In the invention, the integral design of sediment dewatering processing device for urban landscape water pollution is realized; the sludge is immediately dried and dewatered while dredging; and the processed sludge can be directly used in the agricultural field, therefore, the pollution on the environment is avoided.
Description
Technical field
The invention belongs to dredger, particularly a kind of strand is inhaled formula sludge dewatering dredger.
Background technology
Along with The development in society and economy, it is more and more serious that the water quality of landscape water in China city and the suburbs worsens phenomenon.In order to improve the water pollution situation, control landscape water body endogenous pollution, bed mud are dredged as a kind of thorough governing measure in polluting treating landscape water body and recovering, and are selected for use by the treating landscape water body engineering just more and more.According to incompletely statistics, only the lake of 1998～2005 years environmental dredgings just reaches 40, relates to more than 20 in city, dredges out about 3758.3 ten thousand m of bed mud of lake body
3Bed mud is a main body with the organic matter, contains a large amount of hazardous substancess such as pathogen, virus, parasitic ovum, if can not effectively be disposed, causes secondary pollution unavoidably, and this makes bed mud dispose and resource becomes inevitable; Simultaneously, be rich in organic elements such as nitrogen, phosphorus in such bed mud, also have the metallic element of certain content, this has created objective condition for the resource of bed mud.As one of core content of environmental dredging, innoxious, the resource of pollution by dredging bed mud has become new difficult point, new challenge in the comprehensive environmental improvement work.
City appearance water body dredging bed mud water content is up to more than 95%; Adopt the mud after mechanical fast dewatering is handled significantly to subtract appearance; It is original 1/4～1/5 that volume can be compressed to, and stable performance, odorless, no causal organism, alleviated second environmental pollution greatly.Compare with cities such as sewage sludge, industrial residue are useless admittedly; The pollutant component of landscape water body dredging bed mud is simple; Content is low; Physicochemical property and soil are approaching, and wherein nutriments such as organic matter, nitrogen, phosphorus are abundant, can increase land fertility, the farming performance of improving the soil, practice thrift a large amount of disposal costs.Therefore the farmland input is a kind of resource recycling approach that meets continuable development principle.
Aspect sludge dewatering, Japan develops portable continuous dehydration ship, and mud dehydration plant is laid aboard ship; Make equipment have mobility; Can add harmless agglutinant with concentrating the mud that is poured in the water to collect the coagulation sedimentation groove continuously, reach requirement through vacuum dehydration.Aspect the heavy metal removal; Worked out both at home and abroad a series ofly be easy to grasp, chemical method simple to operate; Promptly throw in chemical agent heavy metal in the mud is transformed to soluble ionic state or complex ion attitude by the compound of soluble attitude, reach the purpose that reduces content of beary metal.But current advanced both at home and abroad dredger is just collected mud and transportation, can not it in time be handled to reach dehydration indexes, can not realize content of beary metal is controlled at below the agricultural standards.
Summary of the invention

2. strand according to the invention is inhaled formula sludge dewatering dredger, and mud water content and content of beary metal after the processing all satisfy the mud agricultural standards, and the dried mud water content after can detecting displacement and handling, and can directly transport to be used for the farmland input.
3. the present invention has realized the integration design of city appearance water body polluted bed mud dehydration treatment equipment, in dredging silt, dehydrates immediately, and the mud after the processing can directly be transported to agricultural input, has avoided pollution on the environment.
Description of drawings
Fig. 1 is an external structure sketch map of the present invention;
Fig. 2 is the structural representation of sludge treatment device of the present invention.
The specific embodiment
Be described in detail embodiments of the invention below in conjunction with accompanying drawing; Need to prove that present embodiment is narrative, is not determinate, can not limit protection scope of the present invention with this.
A kind of strand is inhaled formula sludge dewatering dredger, comprises that hull 3 reaches the hydraulic control device 2 of the control hull location of on hull, installing, the control room 4 of installation electrical control system.
Innovative point of the present invention is:
Sludge treatment device 5 is installed on hull, and this sludge treatment device comprises extracting unit, sieve unit, heavy metal processing unit, dosing unit, dewatering unit, deodorizing unit, dewatered sludge collector unit, wastewater treatment exhaust unit.The self-priming sludge pump 6 of extracting unit is communicated with the twisting sucker head 1 of the sludge treatment device of installing alow, and this twisting sucker head stretches out hull bottom and is communicated with landscape water body, extracts the higher muddy water of mud content; The muddy water that is drawn into gets into the vibrosieve 7 of sieve unit through the self-priming sludge pump, and through this bolting, sand is tackled and toppled in the sand storage tank 9; On the vibrosieve of sieve unit and the pipeline between the dewatering unit heavy metal processing unit is housed, this heavy metal processing unit reduces the content of beary metal of muddy water in the pipeline by heavy metal treating apparatus 8 and pipeline connection; The dosing unit is housed on the pipeline between heavy metal processing unit and the dewatering unit, and this dosing unit adds pipeline by Scatula 10 and pipeline connection through the dosing in the valve control Scatula; Vibrosieve connects the belt filter press 11 of dewatering unit through pipeline; Belt filter press is communicated with Vibratingfluidbeddrier 15; Belt filter press is communicated with the wastewater treatment exhaust unit; The wastewater treatment exhaust unit is made up of the clarifier 13 and the wastewater discharge pipe of being installed 14 pipelines such as grade of Vibratingfluidbeddrier, and this wastewater discharge pipe links to each other with the discharge pipe line of the other end of belt filter press; On the pipeline that is communicated with clarifier, flow meter 12 is installed, the wastewater discharge pipe of this clarifier is communicated with landscape water body; The mud outlet of this Vibratingfluidbeddrier connects the storage mud jar 17 of dewatered sludge collector unit, on the pipeline between this Vibratingfluidbeddrier and the storage mud jar moisture content detector 16 is installed; Be connected with an active carbon deodoriser 18 on the air outlet slit of Vibratingfluidbeddrier.
Dredging method of the present invention is:
During dredged channel mud, with the hull location, the dredging tube that will have twisting sucker head is put in the landscape water body bed mud earlier; Open the self-priming sludge pump, the mud that suction comes up sieves processing through vibrosieve, and will intercept the sand removal in sand storage tank; Sand storage tank is equipped with the automatic sensing device; In the time will being full of, timely cleaning is convenient in the prompting that gives the alarm.The mud that screens gets into the heavy metal treating apparatus to reduce content of beary metal; Mix in pipeline with an amount of flocculant that Scatula is thrown in again; Get into belt filter press subsequently and carry out press filtration; The waste water that leaches discharges back landscape water body after reaching the view water quality standard by the processing of the clarifier on the wastewater discharge pipe, and by displacement under the cmf record.Slice gets into Vibratingfluidbeddrier and further dewaters after the press filtration, under the vibration force effect, and slice along continuous straight runs throwing continuous motion forward, hot blast is upward through fluid bed and slice heat exchange, and the air active carbon deodoriser of flowing through is discharged into outdoor.Pour storage mud jar sealed storage after dried mud detects through moisture content detector into, can directly be transported to agricultural input.
The parts that present embodiment is not described in detail are prior art.
