IC反应器处理化学合成类制药废水的工程应用

Engineering Application of IC Reactor for Treatment of Chemical Synthesis Pharmaceutical Wastewater

结合医药行业废水特点与相关废水处理案例,并考虑用户实际需求,将第三代厌氧生物反应器(IC反应器)应用在工业制药废水处理中。工程实践表明,在容积负荷为5.0 kg/(m^(3)·d)的条件下,COD去除率可达50%以上。系统容积负荷宜控制在4.5 kg/(m^(3)·d)~5.0 kg/(m^(3)·d),反应器内温度宜保持在37℃~40℃,pH控制在6.5~7.5,挥发性脂肪酸(VFA)浓度不宜高于10 mmol/L,COD/ρ(SO_(4)^(2-))宜大于10。

Combining the characteristics of wastewater in the pharmaceutical industry and related wastewater treatment cases,and considering the actual needs of users,the third-generation anaerobic bioreactor(IC reactor)was applied to the treatment of industrial pharmaceutical wastewater.Engineering practice showed that the COD removal efficiency can reach more than 50%under the condition of a volume load of 5.0 kg/(m^(3)·d).The volume load of the system should be controlled at 4.5kg/(m^(3)·d)~5.0 kg/(m^(3)·d),the temperature in the reactor should be kept at 37℃~40℃,the pH should be controlled at 6.5~7.5,the concentration of volatile fatty acids(VFA)should not be higher than 10 mmol/L and COD/ρ(SO_(4)^(2-))should be greater than 10.
