【摘要】 针对某制药公司废水主要成分为DMF、三乙胺、四氢呋喃等,新建1座废水处理厂,采用化学氧化—兼氧—好氧—接触氧化处理工艺。该类制药废水含盐量较高,需经稀释后再进行生化处理,经生化处理后二沉池出水可达《污水综合排放标准》(GB 8978—1996)二级标准。处理工艺恶臭气体采用收集—预处理—低温等离子处理—后处理—高空排放工艺进行处理,处理后可达《恶臭污染物排放标准》(GB 14554—93)二级排放标准。更多还原

【Abstract】 Due to the fact that the major constituents of pharmacy production wastewater were DMF,triethylamine,tetrahydrofuran,and so on,a new wastewater treatment plant with the process of chemical oxidation-anaerobic-aerobic-contact oxidation was built for wastewater treatment.Because the high saline concentration in this kind of wastewater,it needed to be diluted before the chemical treatment.The effluent from the secondary sedimentation tank after the chemical treatment could meet the secondary grade standards of Integrated wastewater discharge standard(GB 8978—1996).The order gas from the wastewater treatment was treated by the process of collection-pre-treatment-low temperature plasma treatment-post treatment-high space discharge.After the treatment,the gas could meet the secondary discharge standards of Emission standards for odor pollutants(GB 14554—93).更多还原
