广东东莞康民制药公司环保工程设计方案——广东东莞康民制药公司废水处理方案设计广东东莞康民制药公司废水处理方案设计摘要在近几年来，在制药行业的发展过程中，制药废水的产生量增大，废水中的污染物含量高，可生化降解性较差，水质水量变化大，是难处理的工业废水之一。制药废水中的难降解有机物含量多，其中具有较强的毒性，可以通过食物链富集与积累，对人类的健康和生态环境的影响是非常严重的。所以生产过程中的废水必须经过处理后达标排放。广东东莞康民制药公司采用山梨醇二步发酵法生产维生素 C，发酵类废水来源于发酵、提取、转化、精制过程。日产2000 吨废水，其中废水指标有：COD=12500mg/L、BOD5=4000 mg/L 、SS=180 mg/L 、NH3-N=140 mg/L、PH=3。针对此类废水设计污水处理工艺，参考国内制药废水处理方法和经验，设计污水从格栅到调节池提升泵至水解酸化池，再进入 IC 反应器，A/O 池脱氮和曝气池，再经过二沉池沉淀后出水。出水后的水质符合制药行业废水排放标准《发酵类制药工业水污染排放标准（ GB21903-2008）》 新建企业水污染排放浓度限值。关键词：制药废水；污水处理；发酵类制药；维生素 C 北京理工大学珠海学院 2020 届本科生毕业设计Design of wastewater treatment suitable technological process in Guangdong Dongguan Kangmin pharmaceutical companyAbstractAlong with development of Chinese pharmaceutical industry in the last year, the pharmaceutical industry produces so much wastewater. The wastewater that generated in pharmaceutical factory consists in a high pollution content, poor biodegradability, a large fluctuation of water character and flow. It is the mostly treated by biologic processes. There are many refractory organics in pharmaceutical wastewater, most of them are toxic, which can through the accumulation and enrichment of food chain and is affected badly on human health and ecological environment. Thus, the wastewater must be treated and discharged to the standard. Guangdong Dongguan Kangmin pharmaceutical company uses two-step fermentation of sorbitol to produce vitamin C. And t...
