Problems solved by technology

[0009] For river and lake water, farm water, landscape water, etc., which cannot be transported to sewage treatment plants, the common treatment method for this type of water is physical adsorption, which absorbs and degrades pollutants in the water body by adding filter materials, thereby purifying the water quality. Commonly used filtration The material has activated carbon, but the cost of activated carbon is relatively high, and the economy of activated carbon regeneration method has become the main bottleneck restricting the wide application of activated carbon in wastewater treatment.

Abstract

The invention discloses a foamed glass material for purifying water, and a preparation method thereof. Waste glass bottles undergo a series of treatments through special techniques to form the foamedglass material for purifying water, that is foamed micro-porous silicon pumice with an aperture of 1-4 mm, a water absorption rate of 5-10%, a stress of 1200-3000 N and a specific gravity of 0.5-0.8 g/ml. A foaming mixture is calcined at a high temperature to prepare the foamed glass material, and the foaming mixture includes 90-93 wt% of glass powder, 0.4 wt% of seashell powder having a particlesize of 2-4 mm, 0.6 wt% of seashell powder having a particle size of 1 mm or less and 0.2-1.0 wt% of activated carbon. The foamed microporous silicon pumice has the advantages of durability, high performances, non-toxicity, harmlessness, non-radioactivity, good chemical stability, good corrosion resistance, good weather resistance, insolubility and non-degradability, and the ammonia nitrogen, biochemical oxygen demand, chemical oxygen demand and other indicators of sewage treated with the foamed glass material are significantly reduced.

Description

technical field [0001] The invention relates to the technical field of foamed glass materials, in particular to a water-purifying foamed glass material and a preparation method thereof. Background technique [0002] my country is a country with severe drought and water shortage. Although my country has a large amount of water resources, due to the large population, the per capita water consumption is low, and the water resources that can be used as drinking water are limited; while industrial wastewater, domestic sewage and other wastes enter rivers, lakes, seas and other water bodies, exceeding the self-purification of water bodies Pollution caused by water pollution will lead to changes in the physical, chemical, and biological characteristics of water bodies, thereby affecting the use value of water, endangering human health or destroying the ecological environment, and causing deterioration of water quality. Due to various reasons, the water of rivers, lakes and farms in...
