摘要
采用微电解/芬顿/水解酸化/生物接触氧化/混凝工艺处理化学合成类制药废水,处理规模为100 m~3/d。运行结果表明,该工艺处理效率高,抗冲击负荷能力强,对COD、BOD_5、NH_3-N、SS的去除率分别达到98. 5%、98. 7%、84. 0%、97. 0%,出水COD、BOD_5、NH_3-N、SS浓度分别为77、13、8、9 mg/L,最终出水水质达到《化学合成类制药工业水污染物排放标准》(GB 21904—2008)。
The combined process of micro-electrolysis,Fenton,hydrolysis acidification,biological contact oxidation and coagulation was applied to treat chemical synthetic pharmaceutical wastewater. The treatment capacity was 100 m~3/d. The running results showed that the combined process had high treatment efficiency and strong resistance to shock loading. The effluent concentrations of COD,BOD_5,NH_3-N and SS were 77 mg/L,13 mg/L,8 mg/L and 9 mg/L with the remove rate of 98. 5%,98. 7%,84. 0% and 97. 0% respectively. The final effluent water quality could meet the Discharge Standards of Water Pollutants for Pharmaceutical Industry Chemical Synthesis Products Category( GB 21904-2008).
