摘要
采用絮凝 -氧化 -吸附法联合处理邻硝基苯胺生产废水 ,用硫酸亚铁作絮凝剂 ,过氧化氢作助氧剂 ,温度为 70～ 80℃ ,通氧或鼓空气氧化 3～ 4h,然后用 CHA1 0 1树脂吸附处理 ,原废水 CODCr为 5 2 0 0 mg/L,色度为 1 6 0 0 0 ,处理后废水 CODCr降至 80 mg/L以下 ,色度降至
The wastewater from the production of o-nitro phenyl amine was treated by the method of coagulation-oxidization-adsorption, using ferric sulfate as a coagulant and hydrogen peroxide as an oxidization aid as well as adopting the adsorption process with CHA101 resin, the COD Cr and colority of raw wastewater with 5200mg/L of COD Cr and 16000 of colority can lower to below 80 mg/L and 40 respectively.
