Specific embodiment
Embodiment 1
A kind of oxygen sustained release, the preparation method for inhaling phosphate material, are comprised the following steps that：
(1) it will carry after iron particle charcoal, calper calcium peroxide particle, portland cement, quartz sand are well mixed and obtain compound
It is standby；
Preferably, carry iron particle charcoal to be prepared from by raw material of walnut shell particle, specific preparation method is as follows：
Walnut shell particle is placed in Fe3+Concentration is impregnates more than 12 hours in 0.5-1.0mol/L maceration extract, then by the core of dipping
Peach shell particle carbonizes 80-100min under 480-520 DEG C of anoxia condition, the grain diameter of obtained load iron particle charcoal
For 1-2mm；The particle diameter of described calper calcium peroxide particle is 90-110 mesh, and purity is 70-80%；Described portland cement is selected
425 portland cements；The particle diameter of described quartz sand is 1-2mm.
Preferably, it is 1 to carry iron particle charcoal, calper calcium peroxide particle, portland cement, the mass ratio of quartz sand：4：2：

Preferably, the mass ratio of compound and water is 9：1.
(3) material after hydration reaction is granulated, the grain diameter after granulation is 1-2cm, then in natural conditions
At least 24h is air-dried down, and sealing preserve is standby.
(4) before engineer applied, air-dried particle is put into 5 in the sodium alginate soln that mass fraction is 2~3%~
After 10min, taking-up is used immediately.
Embodiment 2
The test of the material phosphor-removing effect of the present invention is as follows：
Tested by Staticadsorption experiment, when initial phosphorus concentration is 5mg/L, 50mg/L, liquor capacity 100mL, oxygen delays
Release, inhale phosphate material weight when being respectively 0.81g, 0.85g, 1.55g, 1.62g, after 4 hours equilibrium adsorption capacities such as table 1 below, 2.

As can be seen from Table 1, 2：The material is respectively provided with preferably absorption effect to the phosphorus of low concentration in solution and high concentration
Really.
Embodiment 3
The material of the present invention is as follows to simulation river dephosphorization, the test of oxygen release effect：
Load 10cm bed mud in river respectively in 2 groups of analogue reactors, bed mud overlying water depth is 40cm, the 1st group of (blank
Group), the closed reactor air suitable for reading that reduces covers oxygen influence, the 2nd group of (experimental group), inflated with nitrogen immediately after inflated with nitrogen deoxidation 10 minutes
After deoxidation 10 minutes, 400g is added, oxygen sustained release thick covering 2cm inhales phosphate material, and the closed reactor air suitable for reading that reduces covers oxygen
Influence, 0, is measured by sampling overlying water total phosphorus and overlying water in analogue reactor in 3,6,9,12,15,18,21,24,27 days respectively
Middle dissolved oxygen concentration.As a result below figure 1, shown in Fig. 2.
As can be seen from Figure 1：Oxygen sustained release is not added, inhale the reactor of phosphate material because anoxic causes the release of sedimentary phosphate
The concentration of phosphorus in overlying water is gradually risen, and adds the material, because oxygen discharges, under aerobic condition, phosphorus release is suppressed,
And the material makes the concentration of phosphorus in reactor overlying water on a declining curve to the suction-operated of phosphorus.
As can be seen from Figure 2：Dissolved oxygen concentration in oxygen sustained release, the reactor overlying water of suction phosphate material is not added to level off to
Zero, and the material is added, because oxygen continues slow release, quickly rise reaches saturation, later stage dissolved oxygen to early stage dissolved oxygen concentration
Also close to saturation.
