摘要
针对半导体行业产生的含氟废水,采用混凝沉淀和活性氧化铝组合工艺,对该生产废水进行处理,首先通过混凝沉淀去除大部分污染物,然后利用活性氧化铝吸附剩余的污染物。工程实践表明:系统维持相对稳定的情况下,出水水质指标达到了《污水综合排放标准》(GB 8978-1996)一级标准。
The engineering application of the combined process of coagulation-alumina adsorption for processing of the Fluoride-containing wastewater in semiconductor plant was introduced.The coagulating sedimentation and alumina adsorption was adopted to meet the requirement of fluoride-containing wastewater.The actual results showed that,with maintaining stable condition,the effluent quality meetsⅠ-class criteria specified in the Integrated Wastewater Discharge Standard(GB 8978-1996).
