Embodiment 1

[0029] Directly use waste water to settle solid waste (hereinafter referred to as sediment) to melt glass, and the composition of the weight percentage of sediment includes: SiO 2 : 56.16%, Al 2 o 3 : 21.27%, CaO: 7.03%, Fe 2 o 3 : 0.42%, MgO: 0.31%, Na2 O: 7.42%, K 2 O: 0.12%, SO 3 : 5.32%, La 2 o 3 : 1.95%. The specific production method is as follows:

[0030] A planetary ball mill is used to grind the sediment until the powdery particles pass through a 16-mesh sieve. Put the ground sediment particles into an alumina crucible, heat them in a high-temperature furnace to 1350°C and 1400°C respectively, keep them warm for 1-2 hours, then pour them into a mold, and anneal them in an annealing furnace at 650-700°C1 -2h, cool down to room temperature with the furnace.

[0031] The performance indicators of the glass obtained at different melting temperatures are as follows:

[0032]

Embodiment 2

[0034] Directly use waste water to settle solid waste (hereinafter referred to as sediment) to melt glass, and the composition of the weight percentage of sediment includes (wt%): SiO 2 : 46.16%, Al 2 o 3 : 24.27%, CaO: 6.03%, Fe 2 o 3 : 0.45%, MgO: 0.32%, Na 2 O: 9.42%, K 2 O: 0.15%, SO 3 : 8.32%, La 2 o 3 : 1.96%, C u O: 0.98%, Ni 2 o 3 : 0.94%. The specific production method is as in Example 1, and the properties of the glass obtained are similar to those in Example 1.

Embodiment 3

[0036] Glass is manufactured according to the composition formula in Example 1. The difference is that the preparation method is: grind the sediment to powdery particles, heat the ground sediment particles to 1500° C., and keep the temperature for 1 hour. The obtained glass liquid is obtained by using water The quenching method is directly made into glass powder. The obtained glass powder can be used as a raw material for glass manufacturing, or as a raw material for other fields such as ceramic glaze and sintered glass-ceramics.

Abstract

The invention discloses a method for recycling and reusing solid waste. The solid waste comprises oxide of silicon, aluminum, calcium and sodium; the solid waste is directly made into glass or is made into glass with other raw materials. The invention further discloses glass prepared by using the solid waste as a raw material. The solid waste can be the solid waste belonging to any fields of the oxide of silicon, aluminum, calcium and sodium. The solid waste is directly verified or is mixed with other cheap minerals and then is verified; the utilization ratio of the solid waste is up to 100 percent and 60 percent respectively; the obtained products can meet the general requirements; the products can be recycled completely; and multiple aims of changing waste into treasures, protecting environment and realizing sustainable development can be fulfilled.

Description

Technical field [0001] The invention involves a method of recycling for solid waste, which specifically involves a method made of a solid waste into glass and glass made of solid waste as raw materials. Background technique [0002] There will be a large amount of solid waste in industrial production and life.Solid waste refers to the solid and semi -solid waste substances produced in production, consumption, life and other activities in a wide sense.Animal corpses, metamorphic foods, human and animal feces, etc.The accumulation and emissions of solid waste will not only occupy places, but also pollute the environment. At present, there is no method of effectively recycling it.Studies have found that some solid waste contains oxide components such as silicon, aluminum, calcium, sodium, and these ingredients are common components of glass manufacturing.Because the glass can be recycled multiple times, the inorganic solid waste can be used as raw glass to solve their pollution and ...
