制藥工程畢業設計的意義?
①在新藥研發中最大安全劑量的統計學研究,可以選擇數理統計教師承擔畢業設計指導工作。
②對于今后從事藥品營銷的畢業生,可以選擇市場營銷相關專業的教師指導畢業設計,做些藥品銷售策略或市場分析等內容;
③讓環境保護相關專業教師指導制藥廢水處理研究的畢業設計內容等等,此方法也克服了專業師資不足的問題。總之,做好制藥工程專業的畢業設計實踐教學工作是提高專業教學質量的關鍵環節,也是學生對本科時期學習的基礎理論和專業課程的檢驗。

This graduation project is the design for a Hubei pharmaceutical wastewater treatment process of treatment plant. Main task is to complete the design calculation of this?? pharmaceutical wastewater treatment plant's treatment process.
The flow of the wastewater in this design is 20000 m3/d. the water quality is the antibiotic-wastewater. It belongs to a high concentration organic wastewater. it has a more pollution and it's the one of difficulties of the industrial wastewater treatment. Therefore it needs to be treated before discharge. The water quality of influent before being treated are listed as follows: COD = 5000mg / l, BOD = 2750mg / l, SS = 2400mg / l, =185 mg / l,Color=500. while the water quality standard of effluent are listed as follows Correspondingly:? COD 300mg / l, BOD 100mg / l, SS 150mg / l., ? 50 mg / l,Color 80.
According to the characteristics of the wastewater quality,Using the coagulation settler, hydrolysis acidification tank, UASB reactor and SBR reactor as the main structure for wastewater treatment. After pre-treatment(including the coagulation settler and hydrolysis acidification), the wastewater is improved biochemical treatment ability,and also enables the higher concentration of SS and colloidal substances having a effective removal, so as to reduce the operating load of the follow-up treatment process.In later stages, after pre-treatment of wastewater organic load remains high, so using the UASB and SBR process, that the anaerobic and aerobic processes to further processing to make the water purification.
The water will meet second national water quality level by this combination process.
Keywords: Pharmaceutical wastewater; Process design; Pre-treatment; UASB reactor;SBR reactor
