Background technique
The sludge of sewage treatment plant substantially has: three kinds of materialized mud, biochemical sludge, Physiochemical and biochemical mixing sludge etc..It is various
Sludge has certain difference to the adaptation of dewaterer, selects inorganic flocculating agent and organic anion to be configured to aqueous solution and waste water is added
In, compression double electric layer will be generated, the suspended particulates loss of stability in waste water is made, micelle object, which agglomerates, increases particle,
Form floccule body, alumen ustum.Floccule body is detached from aqueous phase precipitation after growing up to certain volume under the effect of gravity, to remove waste water
In a large amount of suspended matters, to achieve the effect that water process.
For run-of-the-mill concentration in 50~500mg/L, the less high particle precipitating of concentration of suspension belongs to flocculation sedimentation, such as
Suspended matter precipitating in coagulating sedimentation, sewage treatment in water engineering in primary sedimentation tank belongs to this type.During flocculation sedimentation,
Since particle mutually collides.It agglomerates the settling velocity that becomes larger to continue to increase, therefore particle settling velocity is actually to change.Flocculation sedimentation particle
Settling velocity refers to that particle precipitates average speed.In horizontal sedimentation tank, it is a curve that particle, which precipitates track, and is different from freely sinking
The linear motion in shallow lake.It is not only related with particle settling velocity in the removal rate of sedimentation basin endoparticle but also related with precipitating available depth,
The influence that column precipitator wall precipitates suspended matter is not only considered, it is also contemplated that influence of the pillar height to deposition efficiency.Flocculation sedimentation
It is the process that particulate matter makees flocculation sedimentation in water.In water after dosing coagulant, the wherein colloid and discrete particles of suspended matter
Flock is generated under the interaction of molecular force and they collide with each other cohesion in infall process, and size and quality are continuous
Become larger, settling velocity is continuously increased.The alumen ustum formed after dosing coagulant in the surface water, the organic suspended matter in sanitary sewage, activity
The phenomenon that flocculation sedimentation can all occur in precipitation process in sludge.
The common type of country's sludge dewatering equipment has at present: centrifugal, strainer formula, helical ring an official document or note formula and plate and frame.Precipitating
The dehydration of sludge, the selection and proportion operation of flocculant are very crucial, but processing equipment in the prior art and technique are using
In respectively have advantage and disadvantage, including bad adaptability, returned sludge is more, and backwash water amount is big, highly energy-consuming, high revolving speed cause noise greatly with

Specific embodiment
The utility model principle is that flocculation sedimentation is the process that particulate matter makees flocculation sedimentation in water.It adds in water
After coagulant, wherein the colloid of suspended matter and discrete particles generate flock under the interaction of molecular force and in infall processes
In they collide with each other cohesion, size and quality constantly become larger, and settling velocity is continuously increased.The removal rate of suspended matter depends not only on
Settling velocity, and it is related with depth of precipitation.The alumen ustum formed after dosing coagulant in the surface water, it is organic outstanding in sanitary sewage
The phenomenon that flocculation sedimentation can all occur in precipitation process in floating object, activated sludge.Precipitating is generated not when chemically reacting
The substance of solution where being dissolved in reactant is exactly precipitating removal under the effect of gravity.According to the property, concentration and wadding of suspended material
Solidifying performance, precipitating can be divided into: natural sedimentation, flocculation sedimentation, region precipitating.The suspension tears 5000mg/L or more of domain precipitating,
Concentration is higher, and the sedimentation of particle is by other particles effects around, and relative position remains unchanged between particle, and it is total to form an entirety
With sinking, there is clearly water sludge interface between primary water.There is region precipitating in secondary sedimentation tank and sludge concentration tank.
