厌氧复合床处理抗生素废水的生产性启动研究

Study on the Start-up of the Full-Scale Upflow Blanket Filter Treating Antibiotic Wastewater

摘要: 处理抗生素废水的厌氧复合床反应器单体有效容积为500 m³,根据反应器中有机物降解和细胞合成的关系,建立了进料有机负荷模型M_n=(1+k)^n-1M₁和进料容积负荷模型N_n=(1+k)^n-1N₁.根据启动过程中细菌的生长特性和进料有机负荷模型的计算,提出了厌氧复合床反应器启动运行的进料负荷技术方案,成功地进行了厌氧复合床处理抗生素废水的生产性启动.

Abstract: The effective volume of an upflow blanket filter (UBF) unit for treating antibiotic wastewater is 500 m³.Based on the relationship of organic substances biodegradation and cell synthesis in UBF,a mathematical model of feed organic loading, M_n=(1+k)^n-1M₁ ,and a mathematical model of feed volume loading rate, N_n=(1+k)^n-1N₁,were established.Based on calculation of bacteria growth feature and feed organic loading model in the start-up process, a feed loading technical scheme was put forward for the start-up of a full-scale UBF reactor and the start-up was successfully made for treatment of antibiotic wastewater by the UBF.
