摘要：

对铁还原 -混凝沉淀 -水解酸化 -接触氧化串联工艺处理氟化工废水进行了系统的研究。含 6 0 %生活污水的氟化工废水,经该工艺处理出水总磷已达到GB8978— 1996《污水综合排放标准》二级标准,COD_Cr、BOD₅、SS、pH值都已达到一级标准,氨氮低于检测限。

Abstract:

The treatment process of fluorizated hydrocarbon wastewater has been systematically studied. The result of this research indicates that the ferrite reduction- neutralization- coag ulation precipitation pretreatment, combined with incomplete anaerobic process and bio-contact oxidation process is effective for this wastewater.COD_Cr, ammonia nit rogen, BOD₅, SS, pH of the final effluent can meet the First Demand of National Discharge Standard and TP can meet the Secondary one.

Key words: fluorine-containing wastewater, ferricaeration reduction process, coagulation precipitation process hydrolysis-acidif icat ion, contact oxidat ion process
