Description
Technical field:
The present invention relates to field of environment engineering, and in particular to a kind of processing method and processing device of riverway sludge.
Technical background:
Oneself increasingly influences the normal performance of the various functions such as flood control, water drainage, irrigation, water supply, navigation for river channel sedimentation, is extensive
Multiple river normal function, promotes the fast continual development of economic society, carries out channel cleanout dredging work.River is set to pass through improvement
Deepen, broaden, river water becomes clear, the working condition and living environment of the masses be improved significantly, reach " water is clear, and river is smooth, and bank is green,
The target of scape beauty ".River channel all there is a problem of seriously polluted mostly in China, and various regions water conservancy construction department has begun centering
River channel pollutant abatement technology expansion in-depth study simultaneously applies in practical improvement.
The mud cleared out in the river pulk of rural area is directly backfilling into farmland nearby mostly, this is also the past few decades rural area
Most common mode.Nowadays, this way is had quite a few drawbacks: part mud has heavy metal pollution, or containing a large amount of house refuses,
Building castoff, peasant household be unwilling to receive go back to field；After mud goes back to field, time several years is needed to air-dry, also needs secondary treatment after air-drying,
During this period, field can not plant, and government need to give peasant 1 to 2 year reimbursement for expenses in the form of rent etc..Coastal river and lake
The library pool, the mud cleared out have and are much transported to sea and topple over.This mode freight charges are expensive, and by tidal effect, mud is also
It is possible that by refunds inland river.River in city, mud often pollute larger, it will usually find nearby it is idle, completed
The soil of collection is stacked, and is waited after drying, then clear outward as architecture sediment, for filling.This mode takes up an area demand
Greatly, expense is also relatively high, and there are also the risks of secondary pollution.
The processing of mud is primarily referred to as stabilizing mud, minimizing, innoxious and recycling processing, generally
Including concentration (conditioning), dehydration, anaerobic digestion, aerobic sigestion, lime stabilization, burning, compost, desiccation and comprehensive utilization etc..
Currently, can be there are mainly three types of the mud disposition methods of large-scale engineeringization application: one, burning that (product of burning is used
In landfill or production building materials)；Two, land use；Three, it fills.Landfill processing cost is low, but takes up a large area, landfill
Gas, percolate are more and difficult.Incineration technology volume reduction significant effect, the available utilization of the calorific value of mud, but run at
This is higher, and there are problems that atmosphere secondary pollution.Anaerobic digestion techniques can recycle energy substance, but operational management is difficult
Degree is big, and successful case is few.Tradition machinery dehydrating effect is undesirable, can not achieve the deep dehydration requirement of mud, and exploitation is directed to
The method and apparatus of urban sludge processing is the important topic that current environment administers field.The present invention develops a kind of river silt
The processing method and processing device of mud realizes mud high-efficiency dehydration and stabilisation.
Summary of the invention:
In view of the above-mentioned deficiencies in the prior art, it is an object of the present invention to a kind of processing method and processing device of riverway sludge is provided,
Efficient removal mud moisture.
A kind of processing method of riverway sludge of the present invention, is achieved through the following technical solutions:
1) it, digs out, is collected in mud storage pool from bottom of river channel by mud；
2) mud is transported in the material bin above reactor tank from mud storage pool by sludge pump, passes through pan feeding
Bucket flows slowly into reactor tank, and the water that mud is sprayed in the high-pressure injection device below material bin in reactor tank is hit, and becomes silted up
Mud is smashed by high pressure water and impinges upon reaction top tank structure；
3) mixture of water and mud that, high-pressure injection device sprays flows into reaction pot bottom along reaction top tank structure, quiet
Layering is set, the water on upper layer is placed into cyclic water tank, the water source as high-pressure injection device；The mud of lower layer is fed to mechanical de-
On the filter plate of water installations, starting vacuum pump to be vacuum negative pressure condition below filter plate, starts the compression dress of mechanical dehydration device
It sets, compression processing is carried out to mud, for mud under the action of vacuum and compression set, removing moisture realizes desiccation.
The pressure of the high-pressure injection device injection high pressure water is 10-20MPa.
The mud flows into the flow velocity in reactor tank from the material bin of reactor tank as 10-20L/min.
Uniform filter opening is set on the filter plate of the mechanical dehydration device, and the aperture of the filter opening is 1mm.
The mechanical dehydration device internal system pressure is 1Kpa.
