Description
Technical field
The application relates to sewage treatment area, particularly relates to a kind of equipment for separating liquid from solid and application thereof.
Background technology
In Modern sewage processing procedure, coagulating is the most extensive and indispensable important ring in water treatment applications
One of joint.Its technique is widely applied to tap water and produces and in Industrial Waste Water Treatments engineering.
Coagulating is actually a considerably complicated physical-chemical reaction process, recognizes coagulation the most clearly
Course of reaction includes three phases: condense, flocculate, absorption caught by net.1, coacervation process includes: add flocculant, wadding in sewage
Solidifying agent and the pollutant in sewage, such as colloid, microgranule etc., collide rapidly and to carry out charge neutrality/adsorption-condensation de-steady, de-steady microgranule
Mutually coalesce and form primary micro-floccule granule.2, flocculation process is then that primary micro-floccule granule continues absorption pollutant, is formed
The process of the sedimentation floc particle thick and closely knit, proportion is bigger.3, alumen ustum floccule body net is caught adsorption process and is included: alumen ustum is wadded a quilt with cotton
Solidifying body i.e. flco, flco is to be made up of flocculant, and the high-molecular complex that flocculant produces after hydrolysis forms adsorption bridging
Associating, adsorb pollutant, such as colloid, microgranule etc.；" build bridge " between pollutant, thus promote to gather, be a kind of irreversible
Assemble.Flocculant mainly neutralizes in some water with electropositive or electronegative group and is difficult to point with elecrtonegativity or electropositive
From pollutant, such as colloid, microgranule etc., reduce the electromotive force of pollutant so that it is play pendulum, and utilize its aggregation property
These granules are concentrated, forms alumen ustum floccule body together with flocculant.
The most universal sewage disposal coagulating flow process is: sewage enters coagulation reaction tank, and segmentation adds various coagulations
Medicament carries out the mixed reaction of speed, after allowing floccule body capture pollutant, then carries out sewage precipitating filtering, the wadding after solid-liquid separation
Solidifying body does not recycles after forming mud.In actual operating process, the addition of coagulated agent and pollutant levels in sewage
Linear ratio relation the most clearly, therefore, in order to ensure the treatment effect of sewage, the most inevitably needs to add
The coagulated agent of excess, this is the phenomenon generally existed during practice produces.This not only causes the significant wastage of coagulated agent, and
And also directly increase the cost of sewage disposal.
Additionally, coagulating process includes three phases as previously mentioned, the these three stage is also alumen ustum flocculation in fact
The three phases that body is grown up.In the these three stage, the potential change of alumen ustum floccule body adsorption process and pollutant purification situation are such as
Shown in Fig. 1, the alumen ustum at agglomeration phase, positively charged or negative electricity generates, and with pollutant collision, neutralization, makes pollutant de-steady, figure
1a；Thereafter, at flocculated stage, alumen ustum adsorbs pollutant further, forms the sedimentation floc particle that proportion is bigger, Fig. 1 b；Finally,
Alumen ustum floccule body carries out net and catches absorption, Fig. 1 c the pollutant such as colloid, microgranule.After three phases, coagulating is basically completed,
Most pollutant in sewage are separated, it is thus achieved that clear water.During these three, the alumen ustum energy of adsorption to pollutant
Power the most gradually weakens, during as in figure 2 it is shown, alumen ustum just generates, and Fig. 2 a, containing a lot of pollutant in sewage, its energy of adsorption
Power also gradually forms, therefore, it is possible to well adsorb various pollutant；In the alumen ustum maturation period, Fig. 2 b, alumen ustum can adsorb respectively
Plant easily absorption, the pollutant of even easily absorption；In the last alumen ustum ageing step, Fig. 2 c, the pollutant in water subtract in a large number
Few, wherein only have seldom part and be difficult to the pollutant being adsorbed.In the alumen ustum ageing step, first, the absorbability of alumen ustum is more weak；
Second, the pollutant levels in water are the lowest, the most easily collide reaction with flocculant, thus the most no longer hold
Easily adsorbed by alumen ustum floccule body.Although increasing the consumption of coagulated agent further, i.e. increasing the amount of alumen ustum, to a certain extent can
Enough allow water outlet limpider；But, in current technological level, this has also basically reached a bottleneck, in waste greatly
While coagulated agent, water outlet also cannot be made limpider.For in theory, water outlet can carried out a coagulating；
But, in practice, this is equivalent to have employed double processing cost, and cost performance is the lowest, essentially without so operation.
