摘要:以广西某无碳复写纸生产企业为例，对该企业的无碳复写纸涂料废水采用一级物化（高效废水净化器）、生化（塔式生物滤池）和深度氧化（Fenton氧化法）相结合的处理工艺。结果表明，该工艺对无碳复写纸涂料废水的COD_Cr去除率达97.8%、BOD₅去除率达98.3%、SS去除率达95.9%，处理后的废水水质指标均达到了GB 3544—2008规定的排放标准。

Abstract:Taking a carbonless copy paper manufacturer in Guangxi as an example， the wastewater of carbonless copy paper coating was treated with a combination of primary physicochemical method （high-efficiency wastewater purifier）， biochemical method （tower biological filter） and deep oxidation （Fenton oxidation）.The results showed that COD_Cr removal rate of this process was 97.8%， the BOD₅ removal rate was 98.3%， and the SS removal rate was 95.9% for wastewater of carbonless copy paper coating.All of quality indicators of the treated wastewater met the discharge standards stipulated in GB 3544—2008.
