摘要
针对3-氰基吡啶氧化-氯化-水解法合成2-氯烟酸生产过程中产生的废水,采用膜萃取法结合多相催化氧化的工艺进行处理,回收了废水中的有用物质,废水经处理后达到国家废水排放标准中的三级标准。
A new process which oombined the membrane extraction with heterogeneous catalytic oxidation was used to treat the wastewater from 2-chloronicotinic acid production. After treatment, the useful materials were recovered, and the wastewater was meet the national emission standard.
