Description
Technical field
The invention belongs to water-treatment technology fields, and in particular to a kind of preparation method of modified copper water-supply pipe particle and its
Go the application on phosphate in water removal.
Background technology
Phosphorus is the important factor for causing body eutrophication, can be given by way of chemical precipitation, bioanalysis and absorption
Removal.Chemical precipitation method dephosphorization efficiency is high, but needs to add chemical agent, may will produce secondary pollution.Biochemical method is imitated
Fruit is unstable and the transfer of P form and position only occurs, and finally exists in the form of excess sludge.Absorption method dephosphorization by
It is widely used in the removal of phosphorus in Different Waters, dephosphorization efficiency depends on the selection of sorbing material.
With the city water treatment plant of the surface water such as lake, reservoir water source water intaking frequently with coagulation-precipitation-filtering-disinfection etc. one
Serial procedures remove all kinds of impurity in water removal, are being met《Standards for drinking water quality》（GB5749-2006）Water outlet
While also produce a large amount of sludge.Because of adding for the coagulant such as molysite, aluminium salt, the gold such as aluminium, iron, calcium are often contained in copper water-supply pipe
Belong to element, is directly discharged to environment there are potentially hazardous, recycling is then relatively difficult.Iron and aluminium in waterworks sludge is mostly with nothing
Stereotypic morphological exists, and carries out proper treatment to copper water-supply pipe, such as high-temperature calcination can make its surface form a kind of loose porous knot
Structure can be used as the phosphorus in sorbing material absorption water, realize " treatment of wastes with processes of wastes against one another ".
Invention content

The present invention adopts the following technical scheme that solve above-mentioned technical problem, a kind of preparation side of modified copper water-supply pipe particle
Method, it is characterised in that the specific steps are：
（1）Water supply plant dewatered sludge is ground into powder after natural air drying, and is run through 60 mesh metallic screens, and envelope is spare；
（2）By step（1）Treated copper water-supply pipe particle is 8 according to mass ratio with kaolin:3~7:2 ratio mixing, then
The spherical particle that grain size is 0.5-1.5cm is made in mixture plus water；
（3）By step（2）Obtained spherical particle is placed in 105 DEG C of baking ovens dry 2~3h, molding；
（4）By step（3）Spherical particle after molding is placed in 800 DEG C of Muffle kiln roasting 2h, is sealed after cooling；
（5）By step（4）Spherical particle after roasting is soaked in the hydrochloric acid solution of 2mol/L, is stood at room temperature for 24 hours；
（6）By the spherical particle distilled water flushing after salt acid soak to neutrality, it is placed in 105 DEG C of baking ovens and dries to constant weight,
It is final that modified copper water-supply pipe particle is made.
Further preferably, step（2）Described in copper water-supply pipe particle and kaolinic mass ratio be 3:1.
Application of the modified copper water-supply pipe particle of the present invention in going water removal on phosphate, it is characterised in that specific mistake
Cheng Wei：The content of life phosphate from sewage is 7.5mg/L before processing, and the dosage of modified copper water-supply pipe particle is every liter of life
Sewage adds 6g and is modified copper water-supply pipe particle, and the pH value of sanitary sewage is adjusted to 3, is shaken at room temperature in the rotating speed of 80r/min
120h, the content of Phosphorus in Domestic Wastewater with Pulverized hydrochlorate is 0.28mg/L after processing, and dephosphorizing rate 96.31% meets《Municipal sewage treatment
Factory's pollutant emission standard》（GB18918-2002）Emission request of the level-one A standards to phosphorus 0.5mg/L.
Operability of the present invention is strong, has stronger removal effect to phosphate from sewage, with traditional biological phosphorus removing method phase
Than having many advantages, such as that consumption power is few, requiring environmental condition recycling profit that is few, while helping to realize waterworks sludge
With.
