Example three:

based on the embodiment, the third embodiment is to perform functional improvement and upgrade on the pumice to obtain the phosphorus removal function:

the invention relates to a multifunctional glass pumice with a phosphorus removal function, which comprises the following preparation processes:

the raw materials comprise the following components in percentage by weight:

90% of glass powder;

2% of iron ore powder containing ferric oxide;

magnesite powder and quicklime mixture, 8%; wherein magnesite powder and quicklime each have 4 percent of each bit.

The raw materials are uniformly mixed, heated, sintered and cooled to form the multifunctional glass pumice with the dephosphorization function.

And (3) verification: the sintered pumice glass with the phosphorus removal function is used as an experimental group, and compared with the conventional common pumice glass as a comparison group, the pumice glass with the same weight is selected and put into a beaker, the same volume of treatment water with the same phosphorus content is poured, and then the phosphorus content of the treatment water solution is detected every 24 hours by using potassium dihydrogen phosphate solution defined in the national standard, so that the phosphorus removal rate is obtained:

	0h	24h	48h	60h
					comparison group	13.6	12.8	6.39	4.29
Experimental group	13.6	5.14	6.69	3.99

The comparative tests show that the phosphorus removal effect is more than twice of that of the original conventional pumice within 24 hours, so that the rapid phosphorus removal can be realized within a short time, and the phosphorus-containing components in various sewage such as rainwater can be reduced, so that the vegetation can be prevented from being burned by excessive phosphorus compound nutrients in the subsequent water supply process of the vegetation.

In detail, the components are as follows:

glass powder obtained by grinding waste glass in a glass production process, wherein the particle size of the glass powder particles is 10-100 mu m

Iron ore powder containing ferric oxide is formed by grinding iron ore;

the magnesite powder and quicklime mixture can be prepared according to the weight ratio of 1:1, and can also be selected according to actual bubbles and the pore diameters of the bubbles. The magnesite powder is a magnesium carbonate mineral, and can increase the number of bubbles in the sintered glass pumice, so that the number of micropores is increased after cooling, the weight is reduced, and the influence on the pore diameter of the bubbles is not obvious (the increase is less than 1 mm). And the quicklime can enlarge the pore diameter of the bubbles, and the quicklime and the bubbles both play a role in promoting foaming, but the effect of adding the quicklime is more remarkable in view of overall foaming. Therefore, when different types of products are fired, the different proportions of the two are selected as foaming additives.

Meanwhile, magnesite powder and quicklime are ground to have the particle size of less than 1pm to form ultrafine particles, the ultrafine particles refer to that the atomic number of the powder is correspondingly reduced along with the reduction of the particle size of the powder, and the proportion of the specific surface area and the surface atomic number to the total atomic number of the particles is gradually increased. When the size of the powder particles is small below a certain critical value, the properties of the particles may change abruptly, resulting in powder particles with properties that are significantly different from those of large particles or bulk materials. The critical dimension of the ultra-fine particles of the same material is different from the critical dimension of the ultra-fine particles of the same material, and the critical dimension required for the ultra-fine particles of the same material is different from the critical dimension required for the ultra-fine particles of the same material.

In the third embodiment, the pumice glass has a dephosphorization function, so that micro-current can be introduced while filtering and storing water to adsorb phosphorus-containing components in sewage, and the pumice glass has better purification capability and improves the purification effect.

And then, attaching the conductive solution to the surface of the sintered glass pumice (the glass pumice is common glass pumice, namely the glass powder and the foaming agent are sintered at high temperature).

There are two attachment methods:

firstly, spraying a conductive solution on the tiled glass pumice by a spray gun, so that the conductive solution is sprayed on the surface of the glass pumice and the inner wall of partial micropores, and meanwhile, in the spraying process, in order to ensure that the spraying is more uniform, the glass pumice can be repeatedly turned over or rolled, for example, the glass pumice is continuously sprayed with an organic solution in a vibrating or rolling state by a vibrating screen or a boiling bed, so that the spraying is more uniform;

soaking the glass pumice in the conductive solution, taking out after about one minute, wherein the soaking mode has low efficiency and insufficient surface uniformity compared with a spraying mode, and the conductive solution layer attached to the surface of the glass pumice has thicker thickness.

And finally, sending the glass pumice attached with the conductive solution layer into an oven, and drying at the temperature of 450 ℃ for 20min to ensure that the conductive solution is solidified on the outer surface of the glass pumice and the inner wall of the micropores to form a conductive layer.

In the fourth embodiment, the pumice glass has the conductive capacity, so that micro-current can be introduced while filtering and storing water, and the biological activity of microorganisms in micropores of the pumice glass is activated, so that the pumice glass has better biological purification capacity, and the purification effect is improved.
