Description
Technical field
The present invention relates to sewage treatment fields, and in particular to a kind of water treatment agent, preparation method and water treatment agent processing
The method of fire demand water.
Background technology
Fire demand water is commonly stored in fire water box, for providing water source during fire-fighting.Since fire demand water is quiet
Set and be stored in fire water box, standing time relatively long after, will produce a large amount of algae, either bacterium is easy to block pipeline or water
Pump, influences to use.
The method of sewage disposal at present has very much, mainly for trade effluent and sanitary sewage, pollutant in trade effluent
It is numerous, it needs to carry out alignment processing according to practical pollution condition.Generally existing algae or thin in sanitary sewage and trade effluent
The pollution of bacterium, generally use Physical, chemical method or biological degradation method remove the pollutant in sewage.Biological degradation method cost
It is higher and more harsh to environmental requirement, be not suitable for large-scale promotion.
The applying date is on November 20th, 2014, and application No. is the Chinese patents of 201410664075.X to disclose a kind of sewage
Inorganic agent, preparation method and applications, the raw material of sewage-treating agent includes mainly magnesia, zeolite, sulfate, alkali in the patent
Agent, polymer coagulant when treated sewage, are needed certain density sewage-treating agent being added in sewage and be stirred, using
Separation removal solid sediment.Conventional sewage processing method is similar with the above method, but for fire demand water, algae and
Bacterium is major pollutants, and fire demand water stands storage, and when encountering dangerous situation, connection fire protection pipeline can be used directly,
It is comparatively laborious using above method removal pollutant, be not suitable for the processing of fire demand water.
Invention content
The object of the present invention is to provide a kind of water treatment agent, have and inhibit alga microbial growth, reduces COD in water and contain
The characteristics of amount.
The present invention above-mentioned technical purpose technical scheme is that：A kind of water treatment agent, including with
The raw material that lower weight fraction indicates is made：30-40 parts of high temperature active aluminium oxide；45-60 parts of bactericidal composition；Slow releasing composition

S4, water treatment agent is prepared：Modified high temperature active aluminium oxide is stirred 20-30min in slow releasing composition, is obtained after dry
To water treatment agent.
Using above technical scheme, bactericidal composition and slow releasing composition are prepared respectively in advance, high temperature active aluminium oxide changes
Property when, high temperature active aluminium oxide first impregnates at room temperature, then is increased to 60-80 DEG C, improves bactericidal composition in high temperature active oxygen
Change the dipping effect in aluminium hole.High temperature active aluminium oxide is modified by bactericidal composition, and further in its periphery, cladding is slow
Composition is released, the compactness of water treatment agent is improved, it is easy to use.
Further, mixing speed is 80-100r/min in step S2.
Using above technical scheme, melamine and polyvinyl alcohol mix under the above mixing speed, reduce obtained slow
It releases composition and generates bubble.At the same time it can also retain the viscosity of slow releasing composition, facilitate film forming.
Further, mixing speed is 150-200r/min in step S3.
Using above technical scheme, when high temperature active aluminium oxide impregnates in bactericidal composition, under above-mentioned stirring condition
It is mixed, the mixed effect of bactericidal composition is more preferably.
Further, mixing speed is 100-120r/min in step S4.
Using above technical scheme, in modified high temperature active aluminium oxide periphery bundled slow-releasing composition, in above-mentioned stirring
It is carried out under speed, in order to avoid generating bubble, influences covered effect.
A further purpose of the present invention is to provide a kind of method for being used for above-mentioned water treatment agent to handle fire demand water, tool
There is persistently to inhibit algal grown and permanent antibacterial.
The above-mentioned purpose of the present invention is achieved by the following technical programs：A kind of above-mentioned water treatment agent is for handling fire-fighting
With the method for water, include the following steps：
Water treatment agent, which is added in fire demand water, is stirred 30-60min, and the addition of water treatment agent is 20-40g/L；Fire-fighting is used
Filter screen is arranged in the exit of water, and the mesh number of filter screen is 40-50 mesh.
When handling fire demand water using the above water treatment agent, water process is added when fire demand water being perfused in fire water box
Agent can inhibit water body in fire demand water to grow algae bio.Meanwhile filter screen being installed in the exit of fire demand water, in order to avoid
Larger impurity enters pipeline in water body；Meanwhile water treatment agent can assist delaying the intensity of a fire under the action of water pump with water flowing
Sprawling.
Water treatment agent can also after be added, water treatment agent may be added in advance with algae bio in fire water box at this time
After be stirred 30-60min, the algae bio in fire water box of degrading.If after water treatment agent saturation, water can also be replaced in time
Inorganic agent.
In conclusion the invention has the advantages that：
1, water treatment agent uses nucleocapsid, high temperature active aluminium oxide that can both provide larger ratio as core active substance
Surface area can be with the algae bio in assistant degradation water body for loading bactericidal composition；Outside high temperature active aluminium oxide according to
Secondary cladding bactericidal composition and slow releasing composition further increase the bactericidal property of water treatment agent, and decompose algae bio
Performance；
2, raw material used by water process all has preferable flame retardant effect, and when using fire demand water, water treatment agent can also be made
For fire retardant, auxiliary fire extinguishing.
