大邦(湖南)生物制药有限公司废水主要来自发酵车间和提炼车间。CODcr高达2280mg/L,BOD5:1150mg/L,B/C=0.504,可见该废水的生化性能较好。另外动植物油达50mg/L,虽说排放标准动植物油是100mg/L,但是油的存在会影响到后续生化处理,所以有必要对油进行处理。此外工业废水一般具有高SS浓度,毒性等,由于该厂采用生物发酵工艺制药,因此,废水呈酸性。
采用厌氧+好氧的组合生化工艺来处理该废水,废水经处理达到《中药类制药工业水污染排放标准》(GB21906-2008)标准后,排入市政管网,一方面达到了环境保护的要求,另一方面减轻了城市污水厂的处理负荷;提升了大邦制药的对外形象。
项目建成后,大邦生物制药生产基地每年可减少排放CODcr达1108吨,BOD5达557吨,从而可以减少缴纳排污费用;并且通过项目的实施,使企业达到环境质量体系的要求,带来更多的附加经济效益。
