Strengthen the resource utilization of metallurgical solid waste and promote the green development of metallurgical industry

Environmental protection industry Metallurgical solid waste can also be used in environmental engineering. The results show that steel slag has chemical precipitation and adsorption. In the study of steel slag treatment of wastewater containing chromium, the removal rate of chromium reaches 99%. In the study of steel slag treatment of zinc-containing wastewater, the removal rate of zinc is more than 98%, and the treated wastewater meets the comprehensive discharge standard of GB897888. In the study of treating mercury-containing wastewater with steel slag, the removal rate of mercury reached 90.6%. The results of this study provide an effective way to solve Marine mercury pollution. Steel slag can also be used to treat wastewater containing phosphorus and other heavy metals. In addition, the high alkalinity of steel slag is conducive to the suppression of Marine red tide, which has a positive significance for Marine ecological governance.

China has carried out a lot of work on the comprehensive utilization of metallurgical solid waste and made many achievements, but the realization of the comprehensive utilization of metallurgical solid waste is not limited to the building materials industry, agriculture, ceramics industry and so on. The treatment and utilization of metallurgical solid waste involves a number of interdisciplinary fields, and more experts and enterprises are needed to participate in it.
