摘　　要：氨基酸是制药业的重要产品,伴随其生产过程会产生大量的发酵废液。该文对异光氨酸生产过程中所产生的高浓有机废水(实际生产废水)进行了厌氧生物处理的静态与动态实验研究。结果表明,在35℃,进水pH6.4～7.4,停留时间10h的情况下,最大有机负荷为8kg(COD)/m^3·d,沼气产生率6.3L/kg(COD),COD去除率≥80％。在正常操作状态下,污泥负荷最高可达3.6kg(COD)/kg(VSS)·d,进水COD浓度可达15000mg/L。Anaerobic treatment of high concentrated organic wastewater has been studied. The wastewater was produced in the isoleucine production process. The result of static and dynamic experiments showed that the removal rate of COD was≥ 80%, and gas production rate was about 6.3L/kg (COD). The operation conditions were: temperature 35℃, pH value of influent 6.4- 7.4, operation could be maintained under high concentration of organic impact, organic concentration was 15 000 mg(COD)/L.
