新闻背景:山东海化集团,是全国最大的海洋化工生产和出口基地。尽管守着大海,海化集团仍自觉运用循环经济理念,实现了“一水六用”。即用海水放养贝类、鱼虾等海产品;海水蒸发后的初级卤水放牧卤虫;中级卤水先送纯碱厂、硫酸钾厂供工艺冷却;在工艺冷却过程中吸收了化工废热的中级卤水送 News background: Shandong Haihua Group is the largest marine chemical production and export base in the country. Despite guarding the sea, Haihua Group still consciously used the concept of circular economy to achieve “one water and six uses.” That is, seawater is stocked with shellfish, fish and shrimps and other marine products; brine in the primary brine evaporates with Artemia; brines are sent to soda ash plants and potassium sulphate plants for process cooling; and intermediate brines are absorbed by chemical waste during the process cooling process.
