Abstract
The invention discloses eco-friendly pumice for sponge-type city construction and a preparation method thereof. Glass powder, bentonite powder, zeolite powder and magnesite ore powder are mixed to form a powder compound and the powder compound is subjected to high temperature foaming and annealing treatment so that the eco-friendly pumice is obtained. The glass pumice obtained through the preparation method has a professional water purification capability. Through a porous structure and a water purification material, the eco-friendly pumice has filterability, adsorptivity and ion exchange ability and can realize purification of any polluted water. After water purification, the phosphor-containing glass pumice can be used as a soil conditioner for a soil improvement material so that resource cycle and recycle are realized and waste is avoided.
Description
Technical field
The present invention relates to glass pumice field, be specially a kind of environmental protection pumice being applied to sponge urban construction and preparation method thereof.
Background technology
Along with the appearance of " sponge city " new ideas, glass pumice becomes builds the indispensable base mateiral in sponge city, compare other material and there is obvious use advantage, the appearance of glass pumice can be described as the technology of an epoch revolution, environmental protection pumice is widely used, the science such as water storage, draining, water purification, waste water circulation recycling for " sponge city " is harnessed the river and is had great significance, because its special vesicular structure purification to water quality has low, the effective feature of cost.But in the prior art, " sponge city " purifies waste water, and what utilize is the dense porous structural advantages of glass pumice, the physical chemistry advantage of some water-purifying material itself is then only utilized at conventional purge sewage, wherein wilkinite and zeolite are because having good ion-exchange capacity and absorption property, be used to remove multiple pollutant, magnesium oxide is utilized phosphoric adsorbed in waste water etc., these methods need a large amount of natural resourcess, treatment cost is also very high, although glass pumice has the low advantage of water purification cost, but be also only limitted to the advantage of its constructional feature, performance space not larger at present.
Summary of the invention
In order to solve the problem, the invention provides a kind of environmental protection pumice being applied to sponge urban construction and preparation method thereof, make the glass pumice material of dense porous structure itself namely possess water purification function, thus make glass pumice play faster, efficient, wide water purification space.
The present invention's concrete technical scheme content is as follows:
Be applied to an environmental protection pumice for sponge urban construction, form powder admixtion by glass powder, bentonite in powder, zeolite powder, mineral powder of magnesite, obtain through high temperature foaming, anneal.
Preferably, described powder admixtion proportioning is: glass powder 70 ~ 90, bentonite in powder 2 ~ 10, zeolite powder 2 ~ 10, mineral powder of magnesite 2 ~ 10.
Be applied to a preparation method for the environmental protection pumice of sponge urban construction, its step is as follows:
1, mixed with wilkinite, zeolite, giobertite by the material of glass powder processed, obtain powder admixtion through being milled to more than 150 orders, its proportioning is: glass powder 70 ~ 90, bentonite in powder 2 ~ 10, zeolite powder 2 ~ 10, mineral powder of magnesite 2 ~ 10;
2, above powder admixtion is put into process furnace, 400 ~ 500 DEG C are preheated to 5 ~ 10 DEG C/min from room temperature, maintain after 20 ~ 50 minutes, then 800 ~ 850 DEG C of foaming 30 ~ 50 minutes are warming up to 5 ~ 15 DEG C/min, then be cooled to 600 ~ 700 DEG C with 5 ~ 10 DEG C/min and stablize 20 ~ 40 minutes, then the demoulding is annealed to room temperature below 500 DEG C.
Beneficial effect of the present invention: the environmental protection pumice 1, utilizing the present invention to obtain uses for sewage purification specially, in improvement sewage, effluent cycle recycling, not only can utilize glass pumice cell texture, and contain wilkinite, zeolite and magnesium oxide because of it, add ion-exchange capacity and the absorption property of glass pumice itself, make purifying water effect better.
2, the environmental protection pumice containing phosphorus obtained after utilizing water purification of the present invention, namely can be used as soil improvement agent, for soil improvement material, forms resources circulation recycling.
