pile foundation
(per cubic natural, soil, can produce 4～5 cubes of mud, and each foundation engineering generally produces thousand of or even tens side's mud),
With building for all kinds of engineerings such as the continuous quickening of urbanization process, high level, high-rise building, subway, super expressway, large bridge
If more and more, the yield of mud is also increasing.Such as deal with improperly and will cause environmental pollution and the wasting of resources.
The overwhelming majority for accounting for current mud capacity is directly discharged in the outward transport of mud, and this extensive processing mode is easily made
Into serious environmental pollution and wasting of resources phenomenon：1) environment is polluted, the random exhaust emission water source of construction slurry, destruction nature is planted
Quilt, hardened soil affects environmental beauty；2) water quality is destroyed, the mud of rivers is entered steathily not only makes rivers muddy, the life of destruction river course
State safety, jeopardizes city domestic water safety, and makes channel filling, affects ship's navigation；3) urban operating mechanism is destroyed, is entered steathily
The mud of the facilities such as sewer easily causes the destruction of city planting ductwork, blocks pipeline.It is increasingly strict with Environmental Protection in China policy
And land resource growing tension, construction slurry effective process is increasingly urgent.
In order to improve the water quality in river lake, it is ensured that river course is unimpeded, need to carry out dredging and desilting engineering.According to statistics, only China
The dredging silt amount that produces every year of Delta of the Pearl River area just reach 80,000,000 m3Left and right, riverway sludge water environment has following existing
Shape feature：River course river networks structure interweaves in length and breadth, and alluvial is serious, and sludge pollution is serious, and drift wide material sources, composition are multiple
It is miscellaneous；Water quality severe contamination, factor are numerous and jumbled.Therefore, in China, effective disposal of dredging silt and recycling problem are equally urgently
It is to be solved.
Construction slurry and the important step that riverway sludge dehydration is that it is processed.Currently, China's sludge dewatering mode with
Based on mechanical dehydration, including pressure extrusion dehydration and centrifugal dewatering etc..Conventional dewatering machine includes belt filter press, sheet frame
Pressure filter, vacuum filter and spiral pressing dehydrator etc..
Chinese patent CN204727749U discloses a kind of construction slurry datatron.Sludge is by mud inlet into vacuum point
From case, high speed gravity electric rotating machine is rotated bar and rotates by bearing, the rotating vane agitation mud on swingle, while instead
Drive to motor and reversely rotate bar rotation, reversely rotate blade and stir mud from vertical angles, so as to depth destroys slurry liquid
Associativity, the stability of the adhesiveness, granular soil and water of the composite colloid in accelerated decomposition slurry fluid subsequently passes through plasma discharge pressure
Mud is entered natural sedimentation case, two casees operated in turn, one case natural sedimentation, another case pump drainage design requirement certified concentration by power pump
Serosity, mud pumps pump and extracts out in the sludge after precipitation, and water guide net leaches moisture in mud, and Vacuum suction pump extracts out moisture
Water softener is delivered to, high pressure rushes net rifle and water guide net is rinsed when water guide net is blocked, and the clear water after process is softened and passes through by water softener
Water pipe is derived.The invention overcomes the problem that polluted source recirculation is unable to reasonable employment, it is to avoid using chemistry such as flocculant
Product, makes prior art more perfect with equipment.The conditioned rear dewatered sludge moisture content of the invention is higher, sludge reduction effect
It is unobvious.
Chinese patent CN201410413690 discloses a kind of portable river lake and desilts and dredges method for sludge treatment and device.
The method includes:Step a：Sludge is stored in the Temporary Cofferdam storage basin that river loke shore side is built；Step b：By integrated loading
The container crane for having sludge dewatering system is transported to by storage basin；Step c：Sludge is extracted from storage basin and sends into sludge dewatering system
In Chamber Type Diaphragm Filter Press carry out filter-press dehydration；Step d：Squeezed using press pump；Step e：By moisture content significantly
The sludge transhipment of reduction carries out following resource disposal.The device includes building in river loke shore side for storing dirt of desilting and dredging
The container of the cofferdam storage basin, sludge dewatering system and loading sludge dewatering system of mud.The invention can drop to a certain extent
Low-water-content, reduces the pollution in transport process.But there is equipment can not continuously work, enter mud, filter pressing link and separate, mud takes off
The water cycle is long, and disposal ability is limited, and equipment volume is huge, the defect such as installed power is high.
Chinese patent CN201210582961.9 discloses a kind of river course, the Deep dehydration treatment method of interior lake silt, institute
The deep dehydration method stated loads TiO first to add in mud2Photoelectric, under the action of uv light, imports air
Source current-carrying high energy electron, makes the constitution water of organic matter and mushroom in mud, suction Bao Shui, water of crystallization become flowable Interstitial Water,
Then adding compound coagulation agent carries out flocculation reaction, and dehydration is obtained final product, and it is excellent that the invention has that the response time is short, dehydrating effect is good
Point, but the dewatering is higher to equipment requirements, it is cumbersome, it is unfavorable for large-scale popularization and utilization.
The content of the invention
The shortcoming of prior art in view of the above, it is an object of the invention to provide a kind of mud and mud continuous dehydration
Curing integrated technique, for solving prior art in lack for granule is tiny, difficult-to-condense sedimentation construction slurry and river course silt
