%X The caustic soda recycle and utilization were investigated in the present work.During the process of the preparation of high-carbon graphite from medium-carbon one,large amount of caustic soda were consumed.Consequently,alkaline wastewater was produced.The conventional lime causticizing approach was applied to recover the industrial material,i.e.,the caustic soda.The caustic soda recycling rate is up to 65.4%.Moreover,they could be reused to the graphite processing.Hence,the resources are recycled effectively by using this method.Also,the outlet water pH can meet the national emission standard.Most important is that it is possible to realize cleaner production in graphite processing.
