摘　　要：利用生物反硝化与树脂吸附的组合工艺对某农药生产企业生物滤池出水进行总氮去除处理。实验研究发现:生物滤池出水中的有机物作为反硝化脱氮碳源效果差,当外加碳源甲醇,停留时间为12 h,碳氮比为5∶1时,总氮去除率达到80%以上,出水总氮≤20 mg/L;反硝化出水经树脂吸附处理,处理能力为200 BV时,出水总氮低于15 mg/L。The combined process of biological denitrification and resin adsorption was used to remove the total nitrogen of the effluent from a company's biological filter.It was found that the organic matter in the raw water cannot be used as the carbon source for denitrification.When the reaction time was 12 h,methanol was the external carbon source,and the carbon nitrogen ratio(C/N)was 5∶1,the total nitrogen removal rate was over 80%,and the total nitrogen in the effluent was less than 20 mg/l.While the resin adsorption capacity was 200 BV,the total nitrogen in the effluent was less than 15 mg/L.
