Description

A kind of multiple-effect 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, 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.
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, be often combined them according to the difference of water treatment agent property.
