Ardealite be in production process of phosphoric acid with sulfuric acid treating phosphorite stone when a kind of industry byproduct for generating, often produce
1.0 tons of phosphoric acid will generate 4.5-5.0 tons of ardealite.And ardealite is mainly handled with stockpiling at present.2015, China's phosphorus
Gypsum discharge capacity adds up volume of cargo in storage up to 300,000,000 tons up to 80,000,000 tons.Data are shown, are such as stored up by general industrial solid waste
Ardealite, 100 hectares of stockyard can store up ardealite about 2500-3000 ten thousand steres, be subjected to producing 500000 tons of phosphoric acid plant per year（I.e.
2,500,000 tons of ardealite of year discharge）10-12 produces 800000 tons of phosphoric acid plant per year（I.e. year discharges 4,000,000 tons of ardealite）The phosphorus of 6-8
Gypsum discharge capacity is such as calculated by stockpiling 10-12, and every ten thousand tons of ardealite storage yards take up an area about 0.4 hectare, and investment is about 27-33
Wan Yuan.Moreover, containing the harmful substances such as phosphate, sulfate in ardealite, during long-term stockpiling, to soil, surface water,
Underground water, air have different degrees of pollution.And the annual ardealite volume of comprehensive utilization in China is only about 10,000,000 tons at present, phosphorus
The volume of comprehensive utilization of gypsum is much smaller than the discharge capacity of ardealite.Ardealite not only occupies soil, but also polluted environment, and ardealite is tight
Restrict the sustainable development of China's sulphur dioxide of phosphor chemical industry again.Therefore, recycling, the scale comprehensive utilization skill of ardealite are developed
The Protection significance of art, utilization and ecological environment to Industrial Solid Waste is great.
