摘　　要：采用碱中和沉淀氧化工艺对广东省某氧化铁红厂酸性含Fe2废水进行处理,并收集沉淀污泥作为晶种生产氧化铁红产品.经调试运行后,系统出水pH值为8.5 ～9.0,对Fe2＋和SS的总去除率分别为99.86％、84.65％,色度＜40倍,满足《污水综合排放标准》（GB 8978-1996）一级标准,同时以沉淀污泥作为晶种生产的氧化铁红产品符合130#氧化铁红质量标准.The alkali neutralization and precipitation process was used to treat the acid wastewater with high Fe2＋ content from an iron oxide red factory in Jiangmen City,Guangdong Province.The settled sludge was used as a seed crystal to produce iron oxide red products.After the commissioning and operation,the pH value of effluent was 8.5 to 9.0,the total removal rates of Fe2 ＋ and SS were 99.86％ and 84.65 ％ respectively,and the color was less than 40 times.The effluent quality met the first class criteria specified in the Integrated Wastewater Discharge Standard （GB 8978-1996）,and the iron oxide red produced from settled sludge as seed crystal met the standard of 130# iron oxide red.
