Guangfa Hero Post: "One piece of phosphide" attracted 10 million "rewards"!

Text ｜ "China Science News" trainee reporter Li Sihui Correspondent Qiu Jianshan

"We took out 10 million yuan in funds and sincerely invited various types of scientific and technological innovations across the country to actively participate in the unveiling list." At the list of Hubei Province phosphopide pollution prevention and comprehensive use of science and technology research on September 15th, the Hubei Provincial Department of Science and Technology related The person in charge released 5 "unveiled lists" topics, facing the "hero post" of Guangfa Technology across the country, solving the problem of prevention and control and comprehensive use of phospholose pollution pollution.

How much "grind" a piece of phosphide, why is it needed to send "hero posts" to the national research institutes and scientists? The "China Science News" interviewed Wang Yanxin, the president of the Chinese Academy of Sciences and the principal of the Chinese University of Geosciences (Wuhan), who had in -depth research on the phosphorus and chemical industry.

The effective utilization rate of phosphide gypsum around the world is less than 10%

"We must use the concept of emerging industries to correctly look at the development of the phosphorus chemical industry and promote the transformation and upgrading of the phosphorus chemical industry." Wang Yanxin introduced that phosphorus chemical is an important basic industry, which not only guarantees national food security, but also provides industrial enterprises with industrial enterprises. Basic raw materials. At the same time, phosphate chemical is also an emerging industry. The lithium iron phosphate produced by it is a key raw material in the field of power battery. The black phosphorus that is developing and tried is a advanced material similar to graphene. It is expected to play in new functional materials production and application. Key role.

"However, the development of the phosphate chemical industry is also facing ecological environment constraints." Wang Yanxin bluntly said, "Especially in the production process of wet phosphate production, a large amount of phosphopide is produced. Typical large solid waste. In addition to calcium sulfate, the main component of phospholosypsum also contains a small amount of piles of phosphorus, fluoride, organic matter and other impurities. The huge amount of phospholosaclene is not only occupied by a large amount of land, but also caused serious environmental pollution. The industry is mainly concentrated in the ecological environment sensitive areas that are in the middle and upper reaches of the Yangtze River. Whether the problem of phospholose pollution can be effectively resolved, which is related to the success or failure of the Yangtze River protection. "

Data show that in 2020, the amount of phospholosifying gypsum in my country was about 75 million tons, and the amount of phospholosaclene in Hubei Province was 29.96 million tons, ranking first in the country. Hubei is the largest province of phosphorus chemical industry in the country, and phosphorus is an important pillar industry in Hubei. The problem of "stuck neck" in the field of phosphorus chemical industry to realize the comprehensive utilization of phosphide gypsum and green development of the industry is one of the most prominent technological problems facing Hubei.

How difficult is the phospholoscopy gypsum? Wang Yanxin said that so far, the effective utilization rate of phospholol world for phospholosaclene is less than 10%. How to deal with low -cost disposal and large -scale use of phospholoside is the lack of mature technologies that can be used for reference, which is a problem that is urgent to resolve the ecological environmental protection and sustainable development of the phosphorus chemical industry.

Some organization innovation to crack the "card neck" problem

In order to further solve the bottleneck of comprehensive technical governance of phospholosypsum and promote the green and sustainable development of the phosphorus chemical industry, the Hubei Provincial Department of Science and Technology released five topics, namely "low -quality phosphate mineral reduction technology and demonstration", "phosphoric acid production process. "Key technologies and demonstrations", "Phosphorum alcohol ultra -soluble pure and clean production key technologies and demonstrations", "key technologies and demonstrations of phosphide gypsum co -selection and purification", "key technologies and demonstrations of millions of tons of phospholosypsum resource use" Social collection and unveiling plan, the funding support quota is 1 million to 2 million yuan/item, and the total funding is 10 million yuan.

Wang Yan's new analysis, the five "unveiled lists" topics, for the purpose of achieving large -scale consumption and comprehensive utilization of phospholosypsum, based on the "three modernizations" principles of solid waste treatment and disposal. System research, process purification, harmless treatment and resource use, etc., the subject research goals are clear and the indicators are advanced.

"Hubei sincerely invites national universities, scientific research institutions, science and technology enterprises, or the consortium of its composition to unveil the list. It is believed that through organizational innovation, Chinese scientists will be able to further improve the harmless disposal technology of phosphide gypsum and develop a number of costs lower. The new process, new technologies and new products with a wider range of application, higher market acceptance, and greater consumption, overcome the 'card neck' problem that affects the development of the phosphorus chemical industry. "Wang Yan is full of expectations.
