摘要
某化工厂以化学合成法生产医药中间体,产生的废水中含有大量有机物及高浓度的氮磷,原有处理工艺处理废水后已不能达标排放。对存在问题进行分析研究,改进了原有工艺,采用MAP+ABR+A2/O工艺处理该制药废水。实际运行结果表明,工艺改进后出水各项指标均达到《化学合成类制药工业水污染物排放标准》(GB 21904—2008),可为高氮高磷制药废水处理提供参考与借鉴。
A chemical plant has used chemical synthesis method for the production of pharmaceutical intermediate.However,the produced wastewater contains a lot of organic substances and highly concentrated nitrogen and phosphorus. The original wastewater process could not reach the wastewater discharge standard. Through analyzing the existing problems and improving the original technology,MAP ＋ABR ＋A2/O process is applied to the treatment of pharmaceutical wastewater. Actual operation results show that： after the technological improvement,all the indexes of the effluent can meet the requirements specified in the Discharge Standards of Water Pollutants for Pharmaceutical Industry Chemical Synthesis Products Category（GB 21904—2008）,being able to provide reference for the treatment of pharmaceutical wastewater containing highly concentrated nitrogen and phosphorus.
