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).
