1. Classification processing. There are three physical forms of waste: solid, liquid and gaseous. Haiwei Steel adopts a classification treatment method, which improves the processing efficiency and promotes the recycling of waste. The solid waste in steel production is mainly steel slag and water slag. Shanxi Wenshui Haiwei Steel has a special steel slag treatment plant and water slag storage plant to use the originally useless steel slag as raw materials for sintering and steelmaking, realizing the self-recycling of waste Digestion. Since water slag itself has extremely high use value, Haiwei Steel chose direct sales, which saved the cost of waste treatment and created new benefits. It can be said that it kills two birds with one stone.
2. Technological decontamination. The waste water and gas emitted during the production of the steel industry is a major and difficult issue in corporate waste treatment. In order to completely solve the pollution of wastewater and gas to the surrounding environment, Shanxi Wenshui Haiwei Steel introduced coarse particle separators and electrostatic precipitator technology. The turbid ring water generated during the production process first passes through the oil drain filter, then undergoes harmless evolution in the sedimentation tank and cooling tower, and finally becomes usable clean water. The treatment of waste gas is more complicated. Electrostatic precipitator, gravity dust removal, bag dust removal and cyclone dust removal are all in one, achieving the effective recovery and harmless emission of all waste gas.
