Compounds interaction on the biodegradation of n-butanol and sec-butanol mixture in a composite bead biofilter was investigated. The biodegradation rate of compounds in the exponential growth phase and stationary phase for the single compound and two compounds mixing systems was determined. The microbial growth rate and biochemical reaction rate of two compounds decreased with increasing compound inlet concentration for the single compound system. The microbial metabolic activity of sec-butanol biodegraded in the microbial growth process and biochemical reaction process was inhibited as n-butanol was introduced. This inhibitive effect was more pronounced at higher n-butanol inlet concentration and lower sec-butanol inlet concentration for the two compounds mixing system.
研究了复合珠状生物滤池中亚硝酸菌对 n-丁醇和仲丁醇混合物生物降解的相互作用。测定了单一化合物和两种化合物混合体系在指数增长期和稳定期的化合物生物降解率。对于单一化合物体系，随着化合物入口浓度的增加，两种化合物的微生物生长速率和生化反应速率降低。当引入正丁醇时，微生物生长过程和生化反应过程中降解的仲丁醇的微生物代谢活性受到抑制。对于两种化合物混合体系，在较高的正丁醇入口浓度和较低的仲丁醇入口浓度下，这种抑制作用更为明显。
