Description
Technical field
The present invention relates to a kind of sludge treatment equipments, and in particular, to it is a kind of for sludge carry out concentration and it is quenched
Sludge condensation and modifying device, and further relate to the method handled sludge using the sludge condensation and modifying device.
Background technology
When sewage plant treated sewage, a large amount of sludge will produce.The mud granule of these sludge is in micron dimension, moisture content
It is very high, containing a large amount of organic principle, and substantially it is in colloidal generally 99.2% ~ 99.6%.The sludge high to this moisture content
It is transported and is stored all extremely difficult, this is because the volume of the high sludge of this moisture content is usually larger, therefore will produce
Expensive transport and carrying cost.In addition, this sludge is difficult to thorough desiccation under conditions of natural storage, and need to occupy
A large amount of valuable land resources store these sludge for a long time.Moreover, these sludge usually all contain heavy metal, harmful bacteria
Deng so that if with conventional mode（Such as natural storage or landfill）If being handled, the serious of environment is often led to
Pollution.In order to preferably handle disposing sludge, the moisture content for reducing sludge by sludge condensation is needed, the body of sludge is reduced
On the other hand product is convenient for carrying out at subsequent processing sludge on the one hand reduce transport and the carrying cost of sludge
Reason.In the prior art, sludge is concentrated generally by gravity concentration method, Bubble-floating Method and centrifugal concentrating method.
Gravity concentration method is that sludge is transported to sludge concentration tank, makes sludge settling to pond by way of natural subsidence
Bottom, and supernatant is correspondingly discharged.It is extremely grown however, this gravity concentration method using natural subsidence takes, generally requires length
Sedimentation separation can be completed up to 10 hours or more times.In addition, long time-consuming and the sludge formation for being deposited in bottom of pond is caused to be detested
Discharge standard is not achieved to cause dewatered P content in sludge higher in oxygen environment.In Chinese utility model patent
A kind of sludge concentration tank is proposed in CN205011601U, by being aerated and stirring the contact to increase sludge with oxygen, from
And reduce the release of phosphorus in sludge.But the effect due to being aerated and stirring so that sludge is more difficult to through natural subsidence
Mode concentrates and supernatant is accordingly discharged.Therefore, although the program reduces the release of phosphorus in sludge, but causes sludge dense
The contracting time is elongated, and efficiency is lower, and the moisture percentage in sewage sludge after concentration is also higher.
Bubble-floating Method and gravity concentration method are on the contrary, be so that mud granule is enclosed micro air bubble and float up to the water surface, then with scraping
Plate scrapes thickened sludge into mud drainage slot, and sludge water is then flowed out from bottom of pond.However, this method equally exists time-consuming longer problem.
It is required in addition, this method has mud granule degree, that is, mud granule degree cannot be too big, and bubble, which is otherwise difficult to be utilized, makes dirt
Mud floats.And centrifugal concentrating rule needs carry out in the Centrifugal concentrators being specifically manufactured, not using solid, liquid proportion in sludge
Together, there are different tendency to drift aways, muddy water is thus detached, to achieve the purpose that concentration.However, centrifugal concentrating method needs to use
Complicated and expensive special equipment, thus higher expense can be caused.
In addition, in order to which processing is effectively performed in the sludge high to moisture content, other than being concentrated to sludge, it is also necessary to
It is quenched to sludge progress for the characteristic of sludge, in order to processing such as subsequent mechanical dehydration and desiccation.This is because sludge has
There is very strong hydrophily, the binding force of moisture and mud granule in sludge is very strong.By putting into doping, thus it is possible to vary
The property of sludge destroys the structure of sludge colloid, the affinity with water is reduced, so as to improve the dewatering of sludge.So
And in the prior art, the characteristic all not having in the equipment for carrying out concentration to sludge for sludge carries out sludge
Quenched function.This has severely impacted the subsequent processing of sludge, results in the decline of sludge treatment capacity, increases and be produced into
This.
Therefore, in the field handled sludge, there has long been a desire for that be capable of providing a kind of device, can to sludge into
Row concentration and quenched, and floor space is small, can greatly improve thickening efficiency and shorten concentration time, obtains unexpected
Effect, meanwhile, it is simple in structure, easy to clean.It may also be desirable to it is capable of providing a kind of device, it can be according to quenched requirement
The amount of thickened sludge is adjusted, so that the amount of thickened sludge is reduced, it is to be conducive to carry out quenched.
