摘要
制药废水通常具有组成复杂、有机污染物种类多、浓度高、B/C比值低的特点。针对这些特点,采用两段水解酸化-好氧法工艺处理制药废水的小试研究。试验结果表明,污染物去除率COD>83%、NH3-N>84%、BOD5>95%,有效地削减了制药废水的排污量,减少污染。
Generally,pharmaceutical wastewater has such characteristics as complicated elements,intricate species of organic pollutant,high concentration,and low ratio of BOD and COD.Base on analyzing the water features,two-stage hydrolytic acidulation with aerobic process was studied to treat pharmaceutical wastewater.Experimental results showed that the removal rates of COD>83%,NH3-N>84%,BOD5>98%,which would reduce availably the pharmaceutical wastewater exhaust and decreased the pollution.
