The method for treating water of the multiple-effect water treatment agent.
Background technology
In water treatment field, flocculation sediment is a kind of conventional processing method, and it has, and simple to operate, cost is low, handle
The advantages of effect is good.The mechanism of action of flocculation is commonly considered as having compression double electric layer and charge neutralization, macromolecule water process
The adsorption bridging effect of agent, the volume of flco sweep precipitation etc..The process of flocculation is the process of colloidal solid loss of stability, glue
Body material and small suspension grain are gathered into larger particle, so as to be easy to precipitate from liquid.Adding water treatment agent can be with
Accelerate this mechanism, absorption of these aggregates to the various impurity of dissolving can be greatly enhanced, advantageously in water
The purification of matter.
Water treatment agent is widely used in raw water and sewage treatment area, can reduce the sense such as turbidity, colourity of raw water
See index.A variety of macromolecule organics, some heavy metals and radioactive substance are removed by water treatment agent, both can be certainly into independence
Processing system, can also be combined with other processing unit processes, be used as pretreatment, intermediate treatment and final process mistake
Journey, it may also be used for the concentration process before sludge dewatering, improves the dewatering of sludge.

Advantage, be successfully applied in the various handling processes of feedwater, industrial wastewater and municipal sewage (including pretreatment, middle
Reason and advanced treating), it is increasingly becoming main flow water treatment agent.But due to inorganic water treatment agent exist hydrolytic instability, relative point
The problems such as son amount and the poor more organic water treatment agent of adsorption bridging ability.
The more inorganic water treatment agent of organic polymer water treatment agent has is influenceed smaller, water treatment agent consumption by salt coexists
Small, sinking speed is fast, produce the quantity of slag it is few, it is disposable the advantages of.But it is due to organic polymer water treatment agent generally existing monomer
The defect such as residual toxicity, higher selectivity, expensive, limits its extensive use to a certain extent.
Satisfied treatment effect can not generally be obtained to complicated sewage system using single water treatment agent, thus it is compound
