Abstract:

The sources and hazards of waste gas and liquid in the production of precipitated white carbon black in China were described in detail.It was pointed out that the direct emission of carbon dioxide waste gas and sodium sulfate waste liquid to the environment not only wastes resources and pollutes the environment,but also seriously restricts the sustainable develo-pment of the industry.Various methods of resource utilization of the two pollutants were described,which carbon dioxide could be converted to precipitate barium carbonate and light calcium carbonate,and sodium sulfate could be converted to industrial products such as barium sulfate and potassium sulfate and sodium sulfide.Through the analysis and comparison of various methods of resource utilization,it was suggested that the production enterprises of precipitated silica should cooperate with the barium salt industry for joint production,which would not only reduce the emission of “three wastes” and protect the environment,but also would be the best way of resource utilization of pollutants.And it has certain feasibility.

Key words: precipitated white carbon black, cleaner production, pollution analysis, sustainable development, resourceutilization
