Description
Technical field
This patent is related to a kind of industry for having excellent phosphor-removing effect, while having the functions such as flocculation, decolouring, COD removals concurrently
Waste water treatment medicament -- the technology of preparing of multiple-effect dephosphorization agent, belong to environmentally friendly water treatment agent field.
Background technology
The traditional phosphorus removing method of sewage treatment industry mainly has chemical precipitation method and microbial method.Chemical precipitation method it is basic
Principle is to add one or more of metal ions that precipitation can be generated with phosphate radical, by generating insoluble phosphatic side
Method so that phosphate radical removes from water.The conventional precipitating reagent of traditional dephosphorization method have calcium chloride, aluminium polychloride, bodied ferric sulfate,
The aluminium such as aluminum sulfate, alchlor, ferric trichloride, frerrous chloride, iron, calcium salt.Due to traditional dephosphorization method phosphor-removing effect not only with
The dosage of precipitating reagent is relevant, sewage remained after processing phosphorus concentration additionally depend on formed insoluble salt solubility product it is big
It is small, so, it is good selection using traditional dephosphorization method when the emission request to phosphorus is not high.It is but higher for emission request
Occasion, traditional dephosphorization method just can not meet requirement.
The content of the invention
The invention aims to overcome traditional dephosphorization agent phosphor-removing effect not reach emission request and the single disadvantage of performance
End, there is provided one kind both has good phosphor-removing effect, has flocculation, decolouring, the multiple-effect water treatment agent for removing COD and other effects concurrently again.
The formula and preparation technology of the present invention is as follows：
The cationic polymerization composition formula of table 1
The multiple-effect dephosphorization agent basic recipe of table 2
Cationic polymer preparation technology：
In the enamel or stainless steel cauldron with reflux condensate device and heating jacket, dimethyl diallyl is sequentially added
Ammonium chloride, diallylamine, glacial acetic acid, stirring is started, be heated to 82 DEG C, add part composite initiator, control reaction
Temperature is no more than 100 DEG C, when being cooled to 82 DEG C, adds part composite initiator, and after heating terminates, it is multiple to add remaining
Initiator is closed, after heating terminates, 95 DEG C is heated to and is incubated 2 hours, standing makes it be naturally cooling to room temperature, obtains cationic polymerization
Thing.
The preparation technology of multiple-effect dephosphorization agent：
In the reactor with heating and device for absorbing tail gas, water, hydrochloric acid and ferric trichloride are sequentially added, starts stirring, delayed
Slow to add calcium aluminate, reaction temperature meeting nature rises, when calcium aluminate adds and temperature rises to 80 DEG C（Do not reach 80 such as
DEG C, then heat temperature raising）, cationic polymer is added, is warming up to 90 ~ 95 DEG C, is reacted 4 hours, is cured 24 hours.
Technical key point is：The polymerization that cationic polymer participates in aluminium chloride ferrum is introduced, obtained product is not
Only there is excellent phosphor-removing effect, while have the function such as decolouring and COD removals concurrently.
Embodiment
Embodiment 1
In the reactor with reflux condensate device, dimethyl diallyl ammonium chloride cationic monomer 240kg, diene are added
The kg of propyl group amine 10, the kg of glacial acetic acid 8,82 DEG C are heated to, add composite initiator 0.2kg, controlling reaction temperature is no more than
100 DEG C, during after naturally cool to 82 DEG C, 0.2kg composite initiators are added, after heating terminates, add the compound initiations of 0.3kg
Agent, after heating terminates, it is heated to 95 DEG C and is incubated 2 hours, cationic monomer is made.60 parts of water of addition in another reactor, 100
