Description
Technical field
The present invention relates to water-treatment technology fields, and in particular to a kind of inorganic composite flocculant.
Background technique
Sewage is a kind of complicated, stable dispersion, and single flocculant can not often obtain satisfied treatment effect,
Therefore, Recent study personnel start to develop composite flocculation agent.It was verified that composite flocculation agent is shown better than single flocculant
Effect.Studies have shown that the flocculating effect of Inorganic/organic Complex Flocculent is more preferably, the replicating machine of Inorganic/organic Complex Flocculent
The main expected synergistic effect of reason is related, and chemical action occurs for pollutant impurity and flocculant in one side waste water, and flocculant is worn
Thoroughly with the functional group of destruction pollutant impurity, it is made to completely eliminate stickiness；On the other hand, flocculant passes through " bridging " principle,
The surface for being adsorbed on pollutant impurity particle is adsorbed on another pollutant impurity particle surface again, assembles by the glutinous pollutant that disappears
Impurity particle ultimately forms the spongy bulk floccule that can be easy to float.
Flocculant mainly divides inorganic, organic two major classes, and in addition there are microbial flocculants.Inorganic flocculating agent is cheap,
But can have an adverse effect to human health and ecological environment；Although organic polymer coargulator dosage is few, dross yield is few, wadding
Solidifying ability is strong, and wadding body can be easily separated, and oil removing and oil removal effect are good, but the residual monomer of this kind of high polymer is easy to cause rugged, cause
Cancer, mutagenesis, thus it is restricted its application range；Microbial flocculant is because being not present secondary pollution, and adsorption effect is good,
Easy to use, application prospect is expected, but at this stage using fewer.Therefore, currently used flocculant uses composite flocculation
Agent.
Different formulations, different proportion organic or inorganic composite flocculation agent flocculating effect exist very big difference, commonly
The composite flocculation agent content of material that makes pollutant eliminate stickiness it is excessive and the content of material that adsorbs pollutant is very few, pollutant
It can not be attached together completely, turbidity is still very high after sewage treatment；When make pollutant eliminate stickiness content of material it is very few,
And the content of material for adsorbing pollutant is excessively high, flocculant cannot be completely eliminated the stickiness of pollutant, can not be by all pollutions
Object aggregation is attached together, and turbidity of sewage removal rate is not high, and sewage treatment is not thorough.
