摘　　要：本研究是以山东淄博某厂脱墨废水为处理对象,以臭氧发生器自制臭氧水为主,用过氧化氢、活性炭、硫酸铝、聚丙烯酰胺、二氧化锰协同处理,再结合絮凝沉降,吸附,过滤,处理后的污水完全达到循环利用的标准。通过实验发现,臭氧单独处理污水,在常温(20℃)PH为6.91条件下,连续处理污水70min后,污水的COD、BOD、TOC、SS和色度分别从原来的2660mg/L、1962mg/L、1165mg/L、707mg/L和120倍降低到1308mg/L、1108mg/L、142mg/L、80mg/L和50倍。相应地,用臭氧-催化氧化-过氧化氢-活性炭-絮凝剂-过滤的方法对该污水进行处理,在常温(20℃)PH为6.65条件下,通入臭氧70min,过氧化氢用量60mmol/L、活性炭用量220mg/L、硫酸铝用量25mg/L、聚丙烯酰胺用量15mg/L、二氧化锰用量10mg/L条件下,污水的COD、BOD、TOC、SS和色度分别降低到384mg/L、401mg/L、74mg/L、39mg/L和30倍。This study is a factory waste paper pulping deinking wastewater of Shandong Zibo as treatment object, with ozone generator homemade ozone water, hydrogen peroxide, activated carbon, aluminum sulfate, polyacrylamide, manganese dioxide co-processing, combined with flocculation and sedimentation, adsorption, filtration, sewage after treatment fully meet the standard recycling.Experimental findings show that the ozone-water continuous separate treatment wastewater at temperature (20℃) and pH 6.91 for 70min,COD, BOD, TOC, SS, and chroma of wastewater is respectively from the original 2 660mg/l, 1 962mg/l, 1 165mg/l, 707mg/l and 120 times reduced to 1 308mg/l, 1 108mg/l, 142mg/l, 80mg/l and 50 times. Accordingly,the ozone-water with ozone-catalytic oxidation - activated carbon - hydrogen peroxide-flocculant–filtration to co-treatment wastewater at temperature (20℃) and pH 6.65 condition for 70min, COD, BOD, TOC, SS and chroma of wastewater respectively reduced to 384mg/l, 401mg/l, 74mg/l, 39mg/l and 30 times by method of using hydrogen peroxide 60mmol/l, activated carbon 220mg/l, aluminum sulfate 25mg/l, PAM 15mg/l, manganese dioxide 10mg/l of wastewater.
