| 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 CODCr 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. |
