摘要：
某精细化工厂生产医药中间体格列齐特粗品、氨基杂环盐酸盐和酰亚胺,产生高含氨、高含盐废水.采用凝聚沉淀-三效蒸发浓缩预处理后,与地面冲洗水、设备清洗水等废水混合后通过微电解+A2/O工艺处理,处理后废水总排放口COD、BOD5、SS、氨氮、总氮均达到《化学合成类制药工业水污染物排放标准》(GB 21904-2008)中表2要求,AOX达到《污水综合排放标准》(GB 8978-1996)表4中二级标准.

Abstract:
A fine chemical plant produces pharmaceutical intermediate:gliclazide crude,amino heterocyclic hydro- chloride and imide,releasing wastewater containing high ammonia and high salinity. After pretreated by flocculation-three effect evaporation and concentration process,and mixed with ground rinsing water and equipment cleaning water,the wastewater is treated by micro electrolysis+A2/O process. After the treatment,the concentrations of COD,BOD5,SS,ammonia nitrogen,total nitrogen at the wastewater total discharge outlet can meet the requirements specified in table 2 of the Discharge Standard of Water Pollution in Chemical Synthesized Pharmaceutical Industry(GB 21904-2008),and the concentration of AOX meets the requirements specified in table 4 of the second grade of the Integrated Wastewater Discharge Standard(GB 8978-1996).
