Abstract:

Highly concentrated pharmaceutical wastewater has been pretreated by evaporation first to remove sulphur and inorganic salt thoroughly. Then a series of aerobic,anaerobic and anaerobic-aerobic treatment are carried out combinedly. The concentration of the COD of influent water changes from 2.8 ×104 mg/L to less than 300 mg/L because of the degradation of different microorganisms. After a 5 month stable running,the project was smoothly through the acceptance check fromZhengzhou Environmental Protection Bureau on January 12,2005.

摘要：

对高浓度制药废水首先进行浓缩蒸发预处理,彻底除硫除盐以后,再通过一系列的厌氧、兼氧、缺氧-好氧组合处理,充分发挥在不同环境条件下各类微生物代谢降解有机污染物的功能,使废水中COD由2.8×104mg/L降到300mg/L以下,经过5个月的稳定运行后,于2005年1月12日顺利通过郑州市环保局组织的达标验收。
