Use melting furnace three wastes a processing method, slag treatment 1, 2, water quenching slag recycled directly directly for cement raw material 3, made cast stone slag 4, use a waste for building and road construction materials, and farmland fertilizer, waste treatment and utilization of 1. Exposure to electric furnace flue gas purification 2. Semi-closed furnace 3. Enclosed furnace flue gas purification and energy recovery. Three, the comprehensive utilization of dust waste water processing and application of ferroalloy production wet dust removal ( Venturi scrubber) Will produce a large amount of sewage, wastewater contains a variety of harmful substances, direct emissions, will damage to the environment, and waste of water resources. Purification treatment, as well as protect the environment, and can make the water recycling, kill two birds with one stone.
