Description
Technical field
The invention belongs to riverway sludge Treatment process fields more particularly to a kind of riverway sludge ecology to recycle improvement side
Method.
Background technique
By after a certain period of time, bottom of river channel can accumulate a large amount of mud, the presence of mud will lead to river water quality be deteriorated,
Water level rises, and influences the shipping ability and flood control-discharge dyke effect in river, it is therefore desirable to clear up the mud in river.Tradition
Sludge dewatering technique mainly have: natural-dehydration seasoning, vacuum method and geotextile tube bag method.Natural-dehydration seasoning is benefit
Natural-dehydration, drying are carried out to mud with solar energy, cross-ventilation；Vacuum method is to carry out overlay film to mud, vacuumize
Processing；Geotextile tube bag method is that high-moisture percentage mud or mud are squeezed into geotextile tube bag, using geotextile tube bag water penetration, to mud
It carries out densification and shelves promotion dehydration.But to there is construction period longer for above-mentioned dewatering, needs to occupy for a long time a large amount of
Place, and sealing and harmless treatment are not carried out to the harmful substance of mud, there are the potential risks of pollution transportation.
Summary of the invention
The object of the present invention is to provide a kind of riverway sludge ecologies to recycle administering method, and it is heavy that mud in river is collected
It forms sediment and improves, through dehydration equipment deep dehydration, mud cake is pressed into revetment brick and mats formation in river levee slope surface after dehydration, and surface revetment brick covers
Plantation greening turf or short bushes in blinding, reduce the destruction of water flow and other adverse circumstances to river levee, prevent water and soil stream
It loses.
In order to achieve the above objectives, the technical solution adopted by the present invention is that:
A kind of riverway sludge ecology recycling administering method, comprising the following steps:
(1) mud recycles: it the mud in river is collected and is transported to carries out staticly settling 0.5-3h in concentration basin, it then will be upper
Layer clear liquid is back in river；
(2) mud is quenched: the mud that step (1) is collected into being conveyed into conditioning tank by slush pump, then adds sludge tune
Agent is managed, conditioner is at least one of polyacrylamide, aluminum sulfate, aluminium chloride, ferric sulfate, iron chloride, and conditioner additive amount is
2 ~ 10min is stirred in the 0.3 ~ 1% of mud weight；
(3) deep dehydration: being carried out dehydrating dehydration equipment is entered by quenched sludge in step (2), and dewatering time 5 ~
15min makes dewatered moisture percentage in sewage sludge 40 ~ 65%；
(4) make revetment brick: the sludge that deep dehydration is crossed is added in prefabricated frame, is pressed into shield by plate hydraulic device
Slope brick, revetment brick is paved on river levee, in revetment brick surface overlying soil；
(5) planting plants: in overlying soil surface planting plants.
Further, the step (2) needs to filter out the solid refuse in mud through multistage grid before mud is quenched.
Further, the step (3) needs for supernatant to be back in river by water pump before deep dehydration.
Further, the device for dehydrating sladge waste is integrated device for dehydrating sladge waste, ordinary belt device for dehydrating sladge waste, plate
One of frame filter press, folded spiral shell machine, centrifuge or at least two combination.
Further, pressure is 5 ~ 20MPa when production revetment brick in the step (4).
Present invention has the advantage that riverway sludge recovery method provided by the invention is easy to operate, dehydrating effect
Good, mud recycles, ecological, environmental protective, and treatment cost is low.

Specific embodiment
As shown, a kind of riverway sludge ecology recycles administering method, comprising the following steps: mud recycling: by river
Mud in road is collected and is transported to and carries out staticly settling 0.5-3h in concentration basin, and then supernatant liquor is back in river,
Then the solid refuse in mud is filtered out through multistage grid；Mud is quenched: the mud that step (1) is collected into is defeated by slush pump
It is sent into conditioning tank, then adds sludge conditioner, conditioner is polyacrylamide, aluminum sulfate, aluminium chloride, ferric sulfate, chlorination
At least one of iron, conditioner additive amount are the 0.3 ~ 1% of mud weight, stir 2 ~ 10min；Deep dehydration: will be by quenched
Mud supernatant is back in river by water pump, and lower layer's mud is conveyed into the conditioning tank of device for dehydrating sladge waste by slush pump
It is carried out dehydrating, 5 ~ 15min of dewatering time, makes dewatered moisture percentage in sewage sludge 40 ~ 65%, the device for dehydrating sladge waste is
One of Integral sludge dehydration equipment, ordinary belt device for dehydrating sladge waste, plate and frame type filter-press, folded spiral shell machine, centrifuge or
At least two combination；Make revetment brick: the sludge that deep dehydration is crossed is added in prefabricated frame, passes through plate hydraulic device
It is pressed into revetment brick, revetment brick specifically produces are as follows: revetment brick production site has the revetment brick of flat plate hydraulic machine and certain shapes pre-
Frame processed, frame inside dimension are 40*40*5cm, prefabricated revetment brick frame are placed on flat plate hydraulic machine work top, side
Sludge or overburden soil after suitable deep dehydration is added in frame inside, applies the pressure of 12MPa, sludge pressure to sludge by hydraulic press
Real and frame connecting shaping, obtains revetment brick, and there are two types of the revetment bricks of compression moulding, after by concrete outline border and dehydration
Mud cake compression moulding, mud cake is added in concrete outline border after 30 ~ 45kg deep dehydration, is compacted, is obtained by flat plate hydraulic machine
Integrally formed revetment brick.Another be outside concrete frame bottom be added half height dehydration after mud cake, i.e., 15 ~
Mud cake after the deep dehydration of 22.5kg, by flat plate hydraulic machine compression moulding, top remaining space fills 10 ~ 15kg overburden soil,
It is compacted by flat plate hydraulic machine, obtains second of revetment brick and revetment brick is paved on river levee, in revetment brick surface overlying soil,
Pressure is 5 ~ 20MPa when making revetment brick, and revetment brick finished product, which is neatly placed, to be stacked upon, and when river levee rebuilding construction passes through haulage vehicle
It is transported to construction site, revetment brick is from embedded shape, and muti-piece revetment brick can be connected as a plane and be laid in river levee slope
On face, need for revetment brick fractional layer to be laid in river levee slope surface according to engineering design plan (EDP), top layer mats formation with overburden soil
Revetment brick, plantation greening turf or short bushes, reduces water flow and other adverse circumstances on the revetment brick overburden soil of surface layer
Destruction to river levee, prevents erosion.
Specific governance flowchart is as follows, and mud is released from the river 1 before improvement and is re-fed into 2 in concentration basin by dredger,
Quenched be sent into device for dehydrating sladge waste 3 later is dehydrated in concentration basin 2, and dewatered sludge is sent into flat plate hydraulic machine 4 into shape
Brickmaking, manufactured brick are used as revetment brick 5 and use to get the river 6 to after clearing up.
