Background technology
Flocculation process is indispensable key link in sewage treatment process.During sewage disposal, often need
Flocculant is added, so that the suspended particulates in sewage is gathered and becomes larger to form floc sedimentation, to make the coagulation of particle.Flocculated principle is such as
Under：Positive (negative) electrical group is carried in flocculant, can neutralize in water and electrically be difficult to the particle detached with negative (just), is dropped
Its low potential, and using aggregation property these particles are concentrated, cotton-shaped coagulating sedimentation is formed, and pass through physics or chemistry side
Method is separated.
Conductive agent is added in the meeting having in existing flocculant, and its object is to, to electron transmission, make to flocculate by conductive agent
The charge generated in journey is transmitted to floccule surface by conductive agent, and the charge inside floccule can be also transmitted to by conductive agent
Floccule surface, it is easier to which the balance for breaking sewage system improves flocculated speed (flocculation efficiency).But, it has been found that
Partial flocculation efficiency around flocculant containing conductive agent is to be improved, but the flocculating and purifying of entire sewage disposal system
Rate (i.e. removal rate) is not improved but, or even is declined so that is needed to add more flocculants and be can be only achieved original wadding
Solidifying purifying rate, increases economic cost, loses more than gain instead in this way.
