摘要
针对山东某医药产业园区生产废水高COD、高氨氮、高盐分和可生化性差等特点,设计采用蒸氨-MVR蒸发结晶-臭氧催化氧化-A2/O-深度处理工艺,处理水量为500 m3/d.工程实践表明,该工艺对COD、氨氮、总氮、总磷和SS的去除率分别达到了 97.1％、89.9％、85.9％、93.5％和96.3％,相应出水水质分别为358、27、52、0.62和40mg/L,出水水质满足GB/T 31962-2015《污水排入城镇下水道水质标准》中的A级排放标准.
Abstract
According to the characteristics of the wastewater in a pharmaceutical industrial park in Shan-dong province such as:high COD and ammonia nitrogen concentrations,high salinity and poor biodegradability,a combined process of ammonia distillation-MVR evaporative crystallization-catalytic ozonation-A2/O-advanced treatment was adopted,and the design treated water volume was 500 m3/d.The engineering practice showed that,the removal rates of COD,ammonia nitrogen,total nitrogen,total phosphorus and SS by the said process reached 97.1％、89.9％、85.9％、93.5％and 96.3％respectively,the effluent water quality met the requirement of A-level discharge standard of GB/T 31962-2015 Wastewater quality standards for discharge to municipal sewers.
