摘要
考虑到高浓度原料药生产废水具有高COD、高毒性、可生化性差的特点,单纯采用生化处理工艺很难使出水水质稳定达标排放,首先采用铁碳微电解和Fenton氧化工艺对原料药废水预处理,再通过厌氧-好氧-臭氧氧化等多级组合工艺进行深度处理.经过多次中试试验,验证该组合工艺具有经济和技术的可行性,出水水质的COD浓度可达到60 mg/L以下,并为实际工程工艺稳定运行提供最优参数.
Abstract
Considering the characteristics of high concentration raw material production wastewater with high COD,high toxicity,and poor biodegradability,it is difficult to achieve stable and up-to-standard discharge of effluent water solely using biochemical treatment processes.Firstly,iron carbon microelectrolysis and Fenton Oxidation processes are used to pretreat raw material wastewater,and then multi-stage combination processes such as anaerobic-aerobic-ozone oxidation are used for deep treatment.Through multiple pilot tests,the economic and technical feasibility of this combination process is verified,with the COD concentration in the effluent water below 60 mg/L,and optimal parameters are provided for the stable operation of actual engineering processes.
