Chromium salt industry, "second five" development plan has been put forward "specific targets in production scale, product variety, technology and other aspects, so that our country really become powerful chromium salt production" goal. During the "Thirteen Five", China chromium salt industry is still according to the "large-scale, large-scale, rational distribution" of industrial policy guidance, the only way to go clean production.

 

Chromium salts on the basis of the product is sodium dichromate. Production of sodium dichromate mainly calcium roasting process, the production process will produce large amounts of chromium waste. Containing toxic hexavalent chromium slag and strong carcinogenic calcium chromate, on the ecological environment and people's lives and health pose a huge threat. And because it is difficult to form a scale, "three wastes" treatment, technology research and development in a short time, some companies are unwilling to invest more funds for environmental protection construction, technology development and equipment updates. To solve the pollution problem chromium salt industry, during the "Thirteen Five", China chromium salt industry must at the same time management of chromium residue left over from history, and comprehensively promote clean production technology, reducing the amount of chromium slag produced from the source. Therefore, we should accelerate the promotion of non-calcium roasting, potassium-based sub-molten salt liquid phase oxidation method mature clean production technology in the industry; at the same time, speeding up the oxygen of ferrochrome base system sodium chromate, aerodynamic flow of the continuous liquid phase oxidation tower and other industrial applications a new generation of cleaner production technologies.

 

In promoting clean production process, on the one hand to strict industry access standards, improve trade barriers, in order to avoid blind investment, so that the advantages companies can transform existing business of production through technological innovation, acquisitions, restructuring and other ways to achieve cleaner production, It is transformed into environmentally friendly chromium salt production enterprises and create a market atmosphere. On the other hand, further build-out schedules and exit mechanisms and relevant supporting policies of backward production capacity, while clearly encourage technology, energy conservation and the promotion of specific technical measures to further enhance the industrial concentration, promoting the upgrading of industrial technology, in order to achieve " chromium salt production and large-scale, large-scale, rational distribution of "industry development objectives for system security.

 

Currently, we are in an era of change, the traditional manufacturing industry is facing many challenges from new technologies, new ideas, new formats. Vigorously develop clean production technologies, chromium salt industry, but also to adapt to the new era, new environmental efforts through the following four aspects.

 

First, expand the chromium salt varieties and applications. To accelerate the development of a trivalent chromium salt production process (such as chromium sulfate, chromium chloride, chromium formate), vigorously develop the market demand is about increasing the chromium nitrate, chromium fluoride, new technology, acetic acid chromium, hexavalent chromium caused avoid labor hygiene and environmental protection. Increase the chromium salt used in the field of wood preservative.

 

The second is to continue to promote large-scale production of chromium salt. Through competition, mergers, alliances, optimize the combination, survival of the fittest, etc., to promote advanced technology and competitive advantage chromium salt enterprises mergers and acquisitions, to further improve the level of large-scale production, improve production efficiency and reduce the cost of consumption, so that our chromium salts more competitive on the international market.

 

The third is to promote the chromium waste treatment technology commercialization. Increase the intensity of chromium waste treatment, support grasp chromium waste resource processing patent technology chromium salt factory, conducted chromium waste treatment market, commercial operation, and gradually improve the ecological environment.

 

Fourth, the healthy development of the chromium salt industry needs the strong support of national policy. Government departments through industrial policy planning, strict control of new chromium salt projects, and encourage and support enterprises in the industry clean production of new technology in the capital and policies, new technological transformation. In "Thirteen Five" late, to achieve cleaner production technology capacity can reach more than 95 percent, making China the world's largest producer of chromium salts chromium salts become a manufacturing power.
