摘　要：以改性活性炭作为吸附剂处理农药嘧啶杂环废水，讨论了改性活性炭的投加量、吸附时间、pH值等因素对羟基嘧啶类污染物的处理效果的影响，并通过好氧生化验证吸附对废水生化效果的影响。结果表明，改性活性炭吸附效果较未改性活性炭效果好，其适宜的吸附条件为：投加量为3%、pH值为4、反应温度为20℃，搅拌30 min后废水中2-二乙基氨基-6-甲基-4-羟基嘧啶（简称嘧啶醇）浓度从520 mg／L 降至50 mg／L以下，COD从2 070 mg／L降至1 000 mg／L以下。通过生化实验证明，改性活性炭吸附处理嘧啶醇废水使其生化性明显提高，COD去除率从50%提高至80%以上，且该浓度水平下的嘧啶醇对微生物基本无影响。

Abstract：The effects of loading, operation time, temperature, and pH value were discussed in the treatment of pesticide heterocyclic wastewater using modified activated carbon, and the effect of the wastewater by adsorption on aerobic biochemical treatment was verified. The results showed that the modified active carbon exhibited the better adsorption ability than the unmodified one. Conditions including 3% modified active carbon dosage, pH value of 4, reaction temperature of 20℃, and stirring time of 30 min were the optimal treatment condition. The concentration of 4-hydroxy-2-diethylamino-6-methylpyrimidin was reduced from 520 mg/L to 50 mg/L, and COD was reduced from 2070 mg/L to 1000 mg/L. Biochemical experiment proved that biochemical property of waste water was improved obviously after treated using modified activated carbon. COD removal rate was increased from 50% to 80%, and the concentration level of 4-hydroxy-2-diethylamino-6- methylpyrimidin had no effect on microorganism.
Key words：adsorption; waste water of 4-hydroxy-2-diethylamino-6-methylpyrimidin; modified activated carbon; biodegradability
