ABR反应器处理高浓度头孢抗生素废水实验研究

抗生素类制药废水的有机污染物浓度高，可生化性差，微生物不易降解，处理难度很大。采用动态试验对厌氧折流板反应器（ABR）处理某头孢类制药厂废水进行了研究。结果表明，当进水CODCr负荷控制在2．67—3．0kg／（m^3·d），温度控制在35．4-0．5℃时，ABR对该废水CODCr的去除率可达在50％，且其可生化性得到了有效的提高，促进了废水进一步后续生化处理的运行稳定性。

Study on Treatment of Cephalosporin Wastewater by Anaerobic Baffled Reactor

Anti-biologic pharmaceuticals producing wastewater is characterized by its high concentrations of organic contents which are hardly degradable biologically. A lab-scale study on cephalosporin wastewater treatment by Anaerobic Baffled Reactor （ABR） was conducted. The results show that when the influent organic loading rate was 2.67 - 3.0 kg CODCr（m^3·d） Under controlled temperature of 35 ＋ 0.5 ℃, 50% of CODCr removal can be obtained and ABR could effectively improve the biodegradability of the wastewater. After being treated by ABR, the operational stability of aerobic process was promoted.
