发酵类抗生素废水处理工艺及运行效果

介绍了内蒙古某抗生素废水处理厂的处理工艺流程、处理单元类型及其详细设计参数,通过对该污水处理厂半年内运行效果的调研,分析评价该污水处理系统的处理效果及出水指标;该水厂工艺流程对COD、TOC、氨氮、总氮、总磷、BOD和急性毒性的平均去除率分别为96.52%、95.83%、50.24%、55.20%、62.05%、98.52%和99.14%,COD、氨氮、总氮、总磷出水水质分别为477、438、556.7和7.69 mg/L,达到排放到城区下水道要求,园区内所有废水汇集到园区污水处理厂进行集中深度处理达标后排放水体。通过对该水厂工艺的介绍和水质分析,为我国抗生素生产企业面临的废水处理工艺类型选择及工程改造升级提供一定参考。

Process design and operation efficiency of an antibiotic wastewater treatment plant

The treatment process,main structures and design parameters of an antibiotic wastewater treatment plant in Inner Mongolia were described and analyzed with the operation efficiency in half year. The removal rates of COD, TOC, NH₃-N, TN, TP, BOD5 and acute toxicity were 96.52%, 95.83%, 50.24%, 55.20%, 62.05%, 98.52% and 99.14%,respectively. And COD, NH₄⁺-N, TN and TP of the effluent water was 477, 438, 556.7 and 7.69 mg/L. The effluent quality was up to the standard in the industria park. All wastewaters in the park were collected and treated in advance in the sewage treatment plant before discharged to natural water. This could provide some basis of the theory for upgrade of the antibiotic wastewater treatment process in China.
