摘　　要：针对碳氮比小于7的污水,其碳源不能满足硝化与反硝化的要求这一问题,通过改变SBR工艺的运行方式、调解工艺参数等技术手段,使其能够达标处理此类工业废水,并通过某淀粉厂的工程实例进行了验证:采用改良的SBR工艺可以对低碳高氮污水进行有效的处理。The insufficient carbon can＇ t meet the requirement of nitrification and denitrification if the carbon nitrogen ratio of wastewater is less than 7. This kind of wastewater can be treated with SBR process to meet the discharge standard by changing operation mode and parameters. It is verified by a starch factory wastewater treatment project that modified SBR porcess can treat low carbon nitrogen ratio wastewater efficiently.
