| abstract |
The invention discloses a prevention and control material for underground sewage and/or polluted soil treatment and a preparation method and application thereof. The prevention and control material is composed of the following components in parts by weight: 30-60 parts of red mud, 20-40 parts of molten steel slag , 10-30 parts of blast furnace slag, 5-10 parts of coal gangue, 5-10 parts of fly ash, 6-10 parts of curing/stabilizer, 4-8 parts of adsorbent and 4-6 parts of activator. Using red mud, molten steel slag, blast furnace slag, coal gangue and other solid wastes and wastewater as the main raw materials, not only the solid waste utilization rate is high, the production process is simple, and the cost is low, but the prepared solid waste-based control materials are resistant to As, Pb, Cr , Cd, Zn and other heavy metals and organic pollutants have good curing effect and high removal rate. |
