Description
The application is application number：2015103610371, the applying date：On 06 27th, 2015, denomination of invention：A kind of multiple-effect
The divisional application of water treatment agent and preparation method thereof and method for treating water.
Technical field
The present invention relates to the technical field of water process, more particularly to a kind of multiple-effect water treatment agent and its preparation method and application
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, processing
The advantages that 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 be precipitated 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 independent with self-contained
Processing system, can also be combined with other processing unit processes, as pretreatment, intermediate treatment and final process mistake
Journey, it may also be used for the concentration process before sludge dewatering, improve the dewatering of sludge.
The species of water treatment agent can generally be divided into inorganic water treatment agent, organic water treatment agent and microorganism water process
Agent, and in actual applications, often they are subject to according to the difference of water treatment agent property compound.

Son measures the problems such as water treatment agent difference more organic with adsorption bridging ability.
The more inorganic water treatment agent of organic polymer water treatment agent has and by salt coexists is influenceed smaller, water treatment agent dosage
It is small, sinking speed is fast, produce the quantity of slag it is few, disposable the advantages that.But due to organic polymer water treatment agent generally existing monomer
Residual toxicity, higher selectivity, it is expensive the defects of, limit its extensive use to a certain extent.
Satisfied treatment effect generally can not be obtained to the sewage system of complexity using single water treatment agent, thus it is compound
