混凝沉淀—生物法—高级氧化处理颜料废水工程应用

Engineering application of coagulation precipitation-biological processadvanced oxidation process to the treatment of pigment wastewater

某颜料企业针对其排放的高浓度有机废水,采用混凝沉淀—生物法—高级氧化的组合工艺进行处理。工程实践表明:在系统维持相对稳定的情况下,经处理后的出水水质达到了《污水综合排放标准》(GB 8978—1996)的一级标准要求。

Aiming at the problems that the wastewater from a pigment enterprise contains highly concentrated organics,the combined process coagulation precipitation-biological method-advanced oxidation,has been used for its treatment. The engineering practice shows that when the systems conditions keep relatively stable,the effluent water quality can meet the requirements of I-class criteria specified in the Integrated Wastewater Discharge Standard（GB8978—1996）.
