Because steel slag has a certain alkalinity and a large specific surface area, it can be considered for adsorption treatment of wastewater. Zheng Lisheng et al. conducted research on using steel slag to treat chromium-containing wastewater and believed that steel slag has chemical precipitation and adsorption effects. For chromium-containing wastewater with a mass concentration within 300 mg/L, steel slag is added at a chromium/steel slag weight ratio of 1/30, and the chromium removal rate reaches 99. Wang Shilong et al. conducted research on using steel slag to treat zinc-containing wastewater, and found that for zinc-containing wastewater with a mass concentration within 200 mg/L, adding slag at a zinc/steel slag weight ratio of 1/30 can achieve a zinc removal rate of more than 98%. , the treated wastewater can reach the GB-8978-88 comprehensive sewage discharge standard. Steel slag can also be used to treat wastewater containing phosphorus and wastewater containing other heavy metals.
