Nano CaCO3 is an excellent filler,widely used in plastics,paper making,coating,chemical building materials and other industries.The project uses limestone and anthracite as the main raw materials to produce CaO,through the carbonation process to produce nano-CaCO3.On the basis of engineering analysis,the main production and discharge points and the main pollutants produced in the production process of the project were determined.According to the relevant environmental protection policies and technical requirements,the corresponding feasible measures for prevention and control of environmental pollution are put forward.All pollutants can be discharged up to the standard,properly treated and disposed of,and related suggestions and considerations are put forward.
