A total of 14 units of scientific research institutes, colleges and universities, industry associations, inspection institutions, production enterprises and user representatives.

My country's fluorosol has become the fourth largest industrial gypsum after phosphopide, flue gas desulfurization gypsum, and titanium gypsum, and more than 60%of them have not been used well. In recent years, with the enhancement of environmental awareness and comprehensive use of resources, there have been many technologies and cases of comprehensive use of fluorosol in China. Flo gypsum can be used as raw materials for the production of gypsum building materials. The quality and ingredients of the fluoride gypsum are uneven, which causes difficulties to effectively convert the fluoroscin into the plaster material that meets the quality requirements of the production of plaster building materials. In order to regulate the quality of fluoride, improve the quality of fluoride gypsum and market recognition, promote the comprehensive utilization of fluoride plaster resources, and issue the "Revision of the Second Batch of Industry Standard Systems in 2021 and the Foreign Language Edition project of the General Office of the Ministry of Industry and Information Technology The File of the Plan (the Department of Industry and Information Technology [2021] No. 159) documents, led by the China Architectural Materials Federation of Gypsum Building Materials Branch and the Institute of Architectural Materials Industry Technology Institute of Technology (Project Plan number: 2021- 0535T-JC).

5. Inventory how to deal with phosphopyrets in various countries: stacking methods are not desirable.Phosphorprophropladium is the main by -product of wet phosphoric acid production. Usually, every 1 ton of wet phosphate is produced, which will produce 4.5 to 5 tons of phospholol. It is difficult to deal with. Stove.

According to statistics, there are about 185 million to 215 million tons of phospholpyplasium worldwide each year, while the world currently has about 3 billion to 4 billion tons of phospholosypsum stacked. The stacking of phospholosypsum not only occupies the land, but also causes the richness of the water body. With various problems, the treatment of phospholpaceous has gradually become a pain point for phosphorus chemical enterprises in various countries.

Regarding the stack, the US Environmental Protection Agency believes that phosphatet heroxy is a radioactive waste. In order to reduce the emissions of other radioactive nucleo, phosphlo gypsum is required to be stacked on the ground. Due to the restrictions of the radium-226 concentration, the US Environmental Protection Administration currently stipulates that only phospholoshen is used in agriculture in a small amount.

In fact, after World War II, phospholol was used in road construction, construction of parking lots and agricultural production. As early as the 1980s and 1990s, countries around the world had conducted a lot of research on phosphol her gypsum. Dr. Brian Birky, a Florida Industry and Phosphoric acid Institute, said that there are currently 50 million to 60 million tons of phospholosypsum every year in the world, and the global view of phosphopide is also "stacked in the past. "Formation" is a waste of valuable resources that can be available.

01)

In Spain, phospholpyrophytes have been used in agricultural production for more than 70 years. Related Spanish studies measured the amount of cadmium absorption of the crop after the soil was applied to the soil, and simulated the performance of phosphide gypsum in the soil for decades. The research results show that the use of phosphide is safe in agriculture, and it is also regarded as a legal fertilizer.

02)

The phosphide is weakly acidic and can be used as soil improvement agent, especially the improvement of salt -alkali land. It improves soil affected by magnesium and low -integrated calcium. At the same time, it can effectively reduce soil plate knots and enhance soil water retention. On the saline -alkali land in Kazakhstan, the output of conventional cotton area is about 1.0 ~ 1.5 tons/hectares. The results of the relevant test show that after a 4.5 tons of phosphor gypsum per hectare, the cotton yield can be increased to 2.5 ~ 3.0 tons/hectares; 8 tons of phosphor gypsum per hectare can be increased to 3.0 tons/hectares. It can be seen that the cotton yield after using phosphopide shows a significant advantage.

03)

An Indian fertilizer company Paradeep Phosphats LTD is re -processed by phosphlo gypsum to produce granular reinforced trace elements (magnesium, zinc, boron) fertilizer and reinforcement compound fertilizer. The fertilizer products after phosphopide will help improve soil fertility Increase the absorption and utilization of crops to nitrogen, phosphorus, and potassium, and finally increase crop yield.

04)

Canada cooperates with the forestry sector to mix the phospholosifying and soil at a ratio of 9: 1 to make "artificial soil" for afforestation.

05)

China has a compulsory circular economy. In terms of zero abandonment policies, the government has also provided the use of phosphorplasyhplasyhposcin use for phosphorus chemical enterprises. If it does not comply, enterprises will face high fines. Dr. Brian Berki believes that this is not an adequate supervision method, but it has also promoted China's research and development and application of phospholol. China Lufu Group uses more than half of phospholosypsum for agricultural and industrial construction, or recycles ammonium sulfate, calcium carbonate, iodine, etc., and gradually achieve the goal of zero waste.

Many studies have found that phosphide can be used as fertilizer and soil improvement agent in agriculture; in industry, it can be used as grassroots materials and building materials; Essence In addition, phospholpyrophyte can also be used as a raw material for glass and ceramics, and can also participate in some marine projects. There are many safe and beneficial purposes of phospholpyplasium, and many countries are trying or have applied phosphopide to many aspects.

Dr. Brian Berki said that the UN 2030 Sustainable Development Agenda covers 17 sustainable development goals and 169 sub -goals. Many of them can be achieved by phospholosypsum. Phosphorum is an important resource recognized by the UN European Economic Commission.

In summary, phosphopide stacked is not a sustainable choice, and it cannot meet the requirements of social, environmental and economic aspects. The fertilizer industry plays a vital role in national and global food security. The unreasonable processing method of "stacking" phospholosypsum to increase the burden on the fertilizer industry, and constructive supervision will bring a win -win results. The transformation of "phospholosypsum into available and valuable phospholosacyps is converted to the United Nations' sustainable development goals.
