A method to improve the activity of stainless steel slag

The present application discloses a method for improving the activity of stainless steel slag, which relates to the technical field of comprehensive utilization of resources. The method for improving the activity of stainless steel slag includes the following steps: placing hot stainless steel slag in a hot soaking pit or a slag pot, and hot soaking and spraying water for cooling to 100°C - 1000°C; introducing carbon dioxide in the first stage (pressure 0.1 - 0.5 Mpa, time 0.5 - 2 hours) into the container, and spraying water synchronously (the amount of sprayed water is 0.3 - 0.7 times the mass of the slag); then introducing air (pressure 10 - 15 Mpa, time 0.5 - 1 hour); then introducing carbon dioxide in the second stage (pressure 0.2 - 0.6 Mpa, time 1 - 2 hours), and spraying a small amount of water synchronously (the amount of sprayed water is 0.03 - 0.08 times the mass of the slag); after cooling, highly active stainless steel slag is obtained. With the collaborative design of staged gas introduction and spraying water for cooling, the content of free calcium oxide in the stainless steel slag is less than 2%, and the activity index reaches the standard of primary steel slag powder, greatly improving the resource utilization rate. At the same time, the fixed emission reduction of carbon dioxide is achieved, which helps with resource recycling and low-carbon development.

This invention relates to the field of slow-release fertilizer technology, specifically to straw-based slow-release organic fertilizer and its preparation method. The slow-release organic fertilizer includes an organic fertilizer core loaded with organic matter and nitrogen, phosphorus, and potassium nutrients using straw biochar as a carrier, and a slow-release coating covering the core. The slow-release coating is a cross-linked network formed by phytic acid cross-linking a hydroxyl polysaccharide substrate through phosphodiester bonds. Each phytic acid molecule forms an average of 1.5-3 phosphodiester bonds, with the remaining phosphate groups remaining as free phosphate groups and coordinating with iron and / or zinc. The phosphodiester bonds constitute the hydrolytic substrate of rhizosphere phosphatase. When crops are phosphorus deficient, the phosphatase secreted hydrolyzes the cross-linked bonds, causing the coating to uncross-link, thereby increasing the nutrient release rate with increasing phosphatase activity and simultaneously releasing trace elements such as iron and zinc. This allows nutrient release to adaptively match the crop's phosphorus deficiency requirements. The nitrogen release rate in still water over 28 days meets the national standard for slow-release fertilizers, and significantly improves the phosphorus accumulation and nitrogen fertilizer utilization rate in phosphorus-deficient soils.
