Abstract
A river channel desilting method comprises the following steps of: sludge excavating, screening, conveying, centrifugal dewatering, sludge pumping, storing, transportation and drying incineration. Sludge of a river channel is treated after being dewatered by using a centrifugal machine set, and occupation to urban land and secondary pollution to an urban environment due to the sludge of the river channel are avoided. The total river channel desilting method is simple, is not high in input cost, is beneficial to being popularized in large and medium-sized cities, and is also beneficial to protecting the urban environment.
Description
Technical field
The invention belongs to Removal Technology field, river course, specifically is exactly a kind of method that adopts centrifugal chiller the river course to be carried out dredging operation.
Technical field
China is vast in territory, city river is numerous, each bar river course as the blood vessels in city all undertaking drink, the different function such as flood passage, water drainage, tourism, shipping, but because economic fast development, the not treated phenomenon that directly is discharged in the city river of various industrial refuses and household garbage occurs repeatedly, cause the city river alluvial, the lighter's polluted river, severe one can make the river course stop up, it is common to affect the navigation channel, therefore, keeps the cleaning of city river unimpeded, safety and sanitation just must in time regularly be carried out desilting to the river course.The method that at present general common channel cleanout is taked is: at first dredge with digging machine, then with ship mud is dug out, then mud is placed the cofferdam to carry out landfill through entrucking and carrying away behind the natural drying, the problem that the method for this channel cleanout exists is at first mud to be placed the cofferdam airing, needing requisition large tracts of land soil, secondly is to produce a large amount of backflow sewage, causes the secondary pollution river,, pollutant is evaporated in the air and can affects surrounding environment in the while mud airing process.Existing this channel cleanout mode is a kind of unlimited extensive style desilting mode.
Chinese patent CN1632244A discloses a kind of technique of channel cleanout, and this technique may further comprise the steps: (1) underwater desilting, excavation shipment; (2) water route transportation; (3) unload a ship, store; (4) clean ship returns and sails desilting site.This technique just simply transports riverway sludge, does not do any safeguard procedures and prevents secondary pollution to urban environment.
Summary of the invention
What all adopt for existing channel cleanout mode is open channel cleanout mode, the defective that causes secondary environmental pollution, the invention provides a kind of method that adopts centrifugal chiller the river course to be carried out dredging operation, adopt the centrifugal chiller dewatering process, avoided riverway sludge to urban land take and to the secondary pollution of urban environment.
Technical scheme
In order to realize above-mentioned technical purpose, the present invention designs a kind of method of channel cleanout, it is characterized in that, it comprises following step:
(I) mud excavates, and soon the dual-purpose mud wheeled digging machine in water route is opened and resided in the river course that needs cleaning, excavates the mud in the riverbed by grabbing bucket;
(II) sub-sieve, conveying, being about to grab bucket is excavated among the step I mud pours in the sub-sieve conveyer in the cargo ship, the sub-sieve conveyer carries out preliminary sub-sieve to the mud in the riverbed, solid particle is separated with mud sewage, mud sewage enters the boat-carrying mixing pit and mixes, and solid particle transports out of the river course;
(III) centrifugal dehydration is sent the mud sewage that mixes through the boat-carrying mixing pit in the Step II into the horizontal screw centrifuge group and is carried out the separating and dehydrating disposal;
(IV) sludge pumping, the mud that is about to dispose through dehydration among the Step II I is delivered to storage device with sludge delivery pump;
(V) store, storage device is deposited the mud that obtains among the step IV temporarily;
(VI) transportation is transported to anhydration and incineration equipment with the mud that is stored in storage device;
(VII) anhydration and incineration passes through the equipment dried burning of anhydration and incineration with transporting the mud that comes among the step VI.
Further, water passes into and carries out mud concentration of wastewater allotment in the pond in the boat-carrying mixing pit in the clear liquid conduct that the sludge dewatering disposal obtains among the Step II I.
Beneficial effect
The mode of processing again after the present invention utilizes centrifugal chiller that riverway sludge is dewatered; avoided riverway sludge to urban land take and to the secondary pollution of urban environment; the method of whole channel cleanout is fairly simple; input cost is not high yet; be beneficial in big and medium-sized cities and promote, be conducive to urban environment protection.
Description of drawings
Accompanying drawing 1 is process chart of the present invention.
Accompanying drawing 2 is flow sheets of the present invention.
The specific embodiment
Below in conjunction with drawings and Examples, the present invention will be further described.
Shown in attached Fig. 1 and 2, a kind of method of channel cleanout, it comprises following step:
First step mud excavates, and soon the dual-purpose mud wheeled digging machine in water route is opened and resided in the river course that needs cleaning, excavates the mud in the riverbed by grabbing bucket.
Second step sub-sieve, conveying, being about to grab bucket is excavated among the step I mud pours in the sub-sieve conveyer in the cargo ship, the sub-sieve conveyer carries out preliminary sub-sieve to the mud in the riverbed, solid particle is separated with mud sewage, mud sewage enters the boat-carrying mixing pit and mixes, and solid particle transports out of the river course.
The 3rd step centrifugal dehydration is sent the mud sewage that mixes through the boat-carrying mixing pit in the Step II into the horizontal screw centrifuge group and is carried out the separating and dehydrating disposal, and water passes into and carries out mud concentration of wastewater allotment in the pond in the boat-carrying mixing pit in the clear liquid that the obtains conduct.
The 4th step sludge pumping, the mud that is about to dispose through dehydration among the Step II I is delivered to storage device with sludge delivery pump.
The 5th step stored, and storage device is deposited the mud that obtains among the step IV temporarily.
The transportation of the 6th step is transported to anhydration and incineration equipment with the mud that is stored in storage device.
The 7th step anhydration and incineration passes through the equipment dried burning of anhydration and incineration with transporting the mud that comes among the step VI.
The process of this method is: at first the dual-purpose mud wheeled digging machine in water route is opened and is resided in the mud that excavates in the river course that needs cleaning in the riverbed, directly it is rendered to the sub-sieve conveyer, the sub-sieve conveyer boom is located on the cargo ship, sub-sieve conveyer crawler belt is lattice-shaped, call in after the sewage sludge seepage in the mixing pit of cargo ship, mix by agitator in the pond, after being formulated into adaptation horizontal screw centrifuge group concentration for the treatment of, by the cutting machine in the centrifugal chiller, the acting in conjunction of delivery pump, the mud sewage transport is entered horizontal screw centrifuge carry out mud-water separation, clear liquid part after the separation can be used as middle water and passes into and carry out in the pond allotment of mud concentration of wastewater in the mixing pit, all the other directly enter the river course, and mud out (solid content can reach 45%) is by the conveyer of horizontal screw centrifuge group, be transported to sludge delivery pump, by sludge delivery pump mud is squeezed into storage device again, rely on car and boat with the mud shipped off-site, then process by anhydration and incineration equipment.
The mode of processing again after the present invention utilizes centrifugal chiller that riverway sludge is dewatered; avoided riverway sludge to urban land take and to the secondary pollution of urban environment; the method of whole channel cleanout is fairly simple; input cost is not high yet; be beneficial in big and medium-sized cities and promote, be conducive to urban environment protection.
