摘要
针对某日用化工企业排放的高浓度有机废水,采用"气浮-UASB-A/O"联合工艺进行处理。设计处理能力为120t/d。工程实践表明:当进水COD为5500 mg/L左右时,系统维持相对稳定的情况下,出水水质可达到《污水综合排放标准》(GB 8978-1996)的一级标准要求,废水处理的运行成本在合理范围内。
The wastewater discharged from daily chemical industry contains a large quantity of organisms.It is characterized by complicated components.The combined air flotation-UASB-AO process has been used for its treatment.The practice proves that when the influent COD is about 5500 mg/L,and the system remains relatively stable condition,the effluent water quality meets the requirements for the First Level standard specified in the Integrated Wastewater Discharge Standard(GB 8978—1996).
