摘要
针对高浓度制药废水成分复杂、可生化性较差等特点,采用铁碳微电解/混凝/臭氧氧化工艺作为预处理工艺,再与生物处理工艺联用进行处理。介绍了各处理构筑物的设计参数及设备配置情况,并对实际运行效果进行了分析。结果表明,铁碳微电解/混凝/臭氧氧化预处理可去除50%以上的COD,有效降低了后续生物处理工艺的有机负荷。整个处理系统运行稳定,COD总去除率>95%,出水水质满足当地污水处理厂的纳管要求。
Considering the complex quality and poor biodegradability of high concentration phar- maceutical wastewater, the combined process of iron-carbon micro-electrolysis, coagulation, ozonation was first used to pretreat the wastewater, and then the biological treatment process was applied. The de- sign parameters, equipment allocation and treatment effects were introduced. The results showed that the micro-eleetrolysis/coagulation/ozonation process could obviously reduce the organic loading rates for the subsequent biological treatment system, with COD removal being higher than 50%. Furthermore, the COD removal efficiency was achieved above 95% in the total treatment system, and the final effluent could meet the requirements of influent quality for the local municipal sewage plant.
