Description
Technical field
The present invention relates to technical field of sludge treatment, in particular to the processing system of a kind of polluted bed mud desiccation and processing side
Method.
Background technique
With the propulsion of China's expanding economy and Development of China's Urbanization, industrial wastewater, the sanitary sewage of town street generation along the river
Deng being largely discharged into, river receives serious pollution, seriously destroys river ecosystem, influences resident living, and harmful to human is strong
Health.At present all there is different degrees of pollution in the river of China's most cities, especially in the relatively advanced city of industrial development
City, pollution are especially prominent.Pollutant into river is finally deposited in bed mud and is progressively enriched with, and is formed polluted bed mud, is
The crucial internal contamination of river and lake.Desilting and dredging is the major measure for administering river and lake endogenous pollution both at home and abroad at present, it is intended to be removed
Polluted bed mud in river, lake and reservoir water body reduces source pollutants content in river and lake body, promotes river and lake water quality, improves Ecology ring
Border.As riverbed sludge is desilted and dredged the development of engineering, a large amount of Dredged Sludge be manipulated so in order to it is urgently to be resolved again
One problem.
Since river and lake is by the pollution of littoral sanitary sewage, industrial wastewater etc., the accumulation of pollutants in waste water enters in bed mud, bottom
Mud complicated component, it is seriously polluted, it is black smelly obvious.It needs that bed mud is first passed through pipeline or groove tank car using traditional processing technique
It is transported to sludge handling stockyard and carries out post-processing, there are bed mud freight volumes greatly, apart from the problems such as remote, at high cost.In addition, aqueous
The bed mud that rate is high, intensity is low, grit content is high, by the technologies such as stockyard nature desiccation, manual intervention desiccation, bed mud drying time
Length, low efficiency form stench to breed bacterium；Common high pressure filters pressing mode carries out bottom-mud dewatering, and equipment loss is big, the service life
It is short, it easily blocks, treatment effect, which is difficult to reach moisture content, is down to 50%；And water pollutant content is high more than filters pressing, amount is big, processing difficulty
Greatly.In addition, a large amount of bed mud stockpiling occupies a large amount of land resource, environmental pollution is also easily caused.
Prior art processing bed mud haves the shortcomings that following: bed mud is passed through pipeline or slot by (1) conventional processing technique
Tank car is transported to sludge handling stockyard and carries out post-processing, and there are bed mud freight volumes greatly, apart from the problems such as remote, at high cost；(2) heap
The natural technologies such as desiccation or manual intervention desiccation in field, bed mud drying time length, low efficiency form stench to breed bacterium, occupy
Large amount of land resources；(3) common high pressure filters pressing mode carries out bottom-mud dewatering, and equipment loss is big, and the service life is short, easily blocks, processing
Effect, which is difficult to reach moisture content, is down to 50%.
Therefore, the quick minimizing in polluted bed mud original place and harmless treatment how to be realized, is avoided, reduce bed mud transport and it is remaining
Water process amount and processing difficulty extend service life of equipment, reduce sludge handling cost, reduce bed mud and store up land seizure, are
The training of channel administers significant problem to be solved at present.

Compression apparatus, sludge-tank, automatic medicine adding apparatus, bottom-mud dewatering device, residual water treatment device and dewatered sludge conveying device.
The sludge pipe of dredger is connect with the feed inlet of high frequency shale shaker 1, is acted on through high frequency shale shaker by the sand in bed mud
Processing is separated and transported outward to stone, rubbish, and will sieve lower moisture content by sludge pump is 99% (i.e. solid content 1%), partial size 60
The bed mud of~250 mesh is sent into Centrifugal concentrator 2.By flocculation solidified reagents chemicals dosing plant 31 plus flocculant and curing/stabilizing
Medicament carries out solidification and stabilization processing to pollutants such as heavy metals in bed mud, and accelerates bed mud concentration speed；It is tried by oxidation
Agent chemicals dosing plant 32 adds hydrogen peroxide, carries out Strong oxdiative processing to bacterium, virus and organic pollutant in bed mud, quick de-black is removed
It is smelly.The supernatant liquor of concentration is discharged directly into river, and lower sediment moisture percentage in sewage sludge is down to 94.8% (i.e. solid content
5.2%) it, is delivered in sludge-tank 4 and is kept in by sludge pump 103, meanwhile, the bed mud in sludge-tank 4 is delivered to by sludge pump 105
Further flocculation and immobilization processing in flocculation mixing channel 51, subsequently into dehydration and drying is carried out in folded spiral shell formula dewaterer 52, most
The mud cake obtained afterwards is discharged by Shaftless screw conveyor 7.Water is collected by collecting tank 53 more than the filters pressing that dehydration and drying generates, and is delivered to
It is handled in residual water treatment device 6, water outlet direct emission river up to standard.
The desiccation Dredged bed mud moisture content that the present embodiment obtains is 55~58%, without black smelly, up to " cities and towns are dirty after residual water treatment
Water treatment plant's pollutant emission standard " (GB 18918-2002) level-one A standard.
By above-mentioned implementation it is found that the present invention passes through bed mud concentration pretreatment, efficiently folded spiral shell machine dehydration and residual water treatment phase
In conjunction with, realize the integrated treatment of the quick desiccation in Dredged bed mud original place, the deodorization of bed mud de-black and residual water treatment, reach dredging bottom
Mud minimizing and innoxious purpose, are effectively reduced sludge handling cost, avoid secondary pollution, device conveniently moving, and engineering is fitted
It is strong with property.
Compared with prior art, polluted bed mud desiccation is carried out using the device of the invention, had the advantage that
1, concentration process, which adds flocculation agent, can accelerate the concentration speed of bed mud, improve bed mud concentrated effect；Pressure-filtering process
It adds flocculation agent and strengthens bed mud flocculating effect, solid content is up to 40%~50% after polluted bed mud drying and other treatment, bed mud volume
Reduce 40~50 times, reduce bed mud freight volume and transportation cost, reduces the soil that bed mud stockpiling occupies.
2, adding curing/stabilizing medicament can be by the heavy metal contaminants immobilization in bed mud；It is double with strong oxidizing property
Oxygen water by polluted bed mud it is black it is smelly effectively remove, realize the harmless treatment of polluted bed mud, and reduce residual water treatment difficulty and processing
Cost.
3, the continuous self-cleaning process of mobile realization that the folded spiral shell formula dewaterer used relies on fixed ring between the ring that moves about,
Avoid blockage problem and stop cleaning problem；Auger axis, fixed ring and the travelling ring of folded spiral shell formula dewaterer are using superhard
The preparation of matter wear resistant alloy material, is more suitable for the high riverbed sludge drying and other treatment of grit content, service life of equipment is long.
4, this polluted bed mud anhydration system uses modularization, the Automation Design, and each device composition of system is detachable, mountable
On environment protection dredging boat or dredging vehicle, equipment is connect with desilting and dredging, in engineering realize desilt and dredge-bed mud desiccation integral at
Reason, engineering adaptability are strong.
